What is CISSP?

Certified Information Systems Security Professional (CISSP) is an autonomous data security certification given by the International Information System Security Certification Consortium, which is also known as the (ISC)².

The CISSP title is a recognized, vendor-neutral specification certifying to an IT security expert’s technical abilities and hands-on knowledge in applying and controlling a security plan.

As of January 1, 2021, there are 147,591 (ISC)² participants having the CISSP certification globally. In June 2004, the CISSP label was approved under the ANSI ISO/IEC Standard 17024:2003. CISSP is also officially approved by the U.S. Department of Defense (DoD) in their Information Assurance Technical (IAT), Managerial (IAM), and System Architect and Engineer (IASAE) groupings for DoDD 8570 certification requirements.

CISSP is perfect for skilled security specialists, managers, and officials who are interested in establishing their expertise across an array of safety practices and principles:

  • Chief Information Security Officer
  • Chief Information Officer
  • Director of Security
  • IT Director or Manager
  • Security Systems Engineer
  • Security Analyst

How to become CISSP – Certified

Becoming a CISSP needs more than just passing the CISSP exam. Applicants have to have five years of full-time hands-on knowledge in at least two of the eight CISSP domains.

The (ISC)² recommends a four-step pathway for certification to applicants, starting with determining that the CISSP credential is the right credential for them. The (ISC)² advises CISSP certification for candidates who are skilled cybersecurity practitioners.

The next step that (ISC)² recommends is preparing and enrolling for the certification exam. Many candidates enroll in CISSP training courses to prepare for the exam.

We are providing instructor-led training on CISSP Certification in association with an official (ISC)² training partner.


The CISSP exam is six hours long and comprises of 250 MCQs and complex innovative questions examining the applicant’s knowledge and understanding of the eight CISSP domains, security, and risk management, asset security, communications and network security, security engineering, security assessment and testing, identity and access management, security operations, and software development security. The results are computed on a scaled score, with a score of 700 or more out of a 1,000-point maximum needed to qualify for the credential.

The CISSP exam is offered in English, Chinese, Korean, French, German, Brazilian Portuguese, Spanish, and Japanese.

The CISSP exam costs around $699, although accurate pricing and taxes vary based on the site of the exam. Attendance at the certification exam can be rearranged for a $50 fee and there is a $100 fee for exam cancellation.
