Security you can evidence

Security intelligence for APIs, AI agents, and the proof regulators ask for.

Cyron Intelligence builds three products on one loop. Cyron API Security watches live API traffic from the Linux kernel. Cyron AI Security protects what your AI agents send to tools and to each other, and blocks the threat classes you choose. Cyron AI Compliance, now in development, will turn that record into evidence an auditor accepts. The first two are available today and run on your own infrastructure.

The closed loop

See what runs. Measure what it does. Prove what happened.

Three products, each solving one layer of the same problem. Most security stacks can tell you a request was authorised. Cyron also tells you whether the instruction behind it was.

Available · SaaS and On-Premise

Cyron API Security

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.

  • Detection for all ten OWASP API risks
  • Behavioural intelligence, beyond signatures
  • Free plan and published prices; On-Premise by quote
Available · On-Premise

Cyron AI Security

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.

  • Tool poisoning, rug-pulls and secret exfiltration detected
  • Blocking by threat class and severity, chosen by you
  • Findings classified to the OWASP LLM and Agentic Top 10; fully air-gapped
In development

Cyron AI Compliance

Prove: EU AI Act and ISO 42001

The incumbent compliance product is a questionnaire: you assert a control and a dashboard turns green. This one will discharge obligations from measured evidence instead.

  • EU AI Act and ISO/IEC 42001 duty coverage
  • A named human will confirm every mapping
  • Filings will regenerate byte-for-byte from the ledger

Cyron API Security

Kernel-level API security that sees the attacks your firewall waves through.

Available · SaaS and On-Premise

It watches your live traffic without ever touching it.

The iris agent taps your traffic at the Linux kernel with eBPF and copies it out of band across REST, WebSocket, gRPC and Socket.IO, with Server-Sent Events from launch day. Your live request path stays exactly as fast as it was. No SDK, no code changes, no proxy in the way.

  • Kernel-level blocking of the source when an attack is confirmed
  • Catches business-logic abuse, account takeover and data leaks, not just signatures
  • Detection logic for all ten OWASP API risks, with threat-intelligence enrichment
  • System 2 Thinking, the AI analyst, attaches a reasoned verdict to borderline events
  • SaaS hosted in Germany, or the whole platform on your own servers
Available · On-Premise

Cyron AI Security

Enterprises are moving from AI that answers questions to AI that takes actions: calling internal tools, reading customer records, writing to systems, sending data outward. Your network and API controls see an authorised application making authorised calls. What they cannot see is that the instruction arrived inside a poisoned document, a manipulated tool description or a compromised agent-to-agent message.

Cyron AI Security sits at that boundary. It inspects what your agents exchange with tools over MCP and with each other over A2A, blocks the threat classes you name and keeps durable evidence for each detection, classified to OWASP's LLM and Agentic Top 10 lists. It runs on your own infrastructure with no call-home.

In development

Cyron AI Compliance

Auditors, notified bodies and market surveillance authorities are all trained to ask the same question: what evidence supports that tick? Most organisations can produce a policy document. Very few can produce evidence of what their AI systems actually did.

Cyron AI Compliance is being built to consume evidence produced by live measurement, grade it by how it was obtained, map it to EU AI Act and ISO/IEC 42001 duty elements, and require a named qualified human to confirm each mapping and a second to sign the attestation. Where only an assertion exists, the filing will say so.

Why Cyron

What we refuse to do is the product.

A statement of what a system is not is more binding than a statement of what it is, because it is falsifiable. These four refusals hold across all three products.

Never the cause of your outage

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.

Never silence as assurance

Where nothing has been seen, we never report "safe". Cyron AI Security's transparent control status report shows exactly what is inspected.

Never out of your hands

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.

Never a questionnaire

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.

Consulting & Compliance

When a product cannot solve it, a person should.

The problem is new and internal expertise is scarce. Our advisory practice is delivered by the same people who architect the products, which is a different proposition from a consultant who has read the regulation.

AI Act applicability & role

Per AI system, establish whether you are provider, deployer, importer or distributor, classify risk, and produce an attested applicability determination with its basis recorded.

AI governance readiness

Assess your AI management system against ISO/IEC 42001 and the applicable AI Act duties, with a gap report that names, for each unmet duty, whose condition prevents it.

Adversarial testing & red-teaming

Contained adversarial testing of deployed AI systems with a reproducible evidence record, addressing the Article 15 robustness and cybersecurity duties, which apply from 2 December 2027.

Our Mission

Intelligence is the difference between blocking a threat and being able to prove it.

Cyron Intelligence exists to give every organisation, from a first product to a regulated enterprise, security it can evidence rather than assert. We build only where there is a real, underserved gap, and we build it to run where your data already lives.
