The overall goal of data residency (formerly called data locality) in Webex App is to keep user data in regional data centers that correspond with the organization's location. This offering is available for new organizations and provides the following high-level functionality:

• Your users have a single identity stored in your organization's geographic region. The identity service in your organization's geographic region handles client authentication requests.

  Your users can continue to meet with, message, and call users in other organizations across the globe without the need for separate accounts in foreign clusters. This means that Webex App does not proliferate extra personally identifiable information.

• Encryption keys for your users are created and stored in your organization's geographic region, and the key management service (KMS) in your region handles requests for the keys to encrypt and decrypt spaces, messages, and content in Webex App.

  While the keys are stored and handled in your region, note that in this phase of data locality, the encrypted user-generated content (messages, whiteboards, files and related metadata) continues to be stored in global data centers with the data of all other organizations.

• Encrypted user-generated content (messages, whiteboards, files and related metadata) is stored in the organization's geographic region. This feature is available to new Europe, Middle East, Africa, Russia (EMEAR) organizations created after February 28, 2020.

• We store data about your organization, such as verified domains, preferences, and security settings, in your geographic region.

• Partners in one region can create customer organizations in any region.

• Hybrid Data Security is now supported for organizations in the European region.

  Hybrid Data Security allows organizations to bring encryption key management and other security-related functions into their own premises data centers.

• Hybrid Calling for Webex Devices is now supported for organizations in the European region.

  Hybrid Calling for Webex Devices provides on-premises Unified CM calling capabilities to Cisco Webex Room, Desk and Webex Board devices that are registered to the cloud.

• Webex Video Mesh is now supported for organizations in the European region.

For data residency, we added a European geography (GEO) with data centers in London, Frankfurt, and Amsterdam. The existing data centers in the United States of America continue to serve North America and the "Rest of World" (RoW).

Messaging Data Residency

During provisioning, the administrator who sets up an organization sees a Country Selector drop-down menu in Control Hub. We determine the geographic region in which the organization's data resides based on the selected country. When you create a trial and select a country that maps to the European region, the organization's user-generated content is stored in the region as well as the user identities and encryption keys.

To determine which region a country maps to, you can download the following Microsoft Excel file and select the country name from the drop-down menu: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/cloudCollaboration/wbxt/datalocality/CountryCodeGEOmapping.xlsx (The file begins to download immediately when you access the link.)

Meetings Data Residency

Meetings data is stored in a data center based on the time zone that you select for a Webex Meetings site during provisioning. If you select a time zone from one of the European Union cities, then the Meetings data will reside in the data center in Frankfurt. Meetings data for other time zones outside of the European Union will reside in whichever data center is closest to the selected city.

At Cisco, we're committed to the protection and privacy of our customers’ data and personal information. The new data center in Frankfurt, Germany is part of this effort and complements existing data centers in the region, providing additional opportunities to host data in the EU. Starting July 2021, new Webex customers from Europe will be provisioned to the data center in EU. We also have a migration plan in place to provide existing customers with more flexibility, and to manage your meetings data migration from the data center in London to the one in Frankfurt through Control Hub.

The following tables describe how data is shared, processed, and stored in various scenarios. Because Webex App enables collaboration amongst users in multiple organizations, the rules for storage and processing depend in some cases on the type of collaboration, and whether you enable communication with other organizations.

In each table, the following designations are used for data residency:

Global—Data may be handled at a Cisco data center in any location.

Limited—Data resides in the organization's geographic region, but copies may be created or processed in other regions as needed.

Restricted—Data resides in the organization's geographic region.

In addition to sharing, processing, and storage, for each of these activities we use certain data for the purposes of logging and auditing. This data is handled as global and includes some service and user information to help generate business metrics and usage metrics. The data stored and managed in these centralized components is governed by the Cisco Corporate Information Security guidelines, which require strict adherence related to sharing with third parties, retention, and documentation of this data.

We store content in the region of the organization that owns the space where the content appears. Ownership depends on the type of space:

• Group space—The owner is generally the organization of the person who created the space. We store content in the region of the owner organization.

• Space within a team—The organization of the person who created the team owns spaces created within the team. Spaces created outside of the team and then moved into the team retain their original ownership. We store content in the region of the space owner organization.

• Conversation between two people (nongroup space)—If the people are in different organizations, each organization owns the content that its user posts. If the conversation includes a user from the North America/RoW GEO, we store the conversation content in the North America/RoW GEO.

• Space created by a bot—We assign ownership to the organization of the first nonbot participant, and store the content in the region of the owner organization.
