Ransomware Recovery: Freight Company Near Pearson (Logistics)

-
PHIPA Compliance Gap: 3-Dentist Practice, North York (Dental)
RCDSO audit prep revealed patient charts accessible from every workstation with no access logs — a likely reportable breach gone undetected for months. Outcome: RCDSO audit result: 0 findings. Compliant in 8 weeks with role-based access controls, PHI audit logging, and encrypted storage.
-
