Protection & Anti-Cheat

Guard systems, anti-bot and exploit fixes for your pack.

Server protection built into the architecture: packet validation, rate limiting, anti-bot heuristics and exploit fixes.

Most exploited servers were not targeted by geniuses - they left the front door open. Protection isn't a single product you bolt on; it's a mindset that runs through packet validation, economy design, rate limiting and admin tooling. We build guard systems and anti-bot heuristics tailored to your pack, fix dupe and exploit classes, harden the admin surface, and audit existing servers.

What's included

  • Server-side validation of movement, items, trades, enchant and skills
  • Rate limiting and impossible-sequence detection on high-risk packets
  • Anti-bot heuristics and behavior analysis
  • Economy hardening against duplication
  • Admin surface hardening and full command auditing
  • Exploit and dupe fixes with regression tests
  • Optional: integration with third-party anti-cheat

Example work

  • Guard layer stopping packet-injection movement hacks
  • Adena-flow anomaly detection with staff alerts
  • Full pre-launch security audit of a custom pack
