Who is Enterprise Cloud Fax for?
Businesses search for highly capable fax solutions for various reasons. Whether it’s because of size, fax volume, process criticality, compliance regulations, or specialized requirements, Retarus Cloud Fax is the preferred choice for enterprise faxing needs.

Large Enterprises
Large or highly fluctuating fax volumes, hundreds or even thousands of users, complex corporate structures, and geographically dispersed subsidiaries can quickly put traditional fax solutions under pressure. Enterprises need a solution capable of handling high volumes that is flexible enough to handle changing demand.

Critical Processes
Organizations sending or receiving critical information such as lab results, patient files, invoices or contracts cannot afford to lose any faxes in transmission. Strict compliance regulations in sectors such as healthcare, finance and legal force businesses to find a reliable, secure fax solution.

Complex Requirements
When businesses have very specific requirements for a new fax solution such as SIP Trunking, integration into legacy applications, or dedicated service managers, they require an enterprise-level cloud fax provider that can adequately fulfill these needs.
