Empower secure, external collaboration with Slack Connect

Help your team work with external organizations in Slack, while keeping your company’s data and information secure

Keep up with the pace of digital transformation by giving employees a secure, more productive way to work with external customers, vendors and partners.

Slack Connect is a secure communications environment that extends the benefits of Slack to everyone you work with, both inside and outside your organization.

All of Slack’s enterprise-grade security features and compliance standards apply to Slack Connect. Plus, we’ve built in additional features that help you have confidence that your data stays safe when working with external organizations. We also just finished collaborating with Metrigy on a new report showcasing how to enable secure external collaboration.
