Security+ vs CISSP: Which Cert Is Right for You?

If you're deciding between Security+ and CISSP, here's the straight answer: they're not really competitors. CompTIA Security+ is an entry-to-mid level certification for early-career professionals, while CISSP is a senior-level credential for experienced security leaders. Most people who pursue CISSP later in their career actually start with Security+ first. The real question isn't which one is "better"—it's which one is right for where you are now in your career.

This guide breaks down the key differences so you can make the right choice for your situation.

Security+ vs CISSP at a Glance

Here's a quick side-by-side comparison:

Feature	Security+	CISSP
Issuing Body	CompTIA	(ISC)²
Career Level	Entry to mid-level	Senior/management
Experience Required	2 years recommended	5 years required (2+ domains)
Exam Duration	90 minutes	Up to 4 hours (adaptive)
Number of Questions	90	100–150
Passing Score	750/900	700/1000
Validity Period	3 years (CE required)	3 years (CE required)
Exam Cost	~$404	~$749

Both certifications are well-respected across the industry and especially valued for government and defense roles. But the requirements and scope tell the real story about which one fits your career stage.

Experience Requirements: The Main Barrier

The most significant difference between Security+ and CISSP is the experience requirement, and this is often the deciding factor.

Security+ recommends 2 years of IT administration or security experience, but CompTIA doesn't enforce this—you can technically take the exam with no experience at all. Many employers see it as the first real security credential, ideal for people transitioning into security roles from IT support, network administration, or help desk positions.

CISSP requires a minimum of 5 years of professional information security work experience in at least two separate security domains (like access control, cryptography, or security operations). This is a hard requirement enforced by (ISC)². You can't bypass it. If you don't have the experience yet, you're not eligible to become CISSP-certified, period.

This single requirement is why Security+ and CISSP are in different career brackets. CISSP assumes you've spent half a decade building real-world security knowledge. Security+ assumes you're just starting that journey.

Difficulty: Knowledge vs. Judgment

Both exams are challenging, but they test different things.

Security+ is a knowledge-based exam. You need to understand security concepts, practices, and tools. The questions are mostly straightforward: "What is the primary purpose of a firewall?" or "Which encryption algorithm is considered the strongest?" You can pass by studying hard and understanding the material well.

CISSP is a judgment-based exam. It assumes you have the foundational knowledge and tests your ability to make decisions as a security leader. Questions focus on scenarios and strategy: "Your organization has 500 endpoints across three continents. What's the most cost-effective security architecture?" You need real-world experience to answer these well because they require professional judgment, not just technical knowledge.

CISSP is significantly harder. The average first-time pass rate for Security+ is around 65–70%, while CISSP's is closer to 30–40%. Experienced professionals often spend 3–6 months studying for CISSP even though they already know the foundational material. The breadth is wider, and the depth goes much further.

Career Paths: Where Each Cert Takes You

Your certification shapes the roles you're competitive for.

With Security+:

Security Operations Center (SOC) analyst
Information security specialist
Security administrator
Junior penetration tester
IT security analyst
Compliance officer (entry-level)

These roles typically pay $50,000–$95,000 depending on location, company, and experience.

With CISSP:

Security manager
Security architect
Chief Information Security Officer (CISO)
Senior security consultant
Risk management director
Governance and compliance manager

These roles typically pay $120,000–$160,000+ depending on experience and location.

The salary difference is real, but it's important to recognize that CISSP holders have 5+ years of security experience built in. The salary premium reflects both the credential and the experience required to earn it.

Salary Impact: What You'll Actually Earn

Let's talk numbers.

Security+ certification holders typically earn between $75,000 and $95,000 annually. In major tech hubs like San Francisco, New York, or Seattle, you might see $85,000–$110,000. Entry-level security roles with this cert average around $60,000–$75,000, while mid-level roles push toward $100,000.

CISSP certification holders typically earn between $120,000 and $150,000+. Senior security manager and architect roles can reach $150,000–$200,000+. The salary floor is significantly higher.

However, here's the nuance: CISSP candidates have 5+ years of security experience. Someone with 5 years of experience in security roles (with or without CISSP) will earn more than someone with 2 years of experience. The difference in salary comes from both the credential and the experience level it requires.

