Prime Security, founded in 2023 and headquartered in New York with an office in Tel Aviv, attacks a structural imbalance in modern software organizations: products and engineering teams keep growing, but application security teams do not. Prime's tagline captures the thesis — 'Your products keep growing. Your security team doesn't. Prime closes the gap.' The company builds agentic AI that scales product security by automating the reviews that human AppSec engineers can no longer keep up with.
Its flagship capability is the Agentic Security Architect, which autonomously conducts security design reviews. As teams ship new features and integrations, Prime's agents analyze architecture, code, and cloud infrastructure to surface design-stage risks and exploitable attack vectors before they reach production — shifting security left to the point where flaws are cheapest to fix. This addresses a notoriously manual, bottlenecked process that traditionally depends on scarce senior security architects.
Prime also provides AI-driven security code review that the company says reduces false positives by around 80%, along with real-time guidance for developers and guardrails for AI-assisted coding workflows. By embedding into tools engineers already use — Jira, Confluence, GitHub, and Azure DevOps — Prime aims to deliver near-complete coverage of development activity without slowing teams down, integrating security into the existing flow rather than bolting it on at the end.
The platform has gained early enterprise traction, with customers including PayPal, Qualtrics, Bumble, ThoughtSpot, Redis Labs, Oscar Health, and others. Prime won the Black Hat USA 2025 Startup Spotlight, holds SOC 2 Type II certification, and is available on the AWS Marketplace, signals aimed at building credibility with enterprise buyers.
In December 2025 Prime Security announced a $20 million Series A led by Scale Venture Partners, with participation from Foundation Capital, Flybridge Ventures, and Eon founder Ofir Ehrlich. Led by CEO Michael Nov and a founding team with security and go-to-market experience from companies like PayPal and Own, Prime is betting that agentic AI can finally let product security keep pace with the speed of modern, AI-accelerated software development.
