CPUG: The Check Point User Group

Resources for the Check Point Community, by the Check Point Community.


I'd like to thank everyone involved for making "The CPUG Challenge" a great success.
We helped a lot of people see and learn a bit more about R80.10, while having some fun.
We will be using this success to try and bring more events to more locations soon. -E
