Tenable intends to acquire AI attack surface company Apex Security. Tenable believes the acquisition, once completed, will strengthen its ability to help organisations identify and reduce cyber risks.
“Apex delivers the visibility, context, and control security teams need to reduce AI-generated exposure proactively,” said Tenable Co-CEO Mark Thurmond. “It will be a powerful addition to the Tenable One platform and a perfect fit for our pre-emptive approach to cybersecurity.”
Founded in 2023, Apex attracted early interest from CISOs and top investors, including Sam Altman (OpenAI), Clem Delangue (Hugging Face), and venture capital firms Sequoia Capital and Index Ventures.
The company quickly emerged as an innovator in securing the use of AI by developers and everyday employees alike, addressing the growing need to manage usage, enforce policy, and ensure compliance at scale.
“The AI attack surface is deeply intertwined with everything else organizations are already securing,” said Apex Security CEO Matan Derman. “Treating it as part of exposure management is the most strategic approach. We’re excited to join forces with Tenable to help customers manage AI risk in context, not as a silo, but as part of their broader environment.”
Following the acquisition close, Tenable expects to deliver integrated capabilities in the second half of 2025 as part of Tenable One.
The financial terms of the deal were not disclosed. The deal is expected to close later this quarter.
