Zero-trust architecture
Deny by default. Leave owners, not a vendor.
Mission impact
Implicit trust is where breaches travel. Deny-by-default controls with named owners shrink what an attacker, a mis-scoped client, or an agent can reach.
Not a product
Implicit trust is a design choice. Zero trust is the counter-design. NIST SP 800-207 and the CISA Zero Trust Maturity Model are referenced models; no single tool achieves them. We implement controls with owners and a verification path.
What we put on the ground
Encrypted mesh with explicit grants, as code. Split DNS. Public ingress in its own segment. Layered authorization: network, identity-aware proxy, per-environment clients. Secrets encrypted before commit, under keys you hold. Continuous inventory instead of a one-time asset list.
Identity that can revoke
Customer-controlled OIDC. MFA. Group claims at the proxy. A staging client is useless against production. Retiring a client invalidates what it issued.
Agents are principals
An agent authenticates with its own OAuth identity. Server-side policy is the grant. Publish stays human. Delete stays denied. Sentinel enforces that policy at the system of record. Building agents is Agentic AI Development.

Key capabilities
Mesh and ACLs
No node talks to another without a reviewable rule.
Split DNS
Internal names do not resolve outside the boundary.
Ingress isolation
Only defined proxies face the public network.
Secrets under your keys
Encryption before commit. No third-party vault required.
Agent valve
Scoped credentials, field redaction, tamper-evident audit.
Sovereignty features
Identity is customer-controlled OIDC. Secrets are encrypted before commit under keys you hold. Mesh grants and DNS live as code in your repository.
Defense & government relevance
NIST SP 800-207 and the CISA Zero Trust Maturity Model are the referenced models. Controls are implemented with an owner and a verification path; we do not certify or authorize systems.
