Frequently Asked Questions

Is Domain Security Scanner a good Qualys SSL Labs alternative?

Domain Security Scanner complements SSL Labs rather than replacing it.

For a complete domain security audit, Domain Security Scanner provides broader coverage in a single scan.

Does Qualys SSL Labs check email authentication?

Why is Domain Security Scanner faster than SSL Labs?

SSL Labs performs extremely deep TLS protocol analysis including cipher suite enumeration and handshake simulation, which can take 2-3 minutes.
