TLS, which stands for Transport Layer Security, is a cryptographic protocol that provides secure communication between servers. It ensures that data transmitted over a network, such as through web browsers or applications, remains encrypted and protected. However, on 30th June 2018, the Payment Card Industry (PCI) mandated the discontinuation of support for TLS version 1.0 due to its weakened cryptographic strength.
Engaging Networks will disable TLS 1.0 on 1st June 2018 at 1 pm EDT / 6 pm BST in line with this requirement. This update will be implemented without downtime, meaning there will be no interruption in the platform's availability. It is a necessary step to enhance the security of data transmission and align with industry standards.
Here are the steps you can follow to enable TLS in different browsers:
Firefox
1. Type "about:config" in the URL.
2. Search for "security.tls.version.max"
3. Change the value to 3 ---> This will enable TLSv1.3
Note: These steps will be applicable for Firefox 23.0 or later versions
Chrome
1. Click the wrench icon
2. Choose Setting
3. Show advanced setting
4. Click Change proxy settings
5. Select the "Advanced" Tab
6. Scroll down and check TLS 1.0
7. Close and restart all open browsers
Internet Explorer
1. Click the wrench icon
2. Click on "Internet Options"
3. Select the "Advanced" Tab
4. Scroll down and check TLS 1.0 
5. Close and restart all open browsers

That's all.
