In this interview, I sit down with a cybersecurity analyst who made a major career switch—from working as an electrician to breaking into cybersecurity. One of the key tools in that journey? Wireshark.

We chat about:

How Wireshark helped him transition into IT and cybersecurity
Whether Wireshark is still relevant in modern security roles
How packet knowledge helped him stand out in the job field
What he’d focus on if he were starting today

If you’re considering a career change into IT or cybersecurity—or you’re wondering whether learning Wireshark is still a good use of your time—this conversation will give you a realistic perspective from the real world.
