FastNetMon Alternative for
Hosting Providers

We sell Flowtriq at $9.99/node/month, so this post directly describes our product's positioning against FastNetMon for hosting use cases. All competitive pricing data comes from published vendor pages.

Why hosting providers outgrow FastNetMon

FastNetMon works well for single-tenant ISPs that monitor aggregate network traffic via NetFlow or sFlow. But hosting providers operate differently. You have dozens or hundreds of customers sharing infrastructure, each expecting individual accountability when something goes wrong. FastNetMon's architecture creates specific friction at this point.

• No per-customer visibility. FastNetMon monitors traffic at the network level using NetFlow exports from your router. It sees aggregate bandwidth and packet rates across your entire prefix block. When customer A's server gets hit with a 2 Gbps UDP flood, FastNetMon triggers a threshold alert for the whole subnet. It cannot tell you which customer is under attack without manual IP correlation, and it cannot baseline individual servers independently.
• No multi-tenant dashboard. Hosting customers expect visibility into their own protection. FastNetMon Advanced's LiveView dashboard is a single-tenant interface designed for NOC operators. You cannot give customer A a login that shows only their server's attack data while hiding customer B's traffic. There is no concept of tenant isolation, branded views, or customer-scoped API tokens.
• Dedicated server requirement. FastNetMon Advanced requires a dedicated analysis server with a minimum of 16 GB RAM, 150 GB SSD, and 8 CPU cores (per their documentation). At typical hosting prices, that is $60-$150/month in infrastructure before you pay the license. FastNetMon Community has the same hardware requirements. This is a full server that does nothing but analyze NetFlow data.
• Dashboard cost compounds quickly. FastNetMon Community has no web interface at all. Everything is CLI. FastNetMon Advanced includes basic CLI management, but the graphical dashboard (LiveView) is a separate add-on at $70/user/month. If your NOC has 3 people, that is $210/month just for dashboard access. If you want to give a customer read-only access, that is another $70/month per customer.

None of these are bugs. They are architectural decisions that make sense for a network-level ISP tool. But for hosting providers who need per-server accountability and customer-facing reporting, they become blockers.

What hosting providers actually need

Hosting customers do not care about your network topology. They care about their server. When they get attacked, they want to know what happened, when it started, what the attack vector was, and what was done about it. Your detection system needs to answer those questions per server, not per subnet.

1. Per-server detection. Each customer's server should have its own traffic baseline, its own detection thresholds, and its own attack history. A gaming server with 500 Mbps normal traffic should not share a threshold with a static website doing 2 Mbps. Per-server baselining means accurate detection regardless of what other customers on your network are doing.
2. Customer-facing attack reports. When a customer opens a ticket asking why their server was unreachable for 4 minutes, you should be able to point them to a timestamped report showing the attack vector, peak volume, duration, and mitigation action taken. This turns a support burden into a trust-building moment.
3. PCAP forensics per incident. Some attacks are not obvious from flow data alone. Customers running game servers, APIs, or financial services sometimes need packet-level evidence for their own reporting. Per-incident PCAP capture tied to a specific server and time window gives you this without storing terabytes of full-capture data.
4. Multi-channel alerting with customer isolation. Your NOC needs an alert. The customer also needs an alert. These should be configurable independently. Some customers want Discord webhooks. Some want email. Some want their own PagerDuty integration. The alerting system needs to support per-server routing without requiring your team to configure each one manually.
5. Pricing that scales with servers, not bandwidth tiers. Hosting providers add servers, not bandwidth capacity. You might add 5 new customer servers this month without any change to your upstream link capacity. Your detection cost should track the number of protected endpoints, not arbitrary bandwidth tiers that jump in $100+ increments.

How Flowtriq solves this

Flowtriq takes a fundamentally different architectural approach from FastNetMon. Instead of analyzing NetFlow data on a central server, Flowtriq deploys a lightweight agent directly on each server you want to protect. This inverts the model: detection happens at the endpoint, not the aggregation point.

Agent runs on each server. The Flowtriq agent installs in under 60 seconds (single curl command) and runs on any Linux server. Each agent builds its own traffic baseline for that specific server, detects anomalies relative to that baseline, and reports to the central dashboard. Per-customer detection is automatic because each customer's server is its own detection unit.

Dashboard shows per-server attack history. Every server has its own timeline showing detected attacks, baseline traffic, and mitigation events. You can view this per-server, per-fleet, or across your entire operation. There are no per-user fees for dashboard access. Your entire team gets access, and you can generate customer-facing reports per server.

PCAP captured per attack. When an attack is detected, the agent captures a packet sample for the duration of the event. These PCAPs are stored per server, per incident, and are downloadable from the dashboard or via API. No separate capture infrastructure required.

$9.99/node/month, no hardware. There is no dedicated analysis server to provision. No NetFlow infrastructure to configure. No bandwidth tiers. You pay $9.99 per monitored server per month. A 20-server hosting operation pays $199.80/month for complete coverage. The 14-day trial is fully featured with no credit card required.

API and webhooks for panel integration. The Flowtriq API lets you integrate attack data into your billing panel, provisioning system, or customer portal. Webhooks fire on attack start and stop events with full metadata, so you can build automated workflows (pause billing during sustained attacks, notify customers via your own channels, trigger upstream mitigation).

Migration from FastNetMon

If you are currently running FastNetMon (Community or Advanced) and want to migrate to Flowtriq, the process is straightforward and does not require downtime. You can run both systems simultaneously during the transition period to validate detection accuracy.

1. Deploy agents alongside FastNetMon. Install the Flowtriq agent on each server you want to protect. The agent operates independently and does not interfere with FastNetMon's NetFlow analysis. Both systems will detect attacks in parallel, letting you compare results.
2. Validate and tune. Run both systems for 7-14 days. Compare detection events, response times, and classification accuracy. Flowtriq's per-server baselining typically catches targeted attacks that FastNetMon misses because they fall below the network-wide threshold.
3. Decommission FastNetMon infrastructure. Once you are confident in Flowtriq's detection, remove your FastNetMon analysis server and stop NetFlow exports. You recover the dedicated server cost ($60-150/month) immediately.
