WhatsApp at a glance
WhatsApp is a widely used messaging service that provides text, voice and video communication through mobile apps as well as desktop and web clients. In enterprise environments administrators typically encounter it via the desktop application on managed endpoints or through WhatsApp Business and its associated business API. As proprietary software, it is delivered through the respective app stores, the built-in updater of the desktop app, or managed software deployment.
Updates are shipped by the vendor in short, continuous cycles and are usually applied automatically. For sysadmins the key concern is tracking supported operating system and client versions, since older platforms are regularly dropped from support and clients then stop receiving updates.
When updating, pay attention to changed system requirements, the retirement of older client variants, and compatibility between mobile and desktop pairing. In regulated environments, data protection and compliance requirements should also be taken into account.
