Zero Trust Security Model

Overview

The Zero Trust Security Model is a modern approach to cybersecurity based on the idea that no user, system, or application — whether inside or outside the network — should be inherently trusted. Every access request must be verified and authorized in real time, aligning with the needs of distributed, cloud-native architectures and the rising presence of non-human identities.

What Is the Zero Trust Security Model?

Zero Trust eliminates the traditional perimeter-based security mindset. Instead of assuming anything inside the network is safe, it requires strict authentication, granular access controls, and continuous monitoring. This model is especially important as organizations rely more heavily on machine credentials, OAuth tokens, and automated workflows to operate critical systems.

How Does the Zero Trust Model Work?

Zero Trust relies on several key principles:

• Least privilege enforcement: Every identity — human or non-human — is granted only the access it truly needs.
• Microsegmentation: Access is restricted not just at the network edge but between individual systems and services.
• Continuous validation: Trust is not permanent. It is re-evaluated based on behavior, risk posture, and context.
• Lifecycle governance: Every identity’s access is governed from creation to revocation, a key tenet of lifecycle management.

These practices help stop lateral movement and unauthorized access, especially by attackers exploiting shadow tools or orphaned credentials.

Why Is Zero Trust Important?

Today’s environments include SaaS platforms, multi-cloud workloads, and a growing number of service accounts. In this landscape, assuming trust can result in breach propagation. Zero Trust ensures that every access is deliberate, justifiable, and governed.

Zero Trust is especially effective when applied to non-human access, where over-permissioned automation and stale credentials often go unchecked. Astrix strengthens this foundation by delivering visibility, enforcement, and remediation.

Astrix’s Approach to Zero Trust Security

Astrix Security brings Zero Trust to life by enabling organizations to:

• Discover non-human identities
• Reduce the non-human attack surface
• Automate identity and permission clean-up with NHI remediation
• Detect and respond to suspicious non-human activity

Together, these capabilities deliver the continuous verification, least-privilege enforcement, and automated governance at the heart of Zero Trust.

Zero Trust isn’t just a concept — it’s a commitment to securing every access path. Schedule a live demo to see how Astrix enables Zero Trust for your non-human ecosystem.
