Secure deployment options that keep your data in your hands

From government agencies and intelligence organizations to financial services and healthcare companies, teams in high-security and regulated industries trust Mattermost for secure collaboration.

While Notion is a SaaS service that forces you into a public cloud, Mattermost lets you choose between on-prem and private cloud deployment options that meet your unique security and compliance needs and enable you to retain full control and sovereignty over your data. Deploy in air-gapped and other high-security environments, use EMM for secure mobile comms, and define granular controls for enterprise data archiving to keep data properly secure and accessible.
