Attacks get blocked in your network—before they reach applications, before customers notice, before they damage your business. Sub-second inline mitigation protects revenue, reputation, customer trust, and regulatory compliance.
Mixed traffic flow
Revenue, reputation, trust secured
Combine on-premises protection with cloud scrubbing for seamless hybrid deployment. Get the best of both worlds.
On-premises DDoS protection deploys inline at your network edge, analyzing and filtering traffic in real-time before it reaches your applications. Unlike cloud-based solutions that redirect traffic through external scrubbing centers, on-premise protection operates directly within your infrastructure—eliminating latency penalties and maintaining complete data sovereignty.
The key advantage is response time. Traditional flow-based detection systems analyze aggregated traffic patterns and can take several minutes to identify and respond to attacks. In contrast, inline packet-level inspection enables behavioral threat detection on the first few packets—achieving sub-second mitigation that prevents service degradation before customers are affected.
This approach is particularly valuable for organizations with strict compliance requirements, performance-critical applications, or data residency mandates where traffic must remain within controlled infrastructure. SmartWall ONE delivers line-rate inspection up to 800 Gbps with less than 1ms latency, ensuring protection doesn't compromise performance.
Every packet is analyzed at line rate as it enters your network, enabling immediate threat identification.
Machine learning identifies anomalous patterns in the first packets—not after minutes of flow aggregation.
Surgical filtering removes malicious traffic while legitimate requests flow uninterrupted—no manual intervention required.
Sub-millisecond latency maintains application performance even during active attack mitigation.
Detection and mitigation speed directly impacts service availability and customer experience
Attacks identified and blocked within one second—before customers notice, before services degrade
Behavioral analysis on first packets
Inline blocking at line rate
SmartWall ONE sits directly in your network path—not analyzing copies of traffic, not waiting in the cloud. Every packet gets inspected at line rate as it arrives, with sub-microsecond latency that doesn't slow legitimate traffic.
Attacks announce themselves through behavior. SYN floods don't look like legitimate connections—they look like machine guns. HTTP floods don't browse like real people. The behavioral analysis engine spots these patterns instantly in the first few packets and blocks them.
Layers 3, 4, and 7 attacks all get stopped by the same platform. Volumetric floods, protocol abuse, encrypted application attacks, bot traffic—all handled without managing multiple security tools or piecing together different vendors' telemetry.
SecureWatch Analytics orchestrates policies across all your SmartWall ONE deployments. Configure protection rules once; they enforce everywhere. If a data center goes offline, protection automatically stays active at your other sites.
Deploy in your data center on your terms. Get sub-second mitigation without sending traffic to the cloud or waiting for manual intervention.
No more 2 AM calls. Attacks get blocked automatically while your team monitors dashboards—not fighting fires.
Here's what changes: you stop getting emergency calls about attacks. You stop scrambling to redirect traffic. You stop explaining why services were down.
SmartWall ONE runs automatically. After learning your traffic patterns (about 48 hours), it just works. Attacks get blocked. Clean traffic flows through. Your team reviews reports in the morning instead of fighting fires all night.
Your security team focuses on strategic initiatives instead of reactive firefighting. Nobody needs to be on-call specifically for attack mitigation.
Run on our appliances or your existing Dell, HPE, or SuperMicro servers. Your hardware, your choice.
Most vendors lock you into their specific appliances. Then you're stuck with their hardware refresh cycles, their pricing, their supply chain. Need protection in Brazil or Singapore? Good luck waiting months for specialized equipment.
We do sell appliances—they're excellent if that's what you want. But we also run on Dell, HPE, or SuperMicro servers you already own or can source locally. Same software, same protection.
Stop juggling multiple security tools. One interface, one log format, one vendor relationship.
Count how many tools your team uses for DDoS defense right now. Firewall for some stuff. WAF for application protection. Maybe cloud scrubbing for volumetric attacks. Flow monitoring for visibility. Each one has its own interface, log format, and management overhead.
SmartWall ONE handles network-layer volumetric floods, protocol attacks, encrypted HTTPS floods, application-layer exploits, and bot traffic. When attacks hit multiple layers simultaneously (they usually do), you see the whole attack in one view.
Training gets simpler. Troubleshooting gets faster. Budget discussions get cleaner. Better signal-to-noise ratio means no more alert fatigue.
Get continuous intelligence on your network—attack or not. Make better infrastructure decisions with real data.
Most DDoS tools only give you visibility during attacks. CORE Traffic Analysis runs continuously, showing which applications consume bandwidth, which customers generate which traffic types, where your transit costs actually go.
This turns out to be incredibly valuable for business decisions that have nothing to do with security:
Organizations that can't afford latency, need compliance control, or run their own infrastructure
Financial services, healthcare, government, and regulated industries
Your CIO wants uptime metrics. Your CFO questions security budgets. Compliance needs proof that data never leaves your infrastructure. And when attacks hit, you're choosing between routing to scrubbing services (10+ minutes, compliance issues) or hoping your firewall holds up.
Either way, applications experience downtime.
ISPs, hosting companies, MSPs, and colocation providers
Your customers expect 100% uptime. Your SLAs promise it. But you're either absorbing attacks with your infrastructure (expensive, risky) or routing to third-party scrubbing (customers notice and complain).
Managing per-customer policies across hundreds of accounts sounds like a nightmare.
B2B platforms, developer tools, and mission-critical applications
Every minute of downtime directly impacts revenue and retention. Your support team drowns during outages. Your lean infrastructure team can't handle constant DDoS firefighting.
Cloud scrubbing introduces latency your customers feel. You need millisecond response, not seconds.
Global enterprises with distributed data centers and redundant infrastructure
You've invested in infrastructure redundancy—multiple data centers, geographic distribution, failover capabilities. But DDoS protection is still a single point of failure.
If your defense data center goes dark, you're exposed until manual reconfiguration.
The technical foundation your infrastructure and security teams need to validate this actually delivers
SmartWall ONE sits directly in the network path between internet edge and protected infrastructure. All traffic flows through at line rate with sub-microsecond latency.
For selective protection or asymmetric routing architectures. BGP-integrated scrubbing where clean traffic flows normally while suspicious traffic routes through for inspection.
Purpose-built Corero appliances optimized for DDoS protection workloads with zero-power bypass interfaces.
Run SmartWall ONE on approved bare metal servers or virtualized environments. Same protection, your hardware choice.
On-prem handles 95%+ of attacks. For rare volumetric floods that exceed your bandwidth, traffic automatically swings to cloud scrubbing via Akamai or your preferred provider. Pay only when you need it.
Every DDoS solution claims to stop attacks. The question is: how fast, at what cost to your performance, and with how much operational overhead?
The differences come down to architecture. Where the defense sits, how it processes traffic, whether it can respond before damage occurs—these determine whether your services stay online or go down during attacks.
Redirect-based solutions take 5-15 minutes to activate. During those minutes, your services are down. Inline protection means the defense is already in place when attacks arrive. They get blocked immediately, not eventually.
Volume-based detection triggers on traffic spikes—your marketing campaign can trigger false alarms while sophisticated attacks slip through. Behavioral analysis looks at what traffic is trying to do, not just how much there is.
Most solutions decrypt all HTTPS traffic in a single queue. Under attack, that queue becomes the bottleneck—the defense itself becomes the performance problem. Parallel architecture means the DDoS engine runs at full speed while selective decryption happens separately.
Managing separate tools for network DDoS, application protection, and traffic analysis means three different interfaces and three different vendors. One platform handling everything means clearer visibility, simpler troubleshooting, and fewer vendors to manage.
