MicroZAccess Architecture and Components

COSGrid ZTNA operates on the principle:

Never Trust. Always Verify. Continuously Validate.

Access flow logic:

  1. The user initiates the connection.

  2. Identity is verified.

  3. Device posture is validated.

  4. Policy engine evaluates contextual rules.

  5. Application-specific access is granted or denied.

  6. Continuous session monitoring is maintained.

All enforcement decisions are real-time and policy-driven.

Component Architecture



1. ZTNA Client (Endpoint Agent)

  • Installed on user endpoints.

  • Performs device posture checks.

  • Communicates with the policy controller.

  • Enforces local policies.

2. COSGrid Policy Controller

  • Central decision engine.

  • Evaluates identity + context + device posture.

  • Pushes enforcement rules dynamically.

3. Secure Application Gateway

  • Protects internal applications.

  • Enables application-layer access without exposing network.

4. Identity Integration Layer

  • Integrates with enterprise directory systems.

  • Supports SSO, MFA, and federation.

5. Logging & Analytics Engine

  • Real-time session visibility.

  • User activity tracking.

  • Compliance audit logs.

Workflow Integration

ZTNA integrates seamlessly into existing enterprise ecosystems:

  • Active Directory / LDAP

  • Cloud IdP (Azure AD, Okta, etc.)

  • SIEM platforms

  • Endpoint security tools

  • Firewall and SASE architecture

Integration ensures:

  • No infrastructure overhaul required.

  • Gradual migration from VPN.

  • Policy alignment across network layers.
