After using Abyss Guard on my server for just a few months I have been able to greatly reduce "bad bot" traffic, recognize weak points in some of my own code and see how many attempts there are at hacking into our sites (scary) and take action to defend against them. This is a great addition to my security tools! This is a must have tool for anyone managing a server and site/s and cannot afford the monthly expense of a 3rd party doing this for you. Great job!
