Flowtriq vs Radware DefensePro:
DDoS detection compared

Back to Blog

Understanding the Comparison

Radware DefensePro is an inline DDoS mitigation appliance that sits in the network path and uses behavioral analysis and machine learning to detect and block attack traffic in real time. Flowtriq is an agent-based detection platform that runs on individual servers to provide per-node visibility, PCAP capture, and instant alerting. These products solve different parts of the same problem.

DefensePro blocks attacks. Flowtriq sees attacks. That distinction sounds simple, but the operational implications are significant. A well-protected network needs both capabilities: something that stops the traffic at the edge, and something that tells you exactly what is happening on each server behind that edge. Neither product alone provides complete coverage.

We build Flowtriq, so our perspective is inherently biased. We will be specific about where DefensePro is the stronger product and where Flowtriq adds value that DefensePro was not designed to provide.

What Radware DefensePro Does

DefensePro is a purpose-built DDoS mitigation appliance deployed inline — typically at the network edge, in front of the servers it protects. It inspects every packet passing through it and uses Radware's behavioral analysis engine to distinguish attack traffic from legitimate traffic. When it identifies an attack, it drops or rate-limits the malicious packets while allowing clean traffic to pass through to the protected servers.

DefensePro's core strengths:

• Behavioral analysis and machine learning: DefensePro does not rely solely on static signatures or rate thresholds. It builds behavioral baselines of normal traffic patterns and detects deviations that indicate attacks. This is particularly effective against zero-day attack vectors and sophisticated multi-vector attacks that evolve during an assault.
• Inline mitigation: Because DefensePro sits in the traffic path, it can drop attack packets before they reach your servers. This is fundamentally different from detection-only products. Your servers never see the attack traffic that DefensePro filters — their CPU, memory, and network stack are protected from the load.
• Hybrid cloud integration: Radware offers DefensePro as on-premises hardware and integrates it with their cloud DDoS protection service. During volumetric attacks that exceed the on-premises appliance's capacity, traffic can be diverted to Radware's cloud scrubbing infrastructure automatically. This hybrid model provides protection against both large volumetric and smaller surgical attacks.
• SSL attack mitigation: DefensePro can decrypt and inspect SSL/TLS traffic to detect encrypted DDoS attacks — a capability that flow-based and many other detection systems lack entirely.
• Multi-vector attack handling: The behavioral engine can track and mitigate multiple simultaneous attack vectors without requiring manual intervention for each vector.
• Low latency inline processing: DefensePro is built on custom hardware and FPGAs designed for line-rate packet inspection. In normal (non-attack) conditions, the latency added to legitimate traffic is minimal — typically sub-millisecond.

Radware's DefensePro is a genuinely sophisticated product. The behavioral analysis engine is one of the best in the industry for automated mitigation decisions. For organizations that need inline protection at the network edge, DefensePro is a strong choice.

Where DefensePro Has Limitations

DefensePro's architecture creates specific gaps that are inherent to its inline-appliance design:

No per-server visibility. DefensePro protects a network segment, not individual servers. It sees traffic flowing through its interfaces, but it does not know what is happening on each server behind it. If 40 servers sit behind a DefensePro appliance and one of them is experiencing an application-layer anomaly that does not trigger DefensePro's thresholds, DefensePro has no way to detect it. It sees aggregated traffic flows, not per-server baselines.

Limited visibility into what gets through. No mitigation appliance is perfect. Sophisticated attackers deliberately craft traffic to evade behavioral analysis — low-and-slow attacks, attacks that mimic legitimate traffic patterns, or attacks that slowly ramp volume to avoid triggering anomaly thresholds. DefensePro can tell you what it blocked, but it cannot tell you what attack traffic made it through to your servers. Only something running on the server itself can provide that perspective.

No server-side PCAP. DefensePro can capture traffic at the appliance level, but it cannot capture traffic as seen by the target server after mitigation. When your team needs a PCAP of what the server actually experienced — for forensics, for understanding application impact, or for validating that mitigation rules are working correctly — DefensePro cannot provide that.

