Securing agentic AI
Enterprise cryptographic policy 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.
The same policy, applied to agents
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.

Illustrative scenarios
Where this shows up
The shapes of problem enterprises bring us, across government, retail, financial services and defence.
01
Benefits processing
GovernmentAgents exchange entitlement decisions across departments, each message signed and verifiable under central policy.
02
Autonomous replenishment
RetailMachine-to-machine ordering across a supplier network, with the identities behind each agent kept post-quantum ready.
03
Real-time fraud response
Financial servicesDetection and response agents act at machine speed while every instruction stays attributable and auditable.
04
Mission coordination
DefenceCoordinating agents operate across disconnected environments without weakening the cryptography behind them.
