There are so many out there it’s hard to sift through. I have narrowed things down to 4:
1. Ipfire
2. Astaro
3. Untangle
4. Comixwall
Depending on capabilities and budget those are the 4 ECC is going to be choosing from for the foreseeable future. This makes it easier for my clients to know what i am offering and makes it easier for me since i’m not suporting 10 different server packages. I intend on narrowing it down to 2 in the near future.
