Check SSL certificate details, expiration dates, issuer information, and security protocols for any website. Ensure your SSL/TLS configuration is secure and up to date.
Ensure your website's SSL/TLS configuration is secure and up to date
Verify certificate validity and encryption strength
Track certificate expiration to prevent service disruption
Ensure PCI DSS, HIPAA, and other compliance requirements
Quick certificate analysis without installation
Follow these guidelines to maintain secure SSL/TLS configuration
Set reminders to renew certificates at least 30 days before expiration. Most CAs now offer 90-day certificates for better security.
Use TLS 1.3 or TLS 1.2, disable TLS 1.0/1.1, use strong cipher suites with forward secrecy (ECDHE), and enable HSTS.
Perform regular SSL/TLS security audits, test for vulnerabilities like POODLE, Heartbleed, and ROBOT attacks.
Everything you need to know about SSL certificates
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. It ensures that data transferred between a user's browser and the web server remains private and secure.
As of 2020, SSL certificates are valid for a maximum of 398 days (approximately 13 months). Most CAs issue certificates valid for 90 days to 1 year. It's recommended to set up auto-renewal to prevent expiration.
When an SSL certificate expires, browsers display security warnings to visitors. This can severely impact user trust, reduce conversions, and negatively affect SEO rankings. It's critical to renew certificates before expiration.
A certificate chain is a hierarchical list of certificates that connects your SSL certificate to a trusted root certificate authority (CA). It includes the leaf certificate (your domain), intermediate certificates, and the root certificate.
SAN (Subject Alternative Name) certificates allow you to secure multiple domain names with a single certificate. For example, you can secure example.com, www.example.com, mail.example.com, and api.example.com all in one certificate.
DV (Domain Validation) only verifies domain ownership. OV (Organization Validation) verifies business identity. EV (Extended Validation) provides the highest level of verification and displays the company name in the browser address bar.
