The CISSP Certification: Is It Worth It?

The Certified Information Systems Security Professional (CISSP) certification is a touchy subject. Those who’ve completed the course – and there are a few at Immersive – will tell you that it’s no mean feat. UK NARIC, the UK agency that compares international qualifications and skills, attested this in a recent study, weighing it equally to a master’s degree. But can a course that takes just hours to pass really compare to one that requires two years?

Is CISSP Equivalent to a Master's Degree?

The input necessary to achieve a master’s is arguably far greater than that required to attain the CISSP certification. Online training providers offer CISSP crash courses that prepare candidates in a week, but you couldn’t scratch the surface of a master’s in this time – coffee-fueled all-nighters or otherwise. The meager few-hundred pounds that the CISSP cert costs has also sparked debate, and those who’ve splashed thousands on a master’s are understandably peeved that their time, money, and effort are deemed no worthier than a three-hour test.

How Long Is CISSP Valid?

The CISSP-qualified among us don’t have it all their way, though, as the credential is valid for just three years. You can renew it by obtaining 120 continuing professional education (CPE) credits or retaking the exam before the certification expires, but an annual maintenance fee is still required. A master’s, on the other hand, stays with you for life – but that doesn’t make it truly evergreen. The fast-moving nature of cyber means that knowledge gained depreciates quickly, and within a decade, you are ultimately left with a tired bit of paper. The CISSP certification also requires you to have at least five years of full-time, relevant job experience before taking the exam, so those who’ve passed will tell you it’s the fruit of many years’ labor.

Regardless of workload and difficulty, the industry-wide perception is that CISSP is more useful for getting a cybersecurity job than actually doing a cybersecurity job. It focuses on assessing cybersecurity knowledge, problem-solving, decision-making, and understanding industry standards and policies, but the practical component leaves much to be desired. As cybersecurity is highly technical, this is an insurmountable pain point.

What Are the Limitations of CISSP?

Certifications can provide a theoretical footing in cybersecurity, but nothing will improve human cyber readiness like hands-on experience, which is why CISSP’s elevated status is problematic: it promotes an outdated way of validating learning. Those who want to further their cybersecurity careers may look on and think, ‘that’s great, everything I need to get a top-paying job can be bought for a few hundred pounds and ticked off in a week’, when nothing could be further from the truth. Cyber is a rapidly evolving industry, and for individuals to be of value – that is, to improve their organization’s risk posture and not just check a box to get through a recruitment process – they must upskill constantly. Threat actors don’t sit an exam and decide that’s enough to be going on with; they innovate every day, and the same must be true of the good guys.

Why Hands-On Cyber Skills Matter More Than Certification

Whether you are CISSP qualified or have a cyber-related master’s is irrelevant if you aren’t continually equipping yourself with new skills, practicing them in real-world scenarios, and evidencing the outcome. When the UK NARIC equivalency finding was published, one user on X (formerly Twitter) responded: "In light of the #CISSP news on equivalency with MSc, I've decided that my 20+ years' commercial experience now confers the official status of Grand Master."

CISSP FAQs

How Long Does It Take to Get CISSP Certified?

CISSP exam preparation typically takes one to several weeks with a focused study program. Dedicated crash courses offered by online training providers can compress preparation into as little as five to seven days. The exam itself is approximately three hours.

Is CISSP worth getting in 2025?

CISSP remains a widely recognized credential for cybersecurity professionals, particularly for managerial and governance roles. It demonstrates knowledge breadth and meets ISC2's five-year experience requirement. However, it has limited practical, hands-on assessment — making it more valuable as a career signal than a measure of operational capability.

What is the CISSP experience requirement?

Candidates must have a minimum of five years of cumulative, paid, full-time work experience in two or more of the eight domains of the CISSP Common Body of Knowledge (CBK) before sitting the exam.

How often do you need to renew CISSP?

CISSP must be renewed every three years. Renewal requires 120 Continuing Professional Education (CPE) credits and payment of an annual maintenance fee to ISC2. Alternatively, candidates can retake the exam before their certification expires.

What are the alternatives to CISSP for building cybersecurity skills?

Hands-on platforms that simulate real-world cyber environments — including cyber range exercises, crisis simulations, and role-based labs — develop practical capabilities that certification exams cannot replicate. For organizations, these approaches also produce measurable evidence of workforce capability, not just credential attainment.
