"Acquisition of Eureka Security by Tenable enhances Tenable's cloud data visibility"
In the ever-evolving landscape of cybersecurity, consolidation and unification of security capabilities have become a prominent trend. This is evident in the recent wave of acquisitions by large cybersecurity firms, aiming to create integrated platforms that offer comprehensive visibility and response across endpoints, cloud, identity, and SaaS environments.
One such acquisition is Tenable's purchase of Eureka Security, a company specializing in data security posture management for cloud environments. The deal, which was announced in the first half of 2025, is expected to allow Tenable's customers to better identify risky cloud data and who has access to it, providing a more robust security solution.
Tenable, a global leader in cybersecurity, reported $798.7 million in revenue in fiscal 2023 and has approximately 44,000 customers globally. The acquisition of Eureka Security is not expected to have a significant impact on Tenable's revenue this year.
Eureka Security was founded in 2021 by CEO Liat Hayun and CTO Asaf Weiss, both veterans of Palo Alto Networks. The company helps companies prevent misconfigurations by providing a detailed view of their cloud data security footprint. This acquisition will undoubtedly strengthen Tenable's offerings in the cloud security domain.
The market has seen a surge in demand for unified security tools that help companies quickly hunt for threats and mitigate vulnerabilities. This trend is driven by the growing and more sophisticated cyber threats that businesses face today.
Similarly, other cybersecurity giants have been actively acquiring specialized companies to bolster their offerings. For example, Google acquired Wiz for $32 billion, while Proofpoint expanded its Microsoft 365 security offerings for SMBs by acquiring Hornetsecurity Group. Zscaler boosted its managed detection and response (MDR) capabilities with the acquisition of Red Canary, and Sophos expanded its threat detection and response portfolio by acquiring Secureworks. Palo Alto Networks has also signed a deal to acquire IBM's QRadar SaaS assets.
These acquisitions highlight a clear pattern of larger vendors consolidating niche expertise to offer more unified and advanced security solutions. Vendors building platforms can choose to integrate or provide the functionality themselves, as per Erik Nost, senior analyst at Forrester.
In the quest for unified security solutions, AI-powered platforms are playing a significant role. Companies like SentinelOne and CrowdStrike are investing heavily in AI-powered platforms that unify detection and response across multiple layers. For instance, CrowdStrike's acquisition of Adaptive Shield for SaaS Security Posture Management broadens its ability to unify identity protection across on-prem, cloud, and SaaS applications.
In conclusion, the cybersecurity M&A landscape in 2025 is characterised by strategic acquisitions aimed at combining threat detection, response, and vulnerability management into unified platforms powered increasingly by AI, addressing the complexity of modern threats and hybrid environments. The acquisition of Eureka Security by Tenable is a testament to this trend, further strengthening Tenable's position in the cybersecurity market.
