Because of this focus on teams, using Slack for multiple jobs, teams, or projects is more organized than it would be with other tools because users such as freelancers can simply sign into another workspace. Workspaces are further broken into channels, and users can send direct messages to other people. The basis of this communication happens in workspaces, to which administrators must invite team members, reducing the risk of spoofed emails and phishing attacks. Slack can be used from practically any device in the browser, too. iOS, Android, Windows, macOS, and Linux users can all install Slack, although the Linux version is still in beta. Corporations, contractors, freelancers, and even some individual users all rely on Slack to send messages and share documents with individual users and groups across a variety of operating systems and devices. Since 2013, Slack has been at the forefront of professional communication.
