Check whether your SSL encryption is working

SSL Encryption

You will receive the result within seconds. If your website is not encrypted with SSL, the following message will appear on your screen:
No SSL Connection.
This notification means that the connection to your website is not protected by an SSL certificate, either because you haven’t installed one, or it has expired or is faulty. If this is the case, you should review the details of your SSL certificate or request a new one. If the SSL test is successful, it will list which certificate you are using, whether it is installed correctly and if there are any safety gaps.

SSL Validation

If your certificate is installed correctly, once you have entered your URL you will receive the following message:
Certificate is installed correctly.
This means that your SSL certificate is installed correctly and is valid. For more details on the checked certificate go to “Certificate information.” “Certificate status” also shows you whether or not your certificate is valid. Remember, even if your certificate is working and valid, you are not automatically protected against all known threats.

Remove errors and possible security gaps

Affected by Heartbleed or BEAST?

Correctly installing and having a working SSL certificate does not guarantee complete protection against all threats. The SSL test shows you which security gaps exist through notifications like the following example:
Warning. BEAST. The BEAST attack is not mitigated on this server.
The SSL checker examines the SSL configuration of the URL for any security gaps. Potential vulnerabilities include:
If the website entered does not pass the Heartbleed test, or one of the other security checks, our tool will let you know and provide advice on how to solve the problem.

Other possible errors

The SSL Checker detects faulty installation, incompatibility with server configurations and details on any security gaps in the certificate you are using. It detects problems in the following areas:
Installation and certificate information:

FAQ – Frequently asked questions
Why should I do an SSL check to see whether my website has an integrated SSL certificate?

Using the SSL checker is important if you run a website that requires the exchange of sensitive data with your clients. The data exchange should always be protected by an SSL certificate, as third parties might otherwise be able to gain access to the information. If you run an online store where the checkout process requires the customer address and payment details, or you host a contact form on your website where interested parties can provide their name and email address, an SSL certificate is a must.

If SSL is installed, you can use the SSL Checker to determine whether there are any potential security gaps which could endanger the data exchange to avoid any potential gaps in your websites.

Can the SSL check help me with problems with my SSL certificate?

Once you’ve installed your SSL certificate, you can use the SSL test to make sure it is working properly. The result will shows whether your SSL certificate is installed correctly and valid. If this is not the case you will receive the notification “Certificate is not installed correctly.” Additionally you will receive a detailed analysis of your server configuration so you are aware of any problems or incompatibility and whether or not you need to modify your server configuration or use a different SSL certificate.
