CCSI

Consensus Cloud Solutions, Inc.

A provider of cloud-based faxing and digital document services, best known for eFax, the online fax service that lets people send and receive faxes through email. The company was spun off from j2 Global (now Ziff Davis) in 2021, taking the eFax brand and related document-exchange products with it. Its name nods to the idea of reaching "consensus" on documents — getting parties to agree on a single digital version.
