Cloudflare's **Browser Integrity Check (BIC)** looks for common HTTP headers abused most commonly by spammers and denies access to your page.

It also challenges visitors without a user agent or with a non-standard user agent such as commonly used by abusive bots, crawlers, or visitors.

## Disable Browser Integrity Check

**BIC** is enabled by default.

### Disable globally

To disable **BIC** globally for your zone:

1. Log into the [Cloudflare dashboard](https://dash.cloudflare.com).
2. Select your account and zone.
3. Go to **Security** > **Settings**.
4. For **Browser Integrity Check**, switch the toggle to **Off**.

### Disable selectively

To disable **BIC** selectively, you can set up a [firewall skip rule](https://developers.cloudflare.com/waf/custom-rules/skip/).

Also, use a [Configuration Rule](https://developers.cloudflare.com/rules/configuration-rules/) to selectively enable or disable this feature for certain sections of your website using a filter expression (such as a matching hostname or request URL path).
