Most CISSP vs Security+ comparisons treat these like two options you'd pick between. They aren't. Security+ is what you take to get your first security job. CISSP is what you take five-plus years later when you're running security programs or close to it.
So the real question most people are actually asking — usually without realizing it — is: I have Security+. How do I know when I'm ready for CISSP? That's what this post is about.

Both are DoD 8140 baseline certifications. Both are well-respected. The important differences aren't in the table — they're in who each exam is written for.
Who Each Exam Is Written For
Security+ is written for someone who can describe what a firewall does, walk through how TLS works, and correctly identify a phishing email. The exam validates that you have the vocabulary and fundamentals to be useful in a Tier 1 SOC or junior analyst role. The PBQs push you a little into "can you actually do this," but mostly it's a knowledge exam.
CISSP is written for someone who's been in the room while security decisions got made. Not necessarily making them — but in the room. The exam doesn't really care whether you remember port 443 or the AES key sizes. It cares whether you'd recommend hiring a forensics firm or containing the breach in-house, and why.
This is where a lot of technically sharp people trip up on CISSP. I worked with a senior network engineer who had twelve years of hands-on experience and failed his first attempt. He was scoring mid-80s on practice tests. His issue: he kept picking the technically correct answer instead of the governance-first one. On a question about a discovered vulnerability, he'd pick "patch the system" when CISSP wanted "notify management and assess risk." He wasn't wrong in the real world. He was wrong on this exam.
Security+ asks, do you know how it works? CISSP asks, can you make the call?
The Experience Gate
This is the part most candidates underestimate.
Security+ has no experience requirement. You can pass it as a college student. CompTIA suggests two years of IT admin experience, but nobody checks.
CISSP requires five years of cumulative paid work experience across at least two of the eight domains. Holding Security+ earns you a one-year waiver, as does a relevant bachelor's or master's. That's as much as they'll waive — one year, regardless of how many credentials you stack. So the practical minimum is four years of qualifying security work before you can become a full CISSP.
You can still sit for the exam without the experience and become an Associate of (ISC)², then earn the credential as your experience accrues (up to six years). But the salary lift doesn't really show up until you've got the full CISSP after your name — employers aren't paying premium rates for the Associate title. The CISSP experience requirement has more nuance than most candidates expect, especially around what counts as a qualifying domain.
One pattern worth flagging: people who sit for CISSP too early, pass it as Associates, and then assume the job offers will roll in. They often don't — at least not at CISSP salary levels. Most of the time you'd have been better off waiting a year, earning an intermediate cert (SSCP, CySA+), and sitting for CISSP as a full candidate.
Difficulty, Honestly
Both exams are passable with focused study. They're not on the same planet.
Security+ is 4–8 weeks of study for most people with some IT background. The exam is 90 minutes, up to 90 questions, and pass rates hover in the 70–85% range for prepared candidates. You can cram it if you have to. Not ideal, but possible.
CISSP is 12–24 weeks and you can't cram it. The exam is up to four hours, up to 150 adaptive questions across eight domains, and the harder part isn't the content — it's the mindset shift. You can know all the material and still fail if you haven't trained yourself out of engineering-first thinking. Most candidates need 3–6 months of structured prep, and the people who pass on the first attempt have usually done hundreds of practice questions with detailed explanation review.
Salary: The Gap Is Real
Both certs move salary. The move from Security+ to CISSP moves it a lot.
Security+ holders typically land between $70K and $90K for entry-level analyst roles, climbing into the $85K–$115K range with a few years of experience. That's solid money for someone breaking in.
CISSP holders are in a different bracket. Mid-career sits around $120K–$150K. Senior technical and management roles pull $150K–$200K+. CISO-track roles clear $200K–$300K+. That's roughly a 60–80% lift at equivalent experience levels.
I want to be honest about what's driving that, though. The credential isn't doing all the work — most of the lift comes from the experience you had to accumulate to qualify for CISSP in the first place. If you could magically grant Security+ holders five years of senior experience without the cert, most of the salary gap would still appear. The cert is what unlocks the door; the experience is what justifies the number on the other side.
When You're Actually Ready to Move Up
You're in the zone for CISSP when most of these are true:
- You have four or more years of qualifying security experience (you'll hit five by the time you sit, pass, and get endorsed)
- You've worked in at least two of the eight CISSP domains, not just one deep specialty
- You've been in conversations about risk, policy, or incident response — even if you weren't leading them
- The jobs you're targeting list CISSP as required or preferred
And you're probably not ready if:
- You have under three years in security (no amount of study will fix this — time is the gate)
- You're still in a pure execution role with no exposure to decisions or tradeoffs
- You've spent your career deep in one domain and haven't touched the others
- You can pass Security+ practice tests but have never made a security recommendation to a manager
One more pattern I've seen repeatedly: candidates who pass CISSP too early often plateau. They earn the cert, don't get the role bump they expected, and lose motivation to build the experience that would have made the cert actually pay off. Better to wait a year, get one more role under your belt, and sit for CISSP when passing it actually corresponds to being ready for senior work.
What the Progression Usually Looks Like
For most people, Security+ to CISSP is a five-to-eight-year journey with some intermediate steps along the way.
You take Security+ early — often while you're in school or in your first IT role. It gets you into Tier 1 SOC, junior analyst work, or a security-adjacent position. From there, you spend two to four years building actual experience: hands-on security work, exposure to multiple domains, maybe a rotation through incident response or risk. Somewhere in there, most people pick up an intermediate cert — SSCP if you want the ISC2 brand early, CySA+ if you're SOC-focused, something cloud-specific if that's your lane.
Then, somewhere around year four or five, CISSP starts making sense. You've got the experience, you've got the scope, and you've probably noticed that the next job you want lists CISSP as required. That's the right time to sit for it. The full ISC2 path has more detail on how the pieces fit together.
After CISSP, specialization kicks in — CCSP if you're in cloud, CISM if you're heading management, CISA if you're going audit. But that's a problem for future-you.
Should You Just Skip Security+?
This comes up a lot, usually from candidates who already have a few years of experience and don't want to spend time on an "entry-level" cert.
Skip Security+ if you already have four-plus years of security experience, your employer doesn't care about it, and CISSP is clearly the target. There's no value in pausing to earn a credential that's going to be eclipsed by your CISSP anyway.
Don't skip it if you need a credential now — for a job application, a clearance process, or a current employer who wants to see progression. Security+ is cheap ($404), fast (4–8 weeks), and opens doors that are closed to people with zero certs. If CISSP is still two or three years away, Security+ is almost always worth it in the interim.
(The middle-ground answer: if you're deciding between Security+ and SSCP as your first cert, that's a different post. Short version: Security+ is more widely recognized outside security-specific roles; SSCP carries more weight inside the ISC2 ecosystem.)
The Honest Take
If you're still early in your career, take Security+. It's the fastest way to a first security job, and it counts toward the one-year CISSP waiver when you eventually sit for that exam.
If you've been in security for a few years and are Security+-certified already, the question isn't whether to pursue CISSP — it's whether you're ready yet. Passing CISSP a year too early costs you money (exam fees, study time) and often doesn't unlock the roles you hoped it would. Waiting a year to build experience, adding an intermediate cert, and sitting for CISSP as a qualifying candidate almost always pays off more than rushing it.
The cheapest way to find out where you actually stand is a diagnostic exam. Thirty minutes, a domain-by-domain breakdown, and you'll know whether CISSP is a few months away or a few years. Try the free CISSP diagnostic — no signup — and if you're scoring 40%+ across domains with four years of qualifying experience, you're closer than you think. If you're below that, the honest answer is usually more experience, not more studying.
