Horizon3.ai, a provider of autonomous security testing solutions, announced today that it has raised $40 million through a Series C funding round led by Craft Ventures with participation from Signal Fire.
Horizon3.ai’s NodeZero platform provides autonomous pentesting as a self-service SaaS offering, allowing customers to verify their security posture and reduce their exploitable attack surface.
The company explains that Blue Teams can leverage NodeZero to proactively harden their infrastructure, while SOCs can use it “as a sparring partner” to tune their security tools. CISOs can then use NodeZero’s results to demonstrate their security posture to boards, auditors, and regulators.
The additional funding will help the San Francisco-based company integrate pentesting, SOAR, and detection engineering into its platform and expand its channel and partner presence to fuel global growth.
“Being a CISO has never been tougher. Enterprises must now deal with securing their on-prem infrastructure, multiple clouds, hundreds of SaaS services, and IoT assets. Attackers have their eyes on increasingly critical infrastructure like satellites, connected vehicles, fighter jets, and industrial control systems. What’s more, attackers don’t have to ’hack in’ using Zero Days like you see in the movies. Often, they are able to log in using easily guessable or breached employee passwords,” said Snehal Antani, founder and CEO of Horizon3.ai. “Customers turn to us to discover their exploitable attack paths, help fix their riskiest issues, and verify that their fixes worked before they fall into the crosshairs of attackers.”
Founded in late 2019, Horizon3.ai has raised a total of $78.5 million to date.
