What is Zero Trust security & how does it work?

Zero Trust is a modern cybersecurity framework built on the principle of “Never Trust, Always Verify.” Unlike traditional perimeter-based security models, Zero Trust assumes that no user, device, application, or system should be automatically trusted — whether inside or outside the network.

Zero Trust continuously verifies identity, device posture, and access context before granting or maintaining access to critical systems and data.

Here’s how Zero Trust works:

• Identity Verification: Every user and machine identity is authenticated using strong methods like MFA and digital certificates.
• Device Validation: Devices are checked for compliance, health status, and risk posture.
• Least Privilege Access: Users receive only the minimum access required to perform their role.
• Continuous Monitoring: Sessions are continuously evaluated for anomalies or suspicious behavior.
• Policy Enforcement: Access decisions are dynamically enforced based on risk, context, and predefined policies.

At eMudhra, Zero Trust is enabled through SecurePass IAM, PKI-based authentication, MFA, PAM, and certificate-based device trust — ensuring secure access across cloud, on-premises, and hybrid environments.

Benefits of Zero Trust:

• Reduced attack surface
• Protection against insider threats
• Strong identity-based security
• Improved compliance readiness
• Secure remote and hybrid workforce enablement
