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<\/a>, not just because it’s recommended. <\/p>\n\n\n\n

This will assist in protecting and preventing any information from your website or visitors from being tampered with or eavesdropped on.<\/p>\n\n\n\n

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. <\/p>\n\n\n\n

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

This article offers a few techniques to help you determine which version of TLS is being used on your website.<\/p>\n\n\n\n

Details about Different Versions of TLS:<\/h2>\n\n\n\n

The more recent TLS versions, like 1.2 and 1.3, have better security features than the outdated ones, like 1.0 or 1.1. If the outdated versions of TSL that are still in use on your consumers’ websites allow hackers to steal or disclose personal data, putting them vulnerable to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

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

Methods to Check the TLS Version of your Website<\/h2>\n\n\n\n

Method 1: Directions for Verifying a Domain’s (Hostname) TLS Version Using a TLS Checker<\/h3>\n\n\n\n

Step 1: <\/strong>Check out the https:\/\/www.ssllabs.com\/ssltes<\/strong>t 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. <\/p>\n\n\n\n
