A mid-sized law firm accidentally exposed sensitive data belonging to multiple clients. Despite their SharePoint being secured according to Microsoft’s recommended standards by their MSP, an oversight occurred. Client folders were organized within a central customer library, and lawyers were instructed to share specific folders with clients using secure, time-limited links.
Under pressure to meet deadlines and responding to client access issues, a senior lawyer mistakenly shared the entire root customer directory instead of a single folder. Although INSIGHT detected this unauthorized sharing and issued alerts, the IT staff were on leave and had not set up backup monitoring for such critical notifications.
The client quickly realized they had access to other clients’ confidential information and confronted the lawyer, expressing serious concerns about the firm’s data security practices and threatening to withdraw their business.
In response to this breach, the firm reconfigured INSIGHT to send high-priority alerts directly to both IT personnel and the individual users responsible for risky actions. This proactive measure has significantly reduced incident detection and response times, strengthening the firm’s overall data security and client trust.
