CISSP vs CISM

CISSP and CISM overlap in subject matter but differ sharply in orientation. Neither is strictly "harder" or "better" -- they validate different things.

	CISSP	CISM
Issuer	(ISC)²	ISACA
Orientation	Broad technical + governance, generalist	Management and governance of the program itself
Domains	8, relatively even weighting	4, concentrated in program/incident management
Best fit	Security architects, engineers moving into leadership, broad practitioners	Security managers, program leads, CISO-track candidates
Experience required	5 years across 2+ domains	5 years, 3+ in security management

How to choose

If your work still touches technical architecture, network security, or hands-on assessment regularly, CISSP's breadth maps better to your day-to-day. If your work is primarily about running the program -- budget, policy, executive reporting, risk governance -- CISM maps more directly to what you actually do. Many senior GRC and CISO-track professionals eventually hold both; neither replaces the other.
