A webinar is a live or recorded online session that lets a host present information, demonstrate software, and interact with remote participants through features such as chat, questions, screen sharing, and polls. In information security, webinars commonly support awareness training, technical briefings, and demonstrations of defensive tools or attack techniques.
Security practitioners should treat webinar invitations and registration pages as potential phishing lures: verify the sender and destination before signing in or downloading meeting software. The webinar platform itself can expose sensitive material through weak authentication, excessive attendee permissions, unsecured recordings, screen sharing, chat, or participant data collection. Hosts should use authenticated access where appropriate, limit presenter privileges, moderate questions and uploads, protect recordings, and minimize retained registration data. Training webinars may also disclose internal procedures or vulnerability details, so content and access should be classified before publication and managed under the organization’s privacy and information-handling requirements.
