The CISSP (Certified Information Systems Security Professional) from ISC2 is one of the most respected certifications in cybersecurity. It is designed for experienced professionals who design, manage and oversee security programs. Here is what you need to know about requirements, content and preparation.
Who is CISSP for?
- Security managers, architects and consultants
- Senior security engineers and analysts
- IT directors and CISOs
- Auditors and GRC professionals
It is a management- and architecture-focused certification rather than a hands-on technical one.
Experience requirements
ISC2 requires cumulative, paid work experience in at least two of the eight CISSP domains (five years is the standard requirement, and a relevant degree or approved credential can waive one year). If you pass without enough experience, you can become an Associate of ISC2 and earn the full CISSP as you gain experience. You also need an endorsement from a current ISC2 member.
Exam details such as price, length and question count change periodically — always confirm current information on the official certification page before you book.
The eight CISSP domains

Exam overview
The English CISSP exam uses computerized adaptive testing (CAT), meaning the number of questions varies based on your performance. Questions emphasize judgment — choosing the best answer from a manager’s perspective.
How to think like a CISSP
Many candidates struggle because they answer like engineers. CISSP questions reward a risk-based, business-focused mindset:
- Safety of people comes first
- Align security with business objectives
- Prefer policies, process and governance before technical fixes
- Choose answers that address root causes
- Consider due care and due diligence
A 10–12 week study plan
- Weeks 1–8: Study one domain per week using an official study guide and video course
- Week 9: Review weak domains and summary notes
- Weeks 10–11: Practice questions focused on understanding explanations
- Week 12: Light review, rest and logistics
Study groups and flashcards help with the breadth of material.
