Zero trust is a cybersecurity approach that applies security policy on the basis of context created by stringent user authentication and least-privileged access rules, rather than on the assumption of trust. Improved cyberthreat defense, easier network architecture, and enhanced user experience are all results of a well-tuned zero trust architecture.
An architecture with zero trust adheres to the adage “never trust, always verify.” Since the word was first used by John Kindervag at Forrester Research, this guiding principle has been in effect. In order to prevent unauthorized access and lateral movement around an environment, a zero trust architecture enforces access regulations based on context, which includes the user’s role and location, their device, and the data they are requesting.
In order to establish a zero trust architecture, it is necessary to monitor and verify traffic between different parts of the environment, have visibility and control over users and traffic, including encrypted traffic, and use strong multifactor authentication (MFA) techniques other than passwords, like biometrics or one-time codes.
Importantly, a resource’s network location no longer determines its security posture to the same extent in a zero trust architecture. Your data, workflows, services, and other elements are safeguarded by software-defined micro-segmentation as opposed to strict network segmentation, allowing you to maintain their security everywhere—in your data center or in dispersed hybrid and multi-cloud settings.
As a core concept, zero trust assumes every component or connection is hostile by default, departing from earlier models based on secure network perimeters. This lack of trust is technologically defined by:
- The underlying architecture: Traditional models used approved IP addresses, ports, protocols for access controls and remote access VPN for trust validation.
- An inline approach: This considers all traffic as potentially hostile, even within the network perimeter. Traffic is blocked until validated by specific attributes such as a fingerprint or identity.
- Context-aware policies: This stronger security approach remains with the workload regardless of where it communicates—be it a public cloud, hybrid environment, container, or on-premises network architecture.
- Multifactor authentication: Validation is based on user, identity, device, and location.
- Environment-agnostic security: Protection applies regardless of the communication environment, promoting secure cross-network communications without the need for architectural changes or policy updates.
- Business-oriented connectivity: A zero trust model uses business policies for connecting users, devices, and applications securely across any network, facilitating secure digital transformation.
What are the Components of the Zero Trust Model?
The goal of the zero trust security paradigm is to make sure that all access requests are valid before granting them. Permissions can be assigned to any user, application, or device in an organization, and access requests are assessed in accordance with these permissions.
A zero trust security architecture needs to be able to intercept and examine each request in order to guarantee that every access request is authenticated. Microsegmentation does this by enclosing each application or system in a trust boundary. An organization can manage access to a resource at a granular level by requiring authentication for requests to cross the border.
A security system known as zero trust is based on a few fundamental ideas. A zero trust architecture usually consists of the following fundamental components and applies these ideas in a practical way.
Microsegmentation
A zero trust architecture evaluates each access request against policy controls before approving or denying it. To do so, it needs the ability to intercept, evaluate, and allow or block access requests en route to their destination.
Microsegmentation creates network boundaries around an organization’s IT assets using software-defined networking (SDN). The system can evaluate access requests at these boundaries and approve or deny them as needed.
Multi-Factor Authentication (MFA)
A zero trust architecture depends on the ability to accurately determine the identity of a user, device, or application. Once it has done so, it can apply the appropriate access controls and policies to the request.
Multi-factor authentication (MFA) offers stronger user authentication than passwords or other single-factor authentication solutions. By requiring multiple authentication factors, MFA reduces the risk that attackers can compromise and use a legitimate account in their attacks.
Zero Trust Network Access (ZTNA)
A zero trust framework should support an organization’s users and IT systems. This includes on-prem and off-site devices, remote workers, and the cloud.
Zero trust network access (ZTNA) offers secure remote access that complies with zero trust principles. Users are only granted access to applications and systems that they legitimately need rather than the corporate network as a whole.
Real-Time Monitoring and Enforcement
Zero trust introduces security and access management into the process of accessing any corporate IT resource. Instead of inherently trusting insiders, a zero trust framework applies the “never trust, always verify” principle.

To do so, the system needs support for real-time monitoring and policy enforcement. Traffic crossing the boundaries defined by microsegmentation should be inspected and evaluated without significantly impacting system performance or the user experience.
Identity, devices, networks, apps & workloads, and data are the five primary pillars of zero trust, according to the Cybersecurity and Infrastructure Security Agency (CISA). An organization’s zero trust program develops over time as it builds more complex procedures and solutions for each of these pillars as well as those that span them.
