INDEX

Instead of trying to constantly blacklist bad IP addresses, DMZGuard blacklists everyone and whilelists only one authorized remote IP address, meaning all of your services are invisible to everyone but you. On the server version, you can whitelist more than one IP at the same time.
Multi-Factor security built-into DMZGuard ensures only you can demand to be whitelisted from the web interface.
Because DMZGuard runs on the PC being accessed, there are no 3rd party services involved, no privacy concerns, no other setup, and no fees.
Extremely simple setup and use for anyone.
Port level firewall control only allows services you want, like Remote Desktop and/or VPN.
Built in Apache Web Server and Tomcat App Server for you to run any other service.
100% open-source software!
