Tenable Ranks #1 in Device Vulnerability and Exposure Management

Tenable® (NASDAQ: TENB), the exposure management company, today announced that it has been ranked first for 2024 worldwide market share in the IDC Worldwide Device Vulnerability and Exposure Management Market Shares (doc #US53330526, August 2025) report. 

Exposure Management is the future of proactive and preventive security, delivering a transformational shift in how organizations measure and reduce cyber risk. Tenable attributes its position as a leading player in the exposure management space to its early adoption of these concepts, strengthened by a robust partner ecosystem and channel-first strategy.

The Tenable One platform unifies data from more than 300 other security tools and Tenable’s own sensors, giving security teams a single, AI-powered view of exposures across the modern attack surface. By normalizing and correlating this data and layering in attack path analytics, Tenable One enables security teams to focus on the exposures most likely to be exploited. 

“We believe seven consecutive years of market share leadership is a testament to the trust our customers place in our Tenable One platform every day,” said Mark Thurmond, co-chief executive officer, Tenable. “We remain focused on pushing the envelope of exposure management solutions that help our customers evolve their security strategies and not just stop breaches, but prevent them before they even happen.”

The IDC Market Shares report notes that Tenable aggregates exposure data in a single platform. With more than 300 integrations, Tenable One is the most open and interconnected exposure management platform on the market. 

The IDC Market Shares report also highlights Tenable’s recent acquisition of Apex Security to integrate AI security into Tenable. Launched in August 2025, Tenable AI Exposure provides organizations with unprecedented visibility into how AI is being used, where risks may exist, and what controls are needed to securely adopt generative AI tools, all integrated into Tenable One. 

According to the IDC Market Shares report, “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. With exposure management solutions, organizations can aggregate, de-duplicate, and analyze data from a variety of sources to provide a more accurate assessment of an organization's risk posture.”

IDC のセキュリティおよびトラスト部門、シニアリサーチディレクターのミシェル・エイブラム氏は次のように述べています。「従来の脆弱性検出機能が変革されて、総合的なリスク管理と修正管理機能となった能動的なエクスポージャー管理が将来を担います。アタックサーフェスが拡大しているので、高度なツールを活用して、隠されたリスクを顕在化させ、エクスプロイトされる前に重大なギャップを塞がなければなりません」

This ranking comes on the heels of another milestone: Tenable was also recently named a Leader in the IDC MarketScape: Worldwide Exposure Management 2025 Vendor Assessment (文書番号 #US52994525、2025 年 8 月) においてリーダーに選出されています。
