CCNP Security expenses
I am wondering why CCNP Security path is so expensive? I mean the most cheapest one is regular CCNP. Everyone have to start with CCNA, progress to CCNP by taking 3 exams. Ok. However, for CCNP Security you would have to get CCNA, CCNA Security and then pass 4 (!) exams to get your CCNP Security. Much more expensive. And for example if you take CCDA and CCNA, then pass 3 exams for CCNP and one exams for CCDP (ARCH), then you get two certificates: CCNP and CCDP. Total cost is more than CCNP Security (not by much), but if you divide the cost per certificate it is actually way cheaper. So, why Security path is so expensive? I am also wondering is Cisco firewall is actually used so much around the world? Is it actually beneficial to study it? So far I have seen Checkpoint firewalls being used, but not Cisco.
