DDoS detection and mitigation without the six-figure price tag
NETSCOUT Arbor Sightline + TMS deployments start at $250K+ and take months to go live. Flowtriq deploys on any Linux server in 5 minutes, detects attacks in 1-2 seconds, and auto-escalates mitigation, all at $9.99/node/month.
The cost gap
What an Arbor deployment actually costs
Arbor is the industry standard for carrier-grade DDoS protection. It is also priced like one. Here is what a typical Sightline + TMS deployment looks like financially.
What Arbor users actually say
Real complaints from verified Arbor customers
These are sourced from peer review platforms. We have not altered the quotes, only censored names and companies for privacy.
Pricing that locks out most operators
A full Arbor deployment (Sightline + TMS + AED) easily crosses $250K in the first year, with annual support running 15-20% of hardware cost on top. That pricing model assumes carrier-scale budgets.
Support quality declined after acquisition
Arbor Networks was acquired by NETSCOUT in 2015. Since then, multiple customers have reported slower response times, less specialized expertise, and a general sense that DDoS is no longer the company's sole focus.
The management console feels dated
Arbor's Sightline interface has not kept pace with modern dashboard expectations. Operators who spend hours a day in the console notice the gap, especially those who have used more recent network monitoring tools.
False positives block legitimate traffic
Arbor's threshold-based detection at the network aggregate level can misidentify legitimate traffic spikes as attacks, especially for individual servers with traffic patterns that deviate from the broader baseline.
Reporting lacks depth
Multiple Arbor users report that the built-in reporting does not provide enough granularity, particularly for operators who need per-customer or per-server attack breakdowns for SLA documentation or downstream communication.
Closed mitigation ecosystem
Arbor's TMS scrubbing integrates tightly with Sightline, but coordinating mitigation with third-party scrubbing providers or external systems requires workarounds. Operators using mixed vendor environments feel this limitation.
Attack data disappears quickly
Short-lived attacks are difficult to investigate after the fact. Once an attack ends, the forensic data needed to understand what happened may already be gone from the console, making post-incident analysis harder.
Upgrades are complex and risky
Arbor's upgrade process for Sightline and TMS can introduce instability. With a multi-appliance deployment, coordinating upgrades across components adds significant operational overhead and risk.
Side-by-side comparison
NETSCOUT Arbor vs Flowtriq
A factual comparison across detection, mitigation, deployment, integrations, and pricing.

Who each tool serves
Different tools for different scales
Arbor and Flowtriq serve different segments of the market. The right choice depends on your scale, budget, and operational model.
Flowtriq works well for
Hosting providers, ISPs, game server operators, cloud-hosted infrastructure, organizations that need detection and mitigation without six-figure hardware investments, operators who want per-server visibility and PCAP forensics, teams using upstream cloud scrubbing or BGP-based mitigation, and anyone who wants to be live in 5 minutes rather than 5 months.
Arbor works well for
Tier-1 carriers and large ISPs that need on-premise volumetric scrubbing at hundreds of Gbps, organizations that require ATLAS global threat intelligence, enterprises with established NETSCOUT relationships and dedicated network security teams, and operators where carrier-grade TMS scrubbing and decades of institutional trust are hard requirements.
Use both together
The strongest deployment layers Arbor at the network level for flow-based detection and TMS scrubbing, with Flowtriq agents on servers for per-node visibility. Arbor handles network-wide flow analysis and volumetric mitigation. Flowtriq adds per-server baselines, below-threshold attack detection, server-side PCAP, and modern alert integrations that Sightline's native alerting does not cover.
Flowtriq as Arbor alternative
If you do not operate at carrier scale and your mitigation relies on upstream scrubbing, BGP RTBH, or FlowSpec rather than on-premise TMS hardware, Flowtriq provides faster detection (1-2 seconds vs flow collection intervals), per-server granularity, 4-tier auto-mitigation escalation, and modern integrations at roughly 1/100th the cost of a full Arbor deployment.
