Prime Security has secured a $20 million Series A funding round led by Scale Venture Partners, with participation from Foundation Capital, Flybridge Ventures, and Ofir Ehrlich, the Chief Executive Officer and Founder of Eon. The investment will support the company’s go-to-market expansion and accelerate the development of its Agentic Product Security Platform, which comprises autonomous artificial intelligence agents that continuously monitor, assess, and guide product security throughout the development lifecycle.
The company is focused on redefining how product security is integrated into software development by moving protection efforts into the design phase rather than into post-development testing. Prime Security highlights that modern engineering teams operate at a pace that limits the reach of traditional manual reviews. As organizations adopt artificial intelligence-assisted coding, the gap between development velocity and security capacity continues to widen.
Prime Security’s flagship product, the Agentic Security Architect, automates security design reviews and identifies flaws across planned development work. By embedding directly into engineering workflows, the platform provides broader visibility into design-level risks and enables teams to cover nearly all development tasks rather than only a small portion.
The company reports that customers using the system have achieved significantly faster resolution of design-stage issues, a complete assessment of planned work, and reduced time and cost associated with security reviews, compared to the small fraction previously reviewed manually.
Founded in 2023 and headquartered in New York with offices in Tel Aviv, Prime Security integrates with widely used engineering tools to help organizations detect, prioritize, and mitigate design-level risks. The company is SOC2 Type II certified and works with customers including PayPal, Qualtrics, Bumble, ThoughtSpot, and Redis Labs. Prime Security also won the Black Hat 2025 Startup Spotlight as it began commercializing its technology.
The new funding positions Prime Security to expand its capabilities as engineering teams increasingly look for automated systems that scale with development activity rather than slow it down.
KEY QUOTES:
“Integrating security into the design phase has always been a technically challenging manual process. Prime’s unique approach transforms this critical, time consuming stage. 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.”
Ariel Tseitlin, Partner at Scale Venture Partners
“Modern product development is changing in front of our eyes. 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.”
Michael Nov, Co-Founder and Chief Executive Officer of Prime Security
“At PayPal, we know that security must evolve as fast as the threat landscape. 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. This capability helps us move with speed and confidence to deliver for our customers and strengthen trust in our business globally.”
Shaun Khalfan, Chief Information Security Officer at PayPal
