SENTRY AI · Enforce

See unsafe AI activity. Enforce policy before data leaves.

SENTRY AI is Armorstack’s AI-specific security enforcement layer. It answers one question: what AI activity is unsafe, and what should we stop, constrain, redact, block, or escalate? Shadow AI — the AI-era equivalent of shadow IT — is one of the strongest cases for it: a passive collector watches for AI-tool usage across your fleet, seals findings into a tamper-evident ledger, and enforces where visibility alone isn’t enough.

Three Layers, Not One

Correlate. Prove. Then Enforce.

SENTRY Pulse correlates the general threat surface in real time. Miralto, Armorstack’s own governance and evidence platform, is scoped deliberately to observe, understand, and prove — guidance and control truth, never enforcement. SENTRY AI is built with a different charter: it’s the enforcement layer, specific to AI activity. Where Pulse tells you what’s happening and Miralto tells you what’s provable, SENTRY AI acts on unsafe AI activity right now.

A passive collector — Windows and Linux, no inbound ports required — watches for connections to AI-vendor domains and AI-API-key-shaped environment variables across the fleet. Every finding is sealed into a tamper-evident, hash-chained ledger and mapped to NIST AI RMF controls, surfaced on a dashboard as a governance-gap heatmap with an exportable vendor-egress report.

Shipped, Not Roadmap

Six Capabilities, Live and Verified

An August 2026 build closed six capability gaps against a named competitor, Forcepoint — all shipped, merged to production, and independently re-verified line by line, not taken on a self-report. Sold and delivered as a managed Sentry offering, not a self-serve signup product.

Agent Data-Flow Visibility

Logs what an AI agent actually touched — not just whether its own claim of success passed.

Content-Block & Content-Redact Enforcement

Real-time DLP actions that auto-fire in production, opening an Arkon ticket on every finding — no human override, by design.

Cloud DSPM

Scans AWS S3 for exposed PII, credentials, financial, and health data. Observability-only — it flags, it doesn’t act.

Network-Level Shadow-AI Detection

Catches AI-tool usage via DNS and firewall logs — works even with no endpoint agent installed on the device.

UEBA Behavioral Risk Scoring

Flags sustained high-risk user behavior across identity-aware connectors — patterns, not single events.

Browser-Extension Capture Point

Prototype

Blocks risky ChatGPT, Claude, and Gemini submissions at the browser. Still prototype-stage — not yet delivered as a shipped feature.

What the Export Actually Is

The exportable report is vendor-egress telemetry — a record of what connected to which AI vendor, when, and from where. It is not a true AI Bill of Materials, and we don’t call it one.

Content-block and content-redact enforcement has no human override. That’s a deliberate design decision, not a limitation we’re working around — a finding that can be waved through by whoever’s on shift isn’t enforcement.
