Otsar Shem Tov - Network Architect & DevSecOps Architect & Security Consultant

About

I am a highly experienced and certified IT Security Consultant with over 15 years of experience in Cybersecurity & Compliance for global organizations. Throughout my career, I have served in leadership roles including Vice President, successfully managing teams and delivering projects on time and within budget. While I excel in leadership positions, I maintain a hands-on approach, believing that strong technical expertise is fundamental to project success.

I specialize in designing and implementing secure, scalable IT infrastructure solutions while providing strategic team leadership. My approach aligns with client objectives and governance frameworks, including Cyber Management System (CISM), ISO 27001:2013, and SOC 2. I combine technical expertise with strategic thinking to deliver comprehensive security solutions that meet both current needs and future challenges.

In recent years, I have expanded my expertise into Artificial Intelligence, helping organizations adopt AI securely and put it to work across their infrastructure and security operations.
