eFax Corporate Cloud Fax Solution

Fax technology has progressed from dedicated, standalone machines to cloud-based integrated services. Today, progressive companies are moving their fax infrastructure to the cloud. By eliminating concerns about system reliability, scalability, and hardware and software maintenance, these companies are able to free internal resources to focus on other business-critical systems and processes.

eFax Corporate is a robust cloud fax platform used by thousands of customers every day to securely transmit important business documents. eFax Corporate is offered as a fully hosted online service, powered by a network of secure datacenters and colocations distributed across North America, Europe and Asia.

Our inbound faxing services operate across a highly secure network of telco-grade, Tier III and Tier IV colocations, equipped with environmental controls, infrastructure support, power management and protective equipment. Business continuity for back-end systems is provided via a geographically redundant Disaster Recovery datacenter facility. The core front-end services, Inbound and Send, utilize distinct architectural approaches designed to maximize service availability. Transmission security and system redundancy are achieved through Border Gateway Protocol (BGP), which include multiple peers and Virtual Private Network (VPN) connections between each colocation and our primary datacenter, where core backend systems reside.


Go Green!

Our secure-faxing technology is 100% paperless and requires no additional software or dedicated IT resources.
