CISSP (Certified Information Systems Security Professional) and GSEC (GIAC Security Essentials) are two popular certifications in the field of information security. Both certifications are widely recognised and highly regarded by employers and offer valuable skills and knowledge for professionals in the industry.

However, there are several key differences between the two certifications, which can impact a professional’s career and training in the security field. This article aims to provide an analysis of CISSP vs GSEC, outlining the differences, difficulty levels, benefits, and their impact on security roles and training.

Overview of CISSP Certification

The CISSP (Certified Information Systems Security Professional) is a globally recognised cybersecurity certification that validates your information and experience in designing, implementing, and managing an organisation’s security posture. It’s widely considered the gold standard in the field, and earning it can significantly boost your career prospects.

What it covers

The CISSP Common Body of Knowledge (CBK) includes eight domains of information security:

  1. Security and Risk Management: This domain covers risk identification, assessment, mitigation, and reporting.
  2. Asset Security: This domain covers the protection of information assets, including data, devices, and applications.
  3. Security Architecture and Engineering: This domain covers designing and implementing secure systems and networks.
  4. Communication and Network Security: This domain covers network devices, protocols, and communications security.
  5. Identity and Access Management (IAM): This domain encompasses the control of access to systems and data.
  6. Security Assessment and Testing: This domain covers identifying and evaluating vulnerabilities in systems and networks.
  7. Security Operations: This domain covers the day-to-day operations of a security program.
  8. Software Development Security: This domain covers the secure development of software applications.

Who should get It?

The CISSP is ideal for skilful security professionals who want to validate their knowledge and skills. It’s also a good option for IT professionals who want to move into a security role.


To earn the CISSP, you must have at least five years of cumulative proven work experience in two or more of the eight CISSP domains. You must also pass the CISSP exam, which is a 125-question, multiple-choice exam that is administered by ISC2.

An Overview of GSEC Certification


The GIAC Security Essentials (GSEC) certification is a well-respected credential in the cybersecurity field, validating a practitioner’s comprehensive understanding of information security beyond basic terminology and concepts. Earning this certification demonstrates your ability to identify and mitigate security risks, making you a valuable asset in today’s digital landscape.
