Architected specifically for zMailCloud, delivering high performance, security, privacy and resiliency, our cloud is built between two carrier-class data centers located near Dallas, Texas, and Washington, D.C., in which Fortune 100 and U.S. Federal agencies share space with us.  Worried about network latency?  Don’t!  Our performance is so good that we support customers in more than 100 countries, even though we’re hosted and supported exclusively within the continental United States.

Resilient & Secure.  Designed to withstand and recover quickly from disasters, the secure facilities are connected directly to each other by a dedicated 1Gbps fiber optic line, and maintain multiple connections not only to the backbones of the internet (multi-homed), but also power grids. Staffed 24×7, our infrastructure is under 24-hour guard, from biometric identification for physical access, through advanced digital intrusion prevention, detection and response.

Professional & Committed.  Our support team is trained to help keep our customers’ security and privacy, and we document our commitment to both privacy and performance in our Terms of Service (ToS) and Service Level Agreement (SLA).
