How does IP Muncher improve your security?
IP Muncher is an intrusion detection software that is continuously monitoring for dictionary attacks against your servers. It can automatically configure the built-in windows firewall to block attacking IPs.

Protect RDP
Monitor Windows event logs for dictionary attacks against your RDP services. Immediately block the remote IP after X number of failed requests.

Protect SQL Server
Monitor Windows event logs for dictionary attacks against your SQL Server. Immediately block the remote IP after X number of failed requests against your SA account.

Protect Your Mail Servers
Are your mail servers getting dictionary attacked? Do they output generic log files containing the attacks? If so, IPMuncher can monitor those log files for the attacking IP.
Fail2Ban for Windows
If you are coming from a non-Windows world, you can think of IPMuncher as a fail2ban for Windows.