CISA identifies four key developmental stages that businesses go through as they progress toward zero trust, including:
- Traditional: At this stage, a company primarily relies on manual processes to implement zero trust and least privilege at provisioning and focuses on one of the five pillars at a time.
- Initial: The organization begins to automate identity management processes, implements cross-pillar solutions, and updates and adapts least privilege access controls after provisioning.
- Advanced: The organization uses automation when applicable to manage cross-pillar configurations and policies and response to certain incidents, achieves centralized visibility and identity management, and uses risk assessments to update least privilege controls and policies.
- Optimal: The organization achieves fully automated attribute management, self-reporting, least privilege access control, and continuous monitoring.
Where is the Zero Trust Model Used?
Extremely detailed control over an organization’s IT resources is provided by zero trust security. This can be applied to a number of business difficulties, such as the following:
Secure Remote Work
As remote and hybrid work grows more common, it introduces additional cybersecurity risks to an organization. Remote endpoints may lack the same protections as on-site devices and be vulnerable to malware infections or account takeover attacks.
Zero trust limits the potential risks of a compromised remote worker’s computer or account. Even if an attacker gains access to an organization’s environment, every access request is evaluated against corporate policy, increasing the difficulty of performing malicious actions.
Cloud Security
Companies are increasingly moving data and applications to cloud environments. While this has its benefits, it also introduces additional cybersecurity risks and complexity.
One of the main challenges of cloud security is managing access within and across cloud environments. Implementing a zero trust security policy enables an organization to enhance and standardize cloud access management policies.
Internet of Things (IoT) Security
Internet of Things (IoT) devices are also a growing part of corporate cloud environments. This includes both consumer IoT devices — such as smart thermostats or Internet-connected cameras — and industrial IoT devices designed to control manufacturing systems.
Often, these IoT devices have poor security and can act as an entry point for an attacker to gain access to the corporate IT environment. Zero trust security helps to lock down access to and from these devices, minimizing their potential threat to the organization.
Third-Party Risk Management
In addition to employees, companies commonly grant third parties access to their environments. This includes contractors, vendors, and partners who have a legitimate need to access, manage, or monitor certain systems.
This third-party access introduces the potential for supply chain attacks in which an attacker with access to a partner’s environment leverages their access to target an organization. With zero trust security, an organization can limit these third parties’ access to the minimum necessary, decreasing the potential risk and implications of a supply chain attack.
Threat Detection and Response
Cyber threat actors use various methods to access an organization’s environment and achieve their malicious goals. Account takeover attacks — enabled by phishing or malware — are a common method for cybercriminals to gain initial access to a target environment.
Zero trust limits the risk of account takeover attacks and can expedite the process of identifying and remediating cyber threats. With visibility into every request for access to corporate resources, a security team likely has multiple opportunities to identify and block a data breach or other security incident before it occurs.
Regulatory Compliance
Regulatory compliance is a major concern and significant challenge for many organizations. With large volumes of data scattered across multiple locations, it can be difficult to track and manage access to sensitive, protected data.
Zero trust helps an organization to maintain and demonstrate regulatory compliance due to the visibility it provides into requests for access to corporate resources. The ability to individually authenticate each access request provides opportunities to block unauthorized ones, and access logs from zero trust systems can be invaluable for demonstrating compliance or investigating a successful data breach.
How do you Create a Zero Trust Strategy?
An organization’s security procedures and controls are arranged according to zero trust principles in a zero trust strategy. It guarantees that all users, both inside and outside the network of your company, must be authenticated, authorized, and regularly confirmed in order to access apps and data.
A zero trust security approach tackles the difficulties presented by the complicated IT environment of today. It can offer answers for issues like:
- Securing corporate environments that do not have a clearly defined perimeter
- Defending identities (such as user accounts and service accounts), is possibly the biggest attack surface in the modern enterprise
- Protecting remote workers and the assets they access
- Storing data across hybrid and multi-cloud environments
- Preventing lateral movement and privilege escalation
- Enforcing security measures like strong authentication and encryption
- Protecting against malware and other risks from unmanaged, personal devices
Because data breaches are becoming more frequent and severe, it is crucial for businesses to have a proactive security strategy in order to safeguard their data. Because breaches can occur from within the business, traditional security systems that accept everything internal as trusted and concentrate defensive measures outward are no longer sufficient.
