Cybersecurity software provider CyberFOX has acquired Optimize365. The acquisition adds continuous Microsoft 365 tenant monitoring and hardening to a portfolio that already covers privileged access management (PAM), password management, AI-powered DNS filtering, and Zero Trust Network Access (ZTNA).
IT teams across industries are responsible for securing a rapidly expanding number of different platforms and technology stacks with limited budgets and finite resources, explained CyberFOX executives. Microsoft 365 environments add another layer of complexity, with configurations, permissions, and security settings that can change rapidly over time and create risk when they aren’t carefully managed. The acquisition of Optimize365 expands the ability of CyberFOX to help IT teams identify and address these risks across both endpoint and cloud environments.
“IT teams are facing an increasingly complex access attack surface, from endpoints and identities to Microsoft 365 and beyond,” said David Bellini, CEO of CyberFOX. “Our goal is to give them a comprehensive suite of security platforms that protects the full access attack surface, without adding more complexity.”
Optimize365 will continue to operate under the Optimize365 brand within the CyberFOX portfolio in the near term. Existing Optimize365 partners and customers will see no disruption to service, support, or contracts, said the company. CyberFOX plans to integrate Optimize365 into its partner program and product roadmap over the coming quarters.
The acquisition follows the company’s nine-figure growth investment led by Level Equity and Radian Capital in February 2026, and its acquisition of SASE provider Timus Networks in June 2026.
