Deterministic Security Gate

Stop Threats Before They Emerge

Sentinel is a deterministic policy enforcement engine that creates an impenetrable development perimeter. It blocks insecure code before it reaches your repositories or production environments.

Security Gate: ACTIVE

$ git push origin main

Sentinel is a deterministic security enforcement engine designed for use in controlled CI/CD environments. Due to its gatekeeping nature and impact on delivery pipelines, Sentinel is distributed exclusively under individual professional or enterprise licensing agreements.

Deterministic by Design

Unlike scanners that provide risk opinions, Sentinel delivers authoritative decisions. Every execution results in exactly one of two states.

ALLOW (0)

Zero violations detected. Code meets all security policies. Pipeline proceeds without interruption.

Pipeline Proceeds

BLOCK (1)

Unapproved critical violations detected. Pipeline terminates immediately. Code cannot proceed.

Pipeline Terminated

WARN (Audited)

Overridden violations with formal justification. Pipeline proceeds with explicit audit trail.

Audited Exception

Audit-First Exception Model

Sentinel uses an auditable exception model. Violations cannot be silently ignored; they must be formally justified in sentinel.yaml.

# sentinel.yaml - Policy Overrides
overrides:
- rule_id: "SUPPLY-001"
justification: "Legacy base image required for test-suite compatibility"
- rule_id: "SEC-001"
justification: "Verified public mock token for internal tests"

How Sentinel Works

Sentinel enforces a single authoritative decision point per execution.

Built-in Security Rules

Docker Integrity
SUPPLY-001

Prohibits mutable :latest tags. Enforces pinned versions for build reproducibility.

Hardcoded Secrets
SEC-001

Blocks AWS keys, private keys, bot tokens, and other credentials in code.

GitHub Actions Pinning
CICD-001

Enforces SHA pinning for GitHub Actions to prevent supply chain attacks.

Kubernetes Security
INFRA-001

Enforces runAsNonRoot and resource limits in K8s manifests.

Zero-Leakage & Offline Guarantee

Sentinel forbids all network access at runtime by design. Safe for air-gapped environments.

No Telemetry

No usage data is ever collected. Sentinel operates without phoning home.

Air-Gap Ready

Operates without internet access. Safe for highly restricted internal environments.

Immutable Logic

Never self-updates or pulls remote rules at runtime. Security logic is guaranteed.

Ready to Secure Your Perimeter?

Stop threats before they emerge. Sentinel creates an impenetrable development perimeter that blocks insecure code at the commit level.

Sentinel is designed for private-mirror environments. Admins host the core in a corporate repository, ensuring full sovereignty over security logic.
