It indicates that the domain does not support HTTPS or lacks an SSL/TLS certificate entirely. This means communication between the client and the server occurs over unencrypted HTTP, exposing sensitive data to interception or tampering.
Three questions every analyst asks before acting on this signal.
It indicates that the domain does not support HTTPS or lacks an SSL/TLS certificate entirely. This means communication between the client and the server occurs over unencrypted HTTP, exposing sensitive data to interception or tampering.
Because without SSL/TLS, transmitted data—such as credentials, cookies, or session tokens—can be intercepted or modified by attackers. The lack of encryption also makes phishing or spoofing pages harder to detect by browsers.
No. Some legacy or misconfigured domains may simply lack proper setup. However, in modern infrastructures, the absence of SSL is rare for legitimate services and is often seen in low-quality, abandoned, or malicious sites.
