Two examples: Encrypted Search and eDiscovery

The E2E encryption approach taken by Webex Teams is especially critical with value-added functionality like search features that rely on “plaintext” (which is unencrypted).

With typical services that handle customer information in plaintext, the more functionality the collaboration provider offers, the more risk that customer information will be breached. But E2E encryption allows Webex to provide services while reducing the attack surface.

An added layer of security: Webex Teams components can’t impersonate users.

Two examples of E2E protection

Encrypted Search

One of the most frequently used features in any messaging system is search. Search in Cisco Webex only requires access to the plaintext of a message once, to build an encrypted index—after that, clients can do searches directly on encrypted data, maintaining maximized E2E encryption.

eDiscovery

This same technology allows Cisco to provide services like eDiscovery with strong security guarantees. So when your compliance officer needs to make sure people are complying with both outside regulatory requirements and your internal policies, he or she can search encrypted content and get the search results in decrypted form.
