What We Assess

8 Areas We Examine

01
Certificate Validity & Expiry
We check every cert on every endpoint for expiry date, issuer trust, and Subject Alternative Name coverage.
02
Certificate Chain Integrity
Intermediate and root cert trust path, cross-signing, and client-fetch-order correctness.
03
Protocol Versions
TLS 1.3 enabled? Deprecated SSLv3/TLS 1.0/1.1 disabled? Fallback behaviour safe?
04
Cipher Suite Strength
Weak and legacy ciphers flagged (RC4, 3DES, NULL), preferred order checked, AEAD suites verified.
05
Forward Secrecy
ECDHE / DHE key exchange enforced so past traffic stays confidential if the server key is ever compromised.
06
HSTS & Strict Transport
HSTS header, max-age, includeSubDomains, preload list eligibility, and redirect-chain hygiene.
07
OCSP Stapling & Revocation
OCSP stapling enabled, Must-Staple flag, CRL distribution points, and revocation-check behaviour.
08
CAA Records & Transparency
DNS CAA records restricting which CAs can issue, and SCT/Certificate Transparency log presence.
Who This Assessment Is For

Any organisation running HTTPS: public websites, customer portals, APIs, mail servers, VPN concentrators. Especially important for regulated sectors, payment gateways, and anyone carrying sensitive data in transit.

Common Findings We Uncover
Certificate expired or expiring within 30 days
TLS 1.0/1.1 still enabled on production endpoints
No HSTS header, or HSTS with max-age too low
Weak cipher suites (RC4, 3DES, CBC without ETM)
Missing CAA records — any CA can issue for your domain
Compliance Frameworks Mapped

Common Questions

Why does TLS configuration matter if my cert is valid?
A valid certificate is only one layer. Weak ciphers, deprecated protocols, or missing HSTS mean attackers can still downgrade connections, intercept traffic, or coerce clients into HTTP. Configuration hygiene is where most real-world TLS breaches happen.
How often should we audit our TLS setup?
At minimum quarterly, and any time you rotate certificates, add an endpoint, or change load balancers. TLS recommendations move fast — what was Mozilla "intermediate" two years ago may be weak today.
Do you test internal endpoints or only public ones?
Both. The free AI assessment focuses on internet-facing endpoints you tell us about; the full engagement with our team covers internal services, mTLS configurations, and service-mesh certificates.
