Anti-cheat in 2026 is a layered contest, not a race that AI is winning or losing. Riot Games and Electronic Arts both say AI is making cheats easier to build, and both use machine-learning and behavioral models to flag suspicious play. The larger shift is in where they draw the line on software. Riot has set October 6, 2026 as the start of a default block on unapproved third-party tools reading or writing game memory, while EA relies on kernel-level components, anti-DMA protection, and input-device checks. Each layer catches something the others miss, and each asks more of the player’s PC or raises questions about false positives and accessibility hardware.
What changed in 2026
Riot removes default game-memory access for unknown third-party apps
Riot Games says that starting October 6, 2026, it will proactively block game-memory access by default for all unknown third-party applications across League of Legends, Teamfight Tactics (TFT), and VALORANT. Its support notice, “Game Memory Access Removed for Third Party Apps,” puts it this way: “Starting October 6, 2026, Riot will begin proactively preventing game memory access by default for all unknown third-party applications, for all titles, including League, TFT, and VALORANT.”

Until now, Riot has allowed memory access for trackers, overlays, and mods. Tools that are already approved get a grace period through April 2027, after which they must use official APIs. Riot’s stated reason is that AI-assisted reverse engineering has expanded the number of would-be cheat makers and is being used to build cheats, bot farms, and attacks on in-game experiences. Riot also expects the change to reduce cheating and crashes. That is the company’s expectation, not an independently measured result.

Riot’s “Vanguard On-Demand” article, written by Phillip Koskinas, whom Riot identifies as managing its competitive integrity portfolio, argues that as AI lowers the barrier to botting, the security bar for entering competitive play has to rise. Riot says it prefers incentives to universal requirements. It reserves heavier checks for highly competitive segments, unusual devices, or high ranks. Koskinas writes: “Ultimately, for competitive online spaces to persevere, it is necessary that we be able to trust the endpoints that the games are played on.”
#1 Best Overall
EA’s Javelin year in review
EA’s September 10, 2026 update on Javelin Anticheat describes a year of detection work: anti-DMA protection, defenses against malicious input devices, countermeasures for macro software and synthetic input, seven major upgrades, and hundreds of smaller improvements. EA says it continues to invest in machine-learning models, behavioral analysis, and hardware-level defenses.
Why AI cuts both ways
The same tools help both sides. Riot says AI-assisted reverse engineering has made it easier for people to build cheats, bots, and attacks against games. On the defensive side, Riot and EA use machine-learning and behavioral models to find suspicious play. EA says it has built a new Apex Legends model for a newer generation of bots, designed to handle future variants. Neither company publishes a success rate that covers the whole contest, so the balance cannot be read from either side’s claims alone.
How machine learning detects cheats, and where it stops
Riot says it uses machine models to predict the likelihood that a player is cheating. Its main limit is the data. Server-side information does not give enough detail to catch informational cheats, which do not change a player’s input. Riot names ESP, fog-of-war leaks, and radar hacks, and says that from server data alone these are “almost totally undetectable.” Riot’s point is that a model can see what the player does, but not what the player already knows.

Riot’s server-side ceiling for aimbots
For aimbots, Riot’s estimate from its “/dev: Vanguard x LoL” article is that the best server-side-only models identify around 30–50% of them. Riot says that recall is not enough for its free competitive games. This is Riot’s own estimate for League of Legends, not a field-wide measurement.
EA’s Apex Legends model for newer bots
EA says it created a new Apex Legends machine-learning model for a newer generation of bots, designed to handle future variants. An earlier EA Apex update described initial reviews as accurate with low false negatives, but it gave no percentage. This is EA describing its own system. It is not a measured comparison with Riot’s approach.
An academic benchmark: AntiCheatPT_256
AntiCheatPT_256 is an academic preprint, not a shipped anti-cheat product. It uses a transformer model evaluated on Counter-Strike 2 gameplay data, with a dataset of 795 labeled matches and 90,707 context windows. On an unaugmented test set, the paper reports “89.17% accuracy and 93.36% AUC — AntiCheatPT_256 paper authors, 2025.” The result applies to the paper’s dataset and should not be set beside Riot’s or EA’s operational figures.
The layers beyond machine learning
Model scoring is only one layer. The others change what the anti-cheat can see on the player’s machine, and that is where most of the player-side trade-offs sit.
Kernel-mode drivers and boot-time loading
Riot’s 2020 explanation of Vanguard describes three parts: a user-mode client, a kernel-mode driver, and a platform. The client handles detections while a game is running. The driver validates memory and system state and starts with the computer, so that cheats are blocked before they can load ahead of the client. Riot says kernel-level access is needed to respond to cheats running at higher privilege, including DMA methods that relay memory to another machine. The same page says Riot coordinated the design with its Security and Data Privacy teams and that the driver does not send computer information back to Riot. These are Riot’s statements about the design as described in 2020, not a current audit.
Kernel scope in EA’s Javelin
EA’s September 2026 update says Javelin runs at kernel level only while a protected game is running and shuts down when the game closes. That limits how long the kernel component is active, although it does not change what the component can access while the game runs.
Hardware, firmware, and boot settings in VALORANT
Riot’s motherboard security update says restrictions can stop VALORANT from launching if system security features are disabled or if the system’s behavior resembles suspicious hardware configurations. Riot cautions that a restriction does not necessarily mean it suspects the player of cheating. In some cases it points players to enable the relevant features or to update motherboard firmware, following the manufacturer’s official guidance.
Input-device enforcement in Apex Legends
EA lists XIM, Cronus, Strike Pack, and similar hardware as cheating when used to automate actions, modify recoil, alter input behavior, or simulate unintended controls for an advantage. These devices are examples of prohibited tools, not recommendations. EA says its multi-layer detection for Apex is planned, and that confirmed cheating will receive permanent bans.

