Client Isolation

Client isolation is a network security feature that is designed to prevent devices on a shared network from communicating directly with each other. It is commonly used in public Wi-Fi networks, such as those found in airports, hotels, and coffee shops, to prevent unauthorized access to other devices on the same network.

When client isolation is enabled, each device on the network is isolated or “quarantined” from the others, preventing them from exchanging data or communicating with each other directly. This means that a device on the network can only communicate with the access point or router, but not with other devices connected to the same access point or router.

Client isolation can help to prevent security risks such as man-in-the-middle attacks, where an attacker intercepts and modifies data transmitted between devices on the same network. It can also help to protect users’ privacy by preventing other users on the same network from accessing their personal information or sensitive data.

However, it is important to note that client isolation can also limit functionality in some cases, such as in situations where devices on the network need to communicate with each other for a specific purpose. In these cases, it may be necessary to disable client isolation or configure exceptions to the isolation rules to allow for the necessary communication.
