In a strategic move to strengthen its cybersecurity capabilities, Tenable Holdings, Inc. has announced plans to acquire Vulcan Cyber Ltd. for approximately $150 million. The acquisition will enhance Tenable’s exposure management solutions and give customers a better way to consolidate potential exposures and improve their cybersecurity defenses.
Adding Vulcan Cyber’s innovative solutions to the Tenable One platform is expected to deliver a wide range of significant new benefits, including expanded visibility, more third-party data flows, superior risk prioritization, and optimized remediation. As a result, security teams using Tenable One can address vulnerabilities more effectively across their entire attack surface.
“I think buying Vulcan is a great tuck-in for Tenable that will help them ward off competition from upstarts in the vulnerability intelligence space,” said Richard Stiennon, an analyst with IT-Harvest and author of Security Yearbook 2025. “$150 million is a good price considering Vulcan has raised $69 million. I estimated the price is four times their annual recurring revenue.”
The acquisition is expected to close in the first quarter of 2025, subject to customary closing conditions and regulatory approvals.

- AI-powered risk prioritization closes visibility gaps and helps companies identify and focus on their most critical vulnerabilities. As a result, security teams can focus on the most critical vulnerabilities while optimizing their use of security tools.
- Automated remediation workflows will simplify the vulnerability management process and ensure that security issues get the attention of the right security teams to fix exposures quickly.
- Advanced AI capabilities that can improve how customers manage and mitigate risk across their entire security stack.
By streamlining risk assessment and remediation, the integration will help security teams address threats more efficiently while maximizing the value of their existing cybersecurity tools.
Industry Context and Future Outlook
Cyber threats are becoming more complex with the rise of cloud technologies, IoT devices, and remote work. These trends expand threat attack surfaces and make vulnerability management more challenging. Threat actors continue to use advanced tactics to exploit weaknesses, which increases the need for comprehensive exposure management solutions that provide actionable security insights.
As threats evolve, exposure management is essential to any cybersecurity defense strategy. Solutions that offer visibility, prioritization, and automated remediation help organizations mitigate risks much more effectively. A more proactive, data-driven approach can help today’s organizations quickly identify and address vulnerabilities before they escalate.
Tenable’s acquisition of Vulcan Cyber marks a significant step in advancing exposure management and helping organizations stay ahead of evolving threats. By integrating Vulcan Cyber’s capabilities into Tenable One, the company is delivering a more comprehensive, automated approach to vulnerability management.
This move not only reinforces Tenable’s leadership in cybersecurity but also gives businesses the tools they need to proactively reduce risk and strengthen their security posture. The combination of these two platforms will provide organizations with greater visibility, smarter prioritization, and faster remediation – essential components of a more resilient and adaptive security strategy.
