Is Zoom’s Lack of End-To-End Encryption a Problem?

This advisory explains that Zoom meetings generally rely on transport-layer (TLS) encryption rather than true end-to-end encryption, meaning Zoom (or an attacker with access to Zoom systems or credentials) could potentially access meeting content. The report assesses the privacy and security implications, warns about the potential for follow-on social engineering attacks, and lists practical mitigations—such as avoiding sharing highly sensitive material in meetings, using unique meeting IDs and passcodes, restricting file sharing to approved services, and reinforcing phishing/AV controls.
