Cyron.IO - AI-Powered API Security Guard

Cyron API Security Guard is a production-grade, multi-protocol API security platform. It
detects and blocks API-layer attacks in real time, explains every decision with on-device AI forensic
reasoning, and runs either as a managed European-hosted service or fully air-gapped on a
customer’s own infrastructure. This document summarises what the product does and how it fits into
an existing environment.
What Cyron does — the detection pipeline
Every API request passes through four complementary layers. Faster layers act first; deeper, costlier
analysis is reserved for genuinely ambiguous events.
• Deterministic rules and policy. Recognises known attack patterns — injection, traversal,
enumeration, protocol abuse — and policy violations, and blocks them instantly.
• Behavioural intelligence. Learns normal usage and flags anomalies across sessions and protocols:
credential stuffing, scraping, account enumeration and business-logic abuse.
• Threat-intelligence correlation. Enriches live traffic against curated IP-reputation and threat feeds
to catch known-bad sources in milliseconds.
• AI “System 2” forensic reasoning. An on-device language model investigates ambiguous events
and produces a plain-language forensic dossier explaining what happened and why it was flagged.
Protocol coverage
Cyron inspects HTTP, WebSocket and gRPC (including deep Protocol-Buffer payloads) — not only
REST. Detection runs at the kernel level, so coverage stays consistent across protocols and transport
types, including real-time and streaming APIs that legacy, REST-first tools miss.
How Cyron fits into your environment
• Out of the critical path. Cyron observes traffic through a lightweight kernel-level sensor (extended
Berkeley Packet Filter) or an asynchronous mirror — it does not sit as a fragile synchronous proxy.
• Fail-open by design. Only confirmed threats are blocked; if the sensor or service is ever
unavailable, legitimate traffic is never dropped.
• Start in monitor-only mode. Observe and validate first, then enable selective real-time blocking
when ready.
• Low overhead. Sub-35-millisecond p99 added latency (internal benchmark).
• Deploys without re-architecting. For most environments a single load-balancer target change;
alternatively bring-your-own-certificate or automatic certificate provisioning. The agent is a single
binary — no root and no container required — and installs in minutes.
Deployment models
Cyron SaaS — fully managed and European-hosted (data residency in Germany), with continuous
threat-intelligence updates and subscription billing. The fastest way to start.
Cyron On-Premise — the complete platform runs inside the customer’s own network, fully air-gapped:
cryptographically signed licensing, per-customer encrypted detection models, offline threat-intelligence
updates and no outbound “call-home”. Built for regulated organisations that cannot route API traffic off
site.
Forensics, integration and visibility
• Explainable forensic reports for every significant event — not just an alert score.
• Real-time incident dashboard with live detections and blocked activity.

Cyron API Security Guard
• SIEM integration via signed webhooks into existing security tooling.
• Automatic API and endpoint discovery to inventory what is actually exposed

Who it is for
Custom pricing
Cyron is built for organisations that expose APIs and need protection without surrendering control:
financial services and fintech, healthcare and government, API-first software companies, and teams
securing AI and agentic workloads. The on-premise model is designed specifically for regulated
environments with strict data-residency requirements.
