Prime Security Platform is an AI-driven product security solution that automates security design reviews and risk analysis during the development lifecycle. The platform integrates with development tools to initiate security reviews from multiple sources including ad-hoc requests, engineering flags, and automated risk scans. The platform collects technical, business, and environmental context for each review and builds a Security Context Graph that serves as a living blueprint of resources, controls, and risks. This graph functions as persistent memory that improves the accuracy of subsequent reviews. Prime analyzes risks by understanding affected resources, likelihood, and impact, then prioritizes critical issues. It maps identified risks to real-world attack patterns using environmental context and known threat behaviors to show potential exploitation paths. The platform generates actionable mitigation plans based on best practices, internal policies, and past resolutions. These recommendations are delivered directly into developer workflows through native integrations with planning and development tools. Prime supports multiple use cases including discovering design risks across developer tasks, automating security and privacy reviews, providing real-time security consultation, and safeguarding AI-generated code with security context.
