New funding led by ClearSky Security will fuel engineering and sales momentum

BROOKLYN, NY, Aug. 08, 2018 (GLOBE NEWSWIRE) -- Capsule8, the pioneer behind the industry’s only zero-day attack detection platform purpose-built for production, today announced it has secured its $15M Series B round of funding. The round, led by ClearSky Security, also features participation from Bessemer Venture Partners, Rain Capital and strategic investors. The round brings total funding to $23.5M and will be used to scale Capsule8’s engineering organization and fuel sales efforts of the Capsule8 platform.

“We are incredibly impressed with the momentum of Capsule8 and the market traction they have already made since their product launch in April,” said ClearSky Security Managing Director Jay Leek. “We believe they are unique in how they are solving a very complicated issue, security in the production environment, and know they are set up for even more big wins in their next phase of growth.”

Capsule8 is the industry’s only real-time, zero-day attack detection platform capable of scaling to massive production deployments. Capsule8 delivers continuous security across the entire production environment — containerized, virtualized and bare metal. Capsule8 enables its customers to stop attacks in progress, and without human intervention. And it provides deep visibility into the system that makes it easy to investigate incidents in a way that is specifically designed to meet enterprise needs. Capsule8 is driving a new automated approach to attack detection and response that will, over time, help organizations arrive at the SOCless enterprise.

“Our early traction with some of the largest companies in the world, coupled with this latest round of funding, is incredible validation for our team and our technology,” said John Viega, CEO, Capsule8. “The landscape of enterprise production environments continues to change and enterprise security has to change along with it.
