# Overview ## Introduction Uccello provides an advanced security management system. It is possible to partition data with **domains**, give access rights to modules with **roles** and **profiles**, and share data between users with **groups**. As Uccello has been designed to meet the needs of both small and large companies, it is necessary to have a clear understanding of how it manages security. Some aspects may seem cumbersome, but we will explain to you what the advantages are and how you can configure Uccello to meet your needs in a very simple way. ## Security levels * [Domain](/doc/security/domain.md) * [Profile](/doc/security/profile.md) * [Role](/doc/security/role.md) * [Group](/doc/security/group.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
