No exitWhile your network firewall or security software typically allows you to receive course data, they might erroneously block your browser from sending data back to our server - keeping you so "safe" you can't use your course. If you experience unexpected behavior such as the failure to record course progress and scores (such as your browser attempting to send progress data back to our server), course "freezing", or other erratic behavior, please be sure to configure certifiedinfosec.com as a "trusted site" so that no course communication is blocked or filtered.
