Tomas
Hofmistr

Security Engineer & Ethical Hacker

Bridging web development and IT security. I protect systems with the same precision used to build them, from network perimeters to cloud identity and DevSecOps pipelines.

From Code to
Defense

I spent years building software and managing IT infrastructure. Now I apply that same technical depth to securing it.

My background gives me an attacker's perspective and a builder's instincts, I know how systems are constructed, so I know exactly where they break. This lets me identify vulnerabilities others miss and communicate risk clearly to both technical and business stakeholders.

Currently focused on cloud security, identity protection, and SIEM-driven threat detection in enterprise environments.
