The surge in venture capital bets on startups in the nascent attack surface management business continued apace Wednesday with Israeli risk management firm CyCognito announcing a new $100 million funding round.
CyCognito, which maintains headquarters in Tel Aviv and offices in Silicon Valley, has raised a total of $153 million since launching three years ago with a platform to help businesses manage attack surfaces on a continuous basis.
The new $100 million Series C round was led by the Westly Group and included money from new investors Thomvest Ventures and The Heritage Group. The company said its earliest backers — Accel, Lightspeed Venture Partners, Sorenson Ventures and UpWest — also joined the round.
CyCognito sells a platform that let’s security teams identify attack surfaces, discover attack vectors, monitor risks associated with subsidiaries, and validate an organization’s security posture.

The company’s automated platform scours the Internet to collect data and combines it with machine learning to map Internet-exposed assets, determine their business context and detect attack vectors.
CyCognito said it has found success with the platform among large enterprises, noting that Fortune 500 companies like Colgate-Palmolive, Tesco and Scientific Games Corporation are among customers getting full visibility and context into risk to preempt potential attacks
The company says defenders can use its technology to autonomously build a graph data model that represents an organization’s business structure — from company name, to departments, subsidiaries, acquisitions and brands an organization owns. The platform then scans billions of servers and devices across the Internet to contextualize and identify internet-exposed and unmanaged assets that could serve as entry points for attackers.
