The most useful part of this product for me personally was its ability to monitor all my internet activity at once without needing any additional programs or tools; it's very easy in use as well! I also love how customizable everything can be - you get so many options with different features (firewall rules) which are great when trying things out before deciding what works best within your business needs/requirements.- It could definitely benefit from some more bells & whistles added such as being able to set up multiple profiles per computer etc., but nothing too major has come across yet either way because everyone likes their own customizations anyway :) Overall there isn't anything bad about using cacheguard overall since i've seen no problems thus far other than maybe having issues if running certain applications alongside eachother due to resource conflicts between them? But just go ahead anyways unless.
