The PCI Security Council is the body responsible for creating and enforcing rules on which technologies are acceptable for use in transmitting cardholder payment data. As such, they've explicitly identified that TLS 1.0 is no longer an adequate form of data encryption as it is vulnerable to many known attack methods. Due to this, ZeroBounce no longer supports TLS 1.0 and 1.1.
ZeroBounce joins the company of most company websites in adapting to the latest versions of TLS for better customer security and privacy.
If you are not a ZeroBounce API user, it's doubtful that the change will affect you. There may be a few outlying scenarios if you operate on an old, outdated browser or operating system.
To determine if your current operating system or browser supports TLS 1.2 or higher, test your system for free courtesy of Qualys SSL Labs.
If you are a ZeroBounce API user and have any code that connects with any API endpoint, you'll need to ensure that it will continue to work. Every programming language and API library is different, so your mileage may vary.
The languages listed below will require significant changes or upgrades to support TLS 1.2 or higher:
Please be advised - ZeroBounce doesn't have experts for every programming language or framework. You'll need to test and update your code as needed to support the ZeroBounce API.
Below, you can find some additional instructions for various versions of .NET:
Please refer to Microsoft's developer guidance for more support for TLS System Default Versions included in .NET.
All modern browsers now support TLS 1.2 and higher. You will only experience an impact if you're using an outdated version of a web browser.
The following web browsers do not support TLS 1.2:
If you're using one of these browsers or older versions, consider upgrading as soon as possible to support TLS 1.2 and higher for better payment security.
