We sell Flowtriq at $9.99/node/month, so we have an obvious interest in this conversation. That said, every pricing figure cited here comes from published vendor pages, public documentation, and conversations with operators who shared their quotes with us. We will be transparent about what we know and what we are estimating.
The CapEx model that built the industry
The DDoS protection market was born in the early 2000s, during an era when security meant hardware. Firewalls were appliances. Intrusion detection meant physical sensors. DDoS protection followed the same playbook: buy a box, rack it, and pay annual maintenance to keep it running.
That model made sense when networks were simpler. You had a defined perimeter, a handful of uplinks, and traffic volumes measured in single-digit gigabits. A $50K appliance could sit on your transit edge, inspect every packet, and handle your entire DDoS detection and mitigation workflow from one chassis.
Twenty years later, the networks have changed dramatically, but the pricing model has barely moved. The same vendors still sell the same boxes, just with bigger throughput ratings and higher price tags. The fundamental structure of "buy hardware up front, pay annual support, hire experts to run it" persists across the major vendors.
What you actually pay for an appliance-based solution
The sticker price is just the beginning. Here is what a typical enterprise DDoS deployment actually costs when you add up all the components:
Arbor Networks (now NETSCOUT)
Arbor has been the market leader in carrier-grade DDoS detection since the mid-2000s. Their Sightline/TMS combination is deployed by most Tier 1 ISPs globally. The pricing reflects that positioning:
- Sightline (detection/visibility): $80K-$200K depending on the deployment size and throughput license
- TMS (mitigation appliance): $100K-$400K per unit, with larger networks needing multiple units
- Annual support and subscription: 18-22% of the hardware cost per year, so $30K-$130K annually
- Professional services for deployment: $15K-$50K for initial setup and tuning
- Rack space and power: 2-4U per appliance, $200-$600/month in colocation costs
A mid-size ISP deploying Arbor Sightline with a single TMS is looking at $200K-$350K in the first year, with $50K-$130K in recurring annual costs. For a carrier with 100 Gbps+ of transit capacity and millions in monthly revenue, that is a line item. For a 50-server hosting provider, it is more than their annual infrastructure budget.
Radware DefensePro
Radware positions DefensePro as a behavioral-based DDoS protection appliance. Their pricing follows a similar pattern:
- DefensePro appliance: $40K-$250K depending on throughput (from 6 Gbps to 400 Gbps models)
- Annual subscription (ERT, signatures): $10K-$60K per year for Emergency Response Team access and attack signature updates
- Cloud DDoS service (hybrid): $3K-$15K/month for cloud scrubbing capacity
- Professional services: $10K-$30K for initial deployment and policy tuning
Radware's hybrid model (on-prem appliance + cloud scrubbing) is more modern than pure CapEx, but the on-prem component still anchors the pricing in hardware territory. You are buying an appliance first, then paying for cloud capacity on top.
FortiDDoS (Fortinet)
Fortinet's DDoS product sits within their broader Security Fabric ecosystem. Pricing is more accessible than Arbor or Radware, but still hardware-first:
- FortiDDoS appliance: $30K-$150K depending on throughput model
- FortiCare support: $5K-$25K annually
- FortiGuard subscription: $3K-$15K annually for threat intelligence updates
FortiDDoS benefits from Fortinet's massive channel, so discounts are common. But the model is identical: hardware purchase, annual support, annual subscriptions. And because Fortinet's value proposition is the Security Fabric integration, you get the most value when you are already running FortiGate firewalls, FortiSIEM, and FortiAnalyzer. If you are not in the Fortinet ecosystem, you are paying a premium for integration capabilities you will never use.
Corero SmartWall
Corero markets SmartWall as an always-on, automatic DDoS protection appliance with sub-second mitigation. Their approach is to sit inline at your network edge and scrub traffic in real time:
- SmartWall appliance: $60K-$200K per unit
- Annual maintenance: 15-20% of hardware cost per year
- SmartWall SecureWatch (analytics): Additional license fees for the analytics and reporting platform
Corero's model works well for operators who want inline, always-on mitigation with no human intervention. But the price point excludes most of the market outside of large ISPs and data center operators.
