What is Cross Certification and how does it affect me?
The certificate used in ESET products is signed by a trusted certification authority (TRCA), and this TRCA can be signed by different TRCAs. The mutual trust relationship between two specific TRCAs is expiring and will not be renewed, as the digest algorithm is SHA-1, which is no longer secure.
Newer ESET products use more secure and up-to-date certificate chains that meet security standards and do not expire on April 15, 2021.
This issue is not dependent on the Windows operating system version, and if you have the ESET products mentioned below, it will happen on Windows with the latest updates.
What will happen?
Affected ESET products will no longer update modules, including the detection engine after April 15, 2021. These ESET products will not be fully functional and will be unable to provide sufficient protection.
