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.

N8N Cyphers Node

Drop-in workflow node. Routes HTTP requests through Cyphers proxy with enforced TLS 1.2+ and certificate pinning.

Install Node →

Claude Proxy MCP

MCP server for Claude Code / Claude Desktop. Proxies all tool-initiated HTTP calls through a TLS-validated tunnel.

Configure MCP →

OpenAI SDK Toolkit

Python / TypeScript wrapper. Patches the OpenAI SDK transport layer to enforce strict TLS validation on every API call.

View SDK Docs →

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.

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.
