That’s why secure messaging is key to safeguarding sensitive information that colleagues must share for success. Mattermost’s secure messaging workspace provides maximum control and flexibility for dealing with emerging threats and complying with new laws such as GDPR and the CLOUD Act.

“When we were looking for a highly secure, easy-to-deploy solution to manage communications for a robust command center, Mattermost exceeded our expectations and enabled us to replicate the functions of a well-funded operations center at a fraction of the cost.

Case study

Uber requires massive collaboration from tens of thousands of concurrent users across all devices, plus extensive workflow integration and automation. Slack couldn’t scale to a production environment of tens of thousands. Other messaging platforms and web applications weren’t secure. Mattermost provided the enterprise messaging solution that could meet Uber’s needs. Uber used Mattermost’s open source platform to create a solution called “uChat.”
