Case Study: SIG Plc Secures Immutable M365 Backup with Keepit

Keepit Provides SIG PLC with the Ultimate Insurance Policy

SIG PLC, a leading European supplier of specialist insulation and sustainable building products, needed a more reliable way to protect its Microsoft 365 data. Concerned that Microsoft only backs up live data and that admin errors or ransomware could leave it without recoverable copies, SIG turned to Keepit for third-party cloud backup.

Keepit delivered immutable, undeletable backup for M365 with role-based access control across six regions, giving each local IT team autonomy while protecting more than 7,000 users. The solution simplified administration, supported secure restores, and preserved departed-user data without extra licensing costs, helping SIG improve resilience and reduce risk.
