Tenable’s market share leadership in Worldwide Device Vulnerability and Exposure Management is a testament to the trust tens of thousands of customers place in Tenable One every day. Our placement also marks seven consecutive years at #1.

Exposure management is the new standard

Tenable’s #1 market share ranking in the IDC: “Worldwide Device Vulnerability and Exposure Management Market Shares, 2024” (IDC #US53330526, August 2025) is a recognition of something we’ve believed all along: exposure management is the future of proactive security. We pioneered this market more than eight years ago, and it’s transforming how organizations measure and reduce cyber risk.

This ranking comes on the heels of another milestone: Tenable was recently named a Leader in the IDC MarketScape: Worldwide Exposure Management 2025 Vendor Assessment (doc #US52994525, August 2025).

“The transition to exposure management is not merely a shift in strategy; it is a fundamental evolution in how organizations perceive and mitigate risks.”

—Michelle Abraham, Senior Research Director, Security and Trust at IDC.

How IDC defines the shift from vulnerability management to exposure management

IDC draws a clear line between traditional vulnerability management and modern exposure management. As they put it, “Device vulnerability management involves scanning for CVEs and potentially prioritizing the findings for remediation. Exposure management goes further than vulnerability management in providing a holistic view, emphasizing the fusion of multiple exposure sources by bringing together CVEs, unknown assets, misconfigurations, and other types of exposure.” That’s exactly why we believe exposure management is gaining traction: it gives organizations the complete visibility they’ve been missing.

For customers, that means fewer silos, stronger analytics and faster time to action. In June 2025, Tenable acquired Apex Security to integrate AI security into Tenable One, accelerating how customers can search, analyze and take action.

“The transition to exposure management is not merely a shift in strategy; it is a fundamental evolution in how organizations perceive and mitigate risks,” said Michelle Abraham, Senior Research Director, Security and Trust at IDC. That evolution is what we’re helping customers embrace every day.

What to look for from an exposure management vendor

IDC didn’t just measure market share, it also laid out recommendations for what exposure management vendors should offer their customers. These recommendations highlight what we believe are the real-world needs of security teams.

Below are IDC’s recommendations, and how we believe they translate into outcomes with Tenable One:

1. IDC recommendation: Be the holistic source of exposure data.

Tenable opinion: The Tenable One platform unifies data from more than 300 third-party tools and Tenable’s own sensors, giving security teams a single, AI-powered view of exposures across the modern attack surface. With correlation and attack path analytics layered in, you can zero in on the exposures most likely to be exploited.

2. IDC recommendation: Move beyond ticketing.

Tenable opinion: Tenable One streamlines remediation through automation. Whether it’s Tenable Patch Management, which pairs autonomous patching with prioritization and threat intelligence, or integrations with leading IT Service Management platforms, such as ServiceNow and Jira, you can close the loop on exposures without adding more manual work.

3. IDC recommendation: Integrate real-time threat intelligence.

Tenable opinion: Tenable One weaves threat intelligence into every step. The Tenable Vulnerability Priority Rating uses multiple threat feeds to predict the likelihood of near-term exploitation activity based on Machine Learning models. And Tenable Attack Path Analysis shows you exactly how attackers might move through your environment, so that you can cut them off before they get started.
