We build security where there is a genuine gap. Cyron API Security sees what runs. Cyron AI Security measures what your agents do with it. Cyron AI Compliance, in development, will prove what happened. Each stands on its own; on your own infrastructure, the first two already run as one loop.
See: kernel-level API security
An eBPF kernel agent copies REST, WebSocket, gRPC and streaming traffic out of band, so nothing is added to your request path. Cyron detects business-logic abuse, account takeover and data leaks, and blocks the source at the kernel.
Measure: security for AI agents
Agent boundary protection for MCP and A2A. It inspects tool lists, tool calls and tool responses, blocks the threat classes you name, and records every detection as evidence.
Prove: EU AI Act and ISO 42001
The governance layer, in development. It is being built to consume evidence produced by live measurement, map it to regulatory duty elements, keep a qualified human at the point of judgement, and write the filing itself.
They are sold separately and deploy independently. On your own infrastructure, two of them are already one system. Cyron On-Premise installs Cyron API Security and Cyron AI Security together. One kernel sensor captures API and agent traffic, each product judges its own layer, and the sensor blocks the source. See how the loop works.
| Layer | Product | What it answers | What it hands on |
|---|---|---|---|
| See | Cyron API Security | What is actually reaching my APIs, and which of it is abuse? | Behavioural findings and forensic incident reports |
| Measure | Cyron AI Security | What did my AI agents send to their tools and to each other, and what was stopped? | Durable findings, each classified to a public standard |
| Prove | Cyron AI Compliance | Which regulatory obligations are discharged, by what evidence, and until when? | In development: attested filings and an auditable gap register |
Every product starts with a real, underserved gap and an offensive understanding of how it gets exploited. Four refusals hold across all three.
Cyron API Security analyses a copy of your traffic, so your requests never wait for it. Where Cyron blocks, the block is precise: an attacker’s address, or the agent threat classes you have named.
Where nothing has been seen, we never report “safe”. Cyron AI Security’s transparent control status report shows exactly what is inspected.
Both products run on your own infrastructure. Cyron AI Security runs fully air-gapped, with signed offline updates. Prefer a service? Cyron API Security is also offered as SaaS, hosted in Germany.
Cyron AI Compliance is being built so that no obligation is discharged because someone ticked a box. Where only an assertion exists, the filing will say so.
