Always-on DDoS protection for game servers.
Comprehensive L4 and L7 mitigation, granular per-IP firewall rules, and edge packet caching — running on every machine we host, at no extra cost.

Edge Locations
Per-IP
Granular Configuration
Firewall Manager
Full control over your network security with an advanced firewall manager built for game server operators
Granular Rule Manager
Create precise firewall rules per IP with source, destination port, protocol, and action controls. Copy rules between IPs or apply default drop profiles in one click.
Attack History & Analytics
Full visibility into past and ongoing attacks with detailed logs, traffic graphs, and mitigation stats so you always know what hit you and how it was handled.
Edge Packet Caching
Offload repetitive query traffic like A2S with edge caching. Responses are served at the network edge, reducing load on your server and keeping latency low.
Per-IP Configuration
Every IP on your dedicated server gets its own independent firewall profile. Tailor rules and protections per service without affecting your other workloads.
The Best DDoS Protection
Always ActiveAll services come with comprehensive L4 and L7 DDoS protection powered by Cosmic Global Networks, ensuring your infrastructure stays secure and available 24/7.
See What's Hitting You
Every mitigation event is logged and surfaced in your dashboard so you always know what was absorbed before it touched your server
Most "DDoS protected" hosts hide everything behind a green checkmark. We don't. Your firewall dashboard shows every attack our edge mitigates on your IPs — when it started, when it ended, how long it lasted, and which target was hit.
No ticket needed, no waiting on a status page. The mitigation happens automatically at the network edge and the audit trail is yours to inspect at any time.
- Per-IP attack history scoped to the machines you own
- Filter by machine to drill into a specific service
- Live status while a mitigation is in progress
Edge Packet Caching
Offload repetitive query traffic to the network edge so your server only handles what matters
Game server browsers hammer your machine with status queries — A2S for Steam titles, RCON-style probes for others. Each one is small, but at scale they eat CPU and become a vector for amplification attacks.
Turn on edge caching and those queries are answered at the network edge instead of touching your machine. Your server stays focused on real player traffic, your latency stays low, and amplification reflectors go nowhere.
- Per-IP, per-port configuration — enable only where you need it
- Built-in profiles for Steam A2S and other common query protocols
- Included on every plan at no extra cost
How Mitigation Works
Three layers between an attack and your server, all running automatically
Detect at the edge
Traffic destined for your IPs is inspected the moment it enters our network. Anomalous patterns are identified before they reach your machine.
Scrub automatically
Malicious traffic is dropped at the edge by L4 and L7 mitigation profiles. Legitimate players continue to connect without interruption.
Log for transparency
Every mitigation event is recorded and surfaced in your dashboard so you can review what happened and when.
Mitigation at every edge
Attacks are absorbed close to where they originate. Clean traffic continues to your server with minimal added latency. View all locations.
Frequently Asked Questions
Everything you need to know about DDoS protection at GameServerKings
Yes. L4 and L7 mitigation is on by default for every game server and dedicated server we host, at no extra charge. There is nothing to enable, no add-on to buy, and no traffic threshold below which protection is disabled.
L4 (transport layer) covers volumetric and protocol attacks — UDP floods, SYN floods, amplification reflections, and similar. L7 (application layer) handles attacks that look like real traffic, such as HTTP floods or game-protocol abuse. We mitigate both at the network edge, so neither type ever reaches your server.
No. Mitigation kicks in automatically the moment our edge detects an attack pattern. There is no panic button, no escalation ticket, and no on-call rotation you need to maintain. The attack is logged in your firewall dashboard so you can review it after the fact.
Game server browsers send constant status queries to your IP — A2S for Steam, custom probes for other engines. Edge caching answers these queries at the network edge instead of forwarding them to your machine, which reduces CPU load and removes a common amplification-attack vector. You configure it per-IP and per-port from the firewall manager.
Yes. Every mitigation event is logged in your client area with the target IP, machine, start time, end time, and duration. You can filter the log by machine to focus on a specific service.
Our parent network, Cosmic Global Networks, offers remote DDoS protection for infrastructure hosted elsewhere. Traffic is routed through our scrubbing locations and clean traffic is delivered back to your origin. Contact our team for a quote.
Mitigation applies to all standard game and web traffic on your server. If you are running an unusual protocol or need custom rule profiles, you can build them in the firewall manager or contact support to scope a custom configuration.
