Enhancing On-Premises and Exchange Server Security: Automated Mitigation Strategies

In a digital landscape where online options for Exchange Server are prevalent, a significant number of companies still find value in maintaining on-premises servers. While this choice offers its benefits, it also exposes these organizations to potential cyber threats. Particularly concerning are the heightened risks associated with the latest versions of on-prem Exchange Servers (2013, 2016, and 2019) that are under the radar of cybercriminals. To counter these challenges, Microsoft is taking proactive measures in collaboration with its partners to bolster security and respond effectively to emerging threats.

Addressing this pressing concern, Microsoft has rolled out a range of solutions, including updates, comprehensive step-by-step guidance, and powerful mitigation tools. However, the latest development in this ongoing battle is the introduction of an innovative automated update aimed at fortifying cybersecurity.



Streamlined Security with Microsoft Defender Antivirus’s Automatic Mitigation

The newest update in this lineup focuses on the automatic mitigation of the CVE-2021-26855 vulnerability on Exchange Servers. With its deployment, Exchange Servers equipped with this update gain the capability to promptly identify this vulnerability and take immediate corrective actions to safeguard the server’s integrity.

The beauty of this solution lies in its simplicity. Users are no longer burdened with complex mitigation processes; instead, their responsibility is centered around ensuring that they possess the latest security update or have automatic updates enabled. This streamlined approach doesn’t replace the significance of Exchange security updates; rather, it complements them.
