Checking Your Browser

Under "Protocol Support," you'll see a list of all TLS versions, from TLS 1.0 to TLS 1.3. Your browser's supported versions are labeled "Enabled" with a green checkmark.

To enable TLS 1.1 and/or TLS 1.2 protocols on Internet Explorer, follow the instructions below. From the menu bar, click Tools > Internet Options > Advanced tab. Scroll down to the Security group, check the option box for Use TLS 1.1 and Use TLS 1.2. Click OK.

Open the Tools menu (click on the tools icon or type Alt - x) and select Internet options. Select the Advanced tab. Scroll down to the bottom of the Settings section. If TLS is not enabled, select the checkboxes next to Use TLS 1.0, Use TLS 1.1, and Use TLS 1.2.

Rackspace strongly recommends enabling the Transport Layer Security (TLS) protocol 1.2 or newer on Windows Server. As of the end of 2020, TLS versions 1.0 and 1.1 are no longer supported.

TLS 1.2 being published in 2008 would then have an expected life of 22years to 2023 however we expect it to be longer than this. One reason to change version is vulnerabilities and TLS1. 2 has a lot of vulnerabilities caused by the older cryptographic algorithms that it still supports for compatibility reasons.

However, SSL is an older technology that contains some security flaws. Transport Layer Security (TLS) is the upgraded version of SSL that fixes existing SSL vulnerabilities. TLS authenticates more efficiently and continues to support encrypted communication channels.

How do I check my TLS 1.2 connection on Windows? ›

Select Start > Settings > System > About. Open About settings. Under Windows specifications, check which edition and version of Windows your device is running. If your operating system was manually changed to disable TLS 1.2 for some reason, you can verify or configure your system for TLS 1.2.

Verify TLS (or SSL) inspection is working

Go to a site where TLS inspection is applied by your web filter. Verify the building icon is in the address bar. Click it to see details about permissions and the connection. (Optional) To see details about the certificate, click Certificate information.

The easiest way to know if a site is SSL encrypted or not is to check its URL. The URL of the site should start with HTTPS. For more details about the site's security credentials, you can click on the padlock icon near the address bar and get more information on the site's SSL certificate details.

Step 1: Press Win + I to open Run, type inetcpl. cpl, and click OK to open the Internet Properties window. Step 2: Under the Advanced tab, scroll down to find Use TLS 1.2. If it is not selected, check the box and tap on Apply.

In the Internet Options window, select the Advanced tab. In the Advanced tab, under Settings, scroll down to the Security section. In the Security section, check Use TLS 1.1 and Use TLS 1.2. Click Apply, then click OK.

Based on TLS 1.1, TLS 1.2 was released by the IETF in 2008 with the RFC-5246. To date, it's the most commonly used TLS protocol version. It's supported by 99.9% of the websites analyzed by SSL Labs (as of January 2023). Yup.
