Here at OPSWAT we are continuously updating our products to stay up to date with the latest technology, security, and industry best practices. Keeping with this policy, MetaDefender Access will drop support for TLS 1.1 and TLS 1.0 as of March 31, 2021.
If you are using an older MetaDefender Endpoint version and do not update to TLS version 1.2 (or later) by March 31, 2021, those devices running the older MetaDefender Endpoint will stop working.
For guidance on the minimum version of the MetaDefender Endpoint that supports TLS 1.2, please reference this article.
Note that you will also want to ensure your devices are configured to permit TLS 1.2, In some cases, TLS 1.2 may not be enabled by default.
For those organizations calling the MetaDefender Access API, note that this change will also require using TLS 1.2 (or later) as of March 31, 2021.
As background, TLS 1.0 and 1.1 are out-of-date protocols that do not support modern cryptographic algorithms, and they contain security vulnerabilities that may be exploited by attackers. Most browsers have already, or will soon, start warning users if they use these older protocols (or even block their use all together). The Internet Engineering Task Force is also planning to officially deprecate both protocols.
