Check SSL certificate: Defenseark.com

The entire testing process is very fast and takes place in milliseconds. If you are the owner of the domain in question and the SSL test shows that the website does not use a valid SSL certificate, then consider purchasing a valid SSL certificate.

SSL Certificate Verification Process

The SSL certificate checking process takes place in the following stages:

A request to review the SSL certificate is sent via the online form on this webpage for a specific domain.
Our server first resolves the domain into an IP address (for example, the domain name Defenseark.com resolves to the IP address 76.76.21.21) and then connects to the website's server to request a digital identification (SSL certificate).
The server of the requested domain sends us a response in the form of a copy of the SSL certificate (if they have one)
Our tool checks whether it is a valid SSL certificate and displays the result of the verification process, including the certificate chain.

Below is a complete overview with all visible details after checking the SSL certificate for the requested domain, along with the final conclusion.

Enter the new domain for which you want to check the SSL connection and find out if it uses a valid SSL certificate or not.
