Shadow spreadsheets: The security gap your tools can’t see

A sponsored article by Grist Labs highlights the security and governance risks of “shadow spreadsheets,” where oversharing and spreadsheet sprawl expose sensitive data, fragment sources of truth, and eliminate auditability. It argues that training, strict policies, and custom app development often fail to balance flexibility and control, and promotes Grist—a spreadsheet-like, relational, self-hostable platform with granular row/column RBAC, SSO/VPN support, audit logging, SIEM integration, and comprehensive visibility—as a means to deliver familiar spreadsheet workflows with strong access controls and a single source of truth.
