Polish cybertech startup 1Security raises funding to strengthen microsoft 365 protection

Łódź-based 1Security, which develops a platform for managing Microsoft 365 permissions and protecting sensitive data, has secured funding from Digital Ocean Ventures, with the deal amount undisclosed.

  • Founded in 2023 by Adam Żaczek and Mateusz Olek, 1Security develops a SaaS platform that enhances Microsoft 365 security by transforming permission management from a guessing game into a controlled, transparent process. 
  • The platform maps permissions across resources, identifies sensitive data like credit card numbers, and ensures safe collaboration and AI usage with real-time rules and alerts.
  • It simplifies permission management for any entity at any scale, provides comprehensive visibility into AI and user-exposed sensitive data, and safeguards information with automated security measures. 
  • By consolidating security across apps and tools, 1Security helps organizations gain insights, take control of access rights, streamline processes with automation, and innovate with confidence.

Details of the deal

  • Krakow-based Digital Ocean Ventures, a VC firm specializing in early-stage fintech and AI-driven digital transformation startups, led the recent investment in 1Security. The firm primarily invests in Polish B2B and B2B2C companies but occasionally backs foreign startups with a focus on the CEE region.
  • 1Security will use the funding to enhance its AI-driven Microsoft 365 security platform, focusing on real-time permission mapping, automated access correction, and sensitive data detection.
