How do you Check the TLS Version of your Website?

A technology called Transport Layer Security (TLS) is used to protect internet communications. It is the updated version of SSL that is used for encryption by HTTPS and other network protocols. Over the years, TLS went through several modifications. It is required of you to update your TLS versions, not just because it’s recommended.

This will assist in protecting and preventing any information from your website or visitors from being tampered with or eavesdropped on.

Website owners and administrators must know what version of TLS they have in operation. Some versions include (TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3). It is advisable to periodically check your TLS version; this way, you will be proactive in keeping your site safe.

There are more vulnerabilities with older versions hence, you need to ensure that Security has been taken care of in your website.

This article offers a few techniques to help you determine which version of TLS is being used on your website.

Details about Different Versions of TLS:

The more recent TLS versions, like 1.2 and 1.3, have better security features than the outdated ones, like 1.0 or 1.1. If the outdated versions of TSL that are still in use on your consumers’ websites allow hackers to steal or disclose personal data, putting them vulnerable to man-in-the-middle attacks, you risk losing their trust.

Employ the latest Transport Layer Security (TLS) protocols on all of your websites to ensure that your customers are reliable and secure.

Methods to Check the TLS Version of your Website

Method 1: Directions for Verifying a Domain’s (Hostname) TLS Version Using a TLS Checker

Step 1: Check out the https://www.ssllabs.com/ssltest webpage. The website is scanned by this free TLS-checking tool, which then generates a report with the TLS version, supported protocols, cipher suites, and other details.

• First, type the hostname (such as www.twitter.com) into the “Hostname” section and press the Submit button.

• Before beginning the scan, turn off any privacy extensions or ad blockers you may be using, such as uBlock Origin or Privacy Badger.

• Check the box next to “Do not show the results on the boards” if you prefer that the domain you are looking for stay off SSL Labs’ list of recent inquiries.

• Up to three minutes may pass during the scan. When the scan is finished, the server’s IP address will get a letter grade (like A+ or D) next to it.

Step 2: Click the IP address of the website. If the website is routed to several servers, you will see each server’s IP address in the results. You can check the TLS version for every server individually.

Step 3: See all TLS versions with the checkmark next to them by swiping to the “Configuration” section.

• You can find a list of all TLS versions under the “Protocols” section under “Configuration,” along with a clear “Yes” or “No” indicating which versions are supported. Every TLS version with the label “Yes” is configured on this page.

• Additionally, you will find other supported protocols, cipher suites, supported SSL versions (if any), and whether the website is vulnerable to any existing vulnerabilities.

Method 2: Figuring out Which TLS Versions Your Browser Supports

• Visit https://browserleaks.com/tls to verify the TLS version you are using. This website will assess the versions of TLS that your current web browser—Chrome, Safari, and Edge—supports.
• There is a list of all TLS versions, from TLS 1.0 to TLS 1.3, under “Protocol Support” The versions of your browser that are supported are marked “Enabled” with a green checkmark.
• Disable any privacy-focused browser extensions or add-ons you may be using, such as Privacy Badger, and then refresh the page. These extensions could render it impossible for Browser Leaks to determine the TLS version of your browser.
• Simply launch a new window in your preferred web browser. You should type howsmyssl.com into your browser’s address bar. This will instantly inform you of the TLS version that your web browser supports.

Method 3: Utilising Microsoft Edge to Verify the TLS Version

• Navigate to the Microsoft Edge website.
• With a right-click on the page, choose “Inspect.” To click the page with a one-button mouse, use Ctrl + click. This launches the page’s developer view.
• After clicking the two arrows >>, choose Security. The right panel will display a menu bar with a “Welcome” tab on its far left side. Clicking >> will take you to the Security tab.
• The TLS version can be found under “Connection.” You can find further details on the encryption and the TLS version here.

Conclusion:

To ensure that your website is secure, you should check the TLS version of your website from time to time. This is because hackers always use new and innovative ways to access systems through web pages.

That’s it! We hope you found this helpful. Now it’s your turn: Find out what TLS protocol versions your company supports.
