SEC505 is the gold standard of Windows security training.

The best Windows security course I've attended in 25 years of administering Windows environments. Every time I pick up one of my GCWN books, I learn something new that's immediately applicable to my current situation. A must-have course for any system administrator who is serious about securing their environment.

You have the best instructors available. Other training never comes close and is a waste of money.
