Website security check
Inspect bounded DNS, certificate, TLS, redirect, header, and cookie-attribute evidence for a public hostname. See the evidence first, then conservative findings—without a misleading letter grade.
Bounded public scanner
Check one hostname
The scanner resolves public DNS and makes bounded requests from TechnicalEntropy’s Azure region to ports 80 and 443. Only the entered hostname and its redirect chain are assessed.
The target website receives bounded requests from the TechnicalEntropy Azure scanner, not from your browser or public IP address. Scan only sites you are authorized to assess.

Results are never saved automatically or synchronized. This browser keeps at most 20 explicitly saved runs and removes entries after 30 days.

Know the boundary
One endpoint, not a security audit.
This is a point-in-time observation of one validated IPv4 endpoint and a bounded redirect chain. It does not scan every load-balanced server, test application vulnerabilities, or prove that a website is comprehensively secure. IPv6 DNS is reported, but IPv6 reachability is not tested.
