Anti-cheat
Server-side anti-cheat for serious CS2 matches.
Learn how Ouro's server-side anti-cheat collects tick-by-tick gameplay data throughout live matches and flags suspicious behavior patterns.
// 01 -- COLLECTION
What Ouro collects
The anti-cheat watches the match from the server side and builds decisions from a wide set of gameplay signals. That includes timing, visibility, angles, shots, kills, and the sequence connecting them.
Collected on every tick
Ouro captures live gameplay context on every tick so suspicious behavior is analyzed as it unfolds, not only after a match ends.
Server-owned evidence
The important anti-cheat signals come from the match server, not from clips, claims, or client-side data a cheater can shape around.
Server-side events
The system watches real server events rather than relying on clips, accusations, or what a player claims happened.
Angles, timing, and visibility
Signals like angles, visibility, shots, kills, movement, and timing are evaluated together so single moments are never the whole story.
Pattern-based evidence
Ouro looks for repeated patterns over time, building decisions from broad context instead of reacting to one strange highlight.
// 02 -- DETECTION
What it can detect
Ouro can detect representative cheating patterns such as prefire angles that appear too consistent, hits through walls or before valid visibility, rapid trigger behavior, rapid kill sequences, and reaction-time or time-to-kill patterns that look too strong to be human. These examples are not the full list.
Suspicious behavior categories
- Prefire angles that repeat too cleanly and too often.
- Damage or hits that happen through walls or before proper visibility.
- Trigger behavior that is unnaturally fast or mechanically consistent.
- Kill chains and time-to-kill reactions that do not look natural.
- Repeated outlier patterns that stand apart from normal established play.
Why we do not publish every pattern
Players should understand that Ouro tracks a vast amount of data to support fair-play decisions. At the same time, we do not publish the full pattern library or decision logic because doing that would make it easier for cheaters to study around the system.
// 03 -- CONTEXT
Why server-side matters
Clips and reports only show fragments. Server-side analysis sees the whole engagement timeline tick by tick, which means Ouro can judge suspicious behavior with more context than a single moment ever can.
How the system evolves
Ouro is constantly adding and testing new patterns as more gameplay data flows through the system. Long-established, legitimate players help strengthen the comparison baseline over time, which means the anti-cheat gets better at separating high-level legitimate play from suspicious outlier behavior.
// 04 -- SERVER-SIDE FIRST
Server-side by design.
Most competitive platforms lean on a client-side anti-cheat that installs on the player's computer and tries to detect cheat software before it runs. Ouro inverts the priority on purpose: server-side analysis is the foundation, and a complementary client-side layer is being added to catch what server-side structurally cannot see.
The arms race problem
Client-side anti-cheats, including kernel-level drivers that run with the deepest access on your operating system, create a constant arms race. Cheat developers reverse-engineer the detection, publish an update, and the cycle repeats. Even the largest platforms with dedicated security teams see their client-side protections bypassed regularly.
At the extreme end, hardware-based cheats known as DMA (Direct Memory Access) devices bypass client-side detection entirely. A DMA device is a separate piece of hardware, often plugged into a PCIe slot or connected via Thunderbolt, that reads the game's memory from outside the operating system. Because the reads happen below the OS layer, no software running on the player's machine, not even a kernel driver, can reliably see them. These setups are expensive, but for a motivated cheater they make client-side anti-cheat irrelevant.
Why Ouro chose server-side
Server-side analysis cannot be tampered with from the player's machine. It does not matter what software or hardware a cheater uses locally because the server collects its own data independently. Combined with identity verification that makes bans meaningful instead of temporary, and a reputation system that tracks behavior over time, the result is a layered defense where each part compensates for the others.
A complementary client-side layer is in active development and is on the near-term roadmap. It is scoped to cover specific checks server-side analysis structurally cannot see — not to replace the foundation. Server-side detection and identity-backed consequences stay primary, because that is where the structural advantage lives.
// 05 -- HOW ACTION WORKS
How action works
The public version is simple on purpose: live server data is collected, suspicious patterns are flagged, full context is reviewed, and action follows when the evidence is strong enough.
Live events are collected
Gameplay data arrives continuously from the server throughout the match.
Suspicious patterns are flagged
The system compares those events against representative cheating patterns and broader private checks that are not publicly listed.
Context is reviewed
Behavior is evaluated with the full sequence of what happened before, during, and after the engagement.
Action follows evidence
Decisions are made when the evidence is strong enough, with confidence built from accumulated server-side context.
// 06 -- FAQ
FAQ
Enough detail to build confidence, without disclosing the full system.
Does the anti-cheat run during live matches?
Yes. Ouro collects server-side gameplay data live during the match on every tick.
Is this only based on reports or clips?
No. Reports can help direct attention, but the anti-cheat itself is built around server-side event collection and pattern analysis.
Do you publish every detection pattern you use?
No. We name representative categories so players understand the system, but the full pattern library and decision logic stay private because publishing them would help cheaters adapt.
Does the system stay static over time?
No. Ouro continuously adds and tests new patterns as more gameplay data flows through the system and the baseline for legitimate play gets stronger.
Is Ouro adding a client-side anti-cheat?
Yes — a complementary client-side layer is in active development and is on the near-term roadmap. It is designed to cover specific things server-side analysis structurally cannot see, while server-side detection and identity-backed consequences remain the foundation. We are not betting the platform on a kernel driver; we are layering it on top of detection that already cannot be tampered with from the player's machine.
What is a DMA cheat and why does it matter?
DMA stands for Direct Memory Access. It is a separate hardware device that reads game memory from outside the operating system, making it invisible to any software running on the player's computer, including kernel-level anti-cheat drivers. This is one of the reasons Ouro focuses on server-side detection, where the data is collected independently and cannot be interfered with from the client.
