Apostolos Traganis
Senior Manager, CSIRT & SOC @ NVISO Security
About
Cybersecurity Manager with deep hands-on experience across Security Operations, Vulnerability Management, and threat defense programs. I lead teams and services that protect complex environments, combining technical depth with clear operational direction. My background spans MSSP delivery, enterprise defense tooling, and risk-based security strategies that cut through noise and drive measurable impact. My goal is straightforward: deliver consistent, high-quality cybersecurity services that clients can trust, while continuously improving workflows, communication, and overall service maturity within the MSSP environment. If you’re focused on managed security operations, service evolution, or improving the client experience, I’m always open to connecting.
