GlassWire is a powerful and multidimensional personal firewall and free network monitor tool. You can use it to constantly visualize your network and bandwidth usage with convenient graphs that can be stretched back to view past performance as well. The program provides real time and discrete notification on online threats including changes in network related files, ARP spoofing, proxy changes, DNS changes, host file changes and suspicious hosts. It also enhances user privacy by monitoring and censoring outgoing traffic. You can install the program on remote servers if you use it on a regular basis.
