What Does a Network Security Engineer Do?


Cybersecurity is complex. The digital transformation, remote work and the ever-evolving threat landscape require different tools and different skill sets. Systems must be in place to protect endpoints, identities and a borderless network perimeter. The job role responsible for handling this complex security infrastructure is the network security engineer.


In a nutshell, the network security engineer is the person who is responsible for the design and implementation of the organization’s security system, ensuring there are no gaps or vulnerabilities for threat actors to exploit. They aren’t just responsible for protecting the infrastructure from potential cyberattacks but also for safeguarding the network’s physical security from all types of intrusion or natural disasters. This is the position that creates and enforces an organization’s security policy. A network security engineer maintains the hardware and software that act as the first line of defense during an attack.


While the titles sound similar and people sometimes use them interchangeably, network security engineers are different from network security architects. The architects are usually higher level: They analyze and test a system and decide what tools are needed. However, the engineers are the ones who put it all together and keep it running properly. In smaller companies, the network security engineer may be asked to take on the tasks of an architect, but they are generally separate roles.


How In-Demand is this Particular Role?


Because they handle the first lines of defense in a security system and are also responsible for disaster recovery, network security engineers are in high demand, even though the jobs themselves may not be found under this exact title. Every company needs someone with the training to do the basic maintenance and hardware configuration to harden the network perimeter. With remote a ..
