How to stop speed hackers on your FiveM server
Speed and teleport hacks are the clearest-cut cheats there are: when a player moves faster than the game physically allows, there's no innocent explanation. That makes them the ideal case for automatic banning — and BlackGuard catches them server-side, where the cheat can't hide.
Why speed hacks are safe to auto-ban
Most cheat signals are judgment calls. Impossible movement isn't. A player covering more ground in a tick than any vehicle could, or sprinting at highway speed on foot, is doing something the game's physics rule out entirely. Because there's no legitimate way to produce it, BlackGuard can ban it automatically with almost no false-positive risk — which is exactly why speed and teleport are deterministic auto-ban detections rather than flag-for-review ones.
How BlackGuard detects it — server-side
BlackGuard measures each player's movement against the server's authoritative position and velocity, not a value reported by the player's machine. A speed or teleport hack changes what the player does, and the server sees it directly — so the detection can't be patched or spoofed from the client the way a client-side check can. Thresholds are set above every legitimate in-game speed — the fastest cars, sprint, and normal boosts all stay comfortably under the line — so real players are never caught, and physically-impossible movement is banned the moment it happens.
Speed is just one category. For the gray-area exploits that shouldn't be auto-banned, BlackGuard flags instead — see how it handles money exploits, the full guide to stopping cheaters, or pricing — every detection on every plan.
FAQ
What is a speed hack on FiveM?
A speed hack makes a player or vehicle move faster than the game physically allows — sprinting at car speed, driving at impossible velocity, or covering ground no legitimate movement could. Closely related is the teleport hack, where a player's position jumps an impossible distance in a single tick. Both are movement cheats, and both are detectable from the server.
Does BlackGuard auto-ban speed hackers?
Yes. Impossible speed is one of BlackGuard's deterministic auto-ban detections. Because movement is measured server-side against what's physically possible, a player moving faster than any legitimate vehicle or animation allows is caught and banned automatically — no manual review needed, because there's no innocent explanation for physically-impossible speed.
Will it false-ban my players in fast cars or with legit speed boosts?
No. The thresholds sit above every legitimate in-game speed — the fastest vehicles, sprint, and normal boosts all stay well under the line. Auto-bans are reserved for movement that is physically impossible, where a false positive is extremely unlikely. The guiding rule is that a wrongly-banned real player is worse than a missed cheater, so the bar for an automatic ban is deliberately conservative.
What about teleport hacks?
Teleporting is handled the same way: BlackGuard measures position change per tick from the server's authoritative state, and an impossible jump is auto-banned. Because the server knows where a player truly is, a teleport can't hide from it the way it might from a client-side check.
Does speed detection run on my framework?
Yes. Movement detection — speed and teleport — is part of the core engine and runs on ESX, QBCore, QBox, vRP, and standalone servers. It's server-side, so there's nothing on the player's machine to bypass.
