Connect Safely via Cyphers Proxy

[cyphers] Endpoint Tools allow you to connect safely to a server even though it will allow for insecure connections. Your connection will be secure regardless of the server's security posture.

These proxies don't modify the remote server — they enforce TLS best practices on your side of the connection. Traffic is routed through the Cyphers proxy network which negotiates the strongest available cipher suite and rejects connections that fall below your configured threshold.

Findings

1 Minor
4 Info
Headers
HSTS MINOR
-10 pts
HTTP Strict Transport Security (HSTS) header is not set
PCI-DSS 2.2.7
Observed: Strict-Transport-Security header missing
Expected: HSTS header with max-age >= 31536000
Remediation: Add HSTS header. For nginx: add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";
WHY THIS MATTERS
First-time visitors can be intercepted via man-in-the-middle attacks. Critical for authentication endpoints where credentials are transmitted.

Protocol
TLS 1.3 Support INFO
TLS 1.3 is supported
Certificate
Certificate Validity INFO
Certificate is valid for 67 more days
! OCSP Stapling INFO
-5 pts
OCSP stapling is not enabled
Observed: No OCSP response in TLS handshake
Expected: OCSP stapling enabled for faster revocation checks
Remediation: Enable OCSP stapling. For nginx: ssl_stapling on; ssl_stapling_verify on;
WHY THIS MATTERS
Performance optimization that reduces latency for certificate revocation checks. Not a security vulnerability, but improves user experience.

Certificate Transparency (SCT) INFO
-5 pts
No Signed Certificate Timestamps (SCT) found
Observed: No SCT in TLS handshake or certificate
Expected: SCT present for Certificate Transparency compliance
Remediation: Use a CA that supports Certificate Transparency. Most modern CAs include SCTs by default.
