You're asking:
"How do I control who connects?"
The answer is TLS done right — and mTLS when you need access control. Here's what that means and why it matters.
"Can I trust the server?"
"I have HTTPS" isn't enough
Most developers think: "I have HTTPS, so I'm secure." But not all TLS is created equal. The configuration matters.
| Configuration | What It Means | Risk |
|---|---|---|
| TLS 1.0/1.1 | Protocols from 1999/2006 | Vulnerable to BEAST, POODLE |
| TLS 1.2 with CBC | Block cipher with padding | Padding oracle attacks |
| Weak ciphers | RC4, 3DES, export ciphers | Breakable with modern hardware |
| TLS 1.3 + Authenticated Encryption with Associated Data (AEAD) | Modern protocol, authenticated encryption | With [ Cyphers ] |
of TLS configurations accept weak cipher suites
still support TLS 1.0/1.1 from 1999
vulnerable to at least one documented attack
The Solution: Server Authenticated TLS (HTTPS)
We refuse weak configurations:
No configuration = No misconfiguration.
"Can I control who connects to my server?"
What you've tried (and why it's not enough)
API Keys
Can be stolen from logs, environment variables, or intercepted in transit.
OAuth Tokens
Passing tokens through AI prompts feels wrong — because it is. Still interceptable.
"Just HTTPS"
Server proves identity to you. But you don't prove identity to the server.
Standard HTTPS
Mutual TLS (mTLS)
The Killer Feature of mTLS
With mTLS, an attacker can't even complete a TCP handshake without a valid certificate.
Without mTLS:
Attacker can: probe endpoints, send requests, brute force, exploit vulnerabilities
With mTLS:
No Cert = No Connection. Attack surface: zero.
Why haven't you done this already?
"Setting up a CA is a whole project. Then I need to issue certs, manage rotation, handle revocation..."
Cyphers Hub does this for you. One click to issue, automatic rotation.
"Commercial client certificates cost $30-75 per year. EACH. For 500 users, that's $15,000-37,500/year."
With Pro, Unlimited Client Certificates for Free.
"I'd need to understand PKI, certificate chains, trust stores, OCSP, CRLs..."
Drop-in products. No PKI knowledge required. We handle it.
Get started in 5 minutes
Three products for three platforms. Same Server Authenticated TLS (HTTPS). Same free tier.
Free tier includes: Server Authenticated TLS (HTTPS) + 5 client certificates + 2 endpoints.
Same security as Pro. Limits are on scale, not quality.
