About Prime Security

Prime Security sells an AI security review platform designed for software development lifecycles. Prime Agents learn an organisation's architecture, code and risk history. Prime Security describes one platform covering the SDLC before the code, in the code and after the code. Prime agents work autonomously inside the customer environment, mapping every application, policy, resource and data flow. Prime agents live inside the development lifecycle and understand designs, code, cloud and policies.[1][2][3][4]

Prime Security says AI agents, multiple stacks and complex development processes have created an attack surface that no existing security tool was built to handle. Prime Security states its aim as connecting architecture, code and cloud to find every exploitable attack vector before attackers do. Prime tracks every asset as it moves from design to deployment. Prime learns an organisation's architecture, past decisions and risk profile, and each review builds on the last one.[3][4][5]

Autonomous design reviews use AI agents to review specs, architecture and data flows to uncover security risks before code is written. Prime checks every design, scores every risk and validates every fix in code. Prime can produce a threat model, and Prime combines design-level analysis with actual code. Prime Security covers architecture reviews, threat modeling, documentation analysis, and security analysis tied to tickets and code changes. Prime finds vulnerabilities and logic flaws in AI-generated and human-written code. Prime checks every PR the moment it opens, whether a developer or an agent wrote it. Prime checks each pull request for approved auth flows, encryption methods, architecture patterns and framework requirements. Prime reviews every PR against the policies that apply to that repo, validates each finding and hands the agent the context to fix it. Prime logs every review, finding, validation and fix.[1][2][3][4][6]

Prime sets security guardrails for agents like Cursor and Claude Code, catching insecure code at the PR before it merges. Prime Security embeds security policies directly into AI coding workflows. Prime inventories every package in the dependency graph, direct and transitive, and matches it against known CVEs and the license policy. Prime identifies vulnerable packages accessible to attackers with proven attack paths. Exploitable findings arrive with the full attack path, and unreachable ones arrive marked as noise, with the reasoning attached. Prime checks every dependency against the license policy in the same scan. Prime runs continuous attack path analysis with source, architecture and controls. Prime maps how services talk, where data flows and how an attacker would chain it all together. Prime evaluates multi-step attacks the way an attacker plans them.[1][3][4][7]

Prime delivers a tailored fix wherever the work happens, with the PR, Slack or a Jira ticket for developers. For dev agents, Prime delivers context over MCP, so mitigation runs with no human in the loop. Prime proposes mitigations built for the codebase, delivers them to developers and agents and validates the fix landed in code. Agents run continuously across planning and development workflows without requiring custom engineering from the customer team. Prime integrates with Github, Gitlab, Claude Code, Cursor, Jira, Confluence, Google Drive, Azure DevOps, Linear, and Git Issues.[2][3][4]
