"Is Teams, Zoom or Google Meet the most secure?" is the wrong question. All three are capable enterprise platforms, and your real security depends on configuration and governance, not the logo. The useful move is to compare them on a common checklist and harden whichever you use. ## The comparison framework - Access control: SSO, phishing-resistant MFA, and how external/guest access is managed. - Data protection: encryption in transit and at rest, retention, data residency, DLP. - Meeting security: waiting rooms, locks, and control over who can admit, share or record. - Third-party app governance: how apps and integrations that request access to your data are approved and controlled. - Admin & audit: the admin controls and audit logging available. Teams, Zoom and Meet differ in the specifics, but the questions are identical. ## The risks they all share - Over-broad guest/external access exposing internal conversations and files. - Unmanaged third-party apps requesting broad access to your data. - Recordings, chats and files sprawling without retention or access controls. Governing these across whichever tools you use matters more than picking a "winner." ## Hardening checklist Enforce SSO + phishing-resistant MFA, manage guest access tightly, set meeting-security defaults, govern third-party apps with an allowlist and review, apply retention/DLP to recordings and files, enable audit logging, and re-review periodically.
