Why am I not seeing any data?
Check that your Monocle script is correctly installed, your publishable key is valid, and traffic is reaching your application.
Similar questions
Why did my Monocle assessment volume suddenly drop?
A sudden drop in assessment volume is usually caused by a change on your side — a recent deployment, a Content Security Policy (CSP) update, or a Cloudflare configuration change — rather than a Spur outage. Check your worker logs and recent configuration changes first. If volume still looks incorrect after that, contact support@spur.us with the time the drop started and any recent changes you made.
Why is traffic not being blocked?
Monocle does not block traffic by default. Make sure you have implemented enforcement in your system, or configured a supported integration such as Cloudflare.
Why might the Monocle script fail to load?
This is usually caused by mcl.io being blocked by a firewall, DNS filter, or endpoint security tool. Confirm the domain is allowlisted, and test in an incognito window or from another network to isolate the cause.
Why is my traffic marked as a VPN or proxy?
Monocle identifies traffic based on known infrastructure, behavior, and network signals. In some cases, shared networks or ISP routing may appear similar to anonymized traffic.
What is the difference between using Monocle to monitor vs. enforce traffic decisions?
Monitor is passive: Monocle provides visibility into how users connect to your application without impacting users or taking any blocking action. Enforce applies actions such as blocking or allowing traffic based on Monocle's assessments. Most users start with a monitoring phase before configuring and enabling enforcement.