The hidden costs nobody talks about
Beyond the sticker price, appliance-based DDoS tools carry costs that rarely appear in the initial quote:
Expertise. Every appliance vendor assumes you have staff who know how to operate their system. Arbor assumes you have NOC engineers who understand flow telemetry, BGP signaling, and mitigation policies. Radware assumes someone can tune behavioral policies. FortiDDoS assumes Fortinet-certified engineers. These are specialized skills, and hiring for them costs $120K-$180K per year per engineer in North America.
Ongoing tuning. Static configurations trigger false positives. Traffic patterns change. New attack vectors emerge. Every appliance needs periodic tuning, which means either in-house expertise or recurring professional services engagements at $200-$400/hour.
Hardware refresh cycles. Appliances have a useful life of 3-5 years before they fall behind on throughput requirements and lose vendor support. That $200K Arbor deployment? You will be buying a replacement in 2029, plus paying to migrate your configuration and retrain your team on the new platform.
Opportunity cost of rack space. In a colocation facility, every rack unit has a monthly cost. A 2U DDoS appliance in a prime colo facility costs $200-$600/month in space and power alone. Over a 4-year deployment, that is $10K-$30K in rack costs for a device that mostly sits idle between attacks.
"We were quoted $180K for the hardware, plus $40K/year in support. When I added up the server, the rack space, the training for my two engineers, and the professional services for initial tuning, the first-year cost was closer to $280K. For a 30-server hosting operation, that was not happening."
That quote came from a hosting provider who contacted us after pricing Arbor Sightline/TMS for their network. Their experience is not unusual. The enterprise DDoS market was built for enterprises, and the pricing reflects it.
Why the pricing has not come down
There are structural reasons why appliance pricing stays high, and they are not all about vendor greed:
R&D costs are real. Building hardware that can inspect packets at 100 Gbps+ line rate requires custom ASICs or high-performance FPGAs. The silicon development alone costs millions. These costs get amortized across a relatively small customer base (there are only so many Tier 1 ISPs), which keeps per-unit pricing high.
Certification and compliance. Appliance vendors maintain FCC, CE, and various carrier certifications for their hardware. Each hardware revision requires re-certification. This is a cost that pure software solutions do not carry.
Channel margins. Most enterprise DDoS sales go through VARs (Value Added Resellers) and distributors. The vendor, the distributor, and the VAR each take a margin. By the time the product reaches the end customer, 30-50% of the price is channel margin.
Installed base inertia. Existing customers on annual support contracts represent recurring revenue. Vendors have little incentive to cannibalize that revenue by offering cheaper alternatives. If Arbor launched a $500/month SaaS product that could replace a $200K Sightline deployment, they would be undermining their own installed base.
None of this means the pricing is justified for the buyer. It just means the pricing is not going to change from within the incumbent vendor ecosystem. Change comes from outside.
The SaaS/OpEx alternative
The shift from CapEx to OpEx is not new in infrastructure. Monitoring moved to SaaS years ago (Datadog, New Relic). Logging moved to SaaS (Splunk Cloud, Elastic Cloud). Security tools like SIEM have moved to SaaS (Sumo Logic, Sentinel). DDoS protection is one of the last categories still dominated by hardware-first pricing.
The SaaS model changes the economics fundamentally:
- No upfront hardware cost. Your first month costs the same as your twelfth month. There is no capital approval process, no procurement cycle, no depreciation schedule.
- No hardware refresh. Software updates are continuous. You do not buy a new box every 4 years. The vendor upgrades the detection engine, the dashboard, and the integrations without any hardware change on your end.
- No rack space. Software agents run on your existing infrastructure. No additional rack units, no additional power draw, no additional cross-connects.