Deployment topology constraints. DefensePro must be in the traffic path to function. This works well for centralized data centers where all traffic flows through a small number of network chokepoints. It is less practical for distributed architectures with servers in multiple locations, cloud instances, edge nodes, or colocation facilities. Each location that needs protection requires its own DefensePro deployment (or Radware cloud service).

Alerting ecosystem. DefensePro's alerting integrates with Radware's management platform (APSolute Vision / Cyber Controller) and supports SNMP, syslog, and email notifications. Native integration with modern DevOps and SRE alerting tools — Slack, Discord, PagerDuty, OpsGenie — requires additional middleware or Radware's API-based integrations, which add operational overhead.

DefensePro is an excellent bouncer at the door. But it cannot tell you what is happening to each individual person inside the building. That requires visibility from inside — which is what per-server detection provides.

What Flowtriq Provides

Flowtriq runs as a lightweight agent on each Linux server. It monitors network traffic directly on the server's interface, builds per-second traffic baselines unique to that node, and detects anomalies in real time. It does not block traffic — it detects, classifies, captures PCAP evidence, and alerts your team.

The key capabilities relative to DefensePro:

• Per-server baselines: Each Flowtriq node maintains its own traffic baseline. A game server that normally handles 50,000 PPS has a different baseline than a web server handling 2,000 PPS. Anomalies are detected relative to each server's normal traffic, not a network-wide aggregate.
• Server-side perspective: Flowtriq sees exactly what traffic reaches the server — after any upstream mitigation has been applied. This means it detects attacks that get through DefensePro or any other upstream protection, providing a ground-truth view of what each server actually experiences.
• Automatic PCAP capture: Every incident includes a PCAP of the first 60 seconds of attack traffic as seen by the target server. This is invaluable for forensics, for validating upstream mitigation effectiveness, and for providing evidence to ISPs and upstream providers.
• Attack classification with confidence: Each incident is automatically classified (SYN flood, UDP flood, DNS amplification, NTP amplification, ICMP flood, HTTP flood, TCP ACK flood, multi-vector) with a confidence score. Your team gets actionable classification without manual packet analysis.
• Sub-second detection: Flowtriq detects anomalies within 1-2 seconds of onset. This complements DefensePro's inline mitigation by providing immediate alerting even when the mitigation appliance is already handling the traffic.
• Modern alerting: Native Discord, Slack, PagerDuty, OpsGenie, email, SMS, and webhook integrations. Alerts reach your team in the tools they already use, without middleware.
• Infrastructure-agnostic deployment: Works on any Linux server — bare metal, cloud, VPS, edge, colocation. No network topology changes. No inline appliance. Install the agent, connect to your dashboard, and detection starts immediately.

What Flowtriq does not do: it does not mitigate attacks. It does not drop packets. It does not sit inline. It does not inspect SSL/TLS traffic for encrypted attacks. It does not provide network-wide flow analytics. These are DefensePro's strengths.

Side-by-Side Data Comparison

Consider a scenario: a multi-vector attack targeting a single web server behind a DefensePro appliance. The attack combines a UDP flood at 300,000 PPS with a slower HTTP GET flood at 800 requests per second. DefensePro successfully mitigates 95% of the UDP flood, but the HTTP GET flood passes through because the requests individually look like legitimate traffic.

This scenario illustrates why per-server detection matters even when you have strong inline mitigation. DefensePro correctly handled the volumetric component — that is its job and it did it well. But the server-side perspective reveals residual attack traffic and an additional attack vector that the appliance did not catch. Without Flowtriq on the server, the HTTP GET flood goes undetected until it causes application-level symptoms: elevated response times, increased error rates, or eventually a service outage.

