Welcome to Flapped Ear.
Corgi father. Cybersec manager. Nerd. Come take a look at my world.
Arek Kozuch
Cybersecurity Operations Manager
Kraków, Poland
"I want to show you a bit of my world and try to make it a little better place — feel free to suggest changes, it's just personal."
I run 24/7 SOC operations and build detection capability at work. At home: a GT86 that needs more power, a Bambu Lab that never stops printing, and Mango — a corgi with one very floppy ear who judges all of it.
