Ensuring network and cloud security has become one of the topmost priorities for global enterprises and organisations.

Several security solutions can be used to protect the network’s data and resources from malicious attacks, including Virtual Private Networks (VPNs). However, VPNs impede several security risks, latency, and performance issues, compromising your network security and hampering scalability.

Thus, when it comes to cybersecurity, the Zero Trust Security architecture has become quite a buzzword amongst enterprises.

In this article, we’ll get into understanding what Zero Trust is, Zero Trust architecture, and its key components.

What Is a Zero Trust Architecture?

Zero Trust is a cybersecurity approach rooted in the core principle of ‘’Never Trust, Always Verify.’’

Thus, it removes the excessive implicit trust you find in VPNs to protect modern environments with solutions, such as strong authentication and authorisation, network segmentation, granular access control, least privilege policies, and threat prevention.

Zero Trust architecture, as the name suggests, is a blueprint or architecture for implementing Zero Trust principles to achieve network security goals and prevent online threats.

Hence, the Zero Trust Architecture model replaces the traditional network security model. Traditional security solutions employ implicit trust, allowing every user and device to access the network and its critical resources.

Unfortunately, this implicit trust makes it easier for malicious users and breaches to move laterally within the network to exploit resources and data for malicious purposes.

Thus, the Zero Trust Network architecture secures the network effectively and provides several benefits, including:

  • Strict authentication and authorisation
  • Granular visibility over user activity and behaviour
  • Improved network monitoring, making it easier to identify threat vectors
  • Seamless scalability
  • Decreased attack surface and reduced cybersecurity risks

That being said, let’s look at the key components of a Zero Trust architecture.

Key Components of Zero Trust Architecture

To implement the Zero Trust principles, organisations are increasingly looking for ways to eliminate uncertainties and enforce security and access policies.

Here are the three major components of the Zero Trust Application Security architecture:

  • Granting access: It includes the factors you must consider in granting and allowing access. Thus, the policy engine’s first component is to grant, deny, or revoke specific user access to the requested company network resources.
  • Controlling access: The second component includes determining the level of access or how much access a user should be granted. Thus, it comprises a Policy Enforcement Point (PEP) to enable, terminate, or monitor connections between the users or devices and the network resources.
  • Continuous monitoring: The third component of the Zero Trust Application Access architecture allows enterprises to determine ways to monitor changes in the network security posture. Thus, it includes a policy administrator that commands PEP based on the policy engine’s decisions to grant or deny connection to the user to a particular requested network resource.

Thus, deploying these key Zero Trust architecture components allow organisations to ensure network protection for a secure and robust network security posture.


According to Gartner’s report, 2023, around 60% of organisations will be using and adopting the Zero Trust architecture instead of VPNs.

With network segmentation, granular control, high performance, and strict authentication models, Zero Trust significantly strengthens corporate security and uplifts the enterprises’ security posture.
