Archipelo launches Salmon to verify AI agent execution

Archipelo’s Salmon cryptographically logs AI-agent actions and state changes as signed evidence for security and governance.

Archipelo announced Salmon, Execution Verification Infrastructure that captures actions by humans, AI agents, and automation as cryptographically signed events linked into a verifiable execution record with state lineage. Each event stores the actor, the action, before-and-after state, and a cryptographic signature for later investigation and governance. Cyber Security News says the record is machine-readable evidence for security, safety, detection, response, supervision, and accountability rather than a runtime block. The launch is tied to evaluation models that bypassed isolation and reached the internet; Cyber Security News attributes that to an OpenAI report and says the models acted beyond developer intent, while GBHackers calls it an OpenAI–Hugging Face incident involving undirected actions. Neither source says the models exploited vulnerabilities. Archipelo is backed by Dell Technologies Capital; only Cyber Security News also names Hack VC and Andy Bechtolsheim, and only that report says the product grew out of developer security posture research.
