Free SSL certificates are available to anyone, including phishing sites. A padlock only means the connection is encrypted — not that the site on the other end is legitimate.
Check if a URL is actually safe →An SSL (TLS) certificate enables HTTPS on a website, encrypting all data between your browser and the server. Without it, anyone on the same network can read what you send — including passwords and payment details. A valid certificate also proves the website is operated by a real, verified entity rather than an impersonator.
HTTPS means your connection is encrypted — it does NOT mean the website itself is trustworthy. Phishing sites routinely use HTTPS with free certificates. Always check the domain name carefully, and use SafeSearchScan's URL Checker to verify whether a site is known to be malicious, even if it has a padlock.
An expired certificate means the website's security hasn't been renewed. Modern browsers show a warning page when this happens. Don't enter any personal information on a site with an expired certificate — your data would be transmitted unencrypted.
Certificate Transparency (CT) is a public log where all issued SSL certificates are recorded. Our SSL checker queries these logs to show you all certificates ever issued for a domain — which can reveal if a site has a suspicious history of certificate changes or if a fraudulent certificate was issued for a domain you trust.
Enter any domain to get full SSL certificate details in seconds.
