The Firewall for
Agentic AI.
Protect agents with system-level access from indirect prompt injections, jailbreaks, and unauthorized commands. Deterministic threat blocking in under 1 millisecond, at every tool call.
- Decodes Base64 & obfuscated payloads
- Real-time Shannon Entropy analysis
- Zero-day instruction override detection
BUILT FOR THE AGENT STACK YOU ALREADY SHIP
From raw chaos
to a controlled shape.
Every unfiltered instruction that reaches your agent is unpredictable — jagged, high-entropy, shaped by whoever wrote it. AgentGuard's engine reduces that chaos to a single verdict in under a millisecond, every time.
Scroll and watch it happen: the same geometry that represents an unscanned payload settles into the hexagon we use everywhere in the product to mean verified safe.
Three steps, sub-millisecond.
Every payload runs the same deterministic sequence before it ever reaches your agent's tools.
Decode
Base64, leetspeak, and nested encodings are unwrapped so hidden instructions can't slip past a surface-level scan.
Analyze
Shannon entropy and zero-day heuristics score the payload for randomness, intent, and structural anomalies.
Block or Pass
A deterministic verdict is returned with the matched flag and engine latency, before your agent acts.
One engine, every attack surface.
Obfuscation decoding
Catches Base64, leetspeak, and layered encodings before they reach your model.
Entropy analysis
Flags abnormally random strings that look like disguised commands or exfil attempts.
Zero-day heuristics
Detects override patterns without relying on a static, easily-bypassed keyword list.
Deterministic verdicts
The same input always returns the same decision — no silent drift between runs.
Sub-millisecond latency
Scans run inline with tool calls without adding noticeable delay to your agent.
