It's free! I like how easy it is to install/configure in your environment. You don't have to be an expert techy person if you're not familiar with Linux or Apache servers (like me). And there are some great tutorials online too so this isn't as scary of learning curve as other software out there. The only thing i dislike about hiwatah webservers is they dont host many websites at once but I'm sure its because our IT department doesnt want us hosting more than 3-4 sites but thats something we need to work through their side. We've been able to use this product along side Sharepoint 2013 which has really helped improve security across multiple environments within my organization since most people here do not know much linux stuff nor apache configs.
