Understanding the Vulnerability Landscape in Windows 11
In the ever-evolving digital landscape, the security of our systems has become a critical priority. With the introduction of Windows 11, Microsoft has placed a renewed focus on vulnerability management and mitigation, recognizing the growing complexity and volume of threats facing organizations.
According to the National Institute of Standards and Technology, an astounding 21,957 vulnerabilities were published in 2021 alone. This staggering statistic highlights the immense challenge organizations face in securing their environments and staying ahead of potential attackers. As IT professionals, we must be proactive in managing these vulnerabilities to protect our systems and data.

Addressing this challenge, Microsoft has introduced a comprehensive solution – Microsoft Defender Vulnerability Management. This powerful tool offers a unified approach to vulnerability management, empowering IT teams to reduce cybersecurity risks through continuous assessment, intelligent prioritization, and seamless remediation.
Microsoft Defender Vulnerability Management is now available as a standalone offering, as well as an add-on for Microsoft Defender for Endpoint Plan 2 customers. By integrating this solution into your security arsenal, you can harness the full capabilities of Microsoft’s vulnerability management ecosystem, ensuring your organization is better equipped to safeguard against evolving threats.

Microsoft Defender Vulnerability Management provides a real-time view of your organization’s assets, including software applications, digital certificates, hardware, firmware, and browser extensions. This consolidated inventory empowers you to monitor and assess all your critical assets, even for devices that are not connected to the corporate network.
Intelligent Vulnerability Assessment and Prioritization
By leveraging Microsoft’s threat intelligence, breach likelihood predictions, and business context, Defender Vulnerability Management rapidly and continuously prioritizes the most significant vulnerabilities on your organization’s most critical assets. This risk-based approach ensures you focus your remediation efforts on the vulnerabilities that pose the highest risk to your environment.

Compliance and Security Baseline Assessments
To proactively manage your security posture, Defender Vulnerability Management provides the ability to continuously monitor endpoints and assess their compliance against industry-standard security benchmarks, such as the Center for Internet Security (CIS) and Security Technical Implementation Guides (STIG). This functionality empowers you to identify non-compliant devices and address configuration issues in real-time.
Browser Extensions and Digital Certificates Management
Defender Vulnerability Management introduces new categories of assessments, including a comprehensive inventory of browser extensions and digital certificates across your organization. By providing detailed insights into the permissions and risk levels associated with these assets, you can make informed decisions to manage and mitigate potential vulnerabilities.
Network Share Misconfiguration Assessments
Recognizing the potential risks associated with network shares, Defender Vulnerability Management now includes a new category of configuration assessments that identify common weaknesses in Windows network shares. This feature helps you gain visibility into excessive share permissions and take proactive steps to address these attack vectors.
