Secure your AI development cycle from start to finish

Prime Security is an agentic product security platform that secures the AI development cycle from design to deployment.

Prime agents work inside the development environment, mapping every application, policy, resource and data flow. They review specs and architecture before code is written, check every pull request — whether a developer or an AI agent wrote it — and embed security policies directly into AI coding tools such as Claude Code and Cursor.

After the code ships, Prime identifies vulnerable packages that attackers can actually reach and runs continuous white-box pentesting across source, architecture and controls. Fixes are delivered where the work happens: in the pull request, Slack or Jira for developers, and over MCP for coding agents. Prime is built for product security engineers and security architects who need to keep pace with AI-driven development.

Prime Security raised a $20 million Series A in October 2025 led by Scale Venture Partners, and won the Startup Spotlight Competition at Black Hat USA 2025.
