Who Is a Network Security Engineer?
A Network Security Engineer is responsible for designing, implementing, and managing secure computer networks to protect an organization’s data and infrastructure from cyber threats. These professionals develop security policies, maintain firewalls, monitor network traffic for suspicious activity, and respond to incidents to ensure the network remains secure.
Unlike broader cybersecurity roles, network security engineers focus specifically on protecting an organization’s network—both on-premises and cloud-based systems—from unauthorized access, malware, and other threats.
How Much Does a Network Security Engineer Earn?
The salary of a Network Security Engineer varies based on location, experience, and industry. According to Glassdoor, in the U.S., the average annual salary ranges from $118,000 to $188,000, with senior roles earning upwards of $200,000.
In Nigeria, Network Security Engineers can earn between NGN 1.8 million to NGN 7.3 million per year, depending on the size of the organization and the engineer's level of expertise.
These figures highlight the lucrative nature of the profession and the growing demand for network security expertise across industries.
