Things a company would want with their internal communications software

Most companies end up asking for the same core things from internal communications software, whether it's chat, email replacement or a company-wide hub. The first is security and control: single sign-on, two-factor login, role-based permissions, audit logs, and the option to keep data in a chosen region or under the company's own retention rules. The second is reach and reliability: it has to work on desktop and phone, handle people who are offline or on shift work, and keep messages in order when a connection drops. Third, it should fit into existing tools, with calendar, file storage, HR and ticketing integrations, plus an API or webhooks so systems like build servers can post updates without anyone copying them by hand. Fourth, people want search that actually finds old decisions, with threads that stay organized by topic rather than vanishing into a long scroll. Fifth are admin basics that are easy to overlook until they're needed: deleting an account cleanly when someone leaves, exporting data, guest access for contractors, and clear notification settings so people aren't pinged all day. Finally, many teams care about how the software feels: quick to load, simple to start using, and not so noisy that important messages get buried. Which of these matters most usually depends on company size and how regulated the industry is, so a small team and a bank will weigh them very differently. What has your team been using, and what frustrates you about it?
