Machines talk.
We make sure no one else is listening.
Cyphers builds security infrastructure for automation workflows and AI agent communications. Plug-in solutions built on decades of enterprise and government security expertise.
The systems running your business are talking to each other.
Who's securing those conversations?
Your automation workflows call APIs, move data, connect systems. Your AI agents access tools, databases, and internal resources. Every connection is a potential exposure.
The tools that make this possible weren't built with enterprise security in mind. Cyphers lets you add it without slowing down.

Claude Code Discussion How does Claude access internal APIs?

Transport Layer Security (TLS) is the Answer.
In Fact it's the Gold Standard, but only when done right.
"Can I trust the server?"
78% of TLS configurations accept weak ciphers. Most systems still support TLS 1.0/1.1 from 1999.
With [ Cyphers ] = TLS 1.3 only, Authenticated Encryption with Associated Data (AEAD) ciphers, strict validation. No weak options.
Learn More"Can I control who connects to my server?"
Standard HTTPS only proves the server's identity. OAuth tokens can be intercepted. API keys can be stolen.
mTLS = Client must prove identity with certificate. No Cert = No Connection.

With [ Cyphers ] you can implement Enterprise-Grade HTTPS and mTLS quickly and easily. Your existing systems. No weak points. No certificate rotation issues. No expensive client and server certificates.
TLSMCP: mTLS for MCP
Control who connects to your MCP server
Right now, anyone with the URL can access your MCP server. TLSMCP adds mTLS so only approved clients can connect. No certificate = no TCP handshake.
HTTPS for n8n
Trust the servers your workflows call
Your workflow calls 50 APIs. Can you trust them? Drop in the Cyphers HTTPS Node for TLS 1.3, proper validation, and no weak ciphers.
HTTPS for Claude
Give Claude access to internal APIs
Internal APIs require client certificates. The Cyphers HTTPS MCP Server gives Claude the credentials to access zero-trust networks and regulated systems.
Free tier includes: Server Authenticated TLS (HTTPS) + 5 client certificates + 2 endpoints. Same security as Pro. See pricing →
See Your Security Working... and Where It Isn't.
Provision certificates. Manage rotation. See who's connecting. Hub handles the PKI complexity so you don't have to.
- TLS 1.3: 100% — see With [ Cyphers ] enforced.
- 3 clients connected — know who's using mTLS.
- 2 rejected — proof access control works.
Built by engineers who've done this before
The Cyphers team has decades of experience and a proven track record delivering security solutions to the most demanding customers. We have built FIPS-compliant platforms for enterprises, achieved numerous Common Criteria validations, and implemented post-quantum cryptography from first principles. We know what it takes to develop, deploy, support and certify systems where failure isn't an option.
Regulated Industries
Financial services, healthcare, government. You need audit trails and provable controls. We build for your requirements first.
Enterprise Security Teams
Your developers are deploying automation and AI faster than you can review. Cyphers gives you visibility and governance without slowing them down.
Platform Engineering
You're building the infrastructure that AI and automation run on. Cyphers provides the security layer so you don't have to build it yourself.
5 minutes. Free to start.
Pick your platform. Add Server Authenticated TLS (HTTPS). Get mTLS when you need access control. Same security as Pro — limits are on scale, not quality.
