Agile 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.

The 4Quays control plane, showing cryptographic inventory and policy status

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
01

Data has a long shelf life

Sensitive data stolen today is exposed to future decryption. The clock on anything you hold started running before you began migrating.
02

Regulation raises the bar

NIS2, the Cyber Resilience Act, sector regulators, and your insurers and partners, now expect secure-by-design systems and demonstrable resilience.
03

Demand for unique skills will converge

Migrations will accelerate as standards and vendor transitions converge, while cryptographic engineering skills remain scarce.

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
01

Hidden

No one can see every dependency. Inventories are partial, and stale the moment they are written.
02

Specialized

Each team must correctly implement unfamiliar cryptography, a scarce engineering skill.
03

Slow and risky

Every change means testing, redeployment and coordination. Quarters, per system.

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

The platform

Integrate once, change through policy

Four capabilities that turn a per-team implementation problem into a central decision.

Explore the platform
01

Observe

Import and discover cryptographic assets and dependencies across connected environments, giving you a live inventory (CBOM) instead of a stale spreadsheet.
02

Execute

Orchestrate approved cryptographic change through supported APIs and agents. After the initial integration, your teams don't implement each new algorithm themselves.
03

Govern

Define central policy over algorithms, keys and providers, whether classical, hybrid or post-quantum, decided centrally rather than per team.
04

Prove

Monitor, audit and remediate continuously. Evidence flows into your SIEM and audit workflows, with controlled rollback if anything misbehaves.

Reach

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.

01

4Q Agent, your cryptographic expert

Ask about your own estate and get an answer: what the CBOM contains, which assets are quantum-vulnerable, how ready each service is, what to migrate first. It reads and explains. It never executes changes, and it signs its own answers so any response can be verified.
02

Agents as cryptographic principals

Enroll an AI agent and it gets its own ML-DSA signing key, and optionally an ML-KEM encryption key, under policy. Rotate them, mint one-time signing grants, or revoke on the spot.
03

Anomaly detection and alerting

Rules evaluate continuously over latency, error rate, throughput and payload volume, firing on a threshold, on deviation from a baseline, or on the absence of activity you expected to see.
04

Discovery that finds your agents

Connectors for Bedrock Agents, OpenAI Agents, Entra Agent ID and agent frameworks in source, so the agents running in your estate appear in the inventory alongside your services.

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.

What it means

What this changes for your organization

01

No mandatory rip and replace

Quantum-safe uplift inside the systems and investments you keep.
02

Teams out of the crypto business

No scarce cryptographic expertise to hire or build in-house.
03

Audit-ready evidence

Compliance proof lands in the security and audit tools you already use.

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.

01

Policy-driven change

Decide centrally, then apply with visibility and controls through policy.
02

Staged and reversible

Hybrid adoption, live observability and controlled rollback.
03

Ready for what comes next

Algorithm changes are pre-tested for operations, not multi-year programs.

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.
