Why AetherisAC?
Advanced Detection Technology
AetherisAC employs world-class detection systems used by premium anticheats:
AetherisAC employs world-class detection systems used by premium anticheats:
- Movement Prediction Engine – Validates all movements against physics-based predictions, ensuring only legitimate actions are allowed
- Transaction System – Eliminates lag-based false positives by tracking packet order and timing
- Behavioral Analysis – Learns each player's unique patterns and detects statistical anomalies with 99.7% confidence
- Multi-Layered Validation – Each check contains 5-7 independent sub-checks that must ALL be bypassed
Professional-Grade Mathematics
- GCD Analysis – Mathematical proof of aim assistance through rotation pattern detection
- Z-Score Anomaly Detection – Statistical validation with confidence intervals
- Ray Tracing – Precise hit detection simulation using vector mathematics
- Physics Simulation – Real gravity (0.08), drag (0.98), and friction (0.91) calculations
Support
Our support team responds to tickets within minutes — often instantly — whenever a staff member is available. With team members across multiple time zones, you'll always find someone ready to help.
Unlike other services, Aetheris offers real human support with no bots or hidden fees required to get assistance.
Customization
AetherisAntiCheat provides one of the most extensive configuration systems and APIs available. Every aspect of detection, punishment, and messaging can be customized to suit your server's needs.
You're in full control — from sensitivity to violation limits — all through a simple and easy-to-edit configuration file.
⚡ Simplicity
No extra setup or paid add-ons required. Simply drag and drop AetherisAntiCheat (and PacketEvents) into your plugins folder, restart your server, and you're protected instantly.
It just works — right out of the box.
