# Security

Overview of GridGain security features, including encrypted communications, authentication, authorization, and auditing.

GridGain's security features allow you to perform security activities, such as encrypting communications, configuring authentication and authorization methods, and performing audits. For example, you can secure the communications between cluster nodes by using SSL/TLS encryption. What is more, GridGain provides a convenient and flexible way for managing user roles and permissions. For example, Control Center allows to share its features between team members using the [Teams](/docs/tools/enterprise/control-center/profile/teams.md) functionality.
