TLS Version Checker

What is a TLS Checker?

A TLS Checker is an online tool used to verify the security and validity of your website’s SSL/TLS certificates. By inspecting various factors such as expiration dates, encryption protocols, and certificate authorities, this tool ensures your site’s communication channels are properly protected.

Uses and Purpose

Website owners, developers, and security professionals rely on a TLS Checker to keep track of certificate health. It helps ensure that all certificates are valid, trusted, and up to current security standards. By doing so, it prevents vulnerabilities like expired certificates or weak encryption algorithms from compromising your site’s security.

Problems It Solves

• Expired or Soon-to-Expire Certificates
  • Quickly identify when a certificate is about to expire so you can renew it before it impacts user trust.
• Misconfigurations
  • Detect issues like improperly chained certificates or unsupported encryption protocols that may result in browser warnings or errors.
• Security Vulnerabilities
  • Pinpoint potential weaknesses, such as outdated TLS versions and cipher suites, helping you avoid attacks like man-in-the-middle breaches.

Benefits of Regular TLS Checks

• Compliance: Stay aligned with industry standards (PCI DSS, GDPR) by ensuring robust encryption and data protection.
• User Trust: A secure site boosts user confidence and loyalty, ultimately improving brand reputation.
• Easy Maintenance: Simplify certificate management, reducing downtime or disruptions caused by unforeseen certificate errors. 

Why Use Our TLS Checker?

With just a few clicks, you can gain detailed insights into the health and reliability of your site’s SSL/TLS certificates. Our user-friendly interface makes it easy to spot and resolve issues, helping you maintain a secure and seamless experience for your visitors. Don’t leave your site’s security to chance.

What is a TLS?

TLS, or Transport Layer Security, is a cryptographic protocol designed to securely communication over a computer network. It encrypts data exchanged between a client (like a web browser) and a server (like a website), ensuring that sensitive information—such as login credentials, credit card details, and personal data—cannot be intercepted or tampered with by unauthorized third parties. TLS is the successor to SSL (Secure Sockets Layer) and is widely used across the internet to protect everything from email and instant messaging to web browsing and online transactions.

What is a SSL?

SSL certificates are short data files that establish a secure connection between a web server and a browser using cryptography.
This connection ensures that all information exchanged between the web server and the browser is kept private. 

Before TLS (Transport Layer Security) was introduced in 1999, Secure Sockets Layer (SSL) was the most extensively used cryptographic system for providing security over internet connections.
Even though the SSL protocol has been deprecated and TLS has been adopted in its stead, most people still refer to this type of technology as "SSL." 

The SSL certificate uses the secure sockets layer (SSL) protocol to establish secure connections with the user's browser.
The SSL certificate, which digitally binds company information to a cryptographic key, is required to establish this secure connection. 

SSL certificate information

An SSL certificate helps secure information such as:

•     Credit card transactions or bank account information
•     Login credentials
•     Legal documents and contracts
•     Personally identifiable information — such as full name, address, date of birth, or telephone number
•     Medical records
•     Proprietary information

How to Check SSL Certificate?

By clicking on the green (grey or blue) lock icon on the left side of your browser's address bar, you may view and check the SSL certificate of a website.
Your web browser will show you all of the information about the SSL certificate that is accessible.
You may also use our free SSL security test to check your SSL certificate's validity and correct setting.

Make sure your SSL/TLS certificate and web server are properly set up. After setting up SSL/TLS on your server and website or making any configuration changes, it is vital to ensure that everything is set up correctly and that your system is secure.

Conclusion

Staying up-to-date on TLS protocol versions is essential in maintaining a secure and trustworthy online presence. With the TLS Version Checker, you can quickly identify outdated protocols, strengthen your site’s defenses, and protect your business and user data. Regularly monitoring and updating your TLS settings ensures you remain compliant with evolving industry standards, boosts user trust, and keeps your site performing at its best
