When SSL Labs (Qualys) is the better choice

We'd rather be honest than waste your time.

Security engineers debugging a specific TLS handshake or cipher configuration.

  • You need the deepest possible TLS analysis (every cipher suite, protocol downgrade, OCSP stapling).
  • One-off manual check of a public domain without an account.
  • You don't need monitoring, email, DNS, accessibility or compliance reporting.

When SiteGuardian is the better choice

  • You want continuous monitoring and alerts, not one-off scans.
  • You need EU data residency and GDPR-by-design processing.
  • You need TLS + DNS + email + headers + accessibility + cookies in one report.
  • You need findings mapped to NIS2, GDPR, DORA, DSA, EAA, CRA articles.
  • You want to benchmark your score against 700k EU sites.
