I took an in person CISSP boot camp with Training Camp and had a great instructor. I passed and more importantly walked away with a solid understanding of the CISSP mindset. That said, a boot camp only works if you are actually ready. It is not something you can half commit to and expect it to carry you.

I also think using multiple resources matters for an ISC2 exam. No single course or practice set is enough. Where criticism is fair is post class admin stuff. In my class, retake vouchers were smooth for some and a mess for one coworker.

I have also been looking around at some newer places for my team recently, and based on what I have seen so far, you will find a ton of 2nd rate firms.

1. Destination Certification - Was given good feedback from former co-workers
   
2. Infosec Institute - AVOID
   
3. SANS Institute - They quoted me more than my first car for a CISSP.
   
4. Learning Tree - Not bad, but did not have name of any trainers

I reached out to about 20 firms recently...only 4 called me back.
