Cyrex Ltd.

Cyrex Ltd. is a security and performance testing consultancy that works mainly with game studios and enterprise technology firms. It probes multiplayer games and business platforms for exploitable flaws and checks whether their infrastructure holds up under heavy user load before launch.

What Cyrex Ltd. offers

• Penetration testing — offensive security work on applications, finding broken logic, data leaks, economy manipulation and other exploits.
• Pair Hacking — the firm's name for its method of combining senior security engineers with its own AI tooling.
• Load testing — simulating large numbers of concurrent users to find where servers, queues, matchmaking and databases fail.
• Network and infrastructure review — work on latency, packet loss and poorly optimised cloud setups.
• Complex environments — testing of custom multiplayer protocols, IoT and OT systems, and internal logic flows.
• Software development — building applications, which the older company description lists alongside its security work.

Who it works with

Game studios, including AAA developers, and large enterprises running SaaS platforms. The firm says it has worked with more than 150 studios and technology companies.
