False Positives in Anti-Cheat: A Guide for Small Studios

For indie studios, the safest approach is to treat anti-cheat as a signal system first and an enforcement system second.

Detection is not always enforcement

A detection means something unusual happened. It does not always mean the correct response is a permanent ban.

Some events are strong signals. Others are weak indicators that only matter when combined with more context. A suspicious handle, a strange module, unusual aim timing, or unexpected value change may each mean different things depending on the game and environment.

The more serious the punishment, the stronger the evidence should be.

Context matters

Legitimate software can interact with games in unusual ways. Overlays, capture tools, accessibility tools, graphics utilities, platform clients, and security software may all affect the runtime environment.

A good anti-cheat layer should not treat every unfamiliar event the same way. It should consider signature status, behavior, timing, memory characteristics, and whether multiple signals point in the same direction.

Use severity levels

Instead of thinking in terms of cheat or not cheat, use severity:

• informational events for visibility
• low severity for weak signals
• medium severity for suspicious context
• high severity for strong tampering evidence
• critical severity for immediate enforcement cases

This gives the studio more control. It also makes early tuning much safer.

Prefer reversible responses first

For uncertain cases, a kick, session invalidation, match exclusion, or temporary review flag may be better than a permanent ban.

Permanent bans should be based on strong, repeatable, or corroborated evidence. This is especially important during early access, when the game may still have bugs and unusual edge cases.

Review your own assumptions

Anti-cheat should improve over time. If a detection creates support tickets, review it. If legitimate tools are being flagged, tune it. If cheaters are adapting, update the signals.
