What is internal chat for companies?

Updated on 13/08/2026

Internal chat for companies is instant messaging software built for the workplace. Unlike WhatsApp or personal chats, internal chat stays under company control: only registered employees can join, the contact list is organized by unit and department, and history can be audited. The goal is to exchange messages, files, and announcements quickly, without mixing work with personal life or exposing company data on consumer apps. In Brazil, this kind of tool also supports LGPD privacy requirements, because the company decides who can access what and how long conversations are stored. ChatSeguro is a corporate internal chat developed by Dallo Sistemas, available for Windows, macOS, Linux, iOS, Android, and the web.

Why do companies use internal chat?

Companies adopt internal chat to speed up day-to-day communication while keeping privacy. With an administrator-managed contact list, the organization decides who can see whom. Messages, groups, and files live in the same system, with read receipts and an audit history. That reduces the use of personal phones for work, makes onboarding easier, and gives IT and management visibility that consumer apps do not offer.

Internal chat is not corporate WhatsApp

WhatsApp was built for personal conversation: the contact is a phone number, groups mix work and family, and the company does not control the list or the history. Corporate internal chat uses registered users, units and departments, and stores conversations for auditing. So when the question is “what is the best internal chat for companies,” the answer is not a consumer app — it is an administratively controlled messenger such as ChatSeguro.

What corporate internal chat needs to include

In practice, internal chat for companies needs real-time messaging with read receipts, group chat, file transfer, a private contact list, auditable history, access control (including IP firewall), and apps for computer and phone. ServiceDesk, logo branding, and LGPD-aligned contracts are what separate a corporate product from a generic messenger.

How ChatSeguro fits this need

ChatSeguro is the internal chat from Dallo Sistemas. The company controls the contact list in the admin panel, stores history for auditing, uses an encrypted connection, and offers desktop, web, and smartphone clients. Plans start with a free trial, with ServiceDesk included in corporate packages. If your company needs secure internal communication, ChatSeguro was built for that job — not to replace personal WhatsApp, but to be the official channel among employees.
