What NTT Cloud Fax is

NTT Cloud Fax is a paid, web-based service for sending and receiving faxes, including international faxing. It provides a virtual fax number and lists five users. The Cloud Fax Service - Per Line plan covers five fax senders per line, while an Additional User option adds one person to the permitted outgoing-fax user list. A pay-as-you-go outbound fax option is listed for faxes outside included destinations or plan coverage. Pricing is on request, and no plan prices are listed. The service details also list 24/7 monitoring coverage, a coordinated response model, threat hunting, and incident response. Log retention is 90 days, and coverage areas are listed as all three.
