How to prevent a player from entering an unauthorized area?

Looking better, I found a solution based on this answer:

How do I accurately check if a player is in a certain area?

You can use an invisible part and whenever you want to test if the player is in the certain area use part:GetTouchingParts() and check if the player’s HumanoidRootPart is in the dictionary it returns. Hope that helped! Edit: Don’t forget to assign a .Touched event that does nothing so a TouchInterest will be in the Part Edit 2: Code Example local Part = script.Parent Part.Touched:Connect(function() end) -- Just for a TouchInterest to occur on a CanCollide false part function CheckIfPlayerIs…

Creating invisible parts surrounding the unauthorized area and triggering the event BasePart | Roblox Creator Documentation, it is possible to test which player touched this part and prevent him from advancing to in there.