Feature-by-Feature Breakdown

• Primary function: DefensePro performs inline mitigation (detection + blocking). Flowtriq performs detection and forensics (no blocking).
• Deployment model: DefensePro is an inline hardware/virtual appliance in the network path. Flowtriq is a software agent on each server.
• Detection approach: DefensePro uses behavioral analysis and ML on traffic flowing through the appliance. Flowtriq uses per-server baseline anomaly detection on traffic reaching each node.
• Detection latency: DefensePro detects and mitigates in seconds (inline). Flowtriq detects and alerts in 1-2 seconds (agent-based).
• Mitigation: DefensePro drops/rate-limits attack packets inline. Flowtriq does not mitigate — detection and alerting only.
• Per-server visibility: DefensePro sees traffic per-network-segment. Flowtriq sees traffic per-individual-server.
• PCAP capture: DefensePro captures at the appliance. Flowtriq captures at the server (what the server actually received).
• SSL/TLS inspection: DefensePro can decrypt and inspect. Flowtriq monitors at the network layer (does not decrypt).
• Attack classification: Both classify attacks. DefensePro classifies based on behavioral patterns. Flowtriq classifies with confidence scoring and per-server context.
• Alerting: DefensePro uses Radware management platform, SNMP, syslog, email. Flowtriq uses Discord, Slack, PagerDuty, OpsGenie, email, SMS, webhooks natively.
• Deployment scope: DefensePro requires inline placement at each network segment. Flowtriq works on any server anywhere with a 5-minute install.
• Cloud/hybrid: DefensePro offers cloud scrubbing integration (Radware Cloud DDoS). Flowtriq runs on any cloud instance natively.

Pricing Comparison

Radware DefensePro pricing is not publicly listed and varies by throughput capacity, features, and deployment model. Industry pricing for DefensePro typically falls in these ranges:

• DefensePro appliance (entry-level, 2-6 Gbps): $50,000 - $120,000
• DefensePro appliance (mid-range, 10-40 Gbps): $120,000 - $350,000
• DefensePro appliance (high-end, 100+ Gbps): $400,000+
• Annual support and subscription: 18-25% of appliance cost per year
• Radware Cloud DDoS Protection: custom pricing, typically $5,000 - $30,000+/month depending on capacity
• Professional services: $20,000 - $60,000 for deployment and tuning

This is enterprise-tier pricing that reflects the hardware, R&D, and engineering that goes into an inline mitigation platform. For organizations that need inline DDoS scrubbing, this investment is justified.

Flowtriq pricing: $9.99 per node per month, or $7.99 per node per month on annual billing. 7-day free trial. No setup fees. No hardware.

• 20 servers: $199.80/month ($1,918.80/year on annual billing)
• 100 servers: $999/month ($9,588/year on annual billing)
• 500 servers: $4,995/month ($47,940/year on annual billing)

The pricing gap reflects the fundamental difference in what each product does. DefensePro is a hardware platform that actively blocks traffic at line rate. Flowtriq is a software agent that detects and reports. Inline mitigation hardware is expensive to build. Detection software is not. These are different product categories with different cost structures.

The relevant question for most teams is not "DefensePro vs Flowtriq" — it is "should we add Flowtriq for $9.99/node on top of our existing DefensePro deployment?" At that price point, the ROI calculation is straightforward: one incident where per-server PCAP data accelerates your response by even 30 minutes pays for months of Flowtriq coverage.

Hybrid Deployment: Using Both Together

The most effective architecture layers DefensePro at the network edge with Flowtriq on every server behind it. Here is how this works:

DefensePro handles inline mitigation. It continues to sit in the traffic path, inspect packets, and drop attack traffic using behavioral analysis. Volumetric floods, amplification attacks, and protocol-level attacks are caught and scrubbed before they reach your servers. This is DefensePro's purpose and it does it well.

