About this site

Hey there! I’m Nicholas Pecka. I work in cybersecurity — building defenses, tuning detection systems, and helping organizations make sense of threats before they become incidents.

Most of my career has been spent in areas like SIEM engineering, vulnerability management, and cloud security operations. Outside of work, I’m also a PhD researcher focused on improving how we do threat modeling. The current process is overly manual, and I’m exploring ways to automate and evolve it — though I’ll save the deeper details for after publication.

PeckaCyber is my corner of the internet to write about what I’m learning, building, and thinking through. Expect posts on security operations, automation, home lab experiments, and observations from working in the industry.

I’m not here to sell fear or pretend there’s one perfect tool. I’m here to talk through what actually works, what doesn’t, and where we go from here.

If that sounds like your kind of thing, I hope you’ll stick around!
