FAQ: TLS 1.0 end of life

1. What is TLS?

TLS is an encryption protocol used by web browsers and other systems to make secure connections over the web. The latest versions of this protocol, TLS 1.1 and higher have improved security over earlier versions. That’s why most service providers have phased out or are phasing out support for the older versions and requiring use of TLS 1.1 or newer going forward.

Transport Layer Security (TLS) is a protocol used by applications to communicate securely across a network. In order to better protect your data and that of your users, as of April 1st, 2018, QuestionPro will no longer support TLS 1.0 encryption. After that date, we will support TLS versions 1.1 and above.

2. Why is TLS 1.0 being discontinued?

TLS 1.0 was originally specified in January of 1999. Since then, vulnerabilities have been discovered in TLS 1.0. These vulnerabilities have been addressed and other improvements made in later versions of TLS.

3. How does this affect me? What do I need to do?

As long as you're using an up-to-date web browser, you don't need to do anything - your experience using our tool won't be affected.
If you're using an outdated browser that doesn't support TLS 1.1 or newer, you'll need to upgrade to a new browser to ensure that you can continue connecting to our systems as the phaseout proceeds. If not, you could have:

  • Website access
    • Login issues
    • Website access
    • Signup issues
  • Data collection
    • Survey may not load for your respondents
    • API calls may fail

4. How do I know if my browser supports TLS 1.1 and above?

Browser Supported Version
Internet Explorer 11 and higher
Firefox 27 and higher
Chrome 22 and higher
Andriod 4.4 and higher
Safari (Desktop) 7 and higher
Safari (Mobile) 5 and higher
