1. Product Description

OX Cloud is a managed and hosted delivery platform that combines OX App Suite with an IMAP backend. The OX Cloud platform will be operated by Company under a defined service level agreement and contains the required software, infrastructure components, and services to operate the solution (in the following referred to as the “Service”).

The main component of the Service is OX App Suite, a modular, web-based communication and collaboration platform which delivers cloud‑based services including secure email, personal and team organization, cloud storage, and online office features.

OX Cloud comes with a Basic Package (defined under Section 2 below) and the two separately priced add-ons Productivity (defined under Section 3.1 below) and Advanced Security (defined under Section 3.2 below).

OX Cloud offers four basic modules that provide personal information manager (PIM) functionalities through OX Mail, OX Address Book, OX Calendar and OX Tasks.

Moreover, an integrated dashboard called OX Portal lets users configure specific functionalities and views in order to have important information in one place.

Additionally, the two add-ons, which are available on request, are Productivity and Advanced Security. The Productivity add-on consists of OX Drive cloud storage, the modules OX Text, OX Spreadsheet and OX Presentation that provide word processing, presentation and spreadsheet capabilities and the Email Undelete Feature.

The Advanced Security add-on consists of OX Guard that provides users with a flexible email and file encryption solution, Safe Unsubscribe for an efficient unsubscribing of any marketing emails and Time-of-Click anti-phishing for the additional analyzation of URLs at the time of click to identify phishing.

Subject to availability, Customer may obtain an exclusive subdomain under *.appsuite.cloud.

8. Platform Delivery Measures

The Service will be operated and managed following ITIL v3 best practices. Company updates the Service to new product versions following the product roadmap.

As technology evolves, Company reserves the right to adjust the Service according to new trends in the market or newer technology available.

8.1 Environments

Company maintains one production environment and one staging environment. The staging environment is a smaller replica of a production environment for testing purposes which receives newer software versions before they are being rolled out to the production environment. It may be used by the Customer to test and ensure interoperability with other systems. The staging environment is only for internal use and not subject to any SLA. The Customer may not use the staging environment for production use.

8.2 Monitoring

All components of the Service are monitored using an internal toolchain and are also monitored externally from the internet (details are defined in the SLA). In case of failure, the monitoring system triggers alerts that inform Company personnel and provides statistical data for further analysis.
