There are two blocking methods that you can choose from, either based on Windows firewall or on specific IP security policies. A list of exceptions can be defined to include addresses that are considered secure, regardless of the number of failed connection attempts. You can easily configure the maximum number of failed logon attempts that will trigger IP blocking and set the amount of time that an address will be kept on the blacklist (by default, 24 hours). Block IP addresses that repeatedly fail to connect Together with the Windows firewall, the RdpGuard security mechanism ensures intrusion prevention. It works as a Windows service, which means that the protection system is kept active even if there is no logged in client.

This ensures that remote desktops are protected against brute-force attacks and that your server is more difficult to break in. What this application actually does is constantly monitor the event log in order to detect consecutive connection attempts and immediately block the source IP address. RdpGuard is specifically designed to handle such situations, acting as a security layer for your server.

Repeated failed login attempts from the same IP address to a server might be a sign that someone is trying to guess the password and access the server without consent.
