In June last year we updated you on our plans to deprecate TLS 1.0 and 1.1 due to a mandate by the PCI Security Standards Council. However, year ago, we decided to not roll out the change to all our services due to number of legacy applications that still required TLS 1.0 and 1.1.
Since then, we’ve observed a significant reduction in legacy TLS traffic on our network and because most of the modern browsers now supports TLS 1.2+ and will drop support for TLS 1.0 and 1.1 in early 2020, we decided, as part of our continued commitment to maintain a secure platform, to deprecate support for TLS 1.0 and TLS 1.1 on all our services on December 4th.
Most of our customers will not be affected by this change as they are already using modern browsers and HTTP clients. .
If you are using Filestack APIs programmatically please verify with your programming language and operating system documentation that your HTTP client supports TLS 1.2. For example, Python 2.7.8 (and earlier) and Java 7 (and older versions of Android) do not support TLS 1.2 by default.
If your applications are using the Filestack Picker or CDN you can confirm browser version compatibility with your users by using SSL/TLS Capabilities of Your Browser and User Agent Capabilities list at https://www.ssllabs.com/ssltest/viewMyClient.html
