JetStream Security-First AI Governance Platform
Enterprise security teams deploying agentic AI in production need JetStream Security-First AI Governance Platform to stop treating AI systems as black boxes and enforce least-privilege access across agent hand-offs, the real attack surface most teams ignore. The platform's continuous discovery and Blueprint-based runtime enforcement directly addresses NIST CSF 2.0 Identity Management and Continuous Monitoring, catching AI drift that static policy frameworks miss. Skip this if your organization is still in proof-of-concept phase or lacks the operational maturity to version and audit AI workflows; JetStream assumes you're ready to govern agents the way you govern service accounts.
Security teams deploying Claude or other agentic AI systems will find real value in MCPX's per-agent tool restrictions and immutable audit logs that actually capture prompt payloads and attribution, not just API calls. The role-based access control with on-behalf-of tracking addresses the specific governance gap that makes AI agents harder to audit than traditional service accounts. This tool prioritizes Govern and Detect over Respond, which works if your security model treats agent behavior as inherently less trustworthy than human access. Skip MCPX if you're looking for a lightweight proxy; the MCP Risk Score Engine is beta and Lunar.dev's 15-person team means you're betting on a startup's ability to track an evolving threat surface faster than vendors with security divisions.