While implementing a new security strategy might be difficult, zero trust offers an easy-to-use, scalable solution to strengthen an organization’s defenses. Because standard security measures like VPNs and firewalls implicitly trust all entities within the protected network, they are not impervious to hostile insiders or human error. As soon as an attacker has access to a network, they can take advantage of sensitive data.
Attackers that have gained access to the system with zero trust are unable to progress laterally or carry out destructive operations. Every resource is completely protected both inside and outside. By default, everything is closed, and access is granted only upon necessity. Additionally, it lessens the workload for programmers and IT teams who create safe apps by distributing security responsibilities throughout the entire company and putting in place pervasive access controls.
Below are 7 Steps to Building Your Zero Trust Security Strategy:
1. Use Identities to Control Access
Identities (representing people or service accounts) are a common denominator throughout an organization’s networks, applications, and endpoints. The zero trust security model is a granular and flexible way to control data access. New boundaries created by zero trust systems are based on strong, validated identities.
When an identity requests access to a resource, the security controls use strong authentication to verify that identity and ensure the access request complies with the organization’s policies, and that the relevant identity is accessing resources according to the least-privilege principle, and that the access attempt is not anomalous.
2. Adopt a User-Centric Approach
At the heart of the zero trust concept is understanding the transfer of responsibility to end-users, and the need to emphasize security at the user level. End-users should be empowered to access the resources they need, and should be accountable for their actions after gaining access.
End-users should have access to self-service systems that can help them enroll devices in MFA and install certificates. They should be made responsible for patching personal devices to the level required for access, and complying with other relevant security policies.
3. Incorporate Passwordless Authentication
Passwordless authentication replaces a traditional password with an authentication factor protected by two or more pairs of cryptographic keys. After registration, the device generates a public key and a private key. It is possible to unlock the private key using a mechanism like a PIN sent to a mobile device or via biometric authentication.
4. Segment Your Corporate Network
Firewalls are an existing form of segmentation in most organizations, but the segmentation they provide is not sufficiently granular to implement zero trust.
For zero trust, it is critical to implement deeper microsegmentation within the network, because in a mobile and cloud-first ecosystem, all access to business-critical data is through network infrastructure. Network controls compatible with zero trust principles can increase visibility and help stop attackers from moving laterally through your network.
5. Segment Your Applications
It is important to find the appropriate balance between providing smooth access and maintaining controls to protect applications and their data. Apply security controls and scanning technologies to identify shadow IT, enforce proper in-app permissions, block access according to real-time analytics, restrict certain user actions, monitor network activity for anomalous behavior, and verify secure configuration options.
6. Secure Your Devices
In the zero trust model, it is important to secure access from any device—whether it is company-owned or personally-owned (known as Bring Your Own Device or BYOD), and whether it is accessing systems from within the corporate network or over public networks.
Employees, contractors, partners and guest devices are all subjected to security checks—whether IT fully manages the device or only protects applications and data. This is true regardless of whether the endpoints (PCs, Macs, smartphones, tablets, wearables, or IoT devices) use a home broadband, secure corporate network, or public Internet connection.
7. Define Roles and Access Controls
With the growth in remote work, companies must consider alternatives to implementing modern security controls. Enabling roles and associating them with policies is critical for authorization, passwordless access, single sign-on, and segmentation. However, each defined role creates management overhead, so you should carefully organize and limit the number of roles you define.
Pros and Cons of the Zero Trust Security
Businesses struggle constantly to maintain their security policies and procedures up to date with the evolving dangers as threat actors grow more and more skilled. The complexity of the technological environment increases the attack surface, which gives hackers more chances to wreak havoc on a large scale.
One effective method to combat this is the zero trust model. Zero trust, which is based on the idea that “never trust, always verify,” is revolutionizing how businesses manage network visibility and access control. Zero trust, like any security architecture, offers benefits and drawbacks of its own.
Pros
Naturally, improved network security and defense against both external and internal threats is the main advantage of zero trust. Additionally, it’s a scalable solution for remote and hybrid work settings.
- Enhanced security
By granting access strictly on a need-to-know basis, zero trust minimizes the attack surface and makes it substantially more challenging for potential intruders to gain unauthorized access. This heightened level of security is particularly beneficial in today’s technological landscape, where cyberthreats are becoming not only more pervasive but also more sophisticated.
