Off-Ramp or In-Line Filtering:
DDoS Defense Appliances for Every Network
DDoS filtering hardware
Same filtering intelligence. Regardless of how you deploy.
RioRey hardware runs RIOS, our analytics-driven filtering software, directly on purpose-built appliances. Every device covers all 25 attack classes across Layer 3 to Layer 7, deploys in minutes, and operates automatically without signatures or manual rules.
What every RioRey device delivers
Filtering starts within minutes of powering up
No signatures to load, no rules to write, no learning period. RIOS analytics begin protecting your network automatically from the first packet. RioRey is designed not to drop legitimate traffic even during the heaviest attacks.
TCP, TCP-HTTP, UDP, and ICMP based attacks are detected and mitigated automatically. Coverage includes volumetric floods, protocol abuse, fragmentation attacks, and Layer 7 application attacks. Detection is based on attack methodology, not signatures.
A single rWeb instance manages all your RioRey devices across multiple sites. Multi-tenant zones, customer-facing portals, real-time traffic data, historical reporting, and a full REST API for integration with external systems.
In-line deployment
Always-on filtering at the network edge
The appliance sits directly in the traffic path. All traffic is inspected continuously. Attack traffic is dropped at line rate while legitimate traffic passes through without interruption. No operator action required to activate mitigation.
Off-ramp deployment
On-demand scrubbing via RioRey Director
Director monitors traffic via netflow and sflow. When suspicious traffic is detected it is redirected to your RioRey scrubbing devices, filtered, and returned clean. Normal traffic never touches the filtering device. Ideal for high-capacity networks where in-line deployment across all links is not practical.

Any network where in-line filtering across all links is not practical
No single-device ceiling.
RIOS filtering scales horizontally. Run multiple RE100 units in parallel to multiply scrubbing capacity. The RS40 scales by licensing additional interface pairs as you add uplinks. Start with what you need today and expand the same hardware as your network grows. For capacity beyond your edge, rCloud extends your mitigation architecture into the cloud with the same visibility and controls.
Need capacity beyond your edge?
rCloud scrubbing works alongside any RioRey appliance. Own what you regularly need. Reach into the cloud for the rest. Same rWeb visibility across both layers.
Prefer software over hardware?
rVM virtual machine filtering runs the same RIOS analytics on your existing infrastructure. Available from 1.5M PPS to 50M PPS on a subscription basis.

How do you want to deploy RioRey filtering?
In-line filtering
RioRey sits directly in the traffic path at each site. All traffic passes through the filtering device continuously. Best for always-on protection where you want immediate mitigation at the edge.
Off-ramp scrubbing
RioRey Director monitors your traffic via netflow. When suspicious traffic is detected it is redirected through your RioRey scrubbing devices. Clean traffic returns to your network. Good for high-capacity networks where in-line deployment across all links is not practical.
Your recommended configuration
This is a starting point for your conversation with the RioRey team. Exact sizing may vary based on your specific traffic profile.
Need capacity beyond your edge?
rCloud scrubbing extends your mitigation capacity on demand, with the same rWeb visibility as your on-premise devices. No black box.
