Tenable to Acquire AI Security Startup Apex

**Executive summary:** Tenable announced plans to acquire Apex, an Israel-based AI-security startup founded in 2023 that surfaces ungoverned AI activity (shadow apps, AI-generated code, fake identities); Apex will be integrated into Tenable One to extend the AI Aware capabilities by helping mitigate AI-related risks and enforce security policies. Financial terms were not disclosed and the acquisition is expected to close in the second half of 2025, complementing Tenable's recent acquisitions such as Vulcan, Eureka, and Ermetic.
