Three weeks after taking the CISSP exam, I received notification of a successful pass. Woo Hoo!

One thing that was very apparent to me was the information I learned while studying the CompTIA Security+ objectives definitively helped me with the CISSP.  The CISSP exam is a monster and will take a lot more time and effort to master than the Security+ certification.  However, if you take the time to truly learn the material for the Security+ exam, you'll be a step closer to the CISSP.

 As one of many examples, understanding public key cryptography helped with many questions on the CISSP exam.  Chapter 9 of the CompTIA Security+ SY0-201: Get Certified, Get Ahead book includes all of the material you'll need for cryptography in Security+ and you won't need much more if you later pursue the CISSP.
