With a record 1,360 flaws in 2024 and 25 actively exploitable zero-days in 2025, Microsoft is the most targeted vendor.1 Relying on its internal security is a conflict of interest; you need independent oversight. Tenable provides superior breadth and reliability for true exposure management across heterogeneous environments.

Why customers choose Tenable over Microsoft
Prioritize risk
Prioritize risk
Tenable Exposure View combines Tenable’s vulnerability priority rating (VPR) with an asset criticality rating (ACR) to objectively measure the risk of an asset, a business unit, or the whole organization.
Microsoft scores do not consider context like internal and peer benchmarking, assessment, and remediation maturity.
Microsoft security recommendations focus on configuration changes within their own stack leading to hundreds and thousands of suggestions.
Security beyond the endpoint
Security beyond the endpoint
Tenable has complete visibility and assessment of your entire attack surface.
Reducing cyber risk and ensuring compliance requires understanding across traditional IT to the cloud to operational technology.
Tenable’s ability to log on to network devices and check for configuration and setting significantly reduces the rate of false-positives.
Microsoft Defender Vulnerability Management coverage is limited to those endpoints that have an agent, and its network scanning capability is SNMP-based.
Microsoft has deprecated its Windows authenticated (credentialed) scans as of December 2025, creating a massive visibility gap for customers.
Coverage and accuracy
Coverage and accuracy
As of March 2026, Tenable Research has published more than 315K plugins covering over 116K CVEs. We continue to update and publish our vulnerability coverage and CVE count at tenable.com/plugins.
Tenable enables communication by providing an extensive library of dashboards and reports to help facilitate communication with stakeholders such as senior leadership, IT and security colleagues, auditors, and the board.
Microsoft optimized reporting for its Microsoft ecosystem and lacks a unified exposure score across IT, OT, IoT, and multi-cloud environments.
Simplified licensing and cost
Simplified licensing and cost
Tenable pricing and licensing removes “security math,” double-charging and financial penalties for premium features common for Microsoft.
Microsoft is notorious for a complex web of additional licenses or consumption-based fees to unlock product value.
