An Introduction

Hi there, thanks for visiting.

My name is Kostas, aka SPRTN or Dio. I’m a Staff Sergeant in the USAF with a passion for cybersecurity, a husband to an incredible woman, and a dad to two energetic Pomeranians.

In my free time you can catch me spending time with family, mentoring folks, working on cybersecurity projects, watching soccer, drawing, and always seeking to learn something new.

This site will be primarily dedicated to cyber, so let’s make some cyber for the cyber god.
