What happened
On Oct 8 Tenable expanded the CyberAgents Exchange with Exchange Inspector, a three-stage vetting of community AI components: Tenable One AI Exposure skills inspection (prompt-injection, hardcoded secrets), an OpenAI GPT cyber-model assessment, then Tenable researcher runtime verification, testing 15 issue classes across three stack layers. First three vetted skills (SOC Hunter, Remediation Priority & Impact Agent, Splunk Cloud Security Skill) shipped as part of Tenable's OpenAI Daybreak Defense Network participation.
Why it matters
This is the first major output of the OpenAI Daybreak Defense Network and starts to give the open-source agent marketplace (agents/skills/MCP servers carrying credentials) a trust layer analogous to software supply-chain vetting — answering the 'what will this agent do before I deploy it' question in a vendor-agnostic directory.
Applicability
Security teams consuming open-source agents/skills/MCP servers should check for Inspector-vetted listings before production deployment; vendors should watch this as a template for AI-component supply-chain assurance.
