The acquisition of Apex Security adds a powerful new layer of visibility, context and control to the Tenable One Exposure Management Platform to govern usage, enforce policy and control exposure across both the AI that organizations use and the AI they build.
Over the past 25 years, we’ve seen the attack surface shift dramatically — from traditional on-prem environments to cloud, to OT/IOT, and more. But the changes we’re seeing right now with AI feel different. Faster. More disruptive. And, frankly, more unpredictable.
That’s why I’m excited to share that Tenable has signed a definitive agreement to acquire Apex Security, a company we’ve been following for some time. They've built a powerful product that solves real problems in the emerging world of AI risk. Their focus is helping organizations secure both the AI they use and the AI they build — a problem that's becoming more critical every day.
It’s clear we’re in the early stages of a major shift. Developers are integrating large language models into products and internal tools. Employees are using generative tools in everyday workflows. AI is everywhere — but the tools to manage that risk at scale? Not so much.
Last year, we introduced AI Aware to help organizations get visibility into shadow AI. It’s been incredible to see how quickly customers adopted it — more than 6,400 customers in over 100 countries are using it today. But we also heard loud and clear: visibility isn’t enough. Security leaders want to govern usage, enforce policy, and prevent exposures before attackers take advantage. That’s exactly what Apex was built to do.
Their technology adds a powerful layer of visibility, context, and control to what we’re building with Tenable One - our exposure management platform for your entire enterprise. Once the deal closes, we will move quickly to integrate these capabilities into the platform.
This isn’t just about adding another feature — it’s about helping customers take action during a critical window of time. Most organizations haven’t yet experienced a large-scale AI-driven attack. That’s the point. We have a unique opportunity to get ahead of the threat — to define how AI is secured before attackers define it for us.
I’m proud of the team at Tenable for continuing to lead in Exposure Management, and I’m looking forward to welcoming our future teammates from Apex once the deal closes. This is how we stay in front of the attack surface — by seeing where it’s going, and building for it now.
More to come soon.
