We have detected you are using a browser that uses TLS 1.0 or below as the protocol to encrypt data during secure sessions.
TLS 1.0 is insecure and is no longer supported by Comodo websites. We advise all affected users to upgrade to the latest versions of their browser or make changes to disable TLS 1.0 and below.
Please use the following links to upgrade your browser:
Option 1 (Preferred) – upgrade to the latest version of Internet Explorer at http://windows.microsoft.com/en-us/internet-explorer/download-ie, or Microsoft Edge at https://www.microsoft.com/en-us/download/details.aspx?id=48126 (Windows 10 only)
Option 2 – update settings in your existing browser
Make sure all other TLS 1.0 and all SSL protocols are disabled
Option 1 (Preferred) – Upgrade to the latest version of Firefox at https://www.mozilla.org/en-US/firefox/desktop/
Option 2 – Update settings in existing browser. Firefox no longer has an interface to modify protocol settings so you will need to directly modify the integer values in the about:config page:
Changing the setting will force Firefox to use TLS 1.1 or better
Option 1 (Preferred) – Upgrade to the latest version of Chrome at http://www.google.com/chrome/
Option 2 – Update settings in existing browser.
There are no options for enabling SSL protocols. If you are using Safari version 7 or greater, TLS 1.1 and TLS 1.2 are automatically enabled. If you have an earlier version, please upgrade at https://support.apple.com/en-us/HT204416
