Start guided practiceISC2 Certified Information Systems Security Professional
The most widely recognised senior security certification: eight domains spanning risk management, asset and architecture security, networks, identity, testing, operations and software security.
ISC2 does not publish numeric exam codes — CISSP is the common abbreviation.
ISC2 Certified Information Systems Security Professional is ISC2's expert-level cybersecurity certification, referred to across the industry by the shorthand CISSP. The exam runs for 4 hours and presents up to 150 questions, with a pass mark of 700 / 1000 (scaled, adaptive). It costs US$749 at the standard rate.
ISC2 publishes the syllabus as 8 weighted domains. Security and Risk Management carries the most weight at 16%, and the three largest domains together account for roughly 42% of the scored content — worth knowing before you decide where study time goes.
CISSP is adaptive, so the number of questions you see depends on how you answer. It is also deliberately management-oriented — the expected answer is usually the one a security leader would give, not the most technically clever option.
Confirm these details on the official ISC2 page before booking — vendors adjust format and pricing without notice.
