In cybersecurity, networking is not optional background knowledge. It is the environment everything else lives on.
Whether you are investigating suspicious traffic, troubleshooting authentication issues, reviewing firewall activity, or trying to understand how systems communicate across segmented environments, networking shows up constantly. That is why I decided to earn the CompTIA Network+.
I did not take it because I thought it was the most prestigious networking certification on the market. I took it because I wanted a stronger foundation. In cybersecurity, a solid baseline in networking pays off everywhere.
Why I took Network+
At the time, I was stepping into a role where understanding network infrastructure mattered more than ever. My employer emphasized that knowing the fundamentals would make it easier to navigate complex environments and troubleshoot issues effectively. At the same time, I was also building out my own homelab with routers, access points, switches, VLANs, and a VPN, which made the gaps in my knowledge more obvious.
That is where Network+ made sense.
It gave me a structured way to strengthen the basics and fill in the areas that were still fuzzy. It also complemented the rest of my certification path well. While Network+ is not a substitute for deeper networking experience or a more advanced certification track, it is a useful way to prove that you understand the language and core mechanics of modern networks.
What Network+ actually gives you
To me, Network+ gives you broad operational literacy.
It helps you understand how devices communicate, how traffic moves, how segmentation works, where protocols fit, and what can go wrong when something breaks. That may sound basic, but in security work, basic is often where the real issues are hiding.
A weak networking foundation makes everything harder. Logs make less sense. Security tools feel more abstract. Troubleshooting takes longer. Alerts become harder to interpret. On the other hand, when you actually understand the network, you can reason through problems much faster.
That is the real value of this certification. It is not just about passing an exam. It is about becoming more effective in every adjacent area.
How I studied
I studied full time for about a week and a half, usually around eight to ten hours a day. That pace is not necessary for everyone, but it worked for me because I wanted to stay immersed in the material until test day.
A few resources mattered most.
Professor Messer
Professor Messer’s Network+ video series was one of the most useful parts of my prep. The videos are clear, direct, and efficient. They are especially good when you need a structured pass through the full exam scope without a lot of wasted time.
Dion practice exams
Professor Dion’s practice exams on Udemy were probably the most valuable resource overall. Practice questions help you do more than check recall. They teach you how CompTIA frames questions, how distractors are used, and where your weak spots really are. That mattered a lot. Networking has enough moving parts that it is easy to feel confident until a question forces you to distinguish between two similar protocols, standards, or troubleshooting approaches.
Flashcards and repetition
For topics like port numbers, WiFi standards, cable types, and connectors, I used physical flashcards. That kind of repetition helped lock in the smaller details that are easy to mix up under exam pressure.
Organizing the material
One thing that helped more than expected was keeping my notes organized in a central system. When you are learning networking, you are constantly jumping between related ideas like VLANs, subnetting, routing, wireless standards, and protocols. Having a place to keep those concepts organized makes review a lot easier.
What made the exam challenging
The hardest part was the volume and variety of material.
Network+ is broad. You need to know protocols, ports, physical media, wireless concepts, routing basics, troubleshooting logic, and how different pieces of infrastructure fit together. None of those areas alone are impossible, but taken together they create a lot of surface area to cover.
The exam also includes performance based questions at the beginning. These are the items that feel closest to mini labs. You may need to troubleshoot a scenario, analyze a network diagram, or make configuration oriented decisions in a more interactive format. I found it more effective to move past those initially, answer the multiple choice questions first, and then return once I had settled in.
That strategy helped preserve time and kept me from getting stuck too early.
What helped the most
The biggest advantage was connecting the material to real use.
Because I was already working in cybersecurity and building out a homelab, the concepts were not floating in isolation. VLANs, VPNs, switching, and access points were things I was actively thinking about outside the exam. That made the content easier to absorb and easier to remember.
That is also why I think Network+ is especially useful for people in security. Even if you never become a network engineer, understanding how networks are built and how traffic behaves makes you better at almost every defensive task.
Advice for anyone taking Network+
If I had to give a few practical takeaways, they would be these.
First, do not underestimate the value of practice exams. They are one of the best ways to pressure test whether you actually understand the material or just recognize it.
Second, spend time getting comfortable with performance based questions. Even if you cannot replicate the exact exam environment, you should understand the style of thinking they require.
Third, do not ignore the basics just because they seem small. A lot of exam questions punish weak recall on simple things like ports, protocols, connectors, and standards. That is where flashcards and repetition really help.
Final thoughts
Network+ is not the most glamorous certification in cybersecurity, but it is one of the most useful.
It gives you a working foundation in networking that improves the way you think about systems, alerts, traffic, and troubleshooting. That foundation matters. In security, a lot of your job comes down to understanding communication, trust boundaries, and how things are supposed to behave. Networking is at the center of all of that.
For me, Network+ was worth it because it helped formalize a skill set that I knew would keep showing up throughout my career. It was less about collecting another certification and more about making sure the foundation underneath everything else was solid.
