Post-quantum security for AI agents talking to each other.
AI agents now negotiate and act with other agents over the network. Why that traffic is a target, why today's protections are not quantum-safe by default, and what the Synapse Protocol adds.
AI agents increasingly talk to other agents: they request data, place orders and make decisions with no person in between. That traffic carries credentials and authority, so it is a prime target. The Synapse Protocol gives agent-to-agent communication a post-quantum handshake and a verified identity on both ends.
A new kind of traffic.
Protocols such as Google's Agent2Agent let AI agents from different vendors discover each other and work together. Each exchange can carry API keys, customer data and the authority to act. Compromise the channel and you can impersonate the agent.
Quantum-safe is not the default.
Most agent traffic rides on TLS. Its key exchange is quantum-safe only where the hybrid post-quantum mode, X25519 with ML-KEM, is switched on at both ends, and identities are still signed with classical algorithms. An agent conversation recorded today can be read after Q-Day.
A handshake built for the post-quantum era.
The Synapse Protocol establishes keys with ML-KEM and verifies identities with ML-DSA, so both secrecy and authenticity survive a quantum computer. Combined with VISUM, an agent's traffic also stays inside the jurisdiction it is allowed in.
Where it is today.
The protocol is fully architected and proven in a browser-based simulation. The seed round funds the production implementation.
Short answers
Straight answers to what investors and partners ask us first.
Agent2Agent, an open protocol introduced by Google in 2025 that lets AI agents from different systems communicate and coordinate.
Only where post-quantum key exchange and signatures are used. Most deployments today rely on classical cryptography for identity.
Protecting what agents can access and do: their credentials, their channels, and their identity, so they cannot be read, hijacked or impersonated.
