<p>We released Monitor mode at customers' request so they can test Precursor and the Precursor Interstitial without updating bot score.</p> <p>In <strong>Security</strong> &gt; <strong>Settings</strong>, the Precursor <strong>Status</strong> dropdown now offers <em>Off</em>, <em>Monitor</em>, and <em>Arm</em>. Selecting <em>Arm</em> means Precursor detections can affect bot score and Challenge clearance. Selecting <em>Monitor</em> means Precursor detections do not affect bot score or Challenge clearance.</p> <img src="https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=739,height=235,format=webp/_astro/precursor-monitor-mode-status.CRb5Sudr.png" alt="Precursor Status dropdown with Off, Monitor, and Arm options" loading="lazy" decoding="async" width="739" height="235"> <p>We also separated the Precursor Interstitial from the mode. Set the sitewide default with <strong>Show Interstitial</strong>, then add <strong>Interstitial Rules</strong> to customize it for specific requests. For example, leave <strong>Show Interstitial</strong> off across most of your site, but require an interstitial Challenge on <code>/checkout</code> to enforce a valid session before purchase.</p> <img src="https://developers.cloudflare.com/cdn-cgi/image/onerror=redirect,width=600,height=441,format=webp/_astro/precursor-interstitial-settings.Bpb_aV0o.png" alt="Precursor settings with Show Interstitial off and an Open interstitial rules button" loading="lazy" decoding="async" width="600" height="441"> <p>For more information, refer to the <a href="https://developers.cloudflare.com/cloudflare-challenges/precursor/"><strong>Precursor</strong></a> documentation.</p>
