How does CiraSync handle and protect PII data?

CiraSync is hosted in Azure. Azure has more cloud security certifications than any other cloud provider in the world. Thus, the physical security of CiraSync servers are quite secure. Only three VMs are accessible via Public IP addresses. All ports are locked down to inbound internet traffic with the exception of the dashboard which allows port 443. Inter-server communication is via LAN connections on private IP addresses. Backups stay in the Azure cloud. Logs and any caching used for performance purposes are purged after 30 days.
