In addition to using category and classification blocks and overrides to limit user access to URLs, you can set a daily quota by category, category group, or classification. Quotas allow access for a specified length of time or a specific bandwidth, and are calculated separately for each user. Quotas are reset daily at midnight.
Quotas can be set for the Monitor, Warning, or Authenticate actions. Once the quota is reached, the traffic is blocked and the replacement message page displays.
Quotas are only available in proxy-based inspection mode.
The following example shows how to set a time quota for the education category (category 30).
- Go to Security Profiles > Web Filter and click Create New, or edit an existing profile.
- For Feature set, select Proxy-based.

- Go to a website that belongs to the education category, such https://www.harvard.edu/. You can view websites in that category at the moment.
- In FortiOS, go to Dashboard > FortiGuard Quota Monitor to check the used and remaining time.
- When the quota reaches its limit, traffic is blocked and the replacement page displays.
