From January 14, 2020 Microsoft will no longer offer free updates, patches and technical support for their Windows 7 and Windows Server 2008/R2. Staying with unsupported operating system is a major risk for every company - as attackers will surely try to look for and exploit any vulnerabilities in the end-of-life OS.
What is the scale of this risk? Last year, 499 vulnerabilities have been found in Windows OS (including 100 critical). Additionally, unpatched operating systems were one of the main reasons why the notorious WannaCry ransomware spread so widely. Currently, one in three data breaches (the biggest cybersecurity issue of 2019) is a result of unpatched vulnerabilities. And a single breach or infection can be an end for any business - especially from the SMB sector.
For businesses not ready yet to migrate to Windows 10, Microsoft offers paid Windows 7 Extended Security Updates (ESU) through January 2023.
