Your service, your brand

OX App Suite is built on open standards and APIs. This means service providers can customize the platform to promote their own brand. But OX App Suite supports more than just individual brands. It is highly configurable, allowing you and dedicated Open-Xchange teams to customize design elements and architecture, and ensure a smooth migration from existing deployments.
