About Me
I am Dennis Kontic, a cybersecurity graduate and blue team practitioner focused on SOC analysis, digital forensics, incident response, threat hunting, malware analysis, threat intelligence, and detection engineering.
I graduated from Lindenwood University with a Bachelor of Science in Cybersecurity and a Minor in Business Administration, earning a 3.94 GPA. My background includes IT support, public sector IT, information security, detection engineering, and cybersecurity education through DonkeySec.
I use this site as my main professional profile. My deeper technical work is hosted separately in my cybersecurity lab portfolio, where I document blue team projects, lab investigations, certification projects, and sanitized professional work.

Cybersecurity Lab Portfolio
Dennis Kontic Cybersecurity Lab Portfolio
My full technical project portfolio is hosted separately. It includes blue team projects, lab investigations, certification projects, defensive security writeups, and sanitized professional work.
The portfolio shows how I investigate alerts, analyze evidence, reconstruct attacker behavior, map activity to MITRE ATT&CK, and recommend defensive actions.
