I've been getting the advertisements for the CCSP certification and it looks interesting but a fellow CISSP suggested getting the CCSK or other certification from a different provider because of the additional CPE requirements. According to him, with the CISSP and CCSP, one cannot “double-dip,” i.e., apply the same course to both certifications' requirements as one can with the CISSP and a certification from a different provider. On the other hand, I've read in a different thread that up to 30 hours of courses taken in pursuit of the CCSK can be counted towards the CPE requirements for the CISSP. What experiences have others here had with satisfying the CPE requirements for multiple certifications from the same or different providers?
CCSK then head to CCSP is a nice journey. I got CCSK first and then proceeded with CCSP with limited study guide and info. However, the knowledge I got with CCSK did help. Just my $0.02.
I passed the CCSP in March of this year. I used the CCSK materials to study for the CCSP. I don't think you need both the CCSK and the CCSP, but I think the CCSP will have a greater following in time.
