The crypto-agility control plane · Trust that outlives the algorithm
NewGive every AI agent a post-quantum identityAgile Digital Trust for the Quantum-AI Era
4Quays is the crypto-agility control plane. Change the cryptography inside your enterprise by policy, not by rebuild.

Your systems are built to last. The cryptography inside them isn't.
Enterprises run on systems that will outlive the cryptography inside them. 4Quays upgrades that cryptography in place, across the systems you already run, so a new algorithm becomes a policy change instead of a replacement program.
Your applications, and the AI agents now acting on their behalf, both depend on cryptography you did not write and cannot easily change. 4Quays keeps both quantum-safe, and keeps every agent action signed, attributable and verifiable.
Why now
Timelines are set
Addressing quantum and AI risk requires new cryptography and a new security model. Timelines are set and regulation is underway, so enterprises must prepare now.
- PQC
- Algorithm deprecations
- Vendor risk
- AI growth
- Sovereign concerns
Data has a long shelf life
Regulation raises the bar
Demand for unique skills will converge
The problem
Cryptography is buried in everything you run
Cryptography is hardcoded by vendors into everything, separately, by everyone. It accumulated through integration decisions, not by design. Nobody has a complete map, and nobody owns it end to end.
- Applications and APIs
- Legacy systems
- Cloud and databases
- PKI and identity
- Devices and firmware
- OT / ICS
- AI agents
- Third-party supply chains

Slow and risky
Discovery is necessary. Safe implementation and remediation are the bottleneck, and that is what 4Quays solves.

Integrate once, change through policy
Four capabilities that turn a per-team implementation problem into a central decision.

It connects to what you already run
Discovery pulls cryptographic assets out of cloud, code, network, endpoint and AI-agent sources. Evidence goes back out to the security tooling your teams already watch.

AI
On both sides of the problem
AI is on both sides of this problem. It is another surface to protect, and it is part of how the control plane does the protecting.

The product
See it work
A four-minute walkthrough: discovering cryptographic assets, defining policy centrally, and migrating a live service to ML-KEM-1024, without the application ever touching key material.
Securing agentic AI
Trust relationships at machine speed
AI agents build trust with each other at machine speed, far faster than certificates, keys and identity processes were ever designed to move. At the same time, AI keeps shortening the gap between a weakness appearing and being exploited.
4Quays applies one enterprise cryptographic policy across every direction an agent communicates: human-to-AI, human-to-machine, AI-to-AI, AI-to-machine and machine-to-machine. The keys, certificates and identities behind your agents stay post-quantum ready, and agents sign, verify and encrypt messages without being redesigned.

Who's behind 4Quays
People who have run this before
4Quays is built by people who have spent their careers running the cryptography that regulated institutions depend on, and who now help write the standards the rest of the industry will follow.
Policy-driven change
Staged and reversible
Ready for what comes next
The team has operated Protected B Cloud at Level 3 with 24/7 security operations under ITSG 22, 28 and 33, running access and entitlements for dozens of federal departments, in environments certified to ISO 27001, 27017 and 27018.