- Improved visibility and control
Zero trust security provides organizations with a granular view of their network activities. It enables them to monitor who is accessing what resources, at what time, and from which location. This level of control is crucial in promptly detecting any unusual activity, thereby preventing potential data breaches and other security incidents.
With improved visibility, organizations can also better understand their network operations, identify potential vulnerabilities, and make informed decisions about resource allocation and risk management.
- Reduced risk of insider threats
Insider threats, whether malicious or accidental, are quite risky to organizations. The zero trust model mitigates this risk by applying the same stringent access controls to all users, regardless of their position within the organization. This ensures that even if an insider’s credentials are compromised, the potential damage can be contained.
By treating every access request as potentially risky, zero trust security significantly reduces the likelihood of insider threats leading to data breaches.
- Data protection
Reducing attack surfaces and restricting data access through segmentation does not safeguard organizations from data leaks, security breaches, and interception if they fail to secure their data in transit and storage.
The zero trust model provides robust protection for data by ensuring that access is granted only to those who need it for their specific tasks. This approach not only prevents unauthorized access but also reduces the risk of data being moved or copied without permission.
With zero trust, organizations can ensure their sensitive data is secure during storage and transit, helping them comply with data protection regulations and maintain customer trust.
- Adaptability to modern work environments
The zero trust model is highly adaptable to modern work environments, which often involve remote work and the use of personal mobile devices. By verifying every access request regardless of its origin, zero trust security can accommodate flexible work arrangements without compromising security.
Cons
Although the additional security provided by zero trust is clear, the practice does have some drawbacks, such as complex implementation and resource usage, and potentials for frustration stemming from cumbersome login processes and false positives.
Complex implementation
The implementation of a zero trust security model can be a complex and daunting task. It requires a comprehensive understanding of the network’s intricacies, including all users, devices, applications and data.
Plus, it may require substantial changes to the existing security infrastructure, which can be disruptive and costly. Organizations need to be prepared for the time and resources required to successfully implement a zero trust model.
Potential for user frustration
The rigorous access controls of a zero trust model can potentially lead to user frustration. Employees may find the continuous verification processes cumbersome, especially if they hinder their ability to perform their tasks efficiently.
This could lead to resistance to adopting the zero trust model and in some cases, employees might attempt to bypass security controls, inadvertently creating new vulnerabilities. Zero trust compliance enforcement companies such as Kolide can help ensure your employees are using the correct approach — without creating additional hassle for them or you.
Increased strain on resources
Implementing and maintaining a zero trust model can be resource-intensive. It requires continuous monitoring and management of network activities, which can put a strain on an organization’s IT resources.

Additionally, the need for advanced security tools and technologies can lead to increased costs. Organizations need to factor in these resource demands when considering a zero trust approach.
Potential for false positives
Given the stringent nature of zero trust security, there’s a risk of false positives, where legitimate users or activities are flagged as suspicious. This can disrupt workflows and lead to unnecessary investigations, wasting time and resources. While false positives can be reduced with fine-tuning, they remain a challenge in the zero trust model.
Dependency on technology
Zero trust security is heavily dependent on technology, including advanced security tools and technologies for identity verification, encryption and network segmentation. If these technologies fail, they can leave the organization vulnerable. As technology evolves, there may be a need for continuous upgrades and investments to keep the zero trust model effective.
Overcoming the Issues With Zero Trust
Despite these challenges, there are various methods to mitigate the issues associated with building a zero trust network, and still reap the benefits.
Gradual implementation
One of the strategies to overcome the challenges associated with zero trust is to implement it gradually.
Instead of trying to overhaul the entire network security at once, organizations can begin by applying the zero trust model to a small part of their network. This could be a particular department, a specific type of data, or a certain set of applications.
Gradual implementation allows organizations to learn and adapt as they go, reducing the risk of disruption and making the transition more manageable.
Investing in user-friendly solutions
There are many zero trust security tools and technologies available today that are designed with user experience in mind. These solutions make the verification processes as seamless as possible, minimizing disruption to user workflows. By choosing user-friendly solutions, organizations can ensure that their employees are more likely to embrace the zero trust model.
Regular training and communication
Regular training and communication are crucial in overcoming the challenges of zero trust. Employees need to understand why the organization is adopting a zero trust model, how it works, and what they need to do to be compliant.
Regular training sessions can help employees understand the importance of zero trust and how it protects the organization. Clear and consistent communication can also help to alleviate any concerns or resistance among employees.