Flowtriq handles server-side detection. The Flowtriq agent on each server monitors what traffic actually arrives after DefensePro has done its work. This provides three critical capabilities:

• Mitigation validation: Flowtriq shows you exactly what traffic is getting through DefensePro during an attack. If the residual attack traffic is still significant, you know your DefensePro rules need tuning. If it is minimal, you have confirmation that mitigation is working. Without server-side visibility, you are trusting the appliance's self-reported metrics with no independent verification.
• Application-layer coverage: Low-and-slow attacks, HTTP floods, and other application-layer attacks that DefensePro may not catch are detected by Flowtriq's per-server baselines. These attacks are designed to look like legitimate traffic at the network level but create anomalous patterns at the server level.
• Coverage for infrastructure outside DefensePro's path: Edge servers, cloud instances, remote offices, DR sites — any server not sitting behind a DefensePro appliance gets detection coverage through Flowtriq's agent. No additional hardware deployment required.
• Forensic evidence: Server-side PCAP captures provide ground-truth data about what the server experienced. This is invaluable for post-incident analysis, customer reporting, and improving DefensePro's behavioral rules.
• Parallel alerting: Even when DefensePro is mitigating successfully, Flowtriq can alert your team that an attack is in progress, providing real-time awareness through the channels your team actually monitors (Slack, Discord, PagerDuty).

The two products do not conflict operationally. DefensePro inspects and filters traffic inline. Flowtriq observes traffic passively on the server. They share no configuration, no infrastructure dependencies, and no resource contention. Running both is additive, not duplicative.

When to Use Each

Use DefensePro (without Flowtriq) when:

• Your primary need is inline mitigation — you need to actively block DDoS traffic before it reaches your servers.
• All your protected infrastructure sits behind DefensePro appliances and you do not need per-server-level visibility.
• Your team has the operational maturity and tooling to extract server-level insights from DefensePro's reporting and does not need an additional detection layer.
• SSL/TLS attack inspection is a primary requirement and you need the appliance to decrypt and analyze encrypted traffic.

Add Flowtriq alongside DefensePro when:

• You need to validate that DefensePro's mitigation is actually effective — per-server visibility shows what traffic gets through.
• You have servers in locations not covered by DefensePro (cloud, edge, colocation, DR sites).
• Application-layer attacks are a concern and you want per-server detection of traffic patterns that look normal at the network edge.
• Your incident response process requires PCAP evidence from the target server's perspective.
• Your team needs alerting in Slack, Discord, PagerDuty, or OpsGenie without building custom integrations on top of DefensePro's SNMP/syslog output.
• You want per-server per-second traffic analytics and historical baselines for capacity planning and anomaly investigation.

Use Flowtriq without DefensePro when:

• You do not have the budget for inline mitigation hardware. Flowtriq provides detection, classification, and forensics at $9.99/node/month — giving you the visibility to respond manually or trigger upstream mitigation.
• Your mitigation strategy relies on upstream providers (transit provider scrubbing, Cloudflare, AWS Shield) and you need server-side detection to monitor what gets through.
• You are a cloud-native organization without physical network infrastructure where you could deploy inline appliances.
• Your primary need is detection and alerting rather than active inline blocking.

The Honest Summary

Radware DefensePro is one of the strongest inline DDoS mitigation platforms available. Its behavioral analysis engine, ML-based detection, SSL inspection capabilities, and hybrid cloud integration make it a compelling choice for organizations that need active DDoS scrubbing at the network edge. If your primary requirement is "stop DDoS traffic from reaching our servers," DefensePro does that job well.

Flowtriq is a per-server detection and forensics platform. It does not compete with DefensePro's mitigation capabilities. Instead, it provides the server-side visibility layer that inline appliances cannot: per-node baselines, server-perspective PCAP captures, sub-second alerting through modern channels, and detection of traffic that passes through upstream protection.

The strongest security posture uses both: DefensePro at the edge to block attacks, and Flowtriq on every server to verify mitigation effectiveness, catch what gets through, and provide the forensic data your team needs for response and analysis. At $9.99/node/month, adding Flowtriq behind your DefensePro deployment is one of the highest-ROI investments you can make in DDoS visibility.
