Enterprise security startup Prime Security today revealed that it has raised $20 million in an early-stage funding to fuel its go-to-market expansion and accelerate development of its Agentic Product Security Platform.

Founded in 2023, Prime Security is on a mission to overhaul how software development teams handle security by making security part of the design process rather than a gate at the end.

Prime’s Agentic Product Security Platform is built around what the company calls an Agentic Security Architect. The platform uses autonomous artificial intelligence agents to continuously monitor, assess and guide product security throughout the entire development lifecycle, starting at the design stage before any code is written.

The system replaces slow, manual security reviews by embedding security reviews into engineering workflows with automated, scalable assessments. The assessments help organizations move faster while still ensuring security is baked into new features and design plans.

Prime started to commercialize its product earlier this year. It now counts among its customers PayPal Holdings Inc., Qualtrics International Inc., Bumble Inc., ThoughtSpot Inc. and Redis Ltd., with development teams of more than 200 engineers who are seeing significant impact. The company claims that its customers are achieving nearly 100% coverage of planned work versus the 10% to 15% typical with manual reviews, are resolving design-stage risks up to 30 times faster, and are cutting the time and cost of security reviews by half.

“Prime Security’s autonomous, design-stage reviews give us continuous and adaptive visibility across our engineering ecosystem, enabling us to identify and address risks earlier in the software development lifecycle,” said Shaun Khalfan, chief information security officer at PayPal. “This capability helps us move with speed and confidence to deliver for our customers and strengthen trust in our business globally.”

The company says that by providing continuous, automated security assessment of all planned work, it empowers security teams to focus on strategic architecture while ensuring comprehensive coverage of every feature, enhancement and change flowing through the development pipeline.

The Series A round was led by Scale Venture Partners LP, with Foundation Capital, Flybridge Capital Partners and Ofir Ehrlich, founder and chief executive of E.ON SE, also participating.

“Integrating security into the design phase has always been a technically challenging manual process,” said Ariel Tseitlin, partner at Scale Venture Partners. “Prime’s unique approach transforms this critical, time-consuming stage.”

Prime Security had previously raised seed funding of $6 million in October 2024.
