Why ItzyGuard?

ItzyGuard isn't just a client-side cheat scanner.

The Guard Client, Guard Server, Process Scanner and Network Defense systems work together to provide both client security and server-side enforcement.

Administrators remain in control of sensitive decisions, while automated systems handle monitoring, logging, strikes, blocking and repeat offenders.

The system is configurable depending on how strict you want your server protection to be.

Important

Local Fast Flood Mitigation is designed to protect the server locally against abusive TCP connections and connection floods.

It is not advertised as upstream DDoS protection and cannot prevent a volumetric attack that has already saturated the host's internet connection.