The player-side cost: intrusiveness, false positives, and accessibility
Each control gives up something on the player’s side. The table compares what each one asks of the player and what error handling the publisher describes.
| Control | Scope | Player-side requirement | Error handling stated by the publisher |
|---|---|---|---|
| Riot third-party memory rule (League, TFT, VALORANT) | Unknown third-party apps reading or writing game memory | Not stated for players; approved tools must move to official APIs by April 2027 | Not stated |
| Riot Vanguard (2020 description) | Kernel-mode driver that starts with the computer | Kernel-mode driver running from boot | Not stated |
| EA Javelin (2026 update) | Kernel level only while a protected game is running | Kernel-level access during play; EA reports that over 4.8 million players enabled Secure Boot after it introduced configurable requirements | Self-reported false-positive rate below 1%; an appeals process exists; review specifics withheld |
| Riot VALORANT hardware and firmware checks | System security features and hardware configurations | System security features enabled; firmware updated where Riot advises it | Riot says a restriction does not necessarily mean suspicion of cheating; appeals not described in the guidance |
| EA Apex input-device detection (planned) | Hardware used to automate actions or alter input | Not stated | Designed to separate cheating devices from legitimate accessibility tools; no false-positive figure given for this check |
False positives and appeals
EA says it balances detection speed with accuracy: “We balance detection speed with accuracy.” It reports a false-positive rate below 1% for Javelin. That figure is self-reported, and EA does not say it applies to every check on every game. EA says it maintains an appeals process but withholds review specifics to reduce exploitation. Riot’s motherboard guidance does not describe an appeal, so a player blocked by that restriction should contact Riot support.
Accessibility devices
Input-device enforcement raises a specific concern: can accessibility hardware be mistaken for a cheat? EA says Apex’s planned multi-layer detection is designed to distinguish cheating devices from legitimate accessibility tools. The company’s statement describes the design, not the results. No false-positive figure is given for that check, so players who depend on adaptive hardware should keep records of their setup and use the appeals route if they are flagged.
Reading the published numbers
The figures below come from different publishers, games, and periods, and most are the publisher’s own reporting. They do not add up to one detection rate.
| Figure | Source and date | Scope | What it measures |
|---|---|---|---|
| 277,649 attempts prevented | Electronic Arts, 2026 (through July) | Battlefield 6 and Javelin AntiCheat | Attempts to cheat or tamper that were stopped before they affected matches |
| About 1,200 accounts actioned; about 17.4 million ranked points removed | Electronic Arts, Apex Legends update (year not stated in the source) | Apex Legends | Accounts actioned and ranked points removed |
| Around 30–50% of aimbots identified | Riot Games, “/dev: Vanguard x LoL” (date not stated) | League of Legends; best server-side-only models | Share of aimbots identified by Riot’s own models |
| Below 1% false-positive rate | Electronic Arts, Javelin update, September 10, 2026 | Javelin AntiCheat | False-positive rate, self-reported |
| 89.17% accuracy; 93.36% AUC | AntiCheatPT_256 paper authors, 2025 | Counter-Strike 2; unaugmented test set of 795 labeled matches | Classifier accuracy and AUC on the paper’s test set |
| 45,000 players’ launch issues resolved within 48 hours | Electronic Arts, 2025 (October 2025 AMD Anti-Lag compatibility fix) | Launch compatibility, not cheating | Players whose launch issues the fix resolved |
| Over 4.8 million players enabled Secure Boot | Electronic Arts, 2026 update | Not stated | Players who enabled Secure Boot after configurable requirements were introduced |
If a restriction blocks you
- Read the message the client shows and note which game and which restriction it names before changing anything.
- For a VALORANT launch block tied to system security, confirm that the relevant security features are enabled in your motherboard firmware, and update firmware only through the manufacturer’s official guidance. Riot says a block does not necessarily mean it suspects cheating.
- If you use a tracker, overlay, or mod with League, TFT, or VALORANT, ask its developer whether it is moving to official APIs. Tools that are already approved must do so by April 2027.
- If you believe an enforcement action against your account is wrong, use the publisher’s appeals process where one is described. EA says it maintains one. For Riot restrictions, contact Riot support.
- Do not use hardware that EA names as cheating tools in Apex Legends. Confirmed cheating can lead to permanent bans.
What this picture leaves out
This article covers Riot Games and Electronic Arts. It does not describe the systems of other publishers, including Valve, and should not be read as representative of the industry. The company figures are not independently verified, and no industry-wide detection rate exists in the sources. Policy dates and game requirements can change during 2026 rollouts, so check each publisher’s current support page before relying on a specific date.
