Difficulty Comparison: CISSP vs CISA
When comparing difficulty, the CISSP is rated very hard while the CISA is considered hard. This difference reflects the depth and breadth of knowledge each exam tests.
The CISSP exam consists of 100–150 (adaptive) questions with a passing score of 700/1000. Candidates typically need 3–6 months study of dedicated preparation to feel confident on exam day.
The CISA exam features 150 questions with a passing threshold of 450/800. Most candidates invest 3–6 months study in preparation, though this can vary based on prior experience and study habits.
Both exams reward consistent, structured study. Practice tests are particularly valuable for building familiarity with question formats and identifying knowledge gaps before test day.
Salary and Career Outlook
Career earnings are a major factor when choosing between certifications. CISSP holders can expect to earn $110,000–$150,000 annually, while CISA credential holders typically earn $85,000–$120,000.
These figures represent national averages and can vary significantly based on location, years of experience, industry sector, and additional certifications held. Metropolitan areas and specialized roles often command premium salaries.
Beyond base salary, consider the long-term career trajectory. Some certifications open doors to management roles, specialized positions, or consulting opportunities that can significantly increase earning potential over time.

Which Should You Take First?
For most professionals, starting with CISA is the recommended path. It provides foundational knowledge with a more accessible entry point, preparing you for the more demanding CISSP certification.
With your CISA credential in hand, you can gain practical experience that makes the CISSP study material more concrete and manageable. Many successful professionals follow this progression.
That said, experienced professionals with strong backgrounds may choose to pursue CISSP directly, especially if their career goals require the advanced credential sooner.
