(ISC)2 certification counts – how many CSSLP are out there?

(ISC)2 maintains this page https://www.isc2.org/member-counts.aspx# with the counts of all certifications per country.

I wrote before about this here https://www.sorinmustaca.com/how-many-certified-secure-software-lifecycle-professionals-are-out-there/, but this was back in 2013 (1.5 years after I became certified) !


Some statistics:

As of September 25 2013: 1168 CSSLP 

Romania  1

Germany 19


As of May 23 2022: 3008 CSSLP


Romania  6

Germany 48

Mexico 8





If these numbers appear big… look at the count of CISSP (without specializations): 152.623 as of today.

So, yes, you can see how hard is to get this certification.


This year I celebrate 10 years of being a CSSLP!
