Horizon3 launches Adversarial Intelligence Frontier Lab built on NodeZero attack data

Autonomous penetration testing company Horizon3 AI Inc. today launched its new Adversarial Intelligence Frontier Lab.

The lab will draw on data from NodeZero, Horizon3’s penetration testing service, which is used by more than 7,000 organizations including banks, federal agencies and hospitals.

Purdue University’s Z. Berkay Celik has been named the lab’s inaugural director. Celik is an associate professor of computer science at Purdue and co-director of the Purdue Security Laboratory. Much of his work deals with finding software vulnerabilities and building defenses for autonomous systems, and he has run joint projects with industry and government.

According to Horizon3, NodeZero tests now produce about 30 billion tokens of anonymized data a day. Gathered on customers’ live production networks, the data also shows how their defensive tools reacted to each NodeZero command.

Snehal Antani, Horizon3’s co-founder and chief executive and a former chief technology officer of Splunk Inc., said the company has “spent years collecting” the data. Putting it to use in research like this is the next step, he said.

The lab’s first projects include research on coordinated groups of AI agents used in attacks. Deception is another, building on a Horizon3 paper titled “Honeyquest for LLMs.” Also on the list, according to Horizon3, are “interruption and rollback mechanisms” for autonomous security agents.

Horizon3 published a paper on keeping such agents under control in May. Using Anthropic PBC’s Claude Sonnet 4 and Claude Haiku 4.5 models, it tested a design that limited the AI to a fixed list of approved tools, and Horizon3 said the system never proposed an action outside that list across more than 420 deployments.

Trained separately for each customer, Horizon3’s cyber world models give its red and blue agents a shared memory, and the lab is expected to speed up their development. Horizon3’s Cyber Resilience Centers of Excellence, which focus on critical infrastructure, will also report to the lab.

Horizon3 said in October that it had passed $100 million in annual recurring revenue, with growth of 120% year over year. NodeZero has run more than 350,000 production-safe tests to date. Horizon3 said about 80% of its customers have moved from annual to monthly penetration testing.

Founded in 2019, Horizon3 raised $250 million in August at a valuation of more than $2 billion.
