In their own words
Kaltura Webinars
Kaltura Webinars is a platform for building, managing, tracking, and automating webinar programs, particularly focused single-session presentations such as seminars, company town halls, and executive presentations. Each webinar can have a branded attendee site for registration and live viewing, with an on-demand recording available afterward at the live event URL. Webinar mode supports up to 300 participants, including up to 10 presenters on stage, though capacity can vary by account configuration and licensing. Depending on the session and setup, engagement tools may include chat, Q&A, polls, reactions, and attendee interactions. Analytics cover attendance and activity such as minutes viewed, reactions, chat messages, poll participation, and Q&A. Registration forms can be customized, and webhook registration is supported. The product is listed for Android, iOS, macOS, web, and Windows. Attendees can join Kaltura Rooms through supported mobile browsers without installing a separate app, although some room tools are unavailable in mobile browsers. Kaltura describes security controls that include HTTPS delivery, AES encryption for HLS, encryption at rest using AWS KMS, and access restrictions.
