About This Architecture

Zero Trust Architecture - Full Stack implements continuous identity verification, device posture checks, and micro-segmentation across all network tiers. Identity providers, MFA/SSO, and PKI certificates authenticate users and devices, feeding a Policy Engine that evaluates risk scores and context before granting least-privilege access through secure gateways. Application tiers—Web, API, Cache, and Database—are isolated by segment firewalls enforcing attribute-based access control and mTLS encryption. Continuous monitoring via SIEM, UEBA, and threat intelligence detects anomalies and enforces real-time policy adjustments. Fork this diagram to customize policies, add your IdP integrations, or document your organization's zero-trust rollout.

How do I design a zero-trust architecture that verifies identity and device posture before granting access to micro-segmented application tiers?

This diagram shows a complete zero-trust stack: Identity Providers and MFA/PKI authenticate users and devices; a Policy Engine evaluates risk scores and context via a Policy Decision Point; Secure Access Gateways enforce least-privilege access through WAF, API Gateway, and Reverse Proxy with mTLS; and micro-segmented tiers (Web, API, Cache, Database) are isolated by segment firewalls.
