You spend months getting a framework, scripts, and a launch plan right. Then real players show up, and so does the first executor menu. One broken economy and a Discord full of refund requests later, you learn the same lesson every established server already knows: growth and security are the same job, not two separate ones.

Short answer:Cfx.re does not ship a built-in anticheat and explicitly allows server owners to run third-party anticheat resources. Choosing one comes down to evaluating detection approach, performance cost, how fast it updates against new cheats, and the reputation of the team behind it, then layering it on top of FiveM's own server-hardening tools rather than treating any single resource as a complete solution. FiveM Coach recommends and has partnered with ZeroTrust.

Why FiveM needs a dedicated anticheat at all

Cfx.re's own resource FAQ answers this directly: "FiveM allows you to run any resource within the terms, and you are free to use anticheat resources." The platform intentionally leaves detection to server owners rather than baking one system in for everyone. Its guidance on what to do against cheaters is specific: report usable hacks to [email protected], use OneSync's server-authoritative features to build secure code, and, in Cfx.re's own words, build or maintain a server-side anticheat "together with the community."

That server-authoritative model matters because of where the real risk sits. Cfx.re's server security documentation is blunt about the trust boundary: a compromised client can trigger networked events in almost any context it wants. A script that registers a networked event and trusts whatever the client sends, money amounts, item counts, positions, is the exact gap a cheat client walks through. OneSync gives you the infrastructure to keep that state on the server instead of the client. It does not, by itself, watch for the injector or mod menu trying to abuse it. That is the job an anticheat resource does.

Signs a cheating problem is already active

Cheating rarely announces itself with an obvious mod menu on stream. It shows up first as a pattern your team half-notices and explains away. Money or high-value items appearing in a player's inventory with no matching transaction in your logs is the clearest signal, since it usually means an event meant to be validated server-side accepted a value straight from the client instead. Reports of a player teleporting, moving at impossible speed, or surviving damage that should have killed them are the second pattern, and they tend to cluster around whichever job or vehicle script has the weakest event checks. A sudden wave of reports after a popular script update ships is the third: cheat developers actively target new resources before server owners have finished testing them.

None of these confirm a specific cheat on their own, but two or more showing up in the same week is enough reason to stop treating anticheat as a someday project.

What to evaluate before you buy one

Detection approach

Server-side behavioural detection, watching what a client actually does through the network layer, tends to hold up better over time than approaches that depend entirely on a shared list of known bad players. Cfx.re's own policy explicitly disallows resources built around global ban lists, stating plainly that "we have no way to verify the quality of every anticheat, and it may very well be possible for a global ban list to ban players without good reason." An anticheat that leans on active detection rather than an unverifiable shared blacklist is the safer bet for your players.

Performance cost

Every resource you run competes for the same tick budget. Before you commit to an anticheat, check what it actually costs in Resmon under real load, not just at idle. If you are not sure how to read that number yet, our guide to diagnosing high Resmon usage covers what a healthy Time% looks like and what does not.

Update cadence and bypass resistance

Cheat menus change constantly, and an anticheat that shipped a great release two years ago and has gone quiet since is not protecting you today. Ask a vendor directly how often detections are updated and whether that has kept pace with current mod menus, not just how the product looked at launch.

Reputation and transparency

This is the criterion most owners skip, and Cfx.re's own policy exists because of it. The same resource FAQ explicitly bans "protection rackets, in other words, (former) authors of hacks extorting server owners to buy their anticheat," calling it a Terms of Service violation. Before you pay for anything, find out who actually built it, how long they have operated in the open, and whether real communities will vouch for them.

Multi-server management

If you run, or plan to run, more than one server, a dashboard that manages detection and bans across every instance from one place saves real operational time over configuring each server separately.

The categories of anticheat operators actually run

In practice, server owners land on one of three approaches.

  • Do-it-yourself, server-side checks.Following Cfx.re's own event-security guidance, validating money, items, and position server-side, checking event source, rate-limiting suspicious calls, costs nothing but developer time, and it is only as good as the person maintaining it as new exploits appear.
  • Community-released resources. The Cfx.re forum hosts a wide range of free and paid anticheat releases. Quality and support vary enormously between them, and none are independently audited by Cfx.re itself, so the vetting work in the previous section applies directly here.
  • Dedicated commercial anticheat services.A paid product with a dashboard, active maintenance, and a support channel is where most servers with real player counts and progression to protect end up, because the detection work is someone else's full-time job instead of a side project.

A simple framework for choosing

Weigh four questions honestly before you commit budget:

  1. How many players and how much economy do you actually have to protect right now, and how much will that grow in the next six months?
  2. Do you have in-house development capacity to build and keep patching your own detection, or is that time better spent on content and community?
  3. Are you running one server or planning a network, since that changes whether dashboard-based multi-server management is worth paying for?
  4. Can you verify the team behind the product has a real track record, given Cfx.re's own warning about protection-racket schemes in this exact space?

A brand-new public server with a handful of players can often start with solid server-side event security and FiveM's own hardening convars. A server with a real economy, whitelisted applications, and a community that will notice a cheating wave within the hour is exactly the profile where a dedicated commercial anticheat earns its cost back the first time it catches something your own checks would have missed.

The cleanest framework and the best scripts do not matter if one cheat wave undoes months of work in a single night. Protect the player experience first, then scale it.

Our pick: ZeroTrust

FiveM Coach has partnered with ZeroTrust, the anticheat we point owners to when security keeps coming up in build-and-grow conversations, which is almost every one of them. ZeroTrust runs dashboard-driven detection and management across multiple servers from a single setup, and it is already used by established roleplay communities including Georgia State RP, Nightfall RP, Vision V2, Riptide RP, and Horizons RP. You can read more about the partnership and what it covers in our FiveM Coach and ZeroTrust partnership announcement.

No anticheat, ZeroTrust included, is a substitute for building your scripts securely in the first place. It is the layer that catches what gets past everything else, not a reason to skip server-side validation.

Layered defense beyond any single anticheat

Whatever you choose, pair it with the hardening Cfx.re already ships.sv_pure_verify_client_settings verifies client settings like pure level and scripthook status against the server. sv_filterRequestControl blocks suspicious entity-control requests, with modes ranging from filtering only settled player-controlled entities up to blocking REQUEST_CONTROL_EVENT routing entirely. sv_kick_players_cnl_timeout_sec kicks clients whose connection integrity checks stop responding. None of these replace an anticheat, but running with them disabled while relying entirely on a third-party product is leaving free protection on the table.

On the code side, the fix is unglamorous but effective: register cross-context events with validation instead of blind trust, verify money, item counts, and position server-side rather than accepting whatever the client reports, and rate-limit anything a player could spam. If you are not sure your own scripts already do this, an audit before launch catches it before players do.

The bottom line

FiveM leaves anticheat entirely up to you, and that is by design. Evaluate any product on detection approach, real performance cost, how fast it keeps up with new cheats, and whether the team behind it has an actual track record, not a launch-week claim. Layer it on top of FiveM's own hardening convars and secure server-side code instead of treating it as the only line of defense. If you want the anticheat side handled by a team we already trust, start with ZeroTrust, and if you are still building or growing the rest of the server around it, that is what FiveM Coach membership is for.
