I like that when using this software, it will tell me if my site has been hit or not with any kind of update.
It also allows us to find issues in our content that we were unaware of. The only thing about Barracuda that I dislike is they can be expensive for smaller companies who don't have as much traffic as bigger ones - so you need to make sure you plan ahead before purchasing! This isn't something everyone needs but it really helps out those who do! We've found several things through their service that we weren't aware of before and some are just small, little issues which could add up over time to give big results if addressed properly.
