Detect
11-layer scanner pipeline. 48 DLP patterns. A2A scanning. Encoded payload handling across HTTP, WebSocket, and MCP.
Enforce
OR-composed kill switch. Adaptive escalation. Process sandbox on Linux and macOS. MCP tool policy with redirect. Fail-closed on every path.
Prove
Evidence for every machine operation. Hash-chained flight recorder. Ed25519-signed assessment reports. 24+ attack simulations.
Capabilities
What Pipelock covers
A compressed view. The full inventory lives on the product page.
Data Loss Prevention
48 credential patterns with checksum validation. Base64, hex, URL, and Unicode encoding-aware.
Prompt Injection
25 detection patterns. 6-pass normalization covering zero-width chars, homoglyphs, and leetspeak.
MCP Security
Tool poisoning detection, rug-pull tracking, policy engine with redirect, session binding, and chain detection.
Process Sandbox
Landlock + seccomp + network namespaces on Linux. sandbox-exec on macOS. Per-agent profiles with strict mode.
Adaptive Enforcement
Per-session threat scoring. Three escalation levels. Auto-recovery after clean traffic. No permanent lockouts.
Compliance Evidence

Three real artifacts the binary produces today. Click any panel to see how it works in production.

01 Monitor
Live fleet dashboard
70 Prometheus metrics across the fleet. Threat score, kill state, scan latency, blocked verdict counts.

02 Block
4-source kill switch
Trigger from CLI, dashboard, API, or Telegram. One source flips the agent into deny-all in under a second.
