Test Results Summary for www.imperial.ac.uk
- The server on the tested port is currently not prepared for post-quantum key exchange. The server’s certificate chain relies entirely on classical signature algorithms without post-quantum support. Show details.
- 1 SSL/TLS end-entity certificate detected: the first certificate is a trusted RSA 2048 bits certificate with issuer YR1 valid until January 22, 2027. 1 certificate chain detected. Show details.
- 8 of 17 supported cipher suites are not compliant with PCI DSS. The server supports only PCI DSS compliant protocols: TLSv1.2 and TLSv1.3. All supported elliptic curves are compliant with PCI DSS: P-256, P-384 and X25519. There is 1 more issue which makes the server non-compliant with PCI DSS: potential Marvin Attack. Show details.
- 9 of 17 supported cipher suites are not compliant with HIPAA requirements (Ref. NIST SP 800-52). The server supports only HIPAA compliant protocols: TLSv1.2 and TLSv1.3. All supported elliptic curves are compliant with HIPAA: P-256, P-384 and X25519. There is 1 more issue which makes the server non-compliant with HIPAA: certificate does not include an OCSP responder url. Show details.
- No issues related to industry best practices were identified. Show details.