Resource planning
To manage the increased demand on resources associated with zero trust, organizations need to plan their resources carefully. This includes not only financial resources for investing in necessary tools and technologies but also human resources for managing and monitoring zero trust deployments. Organizations may need to consider hiring additional IT staff or training existing staff to handle the increased workload.
Continuous refinement
Finally, overcoming the challenges of zero trust requires continuous refinement. This includes regularly reviewing and adjusting access controls, monitoring for false positives, and updating technologies as needed.
By continuously fine-tuning their zero trust model, organizations can ensure that it remains effective and efficient in the face of evolving threats and changing business needs.
What are the Security Models in Cybersecurity?
Information security models are frameworks that define who should have access to what information and how the operating system should function in order to allow management to set up access control. The models support the selected implementation by providing a mathematical mapping of theoretical objectives.
A security model could be based on a formal computing model, a distributed computation model, an access rights model, or even a model of distributed computation, or it could have no theoretical foundation at all.
The core aim of any security model is to maintain the goals of Confidentiality, Integrity, and Availability of data. It can achieve these goals by:
- Allowing admins to choose the resources to that users are allowed access.
- Verifying user identities with authentication mechanisms that incorporate password strength and other variables.
- Allowing users who have been permitted to access resources provisioned and defined by authorization systems.
- Regulating which functions and rights are given to accounts and users.
- Giving admins access to a user’s list of activities on a request or assignment basis.
- Safeguarding private data, such as account characteristics or user lists.
Many security models have been put forth throughout history since network and cyber security are fields that are always changing. Nonetheless, a number of alternative models are built upon the three traditional security models. Let’s examine them in more detail:
1. Bell-LaPadula
David Bell and Leonard LaPadula, pioneers in computer security, created the Bell-LaPadula model, a lattice-based security concept, in the 1970s. The Bell-LaPadula model is a multilevel security system. It establishes a set of access rules and security levels (such as Top Secret, Secret, and Confidential) that specify how individuals may access objects at various security levels.
Bell-LaPadula only allows users at or above their own security level to create content. However, users are limited to seeing anything that is at or below their own security level.
When sensitive information has to be shielded from unwanted access, military and government institutions commonly employ the Bell-LaPadula model. It is sometimes employed in civil organizations, such as banks and hospitals, where a robust cyber security architecture and data protection are vital.
Rules of the Bell-LaPadula model:
- SIMPLE Confidentiality Rule: Simple Confidentiality Rule specifies that the Subject may only read documents protected by the same layer of secrecy and the lower layer of secrecy, but not the upper layer of secrecy. For this reason, we refer to this rule as NO READ-UP.
- STAR Confidentiality Rule: According to the Star Confidentiality Rule, the Subject may only write files on the same layer of secrecy and the upper layer of secrecy, but not the lower layer of secrecy. For this reason, the rule is known as NO WRITE-DOWN.
- STRONG STAR Confidentiality Rule: The Strong Star Confidentiality Rule is the strongest and most secure, stating that the Subject may only read and write files on the same layer of secrecy and not on an upper or lower layer of secrecy. Because of this, the rule is known as NO READ WRITE-UP OR DOWN.
- Significance of the Bell-LaPadula Security Model
Being among the earliest modern security models to be created, the Bell-LaPadula model is important. This model has influenced the creation of many security models. The lattice-based security model structure of the Bell-LaPadula model has additional relevance because it was unique when it was first developed.
The Bell-LaPadula model is a key security tool that fulfills several functions. The concept initially sets several security layers to protect information from unauthorized access. The model gives a technique for controlling access to information at multiple security levels by offering a set of access rules that govern how subjects can access objects at different degrees of security. The methodology may also be used to audit information access and ensure that no unauthorized access occurs.
2. Biba model
The Bell-LaPadula Model’s shortcomings inspired the development of the Biba Model. Data integrity is not addressed by the Bell-LaPadula paradigm; only data confidentiality is.
The Biba Model, which articulates a set of access control rules for maintaining data integrity, is a formal state transition system for data security regulations. Data and subjects are organized or categorized according to how reliable they are. Biba aims to prevent data corruption at levels rated higher than the topic and minimize data corruption at levels rated lower than the subject.
- Rules of the Biba Model:
- No Write-Up (Integrity Axiom): According to this rule, no one is permitted to add to or change data that has a lower integrity level. This guards against low-quality sources, tainting information of high quality.
