Security Posture Assessment
A clear-eyed review of how you would hold up against a motivated attacker, with findings ranked by real risk, not raw CVSS.
Intelligence-Driven Cybersecurity
Security intelligence for APIs, AI, and the teams defending them.
eBPF kernel-level
2 ms detection
EU data residency
GDPR, PCI-DSS, NIS2 aligned
Flagship Product
cyron.io
Kernel-level API security that sees the attacks your firewall waves through.
Live
It watches your live traffic without ever touching it.
The iris agent runs as a single Docker container and taps your traffic at the Linux kernel with eBPF. It mirrors requests out of band across HTTP, WebSocket and gRPC, so your live request path stays exactly as fast as it was. No SDK, no code changes, no proxy in the way.
- About 2 ms to flag a threat, with kernel-level blocking when you want it
- Catches business logic abuse, account takeover and data exfiltration, not just signatures
- Full OWASP API Security Top 10 coverage, enriched by 7 threat intelligence feeds
- System 2 Thinking writes plain-English forensic reports for every incident
- EU-hosted, with on-premise and air-gapped options. Raw payloads are never stored
In ideation
Cyron AI Security
Every team is shipping AI features. Almost none can prove they are safe. Cyron AI Security is our next product: a security layer for AI, LLM and agentic systems, covering the OWASP LLM Top 10, the model context protocol, runtime guardrails and AI governance from ISO 42001 to the EU AI Act.
We are in the ideation phase and raising a seed round. If you back security companies early, we want to talk.
Consulting & Compliance
When a product cannot solve it, a person should.
Our consultants study your real attack surface, model the threats that matter, and get you audit-ready against the standards your customers ask about.
Threat Modeling
STRIDE and MAESTRO-style modeling of your architecture, including the new failure modes that come with AI and agentic features.
Compliance Readiness
Practical paths to ISO 27001, ISO 42001, SOC 2, the EU AI Act, NIS2, GDPR and PCI-DSS 4.0. We close gaps, not just write reports.
Why Cyron
Built by people who attack systems for a living.
We are offensive security practitioners first. That perspective shapes every product and every engagement.
Real-time, not after the fact
cyron.io flags threats in about two milliseconds and can block them at the kernel before the response leaves.
Behavior over signatures
We learn what normal looks like for your APIs, then surface the abuse that pattern matching never catches.
Prudent AI, not theatre
AI earns its place where it adds signal, like forensic reasoning and anomaly detection. Everywhere else we keep it deterministic.
Privacy by design
Raw payloads are never stored. Hosting sits in the EU, with on-premise and air-gapped options for regulated teams.
Gap-first engineering
We only build where there is a real, underserved gap. If a problem is already solved well, we will tell you to use that.
SaaS or white-label
Self-serve for fast-moving teams, white-label for platforms and managed security providers who want it under their own brand.
Our Mission
Intelligence is the difference between blocking a threat and understanding it.
Cyron Intelligence exists to give every organization, from a first product to a regulated enterprise, the kind of security insight that used to be reserved for the few. We anticipate threats instead of only reacting to them, and we hold the intellectual property behind cyron.io and the products that follow.
