Threat Intelligence Query

Query real-time threat data across maritime, cyber, and infrastructure domains

Incident Management

Create, track, and resolve security incidents with AI-assisted triage

Vessel Tracking

Track vessel positions, detect anomalies in AIS data, and profile vessel behavior

Report Generation

agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Version: 1.0.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
