Specifc App Requirements

Simply, I want an event-management app where Organizers can create entries. Then the attendee side of the app should be public.

The publisher pro plan does not allow security filters so I am confused on how to achieve my goals. Obviously, I don’t want attendees editing event details or adding any new ones.

Please advice me on what to do. Thank you!

Security filters play no role in the ability of a user to add or edit data.
