Test Results Summary for pdus-test-at1.proofpoint.com
- 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 an untrusted RSA 4096 bits certificate with issuer Sectigo Public Server Authentication CA OV R36 valid until March 25, 2027. 2 certificate chains detected. Show details.
- All 3 supported cipher suites are compliant with PCI DSS. The server supports only PCI DSS compliant protocols: TLSv1.2. The server supports PCI DSS compliant elliptic curves (P-256, P-521 and P-384) as well as non-compliant elliptic curves (secp256k1). There is 1 more issue which makes the server non-compliant with PCI DSS: certificates are untrusted. Show details.
- All 3 supported cipher suites are compliant with HIPAA requirements (Ref. NIST SP 800-52). The server supports only HIPAA compliant protocols: TLSv1.2. The server supports HIPAA compliant elliptic curves (P-256, P-521 and P-384) as well as non-compliant elliptic curves (secp256k1). There are 3 more issues which make the server non-compliant with HIPAA: server does not support OCSP stapling, server does not support TLS 1.3, server does not support extended master sECret. Show details.
- 2 issues related to industry best practices were identified: server does not support TLS 1.3, server does not provide HSTS. Show details.
