KFax

KFax is a cloud-based fax service that replaces traditional fax machines with digital transmission of documents over the internet. It allows users to send and receive faxes via a web portal, email, mobile apps, or integrated software through an API. Faxes are transmitted over FoIP (Fax over IP) using protocols such as T.38, and can be delivered as PDF or TIFF attachments. Inbound faxes can be routed to specific users, email addresses, or automated workflows.

KFax provides virtual fax numbers in multiple regions, supports mass dispatch, and offers archival storage with full-text search through optical character recognition (OCR). Security features include data encryption in transit and at rest, TLS for transmissions, AES-256 encryption, two-factor authentication, and role-based access controls. Compliance options cover HIPAA in healthcare contexts and other industry standards, depending on configuration and region.

In operation, KFax integrates with common business systems, including email platforms, cloud storage, and enterprise resource planning or customer relationship management tools. Usage is typically billed per user, per month, plus per-page or per-fax charges, with volume discounts for larger deployments.

As a concept, KFax is presented as an alternative to traditional fax solutions, emphasizing scalability, accessibility, and ease of use across devices.
