Private channels are restricted and no one else can see or join a private channel.Ī really useful feature of Slack is the file sharing capability. If you have sensitive information to discuss, users can create private channels and invite a only few team members. The great thing about using channels is they can be utilized by everyone all users have a transparent view of all its aspects. Slack organizes team conversations into open channels.

The paid versions start at €6.25 per month.Slack is an online, social messaging platform that is designed for teams of all sizes, so they can collaborate on projects more effectively. The free version only includes basic features such as two-person calls, 10 app integrations, and 5 GB of storage.

Slack is available in both free and paid versions, depending on a team's needs. As always, we recommend avoiding sharing personal information and sensible customer data over the app. The company reassures that all data (at rest and in transit) is encrypted and that they use tools like Slack Enterprise Key Management (Slack EKM), audit logs, two-factor authentication, and integrations with top data loss prevention (DLP) providers.


Slack has a history of data breaches that occured in 2015. Another great thing about Slack it that if you are not sure how to use a specific functionality, there are official tutorials you can follow. All content shared within a conversation (such as files, keywords, and individual users) is completely searchable, making it easier than ever to keep track of how a conversation progresses. Users are invited to join conversations through a specific URL or via invitation sent by a team administrator.
