Prime Security recently announced its $20M Series A funding, which will fuel Prime’s go-to-market expansion and accelerate development of its Agentic Product Security Platform.

The round was led by Scale Venture Partners, with participation from Foundation Capital, Flybridge Ventures, and Ofir Ehrlich, CEO & Founder of Eon.

The Agentic Product Security Platform is a growing suite of autonomous AI agents that continuously monitor, assess, and guide product security throughout the entire development lifecycle.

Modern development runs at machine speed, but security still operates like an assembly line, slow, manual, and dependent on scarce expertise.

Today, security teams have the capacity to manually review only a small fraction of planned work before release, leaving the rest to chance.

As AI-assisted coding accelerates development velocity, this gap keeps widening. Prime’s agentic platform automates this manual craftsmanship, transforming design-stage protection into a continuous, intelligent process that scales with engineering.

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

“Having led technical, GTM, and security teams at companies like PayPal and Own, and scaled enterprise Product Security programs, they’ve experienced firsthand the problem they’re solving.

“This combination of category-creation vision and deep operational expertise is what defines market leaders.”

“Modern product development is changing in front of our eyes,” added Michael Nov, Co-Founder and CEO of Prime Security. “We founded Prime to redefine how security fits into this new world, with agentic systems that operate starting at the design phase, not after development.

“Our mission is to build security that scales with engineering instead of slowing it down.”
