Tenable Plans to Acquire Vulcan Cyber, Accelerate Leadership in Exposure Management

January 29, 2025 - Tenable Holdings, Inc. , (“Tenable”) (Nasdaq: TENB) the exposure management company, today announced that it has signed a definitive agreement to acquire Vulcan Cyber Ltd. (“Vulcan Cyber”), a leading innovator in exposure management. Vulcan Cyber's capabilities will augment Tenable's industry-leading Exposure Management platform, enhancing customers' ability to consolidate exposures across their security stack, prioritize risks and streamline remediation efforts across the entire attack surface.

Under the terms of the agreement, Tenable will acquire Vulcan Cyber for approximately $147 million in cash and $3 million of restricted stock units (RSUs) that vest over a future period. The acquisition is expected to close in the first quarter of 2025, subject to customary closing conditions.

“CISOs are overwhelmed with scattered security products, siloed tools and disjointed teams which makes protecting their organizations from exposure a massive undertaking. As the pioneer behind Exposure Management, we are driven to solve this central challenge of modern security — a fragmented approach to identifying and combating cyber risk,” said Steve Vintz, Co-CEO and CFO, Tenable. “That is what this acquisition is all about. With Vulcan, we're accelerating our Tenable One vision to radically unify security visibility, insight and action across the attack surface – from the data center to the cloud – to rapidly expose and close the gaps that put businesses at risk.”

Tenable plans to expand the Tenable One Exposure Management Platform with Vulcan Cyber's robust capabilities, including enhanced visibility, extended third-party data flows, superior risk prioritization, and optimized remediation. By consolidating and aggregating vast amounts of data into the most comprehensive Exposure Management platform, Tenable is empowering organizations to confidently reduce risk across their entire environment.

“These capabilities aren't just technical enhancements – they represent a fundamental shift in how organizations will manage cyber risks holistically into the future. For example, while having a cloud security platform is critical on its own, its power is exponentially amplified when treated as part of a comprehensive exposure management approach,” said Mark Thurmond, Co-CEO and COO, Tenable. “By uniting disparate tools and data under one roof, we're providing security teams with a full-spectrum view of their attack surface, enabling them to prioritize what matters most and act decisively to address vulnerabilities.”

A Unified Vision for Exposure Management

With the addition of Vulcan Cyber, Tenable One customers will gain:

• Expanded Third-Party Ecosystem Data: By integrating with more than 100 security products across vulnerability assessment, endpoint security, cloud security, application security, and threat intelligence, Tenable will ingest, normalize, and unify data across the security stack. This streamlined approach centralizes critical data and empowers security teams to operate more efficiently and proactively across the entire attack surface.
• AI-Powered Risk Prioritization: Siloed security products create blind spots where attackers thrive, leaving critical gaps across the attack surface. Enhanced risk prioritization closes these gaps by integrating enriched threat intelligence and context, helping organizations focus on the most critical vulnerabilities while optimizing the use of their security tools and technology.
• Automated Remediation Workflows: Optimized remediation with automated campaigns, advanced tagging and ticketing ensure that security issues, along with corrective guidance, get into the hands of the right security team members to automatically fix exposures quickly, wherever they might exist in their environment.
• Advanced AI capabilities: Leveraging a single unified risk data set, Tenable is laying the foundation for advanced exposure AI capabilities that will revolutionize how customers manage and mitigate risk across the security stack.

“We're thrilled to join forces with Tenable. Integrating Vulcan Cyber's capabilities into the Tenable One platform will uniquely address all exposure management use cases across the entire attack surface,” said Yaniv Bar-Dayan, Co-Founder and CEO, Vulcan Cyber. “For the first time at scale, security teams will be able to consolidate exposure findings from multiple sources into a single, actionable interface. We are excited to start working with Tenable and their customers to remediate exposure risk.”
