HTTPS vs HTTP
HTTPS is encrypted and secure; HTTP is not. Browsers and security tools prefer HTTPS.

HTTPS is the secure version of web traffic (you see a padlock); HTTP is unencrypted. Our link checker marks HTTP links as suspicious.
HTTP (Hypertext Transfer Protocol) sends data in plain text. HTTPS adds encryption (TLS/SSL) so that data cannot be read or altered in transit. Browsers show a padlock for HTTPS and may warn on HTTP.
Our link safety checker flags HTTP URLs as suspicious because they are not encrypted. Prefer HTTPS for any site where you enter data or credentials.