- No Read Down (Simple Security Property): A user cannot read an item with a higher integrity level, as per this rule. This suggests that the data you are allowed to access is not more important than the data you are not allowed to see or read. For example, in a school, a student would never need access to the principal’s file.
- Importance of the BIBA model: The Biba Model is a collection of rules for a computer system that aids in maintaining valid and secure data. The name comes from Kenneth J. Biba’s proposal in 1977. The Biba Model’s main goal is to prevent people without the necessary authorization from tampering with data.
The model implements stringent integrity-based access restrictions. While users are prevented from downgrading data integrity, they are also prevented from accessing data from higher integrity levels. This ensures data isolation and confidentiality.
3. Clark-Wilson model
The Clark-Wilson security model is built upon protecting information integrity from hostile data-altering attempts. The security model states that the system should maintain consistency between internal and external data and that only authorized users should be able to generate and alter data—unauthorized users should not be able to do so at all.
The primary goal of this model is to formalize the idea of information integrity by preventing data corruption in a system due to errors or malicious intent. An integrity policy specifies how the system’s data items should behave to maintain their validity when they change from one system state to another. The model outlines certification and enforcement procedures as well as the capabilities of the principals deployed inside the system.
The Clark-Wilson security concept prohibits direct access to constrained data objects. You can use these two processes to access constrained data objects:
- 1. Transformation process
Constrained data items can be requested by the user and managed by the transformation process. This process is intended to ensure that data changes maintain data integrity and follow the prescribed certification standards. It is transformed into authorization by the procedure before being sent to the integration verification procedure.
- 2. Integration verification process
It carries out authentication and permission. The user is granted access to the restricted data items if this verification is successful.
4. Brewer and Nash Model
The Brewer and Nash model, also known as the ‘Chinese Wall Model’ is built to establish a set of rules to minimize conflict of interest. It aims to prevent access to any sensitive information that could lead to significant consequences because of personal interest conflict.
The model advocates for data segregation and dynamic access controls. Dynamic acces controls are decided based on the user’s previous interaction with the critical information. The model is however not as widely used as other models.
5. Harrison Ruzzo Ullman Model
The Harrison Ruzzo Ullman Model (HRU) is established to address security concerns related to information flow . Unlike the BLP model which is based on mandatory access control, the HRU model adopts discretionary access control. It utilizes an access matrix to understand permissible actions that subjects (such as users) can perform on objects (such as files).
Benefits of a Security Model
Implementing an extensive security model has several advantages. Let’s look into the top advantages that a security model can provide you:
1. Accurate infrastructure inventory
A security model demands administrators to understand which people, devices, data, apps, and services are part of the business infrastructure and where they are located. In addition to assisting with security-related issues, a precise infrastructure inventory is useful for long-term performance planning.
2. Better alerts and monitoring
When security concerns arise, a robust security model’s features, like SIEM (Types of SIEM Tools) , security orchestration, automation, and network detection and response, employ a mix of log and event analysis to identify them and then offer recommendations for how to fix them. This enables security operations center administrators to notice and respond to cybersecurity attacks more quickly.
3. Easier security policy creation
Modern security models ease the development of security policies since they allow for the creation of a single, universal policy that can be applied throughout the organization end to end. SSO is an excellent example of this, as it controls authentication for all network resources. The possibility for security vulnerabilities or gaps in some sections of the infrastructure also becomes much less likely, making the deployment and administration of security policies from the administrator’s perspective straightforward.
4. Flexibility when transferring applications, data, and services
The requirements for the technology needed to support business shift along with the business objectives. As a result, applications, data, and information technology services are frequently relocated inside the corporate infrastructure. A modern security model is advantageous in this regard as it creates a central rule system for the management of app and data security. It also necessitates the use of automation tools to move these security and micro-segmentation policies to the necessary locations.
Final Thoughts
The contemporary labor force is progressively growing more mobile, utilizing various devices to access cloud services and applications beyond the confines of the company. Many businesses used to use the “verify, then trust” approach, which let users to access whatever website, app, or gadget they wanted as long as they had the right login information.
Due to the dissolution of the once-reliable corporate zone of control and the resulting elevated risk of exposure, numerous firms became vulnerable to ransomware, malware, and data breaches. Particular digital infrastructures that house users, devices, data, and applications increasingly require protection.
