Zero Trust Architecture
Never trust, always verify—continuous authentication and authorization
Overview
Zero Trust is a security framework that eliminates implicit trust and requires continuous verification of every user, device, and connection—'never trust, always verify.' Instead of a network perimeter, Zero Trust enforces identity-centric security with least privilege access, micro-segmentation, and continuous validation. Executive Order 14028 man...
Key Capabilities
- Continuous identity verification with risk-adaptive authentication
- Device trust assessment and endpoint posture validation
- Micro-segmentation and software-defined perimeter (SDP)
- Context-aware access policies (user, device, location, data sensitivity)
- Encrypted communications (mTLS, TLS 1.3)
- Just-in-time (JIT) and just-enough access (JEA)
Key Benefits
- 50% reduction in breach impact (IBM Cost of Breach Report)
- 66% lower breach costs for mature Zero Trust organizations
- 45% faster breach containment and response
- Eliminates VPN vulnerabilities and lateral movement

Okta💡 Why It Matters
The perimeter is dead. Remote work (75% of workforce), cloud adoption (94% of enterprises), and mobile-first computing have dissolved the network boundary. VPN breaches increased 300% in 2024. Zero Trust provides security that works regardless of location, reducing breach impact by 50% according to IBM. Organizations with mature Zero Trust report 66% lower breach costs and 45% faster breach containment.
