What is a DDoS attack?

A distributed denial of service (DDoS) attack floods a server or network with traffic from many sources at once, exhausting bandwidth or system resources so legitimate users can't reach the service.

How does Cosmic Guard mitigate DDoS attacks?

Traffic is routed through globally distributed scrubbing PoPs that inspect every packet, drop attack traffic in sub-second time, and forward only clean traffic to your origin. Mitigation is unmetered and always-on.

Purpose-built for Rust, FiveM, Minecraft, Ark

The kick storm hits, players never notice.

Game server operators on Cosmic Guard

Every game engine, mitigated the way it wants to be

Rust & Rust servers

Wipe-day connection floods

The three hours after a wipe are the busiest — and the loudest. We fingerprint the Rust query protocol (A2S) and drop spoofed handshakes upstream of your box, keeping the queue moving for real players.

FiveM & RedM

Slot-flood and endpoint spam

FiveM's txAdmin API is a common target. Our per-slot fingerprinting separates real join attempts from scripted slot-holds, and rate-limits the txAdmin surface without touching your ACL.

Minecraft, Java & Bedrock

Bot pings and legacy ping floods

Bedrock's RakNet and Java's MOTD ping are both trivial to spoof. Our filters know both protocols, so we absorb the flood at the edge and your ping list stays clean.

Ark, Terraria, custom UDP

Anything with a public UDP port

Ark's RCON port, Terraria's TShock, or your own custom UDP daemon — we scrub every packet against known and adaptive signatures, without touching your game protocol.

The Cybersecurity Threat of DDoS

What is a DDoS?

A distributed denial-of-service attack (DDoS attack) is when an attacker floods a victim's internet network with malicious traffic, aimed at overwhelming it and causing catastrophic downtime ranging from seconds to weeks.

This downtime can cause permanent damage to your brand, loss of customer confidence, and major financial loss.

Any internet-facing property your organization and users rely on is potentially vulnerable to DDoS attacks.

DDoS Protection

DDoS Mitigation solutions are designed to combat these attacks by separating the good traffic from the bad traffic.

However, not all DDoS solutions are built the same.
Some have issues that can do more harm than help:

Slow mitigation times causing downtime for minutes
High-latency unsuitable for high-speed applications
False positives blocking real customers
Failure to protect against sophisticated attacks
