It monitors the logs on your server and detects failed logon attempts. If the number of failed logon attempts from a single IP address reaches a set limit, the attacker's IP address will be blocked for a specified period of time.

Why do you need it?
Many Windows Server machines are under constant attack. Network scanners and RDP brute-force tools work 24/7. Eventually they may find a password to access your server! Moreover, RDP brute-force attacks abuse server resources (CPU, RAM, Disk Space and Network Bandwidth).
Take a look at your server's Security EventLog. How many failed login attempts do you see? The log may note thousands of failed login attempts from a single IP address. This means that someone is trying to find a password to access your server.

How can you protect your server from brute-force password-guessing attacks on RDP? The answer is RdpGuard - powerful tool that allows you to protect your Remote Desktop from brute-force attacks.
RdpGuard works as a Windows Service. Your Windows Server will be protected even if nobody is logged in.
