Based on Microsoft Azure SLA, we provide secure servers in our hosting facility with access through a managed firewall/VPN as the data resides on at least three different servers in two different physical locations. With a 99.99%? System Availability target, we ensure a high availability architecture. With a broad set of international certifications and industry-specific compliance standards, Azure Cloud strictly adheres to global compliance standards. Certifications include ISO 27001, FedRAMP, SAS70, SOC 1, and SOC 2. To further ensure data security, all data and log files are backed up on a regular basis with tapes stored off-site.
