Game server hosting is attacked more frequently than almost any other hosting category. The combination of competitive player communities, easily identifiable server IPs, and the immediate visible impact of latency spikes makes game servers an attractive DDoS target. A 200ms latency spike during a critical game moment is enough to generate player complaints; a 30-second attack that triggers a blackhole route and takes the server offline entirely is a refund request and a chargeback.
The requirements for game hosting DDoS protection are fundamentally different from web hosting or enterprise networks. Detection tools designed for general network monitoring were not built with these constraints in mind. This guide covers what actually matters for game hosting operators and compares five tools across those specific requirements.
Why game server hosting has unique DDoS requirements
The challenge with game server DDoS protection is not primarily about scale. Most game server attacks are under 10 Gbps. The challenge is the interaction between attack response time and the latency sensitivity of the application:
- Latency tolerance is measured in milliseconds: Most game protocols have a functional latency window of 20-100ms. Any scrubbing or re-routing that adds more than a few milliseconds of round-trip latency is noticeable to players. BGP-based scrubbing center diversion, which can add 20-50ms of routing overhead, is often worse for players than the attack itself if the attack is sub-threshold.
- UDP is the dominant protocol: Game server protocols use UDP almost universally, from Minecraft and Valve game servers to custom UDP-based game engines. UDP flood attacks, DNS amplification (targeting UDP/53), and NTP amplification (targeting UDP/123) are the most common attack vectors. Detection tools that excel at TCP SYN flood detection but treat all UDP traffic as equivalent provide limited value.
- Volumetric AND application-layer attacks: Game servers face both volumetric UDP floods and targeted application-layer attacks that exploit game protocol parsing. A tool that only detects volumetric thresholds will miss slow-rate game protocol exhaustion attacks that are specifically designed to stay under bandwidth thresholds.
- Player complaints are the detection mechanism of last resort: If your monitoring tool doesn't detect an attack until players have already been experiencing latency for 60 seconds, the damage is done. Sub-second detection is not an engineering nicety; it is the difference between transparent mitigation and visible service degradation.
- Blackhole routing destroys the server: The default automated response of many network-level DDoS tools is to blackhole the attacked IP. For a game server, this is operationally equivalent to a successful attack. The server is unreachable and players are disconnected. Targeted mitigation that keeps the server online while dropping attack traffic is a non-negotiable requirement.
What game hosting operators need from a detection tool
- Sub-second detection latency to enable mitigation before players notice
- UDP flood classification that distinguishes flood types (amplification, random-source flood, protocol-specific)
- Per-server granularity so an attack on one server does not degrade detection fidelity on neighbors
- Attack-specific mitigation signals (not just "attack detected") to enable targeted filtering
- Low false positive rates: triggering mitigation on legitimate traffic spikes during peak player hours is a real operational cost
- PCAP forensics for post-attack analysis and upstream abuse reporting
The five tools compared
1. Flowtriq
Flowtriq deploys a lightweight agent directly on each game server. The agent monitors the server's network interface at per-second granularity, tracking packets per second, bandwidth, connection states, and protocol distribution. Because detection happens at the server rather than at a network sampling point, there is no flow export delay and no sampling error: the agent detects the attack as it begins.
UDP flood detection: Flowtriq classifies UDP flood attacks by sub-type: random-source UDP floods, DNS amplification (source port 53 with spoofed sources), NTP amplification (source port 123), and SSDP amplification (source port 1900). The classification is automatic and does not require manual rule configuration. Each attack incident includes peak PPS, peak bandwidth, estimated source count, and PCAP evidence.
Detection speed: Approximately 1 second. Because the agent monitors at per-second intervals on the server's own interface, the detection latency is the time it takes for the traffic pattern to deviate from baseline, typically within the first second of an attack. This is fast enough to trigger mitigation before most players experience visible latency.
Per-server granularity: Each Flowtriq agent is independent. An attack on Game Server A generates an alert for Game Server A. Servers B through Z continue reporting their own traffic independently. There is no aggregate threshold that gets confused by simultaneous legitimate traffic spikes on neighboring servers.
PCAP forensics: The agent automatically captures the first 60 seconds of attack traffic as a PCAP file, downloadable from the dashboard. This is the only tool in this comparison that provides automatic packet-level forensic evidence. PCAPs are essential for upstream abuse reports, and for identifying when attackers change their source IP pools or attack vectors.
Mitigation integration: Flowtriq fires a structured webhook on attack detection, which your mitigation infrastructure uses to trigger targeted filtering rules. The webhook payload includes the attack classification and target IP, so firewall rules or upstream filter rules can be applied selectively to the attack traffic rather than blocking all traffic to the server.
