Top Certifications for Network Security Administrators in 2021


From cybersecurity to IT security; the demand for security professionals is at its peak like never before. Here are some certifications that will help you polish your skills.

The majority of businesses utilize multiple computer networks in their operations. These businesses rely on these networks functioning correctly and smoothly. The network administrator’s main job is to ensure this.

You may have heard the term “network administrator” being used interchangeably with “systems administrator.” In smaller companies, both roles can be performed by the same person. But these positions take on significantly different responsibilities in larger companies. 

Systems administrators focus primarily on individual computers and devices. Network administrators focus on the interconnection of such computers in the company. However, in this article, we won’t distinguish between the two as, most of the time, network administrators and system administrators have coinciding responsibilities.

More specifically, network administrators perform the following tasks:

  1. Set up and configure the company’s local area networks (LAN) and wide-area networks (WAN).
  2. Manage the hardware and software necessary for the company’s needs.
  3. Manage the maintenance and replacement of all hardware and software.
  4. Secure the systems and network of the company.
  5. Troubleshoot issues as and when they come up.
  6. Improve the overall performance of each machine and the network as a whole.
  7. Train the company’s staff on the best practices for securely utilizing the machines and accessing the network.


Network administrators are highly in demand. Those already employed can expect more lucrative career opportunities and pay bumps. Therefore, it’s important to know how to succeed in such roles so you can make the most of them.

The following list details some of the most recommended courses and certifications.
