Obtain a domain name’s Secure Sockets Layer (SSL) certificate and trace its complete SSL certificate chain to reveal potential inconsistencies and misconfigurations that may translate to exploitable vulnerabilities. A single SSL Certificate Chain API query provides details that can ease your security enrichment efforts, allowing you to know which domains are trustworthy and which are not.Get started

When the SSL certificate and SSL certificate chain result was queried.
The domain name the SSL certificates and the SSL certificate chain belong to.
The IP address resolution of the domain name.
The port number associated with the SSL connection.
All the available SSL certificates in the SSL certificate chain of the domain and their types—end-user, intermediate, or root.
Includes each SSL certificate’s chain hierarchy, validation type, validity dates (from and to), serial number, signature algorithm, subject, issuer details, .pem file information, extension, and public key (Check out the complete output format for more details.).
We provide access to the latest SSL certificate issued for every domain.
We parse the SSL certificate chain data thoroughly to give users information in a format that is easy to read and integrate.
Monitor your SSL certificates and SSL certificate chain for signs of unauthorized changes that may signal a domain or subdomain takeover.
Know which domains can and can’t be trusted by diving deeper into their SSL certificate and SSL certificate chain details.
Check the SSL certificate validation type to detect self-signed certificates often used in man-in-the-middle (MitM) and typosquatting attacks.
Increase visibility into organizations’ attack surfaces to check for SSL certificates that are about to expire or already expired.
Keep up with SSL certificate and SSL certificate chain modifications as domains change hands often.
