About Tamas
A hands-on Senior Cybersecurity Expert with 15+ years of experience in Threat Detection, Vulnerability Management, Security Operations (SOC, SIEM, SOAR), Network and Cloud Security. So far, I have helped close to 100 organisations shift to threat-informed cybersecurity practices delivering 10s of thousands of controls and detections worldwide. I am a quick learner, I process new information at an exceptional rate, and I use these skills to solve complex security challenges bridging the gap between operational, technical and business requirements, focusing on delivering measurable improvements in risk posture and efficiency. I enjoy working in a team, mentoring and leading team members, and I am also effective working solo on specific initiatives.
