First of all thanks for using this program, now that you have installed it you can expand and/or secure it a little better.

Securing:
Although the hacksuite isn't created to be a secure environment with admin and other priviliges you can however restrict access to one or more ip-addresses. Click on the ip access menu, if you haven't set your ip address yet, you can now.


Expanding:
If you're using the hacksuite to brute force targets, you might want some extra wordlists, which you can find here:
wordlists

You can use any wordlist that has words on separate lines.

Everything else you need is already in the package or can be created with the suite itself.
