Custodia Cyber

Custodia Cyber helps small and mid-sized organisations secure Microsoft 365 and reduce real-world breach risk. We specialise in fast security health checks, practical remediation, and ongoing support that improves identity security, email protection, and collaboration controls across Exchange, Entra ID, Teams, SharePoint, and OneDrive. Clients choose us when they need clear priorities, quick wins, and measurable improvements, not generic reports. Services include fixed-scope security assessments, hardening sprints, and managed support packages delivered remotely, with optional on-site support in London.
