RdpGuard enables you to protect your Remote Desktop (RDP) connection from password-guessing brute-force attacks. It monitors the Windows EventLog for failed login attempts and if the number of failed logins from a single IP address reaches a set limit, the IP address will be blocked with a custom rule in the Windows Firewall.RdpGuard works in conjunction with the Windows Firewall and Eventlog, both these services must be running.
