"Should I get Security+ or CISSP?" is one of the most common career questions we hear from people moving into security. It's also slightly the wrong question, because the two certifications aren't competing for the same slot. They test different things, assume different experience, and open different doors.
Here's a plain comparison, followed by a decision guide you can apply to your own situation.
Security+: the practical foundation
CompTIA Security+ covers the core skills every security practitioner uses: threats and vulnerabilities, cryptography basics, identity and access management, network and application security, risk, and incident response. Its questions lean practical — including performance-based items where you work through a scenario rather than just pick an answer.
It doesn't have a formal experience prerequisite, though CompTIA recommends some networking and IT administration background. It's widely recognized, and it's commonly accepted as a baseline credential in government and defense contracting roles, which is one reason it shows up in so many job descriptions.
It fits best if you are: starting a security career, moving over from IT support or system administration, or in a role where you need to prove you understand security fundamentals.
CISSP: the breadth-and-judgment credential
The CISSP from ISC2 covers eight domains, including security and risk management, security architecture and engineering, identity and access management, security operations, and software development security. The questions reward thinking like a manager or architect: weighing risk, business impact, and policy, not just identifying the correct technical command.
Crucially, the full CISSP has an experience requirement — roughly five years of cumulative, paid work experience across at least two of the domains, with some allowances for a relevant degree or approved credential. If you pass without the experience, ISC2 lets you become an Associate while you accumulate it. Check ISC2's current requirements before you plan, since details can change.
It fits best if you are: an experienced practitioner moving toward security architecture, management, or consulting, or in a role where leadership credibility matters.
A simple decision guide
| Your situation | Likely starting point |
|---|---|
| New to security, coming from IT support or admin | Security+ |
| Several years in security, aiming for lead or architect roles | CISSP |
| In security already but without a formal certification | Security+ to fill foundations, then CISSP |
| Moving into security management from another discipline | Security+ first; CISSP once experience accrues |
| Hiring requirement names one explicitly | Whatever the requirement says |
The last row matters more than people expect. Check the actual job listings in the roles you want; they'll tell you what employers screen for.
Common mistakes
- Jumping straight to CISSP for the prestige. Without hands-on experience, the material stays abstract and the exam is considerably harder to pass.
- Treating Security+ as "too basic" to bother with. The fundamentals it tests are exactly what interviewers probe, and gaps there are obvious.
- Collecting certifications instead of skills. A certificate opens a door; what you can actually do keeps you in the room. Build a home lab or work on real projects alongside the study.
- Studying only from one source. Use official objectives as the syllabus, then practice questions and hands-on labs to find your weak areas.
A sensible study approach
- Download the official exam objectives and treat them as your checklist.
- Schedule the exam first. A date on the calendar beats open-ended intention.
- Study in short, regular sessions rather than occasional marathons.
- Mix reading with doing: set up a small lab, run a vulnerability scanner against it, practice reading logs.
- Take timed practice exams to learn the question style and expose weak domains, then revisit those.
What about the organization side?
If you're planning for a team rather than yourself, the useful question is which roles need which depth. A broad group of analysts and administrators benefits from Security+ level fundamentals; a smaller group of senior staff may need the CISSP's governance and architecture perspective. Mapping credentials to roles keeps training spend purposeful.
NovuSpark runs live, instructor-led programs for both: CompTIA Security+ Prep for the practical foundation and CISSP Certification Prep for the broader management-level material. If you're not sure where to begin, our Cybersecurity Fundamentals course is a good first step, and you can talk to us about the right path for your team.
