Stateful Inspection
Unlike basic firewalls, Cosmicguard performs deep packet inspection (DPI) to understand the “state” of a connection.
- Legitimacy Checks: Validates that incoming packets actually belong to the game protocol (e.g., verifying a valid Minecraft handshake).
- Anti-Flood: Automatically drops malformed packets before they reach your CPU.
A2S Query Caching
For Valve games (CS2, TF2, Rust, GMod), server info queries can be a major source of lag.
- Hardware Caching: Cosmicguard caches your server’s metadata (player count, map, name) at the network edge.
- Server Offloading: Queries are answered by the firewall, not your server, saving significant CPU resources and preventing “Server Not Responding” errors.
Network Infrastructure
Cosmicguard is built on a high-speed fiber backbone designed for zero jitter.
- Global Scrubbing: Distributed nodes handle traffic locally.
- Ultra-Low Latency: Optimized routing ensures that protection does not add significant delay to your players’ connection.
Unified Ruleset
Managing Cosmicguard is simple because it uses a single, unified ruleset for all protocols:
- TCP/UDP/ICMP: All can be configured from a single interface.
- Stateful Presets: One-click presets for complex games like FiveM or Palworld.
