Last Updated On: May 7, 2024

When it comes to prestigious certifications in the IT industry, CISSP (Certified Information Systems Security Professional) and CCNA (Cisco Certified Network Associate) stand out as two of the most sought-after credentials. Both certifications offer professionals a pathway to advance their careers and demonstrate expertise in their respective domains. However, despite their prominence, CISSP and CCNA serve distinct purposes and cater to different areas of specialization.

In this comprehensive guide, we'll delve into the key differences between these two certifications, exploring their respective scopes, exam details, career prospects, and more, empowering you to make an informed decision that aligns with your professional aspirations.

What is CISSP?

The Certified Information Systems Security Professional (CISSP) is a globally recognized certification in the field of information security, governed by the International Information System Security Certification Consortium, commonly known as ISC2. This advanced certification is designed for security practitioners, managers, and executives who want to prove their knowledge across a wide array of security practices and principles.

One of the standout features of the CISSP certification is its vendor-neutral approach. Unlike certifications focused on specific technologies or vendors, CISSP covers the broad spectrum of information security. This makes it incredibly versatile and applicable in a variety of settings and industries.

The CISSP curriculum is built around eight domains of security knowledge, from Security and Risk Management to Software Development Security, ensuring a comprehensive understanding of the entire information security landscape. This broad-based approach empowers professionals to design, engineer, and manage the overall security posture of an organization.

What Is CCNA?

The Cisco Certified Network Associate is a prominent vendor-specific certification that focuses primarily on networking technologies. Managed by Cisco Systems, a leading provider of networking solutions, the CCNA certification is designed to prepare candidates for today's associate-level job roles in IT technologies. CCNA now includes security, automation, and programmability, reflecting the breadth of skills required in modern network environments

Unlike the broader, vendor-neutral CISSP, the CCNA certification centers on Cisco’s own products and software, equipping professionals with specific skills to handle Cisco networks and systems. The certification covers a range of topics, including network fundamentals, network access, IP connectivity, IP services, security fundamentals, and automation and programmability.

By focusing deeply on Cisco's ecosystem, CCNA holders are well-prepared to install, configure, and operate LAN, WAN, and dial access services for medium-sized networks. This makes CCNA an invaluable asset for those seeking to specialize in Cisco environments, providing a solid foundation in core network engineering using Cisco technologies.

CISSP vs. CCNA: How Do They Differ

While both CISSP and CCNA are prestigious certifications within the IT industry, they cater to markedly different professional needs and areas of expertise. CISSP is primarily centered around cybersecurity, while CCNA focuses specifically on networking. This fundamental distinction underscores the unique pathways and opportunities each certification presents.

Below, we provide a detailed breakdown of how these two certifications differ:


Most IT certifications, including CISSP and CCNA, have specific prerequisites that candidates must meet to qualify for the exams. Understanding these requirements is crucial as they often include elements of work experience that vary significantly between certifications.

CISSP Eligibility

To sit for the CISSP exam, you need a robust background in security. Specifically, ISC2 requires candidates to have at least five years of cumulative, paid work experience in two or more of the eight domains of the CISSP. This can include full-time work, part-time positions, or internships.

If you hold a four-year college degree or an approved credential from the ISC2 approved list, one year of the required experience can be waived. For those who don’t yet meet these experience requirements, you can still take the CISSP exam and become an Associate of ISC2, giving you six years to gain the necessary experience.

However, do note that this exam is mainly targeted towards cybersecurity professionals who are at the later stages of their careers. So, even if you can take it without meeting the experience requirement, doing so can be very challenging given the comprehensive scope of the exam.

CCNA Eligibility

Unlike the CISSP, the CCNA doesn't have any mandatory work experience requirements. This makes it an ideal certification for those just starting their networking careers or students looking to validate their skills straight out of college or a networking program. The CCNA is tailored for entry-level network administrators, network support engineers, and those seeking to demonstrate their proficiency in configuring and troubleshooting Cisco networks.

Exam Details

Since CISSP and CCNA cater to distinct areas within the IT field, the structure and content of their exams also differ significantly. Each certification exam is designed to assess the specific knowledge and skills pertinent to its focus area.

CISSP Exam Details

The CISSP exam is administered using the Computerized Adaptive Testing (CAT) format, which tailors the difficulty of questions based on the candidate's previous responses. This format is designed to assess a candidate's competency more efficiently. The exam covers eight domains of knowledge:
