FiveM Anti Cheat Setup: A Step-by-Step Guide for Owners

Do FiveM anti cheat setup in this order: audit your own resources and server events, harden the server, install and configure the anti cheat, tune detection sensitivity over a week rather than on day one, route alerts to Discord and your dashboard, and write your ban policy before the first detection lands. The install itself takes minutes. Everything around it decides whether the anti cheat is actually useful.

Most setup guides start at the install. That is the wrong end. Here is the order we use, starting with the step we see skipped most.

Step 1: Audit your own resources before you install anything

Say it plainly: no anti cheat replaces proper server-side event validation. If a resource registers a server event that hands out money, items, jobs, or vehicles, and the handler does not verify on the server that the calling player is allowed to make that request, you have an exploit surface no anti cheat can fully close.

A player can trigger that event from a clean client, with no injected code and no mod menu. To behavioural detection it does not look like cheating, because technically it is not. It is your resource doing what you told it to do.

What we see most often on servers that keep getting hit is not a missing anti cheat. It is one free script pulled off a forum with an open money event in it.

Before you install anything, go through every server-side file:

• Search your resources folder for RegisterNetEvent and RegisterServerEvent and write down every event a client can reach.
• For each one, confirm the handler re-checks the source server-side: does this player actually have that job, that item, that balance, that permission?
• Never trust a value passed from the client as a quantity, a price, or an identifier. Look it up server-side from the source.
• Delete or rewrite events that only exist for debugging, admin testing, or a feature you stopped using two updates ago.
• Move anything authoritative, such as inventory changes, payments, and vehicle spawning, out of client-side logic and into the server.

It is tedious, and in our experience the highest-value work you will do on server security. It is also the step we see skipped most, which is why it comes first.

Step 2: Baseline server hardening

The anti cheat protects the game session. It does not protect the machine that session runs on. Do these first:

• Keep your FXServer artifacts current. Old artifacts carry known issues that have nothing to do with cheats.
• Give txAdmin and RCON strong, unique credentials, restrict panel access by IP where your host allows it, and keep licence keys, database credentials, and API tokens out of any repo or archive you hand a developer.
• Do not expose your database port to the internet. MySQL should listen on localhost or a private network only.
• Trim your admin list to people who currently need it. Dormant admin accounts are a real abuse path.
• Put DDoS mitigation in front of the server before you need it, not during the attack.

That last one matters because attacks land at peak hours, when you have least time to react. FairShield Gravity covers L3 to L7 mitigation across seven global locations, with Anycast routing, 449 Tbit/s of scrubbing capacity, automatic mitigation in under ten seconds, and zero-config DNS onboarding. Already mid-attack? Our guide on what to do when your FiveM server is under DDoS attack covers the immediate steps.

Step 3: Install and configure the FiveM anti cheat

With the audit done, the install is straightforward. Two things people get wrong.

Load order. Start the anti cheat early in your server.cfg, ahead of your gameplay resources. If it initialises after your framework, there is a startup window where detections are not running.

Identifier configuration. Decide which identifiers you enforce on before you go live. FairShieldAC works across HWID, IP, Steam, and Discord; setting that at install time means your first ban is enforceable rather than trivially bypassed.

Then connect the pieces: real-time web dashboard, Discord webhooks, txAdmin integration. FairShieldAC runs hybrid client-side and server-side heuristic behavioural detection, uses encrypted and shuffled event triggers against server-event spoofing, and includes a screenshot system with OCR verification, so you get evidence you can read in a ticket.

Step 4: Set detection sensitivity, and why starting strict backfires

Start strict on everything and your first week goes on apologising to real players. In our experience that is a common reason owners rip an anti cheat back out inside a fortnight. Split your categories in two.

Run strict from day one on the things with no innocent explanation: Lua executors, unauthorised code injection, and known mod menus such as Eulen, Susano, Ghost, TZX, Keyser, and Macho. A player's machine has no legitimate reason to be running any of that.

Run log-and-review first on the categories your own scripts can imitate: teleport, noclip, freecam, speed, and some vehicle spawn behaviour. Job scripts teleport players. Admin tools use noclip. Watch a week of real traffic, see which of your resources trigger flags, whitelist or fix those, then tighten.

A week of logging costs little. A wave of false bans costs you players you will not get back.

Step 5: Wire Discord and the dashboard so staff see detections

A detection nobody reads is not protection. Set it up as three destinations, not one firehose channel:

• High-confidence actions (executor, injection, known menu) into an alerts channel staff have notifications on.
• Ambiguous detections into a review queue one named person checks daily.
• System and status messages into a quiet channel, so real alerts never get buried.

Keep all three admin-only. Cheaters read your public Discord, and a visible detection feed tells them which of their tools is caught. Screenshot and OCR evidence arrives with the alert, so staff decide from evidence rather than an argument in a ticket.

Step 6: Define your ban policy before you need it

Write this down while nothing is happening. Deciding policy at 2am with an angry player in your tickets produces calls your staff cannot defend later. Decide, in writing:

• Which categories are automatic and permanent, and which get a human review first.
• Which identifiers each ban enforces on. Steam and Discord accounts are cheap to replace, which is why hardware-level enforcement matters; see our explainer on how HWID bans stop repeat cheaters.
• Whether the ban propagates to the global ban network, blocking that player across every server on it.
• How long you keep screenshot and log evidence.
• Who handles appeals, on what channel, and what evidence overturns a ban.

Step 7: Test it before you announce it

Never test on live. Spin up a development server with the same resource set and confirm:

• A test detection fires end to end, from trigger to Discord alert to dashboard entry.
• A ban actually blocks reconnection, including from a fresh account on the same machine.
• Your admin tools do not flag your own staff.
• Performance holds under a populated test. Our own measurements put FairShieldAC tick latency between 0.01ms and 0.06ms; verify it on your hardware rather than take any figure on faith.
• Members Lookup returns what you expect for a known identifier, so staff can pre-screen applicants at lookup.fairshieldac.com.

Common FiveM anticheat setup mistakes

What to review every week

Setup is not a one-time task. Your server changes and so do the cheats. A short weekly review is enough:

• Detections versus confirmed bans. A widening gap means a category needs tuning.
• Any category producing repeat false positives on the same resource.
• New resources added since last week: did they get event-audited before going live?
• Open appeals, plus anything overturned and why.

Between reviews, the warning signs a cheater is on your FiveM server usually show up in player reports before they show up in logs.

What this setup will and will not do

Done in this order you get layered coverage: a hardened host, validated server events, behavioural detection on client and server, usable evidence, and bans that carry across the global ban network.

What it will not do is catch everything. No anti cheat does, and anyone telling you otherwise is selling. Cheat developers update, new menus appear, and there is always a gap between a new technique and its detection. We keep that gap short with behavioural detection rather than signatures alone, which is why detection tends to survive cheat updates, and why the three layers of protection back each other up.

The honest summary: an anti cheat catches the players attacking your server. Your event validation decides whether attacking it is worth their time. Get the second right and the first has far less work to do.
