CISSP — Certified Information Systems Security Professional

What is the CISSP certification?

The Certified Information Systems Security Professional, or CISSP certification, is overseen by the non-profit organization (ISC)² and validates your skills around designing, implementing and maintaining a cybersecurity program. It is the most requested certification in U.S. cybersecurity job openings. This is due to the broad range of material the CISSP covers, the on-the-job experience requirements and the CISSP endorsement requirement. This makes the CISSP an easy benchmark for hiring managers looking to confirm a certain level of cybersecurity knowledge and real-world experience in candidates.

CISSP requirements: How do I get the CISSP?

There are several CISSP requirements you must meet to earn and maintain your certification.

CISSP eligibility

To earn your CISSP, you must:

  • Pass the CISSP exam
  • Sign the (ISC)² code of ethics
  • Get endorsed by either a fellow CISSP holder or (ISC)² itself
  • Have five years of work experience in two or more of the CISSP domains. A degree or certain approved certifications can be used to satisfy one year of experience via the CISSP experience waiver.

If you do not have the required work experience upon passing your exam, you will become an Associate of (ISC)², or CISSP Associate, until you meet the experience requirements.


The CISSP Exam

The CISSP exam is updated every three years, and the most recent update went into effect in May 2021. The goal of the exam is to test your knowledge in effectively designing, engineering and managing the overall security posture of an organization. Read an overview of the CISSP exam to learn more.

What is the CISSP exam outline and structure?

In 2017, the English version of the CISSP exam moved to a Computer Adaptive Test (CAT) format, which changes the difficulty of the questions based on your previous answers. This allowed (ISC)² to cut the test from six hours and 250 questions to a much more manageable three hours and 125–175 questions. In addition to multiple-choice questions, the CISSP exam may include some questions in the drag-and-drop or hotspot format.

Non-English versions of the exam are available in the six-hour linear exam format. However, both versions of the exam feature the same content, which is aligned to the CISSP CBK (Common Body of Knowledge).

How hard is the CISSP exam?

The CISSP exam has been described as a mile wide and an inch deep, and you need to score “above proficiency” in each domain to pass. That breadth of knowledge may make it difficult for those with more specialized knowledge and experience. Also, the adaptive nature of the CAT exam can make the exam feel more difficult, as each question is designed to be challenging.

CISSP pass rates vary depending on an individual’s experience, study habits and test-taking strategies. Those who take an Infosec CISSP Boot Camp average a 93% pass rate.

How do you take the CISSP exam?

Pearson VUE is the global administrator of all (ISC)² exams, and all CISSP exams must be taken in person at a Pearson Vue test center. To take your CISSP exam, create a Pearson VUE account, find a test location near you and schedule your exam. If you have a CISSP voucher or exam payment included with your CISSP training, you can redeem it during this process.

How much does the CISSP exam cost?

The CISSP exam costs $749 in all regions except the U.K. (585 pounds) and Europe (665 euros). Person VUE charges $50 (35 pounds and 40 euros) to reschedule your exam and $100 (70 pounds and 80 euros) to cancel your exam. If you do not take your exam within one year of your initial exam scheduled date, you will not be refunded for canceling your exam.

How long does the CISSP certification last?

CISSP renewal is required or your CISSP certification will expire. This involves two steps:

  • CISSP annual maintenance fee (AMF): A $125 fee must be paid upon certification and every year after (by the anniversary date of getting certified). If you hold more than one (ISC)² certification, only one fee is required to maintain all your (ISC)² certs.
  • CISSP CPEs: (ISC)² requires 120 continuing professional education (CPE) credits over a three-year period, with a recommended goal of 40 CPEs each year. Of those, at least 30 must be from Group A activities, which are directly related to the CISSP domains, and up to 10 can be from Group B activities, which are general professional development activities.

Paid CISSP training and exam prep

How long you need to study for the CISSP exam depends on your existing knowledge and experience — and your method of training.

Live CISSP boot camps

For those looking to get certified quickly, a live online or in-person CISSP boot camp may be the best option. For example, the Infosec CISSP Boot Camp allows you to earn your CISSP in one week — with six days of training plus a day to schedule and take your CISSP exam. Other boot camp providers include Training Camp, Learning Tree and Global Knowledge.

The benefits of a live boot camp include:

  • Live interaction with your instructor and peers: This can be especially useful for more advanced certifications where fellow students have years of real-world experience and situations to share.
  • Complete training package: Most boot camps come with everything you need to succeed — from live instruction to exam vouchers to books and practice exams. Infosec’s boot camp also comes with extended access to CISSP concentration training (ISSAP, ISSEP and ISSMP) and other hands-on labs to keep your skills sharp after you get certified.
  • Improved pass rates: Boot camp providers like Infosec stand by their training with an Exam Pass Guarantee. That means if you fail your exam on your first attempt, you’ll get a second attempt to pass — for free.

Self-paced CISSP training

For those with more time — and self-discipline — a number of training providers offer paid CISSP courses you can complete at your own pace, including companies like Infosec, Cybrary, Udemy and (ISC)².

The benefits of on-demand CISSP training include:

  • Train at your own pace: Train when it’s convenient for you — whether that’s 30 minutes over your lunch or a few hours on the weekend. There’s no need to set aside 40-60 hours for a week of intense, live instruction.
  • Build an individual training plan: Since you’ll be training by yourself and not with a group, target your training around the domains and objectives you need to learn the most. Consider joining a study group or connecting with peers if you’d like further insights from your peers.
  • Take the exam when you feel ready: With more time to study, you’ll have more time to get prepared without feeling like you’ll lose the benefits of the boot camp “exam cram.”
