Defense Against The Dark Arts

A firewall and antivirus for autonomous agents. D.A.T.D.A scans every prompt, tool call, memory write and inter-agent message โ€” and blocks prompt injection and the other dark arts before they execute.

Live threat feed ยท fleet-wide verdicts (redacted)

Three ways to protect an agent

Integrate in five minutes. Cheapest-integration first.

๐Ÿ”Œ

REST API

POST /v1/scan with the text or tool call. Get a verdict โ€” allow, flag, or block โ€” in one round trip.

๐Ÿงฉ

MCP server

Add one endpoint. Your agent gains scan and check_tool tools in Claude, Cursor, or any MCP host.

๐Ÿค–

Agent-native

Autonomous agents discover, self-provision, and buy scan credits within a spend cap โ€” no human in the loop.

Coverage across every channel

Mapped to OWASP Agentic Security (ASI01โ€“10) and NIST AI 100-2.

The moat ยท Causal Threat Graph

Detection that learns from every attack, and remembers every agent

The signatures are table stakes. The differentiation is a real-time, streaming causal knowledge graph of attacks โ€” running in our private core, reached only through the API.

  • โ—†
    Network-effect intel. Every verdict across the fleet becomes a causal event. Emerging campaigns surface as hot fronts and auto-promote to live signatures โ€” defenses you inherit from attacks you never saw.
  • โ—†
    Stateful per-agent tracking. The graph holds each agent’s causal chain, so multi-step drift that looks benign scan-by-scan is caught on the trajectory.
  • โ—†
    Instant drift detection. Out-of-norm behaviour is flagged the moment an action diverges from the agent’s stated intent.
