Are exploiters able to read local scripts? - Developer Forum | Roblox
Notice in the example above that the client only sends the name of the item ( "LaserBlaster" ). The client does not send the price. If the client sent buyItemEvent:FireServer("LaserBlaster", 0) , an exploiter could change that 0 to a negative number and exploit your system to give themselves infinite coins. Always store prices and critical logic on the server.
In a proper FE system, an "ESP" (Extra-Sensory Perception) script that shows players through walls usually only works for the user running the script. However, more advanced systems can make an ESP feature visible to a team or all players. This is achieved by the GUI, sending a request to the server to create a BillboardGui or highlight effect on a target player, which is then visible to all clients [16†L11-L14].
Scripts like "Fly GUI V3" or a walkspeed modifier also use this principle, but are typically for client-side use. Because the server controls character physics, these GUIs act as a "request" system. The GUI sends a signal to the server to adjust the player's Humanoid.WalkSpeed or to apply a body velocity, which then allows the character to fly or walk faster for all to see. roblox fe gui script

Critical Security Best Practices
Under FE, when something changes on the server, it replicates to clients; when something changes on a client, it does not replicate to the server or to other clients. This architecture means that any action that should impact the game world or other players must be validated and processed by the server.
TeleportRemote.OnServerEvent:Connect(function(player, zoneName) -- SECURITY CHECK: Is the zone valid? if allowedZones[zoneName] then -- SECURITY CHECK: Does the player have permission? (e.g., gamepass or role) if player:GetRankInGroup(123456) >= 1 then -- Group rank check local character = player.Character if character and character:FindFirstChild("HumanoidRootPart") then character.HumanoidRootPart.CFrame = allowedZones[zoneName] end else warn(player.Name .. " attempted to teleport without permission!") end end end) Are exploiters able to read local scripts

This is Roblox's standard security layer. It means that if you change your character's color in a LocalScript , only you will see it. To make others see it, you must use RemoteEvents to tell the server to make the change. Client vs. Server: Client (LocalScript): Handles your UI, input (keyboard/mouse), and local effects. Server (Script): Handles game logic, health, and data that everyone sees. 2. Essential GUI Components To build an FE GUI, you use various UI objects found in the StarterGui Developer Forum | Roblox ScreenGui: The main container for your on-screen menu.

Roblox development changed fundamentally with the introduction of Filtering Enabled (FE). This security feature dictates how data transfers between the client (the player's device) and the server. For developers looking to create interactive user interfaces, understanding how to write a proper is essential for creating secure, functional game elements. What is Filtering Enabled (FE)?
Here's the server script:
: A GUI is built using objects like ScreenGui , Frame , and TextButton . In an FE environment, the GUI itself exists on the client (StarterGui), but the "useful" buttons it contains often trigger server-side effects through those remote events.
