About

Prime Security is a cybersecurity SaaS platform that embeds an AI-powered security architect into the software development lifecycle at the design stage — before code is written. Its core product, Prime, ingests product and engineering tickets along with associated design artifacts, automatically performs threat modeling and security design reviews, and delivers structured risk findings and mitigations to security and engineering teams. Key capabilities include design-stage risk visibility and posture management, automated security and privacy design reviews, and secure architecture guidance for AI-generated code. Prime integrates with Slack and developer workflows so security reviews happen in hours rather than weeks, enabling small security teams to achieve full coverage across all new product features. The company is headquartered in Tel Aviv and New York City, raised a $20M Series A led by Scale Venture Partners, and counts SmartBear, BigID, Redis, PayPal, Oscar Health, MX, and ThoughtSpot among its customers.
