The Cisco Webex white paper details how Zero Trust Security ensures confidential, end-to-end encrypted meetings. Webex builds on 12 years of E2E encryption, adding verified identity and standards-based cryptography. Key features include SFrame for media encryption, Messaging Layer Security (MLS) for group key exchange, and user identity verification anchored outside Cisco. This approach protects against both passive and active attacks. Future enhancements aim for ubiquitous E2E security, decentralized identity, and customer-controlled integrations. Webex enables secure collaboration for enterprises and governments while maintaining usability and flexibility.
