Sayed,
The answer would this would be highly dependent on your budget for the project and after that would be a question of which protection equipment you determine to do the job for you. One of the great features of HAMMER and our other software is that you can take advantage of using scenarios so you can test multiple protection devices and determine, which offers the best protection for your system for the best price.
Since you are new to the sofware if you haven't done so already you should probably go through the quick start lessons in the help documentation. You might also want to have a look at our HAMMER V8i wiki technotes on this page:
