If you have time pls read the hole report here:

I hope that Untangle staff already has seen this report and that we can push the SSL/TLS parts of Untangle to an even better solution.
It will take time and $ but it will be worth it if we can beat cisco and i think it is in reach!
But still Amazing that Untangle is on the list!