Pricing: $9.99/node/month (monthly), $7.99/node/month (annual). 7-day free trial, no credit card required. A 20-server game hosting operation runs $160/month on the annual plan.
2. Corero SmartWall
Corero SmartWall is an inline hardware DDoS mitigation appliance deployed at the network edge of a data center or colocation facility. It processes traffic at line rate (up to 100Gbps per appliance) with extremely low added latency (sub-microsecond for non-attack traffic). SmartWall applies mitigation automatically at L3/L4 without requiring traffic diversion to a scrubbing center.
Strengths for game hosting: The latency overhead is genuinely minimal. Because SmartWall processes traffic inline in hardware, clean traffic passes through with negligible added latency. For colocation data centers and large hosting operators with dedicated hardware infrastructure, this is the best option for transparent mitigation that does not degrade player experience.
UDP flood protection: SmartWall's hardware offload handles high-rate UDP floods effectively at line rate. The appliance can apply challenge-response mechanisms and rate limiting per source IP without impacting throughput for legitimate traffic.
Limitations: Corero SmartWall is a significant capital expenditure, typically $30,000 to $150,000+ per appliance depending on throughput capacity and feature licensing. It requires hardware installation at a colocation or data center facility: it cannot be deployed on a per-server basis or in cloud environments. Ongoing support contracts add to total cost of ownership. This makes it appropriate for hosting operators managing large infrastructure footprints, not individual game server operators.
Best for: Colocation and dedicated hosting operators managing dozens to hundreds of game servers in owned or leased data center space, where the CAPEX investment amortizes across a large customer base.
3. Path.net
Path.net is a DDoS protection network with a focus on game server and hosting use cases. It uses anycast routing to absorb and scrub attack traffic at multiple PoPs before delivering clean traffic to your server. Path.net has built specific game protocol support and is well-regarded in Minecraft and general game hosting communities.
Strengths: Path.net's scrubbing network is specifically tuned for game protocols, with filtering rules designed for Minecraft, Source engine, and other common game server traffic patterns. The network capacity is substantial enough to absorb large volumetric attacks without the protected server seeing saturated bandwidth. Setup is straightforward: announce your server's IP through Path.net's BGP infrastructure and traffic is automatically proxied through their scrubbing network.
Latency consideration: Any scrubbing-network approach adds latency based on routing path. Path.net's anycast architecture routes traffic to the nearest scrubbing PoP, which minimizes added latency for most deployments, but players in regions without a nearby PoP may see 10-30ms additional latency compared to direct routing. For latency-sensitive competitive game servers, this is worth testing in your target player region before committing.
Limitations: Path.net is primarily a mitigation service rather than a detection tool. It does not provide per-server attack classification, PCAP forensics, or detection signals for your own monitoring infrastructure. Pricing at the scale of a large game hosting operation (many protected IPs) can become substantial.
Best for: Individual game server operators or small hosting companies that want full-service DDoS protection without managing mitigation infrastructure, particularly in regions well-covered by Path.net's PoP network.
4. Voxility
Voxility provides BGP-based DDoS scrubbing and mitigation for hosting providers. It operates as a transit provider with built-in scrubbing infrastructure: you peer with Voxility via BGP, and attack traffic is scrubbed before being delivered to your network. Alternatively, you can use a GRE tunnel overlay without full BGP peering.
Strengths: Voxility's scrubbing capacity is substantial and their network is specifically designed for hosting provider use cases. They have established peering relationships globally and are a practical option for hosting operators who want to replace their upstream transit with an attack-aware transit provider.
Game hosting use: Voxility is used by hosting providers that serve game server customers. It handles high-rate UDP floods effectively at the network level. However, it operates at the hosting provider layer rather than the per-server layer: individual game servers do not get per-server visibility into which attacks are occurring or what type they are.
Limitations: Voxility requires BGP peering or GRE tunnel setup, which adds infrastructure complexity compared to agent-based or proxy-based approaches. Pricing requires a direct engagement with Voxility's sales team and is typically scoped to bandwidth commitments. Detection signals and forensic data at the per-server level are not part of the offering.
Best for: Mid-to-large game hosting operators who want to replace upstream transit with scrubbing-aware transit and have the network engineering capacity to manage BGP peering relationships.
5. TCPShield
TCPShield is a reverse proxy service specifically designed for Minecraft and Java-based game servers. It proxies TCP connections through its network, providing L7 DDoS protection by filtering out bot connections and application-layer attacks before they reach the game server. It is well-known in the Minecraft hosting community and offers a free tier for smaller deployments.
Strengths: TCPShield's L7 filtering is purpose-built for Minecraft protocol, which means it can distinguish legitimate Minecraft client connections from bots and floods with game-protocol-level precision. The free tier makes it accessible for individual server operators. Setup is simple: change your DNS to point to TCPShield's network.
