What is CCNA?

The CCNA certification is an entry-level credential offered by Cisco, a global leader in networking and telecommunications technology. It is designed to validate a professional’s ability to install, configure, and troubleshoot networks. The certification covers a wide range of topics including networking fundamentals, IP addressing, security, routing, and switching.

With the growing importance of networking in today’s digital world, having a solid foundation in these skills is invaluable for IT professionals in almost any sector.

Why is CCNA Still Relevant in 2025?

1. Networking Fundamentals Are the Backbone of IT Infrastructure

Every business, from small startups to large enterprises, relies on networking infrastructure. As more companies transition to digital platforms and adopt technologies like cloud computing, IoT (Internet of Things), and AI, networking remains the backbone of their IT infrastructure. The CCNA certification provides professionals with essential skills in setting up, securing, and maintaining these networks, ensuring that IT systems are functioning at optimal levels.

2. Hands-On Skills for Real-World Applications

Unlike some certifications that are purely theoretical, CCNA prepares candidates with hands-on experience. Through labs, exercises, and simulations, it allows professionals to work on configuring routers, switches, and troubleshooting real-world network issues. This practical experience is crucial for IT professionals who want to be effective in their roles and solve problems quickly in the workplace.

3. A Gateway to Advanced Cisco Certifications

The CCNA certification serves as a gateway to more advanced certifications in Cisco’s vast ecosystem, such as CCNP (Cisco Certified Network Professional) and CCIE (Cisco Certified Internetwork Expert). For IT professionals looking to specialize in more complex networking fields or pursue higher-paying roles, the CCNA acts as the foundational step. Achieving higher certifications can increase earning potential and open doors to more senior roles.

4. In-Demand Networking Skills Across Industries

Networking skills are in high demand across a wide variety of industries. From tech companies to healthcare, finance, and education, virtually every sector needs professionals who understand how to build and secure reliable networks. According to recent reports, companies are increasingly seeking individuals with solid networking expertise to manage cloud networks, cybersecurity, and data centers.

The CCNA certification allows professionals to prove their expertise in these areas and stand out in a competitive job market.

5. Cybersecurity Integration

As the world faces increasing cybersecurity threats, networking and security go hand in hand. Cisco has integrated security concepts into the latest CCNA exams, covering topics like firewalls, VPNs (Virtual Private Networks), and secure network access. This integration ensures that CCNA-certified professionals are prepared not only to build efficient networks but also to protect them from threats — a key skill in today’s cybersecurity-conscious environment.

6. Boosting Career Prospects and Earning Potential

CCNA continues to be recognized by employers as a trusted credential for networking professionals. With this certification, IT professionals gain credibility and increase their chances of landing higher-paying positions. According to various salary surveys, network administrators and network engineers with a CCNA can expect to earn competitive salaries, with the potential for significant increases as they gain more experience and further certifications.
