ECLIENTProtected Environment
A lightweight executable client that verifies your Steam identity, monitors session integrity, and keeps servers clean.
Steam Only
Authentication
Easy to Use
Execute and Play!
24/7 Session
Continuous Monitoring
Built for integrity
Steam identity verification
OAuth-based Steam login binds your account to a machine-unique hardware fingerprint. No credentials ever stored locally.
Encrypted session comms
All telemetry and heartbeat data is encrypted with AES-256-GCM over a secure WebSocket channel with nonce-based replay protection.
Real-time session monitoring
Memory polling at ~60 Hz captures gameplay events. Periodic heartbeats and server-requested scans keep the session continuously validated.
HWID fingerprinting
A hardware-derived fingerprint correlates sessions across reconnections bound to the originating machine.
Live Screenshots from players
Take screenshot of the suspicious player's screen without asking for the image manually. Everything automatic for further investigations.
Files Integrity check
Ensures the authenticity and completeness of all client files through cryptographic hashing and signature verification.