Limitations: TCPShield only protects TCP-based applications. It provides no protection for UDP traffic, which means it cannot protect servers running UDP-based game protocols (most non-Minecraft game engines). It is also purely L7: volumetric UDP floods that do not reach the proxy layer are not mitigated. It does not provide attack detection signals, PCAP forensics, or per-server visibility into attack traffic composition. It is a specialized tool for a specific use case (Minecraft TCP L7 protection) rather than a general-purpose DDoS detection or mitigation platform.
Best for: Minecraft server operators who primarily face bot-based and application-layer connection floods and want a simple, low-cost proxy-based protection solution.

Why node-level detection matters for gaming
The single most important difference between Flowtriq and the other tools in this comparison is where detection happens. Every network-level scrubbing solution in this list operates at or above the infrastructure layer: traffic is absorbed, filtered, or blackholed before it reaches your server. This creates two fundamental problems for game hosting:
Latency preservation requires knowing what you are fighting. Targeted mitigation that drops only attack packets requires knowing the attack type, source IP patterns, and traffic signature before applying filtering rules. A tool that reports "UDP flood detected, 50 Gbps" is less actionable than one that reports "DNS amplification attack, source port 53, estimated 15,000 spoofed sources, peak 50 Gbps, PCAP attached." The second report lets you apply a specific upstream ACL that blocks UDP/53 while allowing legitimate game traffic. The first report gives you a choice between blackhole (server offline) and nothing.
Per-server granularity prevents collateral damage. When a network-level solution detects an attack against one server, it typically applies mitigation at the IP level. If your game servers share a /24 or a shared upstream link, the mitigation can affect neighboring servers. Flowtriq's per-agent architecture means each server reports its own attack independently. A flood against Server A does not affect Server B's detection or trigger false-positive mitigation on Server B's traffic.
The game hosting operators who get the best outcomes combine two things: fast detection with classification (to know what is happening immediately), and targeted mitigation infrastructure (to respond without dropping clean traffic). Flowtriq covers the detection side; your network infrastructure covers the mitigation side.

Does Flowtriq work for Minecraft servers?
Yes. Flowtriq works on any Linux server, including servers running Minecraft (Java or Bedrock), Forge, Paper, Spigot, and other JVM-based Minecraft variants. The agent monitors the server's network interface and classifies attacks based on traffic patterns rather than application protocol, so it works regardless of which game server software you run. For Minecraft specifically, Flowtriq detects UDP floods (Bedrock edition uses UDP/19132), SYN floods targeting the Java TCP port, and amplification attacks. The PCAP capture gives you packet-level evidence of exactly what the attacker sent, which is useful for building upstream filter rules or submitting abuse reports.
How does Flowtriq handle UDP floods?
The Flowtriq agent monitors UDP traffic at per-second resolution, tracking packets per second, bytes per second, source IP distribution, and destination port patterns. When UDP traffic deviates significantly from the server's learned baseline, the agent classifies the attack type based on traffic characteristics: pure random-source UDP floods are classified differently from DNS amplification (recognizable by the source port 53 and amplification factor), NTP amplification (source port 123), SSDP amplification (source port 1900), and other reflection vectors. The classification fires within approximately 1 second of attack onset. A webhook fires to your automation infrastructure with the classification details, which you can use to apply targeted upstream ACLs or trigger scrubbing for the specific attack vector.
Can Flowtriq work alongside a BGP scrubbing provider?
Yes, and this is a common deployment pattern for game hosting operators. Flowtriq provides the detection and classification signal; your BGP scrubbing provider provides the mitigation capacity. When Flowtriq detects an attack on a server, the webhook payload includes the attack type, target IP, and severity. Your automation toolchain uses this to trigger selective diversion through your scrubbing provider (via BGP announcement of the attacked prefix) rather than blanket diverting all traffic. This means your scrubbing provider only handles IPs that are actually under attack, and the mitigation is triggered by a precise, classified detection signal rather than a volume threshold. The result is faster activation and fewer false-positive diversions.
What is the detection latency for a SYN flood?
Approximately 1 second. The Flowtriq agent evaluates per-second traffic snapshots. For a SYN flood, the agent tracks the ratio of SYN packets to SYN-ACK and established connection completions. A SYN flood produces a characteristic pattern (high SYN rate, near-zero established connections) that deviates immediately from the server's learned baseline. The first anomalous second triggers classification and alert dispatch. In practice, the end-to-end time from first attack packet to webhook notification is typically 1-3 seconds, depending on webhook delivery latency to your automation endpoint. This is fast enough that a mitigation rule applied in response to the webhook will be in place within 5-10 seconds of attack onset, before most players experience perceptible latency degradation.
