SAN FRANCISCO — (BUSINESS WIRE) — Horizon3 AI, a leading provider of autonomous security solutions, today announced $40M in Series C funding led by Craft Ventures with participation from Signal Fire.

With 3 times customer growth year over year, Horizon3’s NodeZero platform has quickly become a leading industry tool for autonomous pentesting, helping customers quickly verify their security posture and reduce their exploitable attack surface.

This funding will be used to build out Horizon3’s enterprise-wide, proactive security platform, expand channel and partner presence and meet the growing demand of customers worldwide. Founded in late 2019, Horizon3 AI has raised a total of $78.5M to date.

The demand for NodeZero continues to skyrocket: Autonomous penetration testing was recently added as a new category to the U.S. Department of Defense Tech Watchlist. Customers using NodeZero today span 50 industries and 25 countries, including manufacturing, health care, financial services, education and local government.

With this new funding, Horizon3.ai will integrate pentesting, SOAR, and detection engineering into a security platform that enables customers to proactively secure their enterprise.

“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. “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.”
