Summary

This customer testimonial features Nirav, Manager of IT Operations at Maddocks, an Australian legal firm handling confidential data for corporate, commercial, and government sectors. The firm successfully deployed Microsoft Copilot to 200 employees with plans to expand organization-wide by September, using Varonis to address data security challenges. Before the Copilot rollout, Varonis enabled Maddocks to identify and remediate overshared data across the organization, discovering numerous links and files shared without proper access controls. The platform's automated alert triage freed security teams from manual review processes, while real-time monitoring capabilities provided visibility into Copilot usage patterns, including prompt activity and file references. Varonis's managed detection and response service particularly impressed the IT team with its proactive approach to handling medium and high-severity alerts, giving leadership confidence to proceed with the AI deployment while maintaining their responsibility as guardians of sensitive client information.