What does this mean for you? If you're early in your career, Security+ gets you into the field and positions you for a $70,000–$90,000 range. Five years later, with that experience, CISSP (if you pursue it) can push you toward the $120,000–$150,000 range.

Difficulty Comparison: CISSP Is Substantially Harder

Beyond the format differences, here's why CISSP is considered harder:

Breadth: Security+ covers 8 main domains over about 1,500 pages of study material. CISSP covers 8 domains plus advanced topics across roughly 3,000+ pages. You're expected to master more material.

Depth: Security+ explains concepts. CISSP assumes you understand the concepts and focuses on how to apply them strategically. Example:

Security+: "What is role-based access control (RBAC)?"
CISSP: "Your organization has 15 separate business units with overlapping needs. How would you design an RBAC system that scales?"

Experience assumption: You can study for Security+ from books and online courses. To prepare well for CISSP, you need to apply your studying to actual work situations. If you don't have that real-world context, the exam becomes much harder because scenario-based questions don't make as much sense to you.

Adaptive testing: Security+ is linear. CISSP is adaptive—if you answer questions correctly, they get harder. If you struggle, they adjust. This makes it harder to coast on partial knowledge.

Most security professionals who pursue CISSP spend 200–300 hours studying, even with years of experience. Security+ typically requires 100–200 hours.

DoD and Government Security Roles

Both certifications are valuable for government and defense work, but they fill different levels.

Security+ satisfies DoD 8140 Information Assurance Technical (IAT) Level II requirements. This opens doors to entry-to-mid-level government security positions, many of which are significant stepping stones in your career.

CISSP satisfies DoD 8140 IAM (Information Assurance Management) Level III requirements. This is the certification for managers and senior practitioners in government security roles.

If government security work is part of your career plan, both are valuable. Security+ gets your foot in the door. CISSP gets you into leadership and management roles.

The Recommended Career Path for Most People

Here's what we see most often among successful security professionals:

Early career (0–2 years in IT): Get your foundational IT knowledge through CompTIA A+, Network+, or hands-on IT support roles.
Transition to security (2–3 years): Pursue Security+ while working in security-adjacent roles (network administration, IT support with security focus, help desk).
Build security expertise (3–5 years): Work in SOC analyst, security administrator, or junior security engineer roles. Deepen your knowledge in specific domains.
Senior roles (5+ years): With 5+ years of documented security experience, pursue CISSP to move into management and architecture roles.

This path makes sense for a few reasons:

Security+ validates your knowledge when you're entering the field, making you competitive for better roles faster
You spend years building the real-world experience that makes CISSP study actually make sense
By the time you pursue CISSP, you have context for everything the exam covers
The salary growth is consistent and logical

When to Skip Security+ and Go Straight to CISSP

There's one scenario where Security+ doesn't fit: if you already have 5+ years of documented security experience.

If you've spent the last 5 years working as a security analyst, security engineer, security manager, or similar role—even without Security+—you might skip directly to CISSP. You have the experience, and your resume might be stronger with CISSP than Security+ at this point.

However, even experienced professionals sometimes get Security+ first if:

Their previous roles were informal or freelance and might not be recognized by (ISC)²
They want quick validation to build credibility in a new organization before pursuing CISSP
They're transitioning from IT into security and want a clear "entry-level" credential on their resume

But if you genuinely have 5+ solid years in security roles, you can go straight for CISSP.

Which One Should You Get?

Get Security+ if:

You're early in your IT or security career (0–4 years)
You're transitioning from IT into security
You want a recognized credential to boost your resume now
You need DoD 8140 IAT Level II compliance for a role
You want the foundational knowledge before pursuing CISSP later

Get CISSP if:

You have 5+ years documented security work experience
You're ready to move into security management or architecture roles
You want to position yourself for senior roles and higher salaries
You meet the (ISC)² experience requirements (5 years in 2+ domains)
You need DoD 8140 IAM Level III compliance

Get both (in order) if:

You're just starting in security and planning a long career in this field
You want both the entry-level validation (Security+) and the senior credential (CISSP)
