MS Teams vs. Slack

Every team needs an efficient way to communicate, so what’s it going to be? Microsoft Teams or Slack?


Teams and Slack have tons of bot and app integrations to improve the user experience. For app count, Slack knocks it out of the park with over 1,500 third-party apps for users to choose from. Microsoft Teams has only been around for about 2 years compared to Slack which started in 2009.

On both platforms, users can find helper bots such as Slackbot for Slack and Who bot for Teams that can help answer their questions. For Teams, the Who bot is powered by Microsoft Graph and can help users find company information based on names or topics.


Slack and Microsoft Teams both include online audio and video sharing. But Teams was built with Microsoft’s years of experience catering to businesses large and small in collaboration with communication applications, so it’s only natural that Teams goes above and beyond with its meeting capabilities. Slack provides one-on-one calling in its free version which upgrades to 15 participants with screen sharing capability when using a paid plan. With Teams, on the other hand, even with the free version you can host meetings with up to 250 people. When you upgrade to the paid plan you can use Teams live events to host large meetings, webinars, and company-wide events with up to 10,000 attendees inside or outside your business.


One of the areas that Microsoft Teams truly shines through is in its administration controls and data security. Microsoft Teams and Slack offer data encryption and compliance certification such as ISO/IEC 27001 as well as two-factor authentication. However, Microsoft shows us how they prioritize data security with their four tiers of compliance frameworks. Microsoft Teams also provides admin controls that are more extensive than any other platform.


As a Microsoft product, the integration between the Microsoft Teams platform and Office 365 is seamless. You don’t have to leave the app to work on Word documents, PowerPoint slides, or OneNotes, and you don’t need to upload and download your video and document files to access them. When it comes to Microsoft Teams, the emphasis lies on the needs of enterprise collaboration. This means increased security and compliance measures and seamless integration with workspace applications.

On the other hand, people love using Slack. Slack is a new and fun way to collaborate in the workplace via its many integrations and features. Slack’s biggest downside, though, is that it doesn’t inherently integrate with any capabilities outside of file storage and chat. Consequently, companies need to pay extra for other tools if they want to edit or organise collaboration content or have email services.

Lately we’ve seen more companies migrate from Slack to Teams, especially in light of Google’s announcement of its development of an enterprise communications app. As of now, though, Slack and Microsoft Teams are the leading chat collaboration platforms and their likeness is necessary for an efficient, modern workplace.
