How Hard Is CISSP? - Global Times Network

When I first heard about the CISSP certification, the reactions were mixed.

Some said it was a career-changing credential; others warned it was one of the hardest exams in IT. Naturally, I had to find out for myself. If you’re wondering, “How hard is CISSP?” — you’re not alone. Whether you’re new to cybersecurity or a seasoned professional, this question comes up a lot.

In this post, I’ll share what makes the CISSP hard (and manageable), who it’s for, and how you can set yourself up for success.

First, What Is CISSP Really About?

The Certified Information Systems Security Professional (CISSP) is a certification from (ISC)², designed for experienced cybersecurity professionals.

It’s not entry-level. In fact, you need 5 years of experience in at least 2 of the 8 CISSP domains, which include:

Security & Risk Management
Asset Security
Security Architecture & Engineering
Communication & Network Security
Identity & Access Management
Security Assessment & Testing
Security Operations
Software Development Security

The CISSP is recognized globally and often required for senior-level roles like Security Manager, CISO, or Security Architect.

So, How Hard Is the CISSP Exam?

Let’s just say: it’s no joke.

✅ It’s Hard Because It’s Broad

The exam covers a vast amount of material. Each of the 8 domains is deep enough to be a subject on its own. That means you’re not just studying security—you’re learning policy, law, operations, networking, risk management, cryptography, and secure software design.

✅ It’s Hard Because It’s Conceptual

CISSP questions are not straightforward. You’ll be asked to think like a security leader, not just a technician. You must evaluate situations, choose the best (not just correct) answer, and often deal with vague, scenario-based questions.

✅ It’s Hard Because It’s Adaptive

If you take the English version, you’ll face the Computerized Adaptive Test (CAT) format. The better you do, the harder the questions get. And once you answer a question, you can’t go back.

What’s the Pass Rate?

While (ISC)² doesn’t officially release pass rates, most industry experts estimate the CISSP pass rate to be around 55–60% on the first attempt.

That means roughly 4 out of 10 people fail. Not because they’re not smart, but because the exam demands focus, strategy, and serious study.

My Personal CISSP Study Journey

I studied for about 4 months, putting in:

~1 hour a day during weekdays
3–4 hours on weekends
Around 120 total hours of focused study

Here’s what worked for me:

📚 1. Books I Used

Sybex CISSP Official Study Guide
Eleventh Hour CISSP for revision
CISSP practice questions from Boson and CCCure

💻 2. Online Courses

I found the Thor Pedersen CISSP course on Udemy extremely helpful for explaining complex topics in a simple way.

📋 3. Practice Tests

I cannot stress this enough: practice tests are crucial. They teach you the question style and help identify weak areas.

Who Should Attempt the CISSP?

Before asking “how hard is CISSP?”, first ask:

Am I ready for this?

CISSP is best suited for:

IT professionals with 5+ years of experience
Security analysts or engineers looking to move into management
Professionals seeking roles like CISO, Security Consultant, or Architect

If you’re just starting out, certifications like CompTIA Security+, SSCP, or CEH may be a better starting point.

Top Reasons Why People Fail the CISSP Exam

Underestimating the scope
Over-focusing on technical knowledge (and ignoring governance/policy questions)
Not enough practice with CISSP-style questions
Memorizing facts instead of understanding principles
Studying sporadically without a consistent schedule

How to Make CISSP Easier (Or at Least More Doable)

✅ Create a Study Plan

Break the syllabus into weekly chunks. Focus on one domain per week. Review frequently to avoid forgetting what you’ve already studied.

✅ Think Like a Manager

CISSP questions are often about what’s best for the organization, not just what’s technically accurate. Choose answers that emphasize risk management, policy, and user safety.

✅ Join Study Groups

You’re not alone! Join Reddit’s r/CISSP, Discord channels, or LinkedIn study groups to discuss tough concepts and stay motivated.

✅ Use Flashcards

Flashcards are great for memorizing key concepts, acronyms, and definitions. Apps like Anki or Quizlet can help.

Is the CISSP Worth the Effort?

Yes—100%.

While it’s a tough exam, the benefits are enormous:

💼 Career Growth

CISSP is a gateway to senior-level security roles and often required for government and DoD positions.

💰 Higher Salary

CISSP-certified professionals earn an average of $120,000+ annually (according to numerous salary surveys).

🌎 Global Recognition

Whether you’re in the U.S., India, UAE, Canada, or Europe, CISSP is respected globally.

Common Questions: How Hard Is CISSP?

❓ Can I pass the CISSP in 3 months?

Yes—if you have relevant experience, are consistent, and follow a smart study plan. Otherwise, aim for 4–6 months.

❓ What’s the hardest domain in CISSP?

Many candidates find Security & Risk Management or Security Architecture & Engineering to be the most challenging.

❓ Is CISSP harder than CEH or Security+?

Yes. CISSP is far more comprehensive and managerial in nature. It’s more strategic and conceptual compared to technical certs like CEH.

Final Thoughts

So, how hard is CISSP?

It’s tough. But it’s also doable—with the right mindset and preparation.

It’s not about being a genius. It’s about being disciplined, strategic, and consistent. If you put in the time, use the right resources, and stay focused, you’ll be among the thousands who proudly add “CISSP” after their name.

If I can do it—you can too.