- Predictable scaling. Adding capacity means adding nodes, not negotiating a new throughput license. Your costs grow linearly with your infrastructure, not in staircase steps at tier boundaries.
- No expertise premium. Well-designed SaaS tools handle the tuning automatically. Adaptive baselines replace manual policy configuration. Web dashboards replace CLI expertise requirements.
The trade-off is clear: SaaS DDoS tools do not sit inline and scrub packets at line rate. If you need a device that can drop 100 Gbps of attack traffic while forwarding clean traffic at wire speed, you still need hardware. But most operators do not need that. They need to know when an attack starts, what kind of attack it is, and have it stopped within seconds. That is a software problem, not a hardware problem.

Start Free Trial →How Flowtriq approaches pricing differently
We price Flowtriq at $9.99 per node per month. That is the entire pricing model. There are no tiers, no add-ons, no per-user dashboard fees, no throughput licenses.
What that means in practice:
| Infrastructure size | Monthly cost | Comparable appliance cost (Year 1) |
|---|---|---|
| 10 servers | $99.90/month | $50K-$100K |
| 50 servers | $499.50/month | $100K-$200K |
| 100 servers | $999/month | $150K-$350K |
| 500 servers | $4,995/month | $300K-$500K+ |
The comparison is not perfectly apples-to-apples. An Arbor TMS provides inline scrubbing that Flowtriq does not. A Corero SmartWall drops malicious packets at wire speed. These are capabilities that have real value for operators who need them. But most operators who are pricing Arbor or Corero discover they need detection and alerting first, and scrubbing second, and the detection component alone does not require a $200K appliance.
What $9.99/node includes:
- Real-time attack detection (1-2 seconds to identify)
- Automatic attack classification across all major DDoS vectors
- Per-node adaptive baselines that learn each server's normal traffic patterns
- PCAP capture on every detected attack for forensics and compliance
- Multi-channel alerting (Slack, Discord, PagerDuty, OpsGenie, email, SMS, webhooks)
- BGP integration for RTBH and FlowSpec mitigation
- Full web dashboard with unlimited users and no per-seat fees
- REST API for integration with existing tooling
- Unlimited support, no ticket caps
We do not charge for PCAP storage, dashboard access, or support tiers. The model is deliberately simple because complicated pricing models are one of the reasons operators avoid buying DDoS protection in the first place.
When the appliance model still makes sense
We would be dishonest if we said appliances are never the right choice. There are specific scenarios where hardware-based DDoS protection is worth the cost:
Inline scrubbing at scale. If you operate a 100 Gbps+ transit network and need to scrub traffic at line rate without adding latency, you need purpose-built hardware. No software agent can match the packet-per-second performance of a dedicated ASIC-based scrubbing appliance.
Regulatory requirements. Some regulated industries require on-premise security controls. If your compliance framework mandates that DDoS protection hardware is physically located in your facility, a SaaS agent may not satisfy the auditor.
Existing Arbor/Radware ecosystems. If you already have Arbor Sightline deployed across a multi-site carrier network with trained staff and established processes, the marginal cost of adding another TMS is lower than the cost of migrating your entire workflow to a new platform.
For everyone else, and that includes most hosting providers, ISPs under 100 Gbps, data center operators, and managed service providers, the question is whether $50K-500K in hardware is the best use of that budget when SaaS alternatives provide detection, alerting, and mitigation triggering at a fraction of the cost.
The market is shifting
We are not the only ones who see this. The DDoS protection market is gradually moving away from pure CapEx. Radware launched a cloud-first offering. Arbor (NETSCOUT) introduced cloud-based Arbor Cloud. Even Fortinet is pushing FortiDDoS-F as a managed service option. The incumbents see the writing on the wall, but they are constrained by their existing revenue models and channel relationships.
For operators evaluating DDoS protection today, the key question is no longer "can we afford protection?" It is "are we paying 10-100x more than we need to for the detection and mitigation capabilities we actually use?"
In most cases, the answer is yes.
