ISC2 CSSLP Exam Overview
What to Expect
The ISC2 CSSLP exam has 125 questions and a 190-minute time limit. That works out to about 1 minute and 31 seconds per question. You need to score 70% or higher to pass. ISC² exams use a scaled pass/fail model. CISSP requires 700 out of 1000 on the CAT format. The adaptive test can end as early as 100 questions (minimum) or continue to 150 (maximum) depending on your performance confidence level.
Testing and Delivery
ISC² exams are delivered through Pearson VUE. The CISSP uses Computerized Adaptive Testing (CAT) in all languages, which adjusts question difficulty based on your performance. Other ISC² exams use a standard linear format.
Certification Renewal
ISC² certifications require annual maintenance fees ($125 for CISSP, $50 for associate-level) and Continuing Professional Education (CPE) credits. CISSP holders need 40 CPEs annually with a total of 120 over the three-year cycle.

ISC2 CSSLP How to Prepare
Study Resources
The official ISC² study guides (Sybex) and the CISSP CBK are standard references. ISC² provides official training through authorized providers. The key to ISC² exams is thinking like a security manager, not a technician. They test judgment and risk-based decision-making above technical recall.
Preparation Strategy
Start by reviewing the official exam guide to understand exactly what's covered. Allocate your study time proportionally to domain weights: spend the most time on Secure Software Architecture and Design (15%) and work down from there. Most candidates need six to twelve weeks of focused preparation depending on their existing experience.
Hands-On Practice
Reading alone won't get you through this exam. You need hands-on experience with the technology. Set up a lab environment, work through practical scenarios, and practice until the concepts feel natural. The exam tests application of knowledge, not just recall.
ISC2 CSSLP Exam Day Strategy
Time Management
With 1 minute and 31 seconds per question, pace yourself from the start. Don't spend more than three minutes on any single question during your first pass. Flag uncertain questions and return to them after completing the rest. A wrong answer and a skipped answer score the same, so never leave a question blank.
Reading Questions Carefully
Pay close attention to qualifier words like "most," "best," "least," and "first." These words change the correct answer entirely. Read every option before selecting your answer, even if the first option looks correct. Exam writers intentionally place plausible distractors early in the option list.
