Frequently Asked Questions — Cisco Webex vs Zoom Phone
Is Cisco Webex or Zoom better for enterprise UCaaS?+
Cisco Webex is generally better for organizations with existing Cisco infrastructure, strict compliance requirements (FedRAMP, FIPS), and a need for deep integration with Cisco networking. Zoom is better for organizations prioritizing user experience, AI Companion included at no cost, and market-leading video meeting quality. Both are enterprise-grade platforms — the right choice often comes down to existing infrastructure investment.
Is Cisco or Zoom more secure?+
Both offer enterprise-grade security. Cisco Webex has FIPS 140 certification, FedRAMP authorization, and end-to-end encryption — making it the stronger choice for regulated industries and government. Zoom also offers end-to-end encryption and enterprise security, with significant security improvements since 2020. For the highest compliance requirements, Cisco typically leads.
Can Cisco Webex replace Zoom Meetings?+
Yes — Webex Meetings is a full-featured video conferencing platform that competes directly with Zoom. For organizations already in the Cisco ecosystem, replacing Zoom with Webex Meetings consolidates the stack and improves integration with Cisco Calling. However, Zoom has a larger install base and may require more change management to displace.
