3CX

3CX is a software company that develops and markets IP‑based private branch exchange (PBX) solutions and related unified communications tools. Its core offering is a software‑only PBX that can be deployed on premises, in the cloud, or as a hybrid system, enabling businesses to replace traditional telephone hardware with virtual call management. The platform includes features such as VoIP calling, video conferencing, web meetings, live chat, and contact centre capabilities, and it is designed to work with standard SIP phones, softphones, and mobile devices. 3CX serves a broad market ranging from small and medium‑sized enterprises to larger organisations that seek a flexible, cost‑effective alternative to legacy telephony systems.

The company’s distinguishing attributes lie in its focus on delivering a fully software‑driven communications stack that eliminates the need for proprietary hardware appliances. This approach allows rapid scaling, simplified updates, and integration with a variety of third‑party applications through APIs and standard protocols. 3CX also emphasizes cross‑platform client support, providing native desktop applications for Windows and macOS as well as mobile apps for iOS and Android, which enables users to access the PBX features from virtually any device. The 2023 supply chain incident, in which trojanized versions of its Windows and macOS desktop clients were distributed after attackers compromised a partner’s trading software and stole employee credentials, highlighted the importance of secure build environments and code‑signing practices for software vendors.

Information regarding 3CX’s ownership structure, parent‑subsidiary relationships, or precise employee headcount is not explicitly provided in the supplied context, so those details are omitted here to avoid speculation. The organisation’s headquarters is located in Cyprus, which serves as the central point for its global operations and product development efforts.
