Zero Trust Architecture

What it is

Zero trust replaces the old "trusted internal network, untrusted external network" model with "never trust, always verify" — every request is authenticated, authorized, and encrypted regardless of where it originates.

Key points

• Core principle: no implicit trust based on network location — a request from inside the corporate network gets the same scrutiny as one from the public internet.
• Microsegmentation: instead of one flat internal network, resources are isolated so that compromising one doesn't grant access to everything.
• Continuous verification: identity and device posture are checked per-request, not just once at login.
• Zero trust is an architectural philosophy implemented via existing controls (strong IAM, microsegmentation, device attestation) — not a single product.
