Adam Żaczek is the Founder, CEO, and CTO of 1Security, a cybersecurity platform dedicated to bringing clarity and control to the Microsoft 365 ecosystem. Prior to 1Security, his technology ventures secured multi-stage funding from top-tier VC funds and successfully supported the growth of tens of thousands of users. The vision for 1Security was born when Adam realized a critical flaw in enterprise IT: even the most advanced organizations struggle to answer the fundamental question of who has access to their sensitive data and why. Recognizing that traditional access management models were failing at the scale of modern, decentralized cloud data, he built 1Security. Today, Adam focuses on engineering solutions that untangle permission chaos, enforce Zero Trust, and prepare enterprises for the secure adoption of AI, emphasizing deep visibility, intuitive forensics, and automated remediation.
