What Is Domain Filtering?
Domain filtering is a security and audience management feature built into the ON24 Intelligent Engagement Platform. It enables webinar organizers to define which email domains are permitted—or restricted—during the registration process.
For example, marketers can use domain filtering to exclude personal email addresses (like Gmail or Yahoo) when hosting business-only events or to restrict access to competitive organizations. Conversely, it can also be configured to whitelist specific partner or customer domains, ensuring only invited participants gain access.
By managing event participation through domain filtering, marketers maintain data security, brand integrity, and targeted audience alignment, especially in account-based and customer-exclusive campaigns.
Why It Matters
- Event security: Prevent unauthorized or unintended registrants from accessing sensitive information.
- Audience qualification: Ensure only approved organizations or partners participate.
- Data protection: Strengthen compliance with privacy and data-sharing policies.
