Earning the Certified Information Systems Security Professional (CISSP) credential is one of the most impactful moves you can make in your information security career. But for many professionals, the biggest challenge is time. Between work commitments, personal responsibilities, and the vastness of the CISSP syllabus, preparation can feel overwhelming.
The good news? With the right strategy and discipline, you can pass the CISSP in just 90 days — even while working full time.
Why the 90-Day Plan Works
This approach focuses on consistency, active recall, and smart prioritization. Instead of trying to memorize every detail, you’ll focus on:
- Understanding core concepts
- Applying knowledge through practice questions
- Reviewing high-yield topics multiple times before the exam
The CISSP 8 Domains
Before diving into the schedule, remember CISSP covers the following domains:
- Security and Risk Management
- Asset Security
- Security Architecture and Engineering
- Communication and Network Security
- Identity and Access Management (IAM)
- Security Assessment and Testing
- Security Operations
- Software Development Security
90-Day Study Plan
Phase 1: Foundation (Days 1–30)
Goal: Understand all 8 domains at a conceptual level.
- Enroll in our bootcamp.
- View 1-2 hours of the bootcamp recording to revisit the concepts.
- Make summary notes in your own words.
- End each week with a 20–30 question quiz from that week’s topics.
Phase 2: Deep Dive & Practice (Days 31–60)
Goal: Strengthen weak areas and start heavy practice.
- Attempt 50–75 practice questions daily using our or any reputable question bank.
- Review explanations for every question — even the ones you got right.
- Dedicate extra time to domains where your quiz scores are below 70%.
Phase 3: Exam Simulation & Final Review (Days 61–90)
Goal: Build exam stamina and sharpen recall.
- Attempt full-length practice exams (125–150 questions) twice a week.
- Focus revision on frequently tested topics and high-value concepts.
- Use flashcards for quick recall in spare moments.
- In the last week, avoid learning new material — only revise and rest well.
Pro Tips for Success
- Stick to the schedule — even short daily sessions matter more than long, irregular study days.
- Learn to think like a manager — CISSP is about decision-making, not just technical depth.
- Understand, don’t memorize — the exam rewards comprehension over rote learning.
- Simulate real exam conditions — time yourself and practice sitting through long tests.
