RIOREY

What RIOREY does

RioRey is a Bethesda, Maryland-based provider of dedicated DDoS detection and mitigation systems, operating continuously in this single domain since 2006. The company's core technology is the RIOS (RioRey Intelligent Operating System) analytics-driven filtering engine, which identifies attacks by methodology rather than by signatures or tool fingerprints, with analytics covering 25 distinct DDoS attack classes across OSI Layers 3, 4, and 7 (e.g., SYN Flood, UDP Flood, DNS Flood, HTTP Fragmentation, ICMP variants, and Layer 7 application attacks). Detection begins automatically from the first packet without baseline learning or tuning.

The product portfolio spans purpose-built hardware filtering appliances covering 10G to 100G throughput (the RE10, RS40, and RE100 family, with peak filtering capacity of 80 million packets per second), rVM (virtual machine filtering from 1.5M to 50M PPS running on customer infrastructure), rCloud (cloud-based volumetric scrubbing delivered via a joint venture with Inter.link and live since October 2024 with EU-based scrubbing centers), Director (netflow/sflow-based detection and traffic steering supporting BGP redirect, FlowSpec, RTBH, and ACL actions), and rWeb (a browser-based management and reporting platform with multi-tenant zones, REST API for billing/operations integration, and real-time visibility). The same RIOS engine runs across every deployment form factor, enabling consistent detection logic in hardware, virtual, and cloud deployments.

RioRey targets service providers and ISPs, hosting and cloud operators, enterprise and financial institutions, and government and public sector organizations. The commercial model mixes capex or hardware subscriptions for appliances with recurring rVM (from $480/month) and rCloud (from $516/month at 36-month terms) subscriptions, supplemented by managed services and professional services. Pricing is published on the website for rVM and rCloud, while hardware pricing and large deals go through direct sales; trials are self-serve with approval. The company is privately held with 11-50 employees, references private investor Dr. Jeong Kim, and discloses no institutional venture or private equity backing. Named customers include FilmOn (digital media) and Iskon, Croatia's largest telecommunications provider.
