Agent Baseline is an open, versioned security resource for enterprise AI agents. It defines six security outcomes—Discover, Constrain, Authorize, Observe, Validate, and Respond—and 35 controls covering agent inventory and dependencies, scoped capabilities, identity and authority, correlated evidence, pre-use and ongoing validation, and revocation or quarantine. The project provides a white paper, source materials, implementation requirements, and evidence criteria for each control. It is maintained through open community review, issues, and implementation feedback, and serves as the baseline for the separate Secure Software Factory reference architecture.

deepsec is an open-source, agent-powered vulnerability scanner and security harness from Vercel Labs for on-demand review of large codebases within the user's own infrastructure. It identifies candidate vulnerabilities, uses AI models to investigate them, supports triage and optional revalidation to reduce false positives, and can run work across parallel worker machines. The CLI initializes a repository with `npx deepsec init`, stores state and findings in a `.deepsec/` directory, and resumes interrupted runs while skipping files already analyzed. Subsequent commands separate fast pattern scanning from AI processing and revalidation, and findings can be exported as Markdown directories or JSON. Model access can use Vercel AI Gateway, direct OpenAI or Anthropic credentials, or a custom HTTPS provider; scan cost and duration can be capped with command-line options.

Baseten is an inference platform and company that provides tools to deploy, serve, and scale open-source and custom AI models in production. It offers managed infrastructure and tooling for model hosting, APIs, and inference at scale.
