Port scans prevention

The protection of your device's ports is activated natively and by default. The blocking is done to prevent websites from checking for open ports on your system.

Among the blocked ports are the following: **8000, 3389, 5900, 5800, 7070, 6568, 5938, 5901, 5902, 5903, 5279, 5931, 5939, 5944, 5950, 6039, 6040, 6333, 63333**

Understand how it works

In more technical terms, a port is a communication endpoint. When an application is running on the computer, it opens a port. This port acts as an address with which applications can interact with each other.

About port scanning

Websites, using local port scanning through WebSockets, can see which ports are open on a particular computer and, as a result, understand which program our users are running. According to data studies, sites like Facebook, eBay, or Amazon use this fingerprinting method, although it is illegal in some countries and a gray area in others.
