IT services organization chooses Tenable over Microsoft

The Situation

A multibillion-dollar IT services company sought to strengthen its security posture, improve vulnerability remediation efficiency, and create consistent cyber risk management processes across its diverse clients’ infrastructure. Initially, the company evaluated Microsoft for vulnerability management. However, the IT Security Manager quickly discovered key limitations, including a lack of visibility across non-Microsoft assets, weak external scanning capabilities, and challenges integrating with broader hybrid environments. These shortcomings created unacceptable risk for a service provider responsible for securing multiple clients’ infrastructures.

The Decision

The company needed more than Microsoft’s limited endpoint-focused approach: it required full visibility, flexibility and security compliance support across client environments. Here’s why the company chose Tenable:

• Comprehensive visibility across diverse environments – Tenable provides full-spectrum coverage across on-premises, cloud, containers and non-Microsoft assets — addressing critical blind spots that Microsoft’s endpoint-based solution can’t reach.
• Streamlined policy and segmentation management – Tenable enables intuitive segmentation and custom policy application across client environments, making it easy to manage security at scale without losing oversight or flexibility.
• Built-in support for security compliance – With robust reporting and broad asset coverage, Tenable helps the organization meet complex regulatory demands across industries — reducing audit time and increasing confidence in compliance readiness.

Business Impact

By choosing Tenable, the IT services company realized significant business benefits: Protection against increased risk – The full-spectrum visibility provided by Tenable eliminates blind spots left by Microsoft’s endpoint-centric approach, reducing the likelihood of undetected vulnerabilities impacting clients.

• Risk mitigation – Tenable prioritizes remediation based on actual business risk, not just severity scores, which help teams act faster and focus efforts where they matter most.
• Cost reduction – Granular policy and segmentation controls simplify security operations across client environments, reducing administrative effort and overhead.
• Cost avoidance – Early detection and proactive response to vulnerabilities can prevent costly breaches.
• Adopt innovations with confidence - Tenable One, the leading exposure management platform, enables organizations to adopt new technologies for a competitive edge without delay.
