I was planing to take this cours in future so i wana know one think.
How long is this certificat valid,is it limited on some time so i need to do it again after maybe 2-3 year or i do it once and its stay valid always?

 

The ISC2 CPE credits go toward maintaining CISSP, for those who have it.  There is a requirement for CISSP's to obtain a certain amount of CPE credits to stay valid.  (I don't know the number and specifics offhand, as I'm not a CISSP (it's on my list of things to do, but time.....)

I know ISC2's website has all of the CPE details.

Hope that clarifies a bit.
