As AI agents ramp up in the workplace, they\u2019re opening the door to a lot of new cyber risks \u2014 and creating opportunities for a new wave of security startups, even as incumbents in the industry brace for disruption.<\/p>\n

Some of the next-generation startups are using AI agents to significantly scale up how networks are monitored, either through penetration testing or governance \u2014 largely to beat back mass-scale automated attacks that are enabled by AI. Others are wrestling with the critical issue of how agents will verify their identities online as they begin to transact autonomously.<\/p>\n

Investors are paying attention. Xbow, a Sequoia-backed penetration testing startup whose AI agents can probe networks around the clock, is in talks to raise a new funding round that investors expect to value it at just over $1 billion, according to multiple sources familiar with discussions. DFJ is expected to be a major participant in the round, per two of the sources. The round is not yet closed and terms could still change. <\/p>\n

Just today, former Palo Alto Networks founder <\/span>Nir Zuk <\/strong>announced a new AI-native cyber startup called<\/span> Cylake, which is building hardware-based networks for customers whose data is too sensitive for the cloud, such as governments and defense contractors. The company raised a $45 million seed round led by Greylock. <\/span><\/p>\n

Cogent Security, which is using agents to search for network vulnerabilities, raised a <\/span>$42 million Series A two weeks ago led by Bain Capital Ventures, with participation from Greylock Partners and Definition. Another hot penetration testing company that investors told us about is RunSybil, which boasts co-founders from OpenAI and Meta.<\/span><\/p>\n

Agents have been particularly useful at scaling up the capacity for network defense, said Vanta CEO <\/span>Christina Cacioppo, <\/strong>whose compliance startup contracts with nearly a dozen AI security firms. \u201cBecause agents don\u2019t get tired and don\u2019t want vacation, you can fundamentally change the frequency of [testing.]\u201d<\/span><\/p>\n
