Browser reports in CentralCSP

Where each browser report type lands, which ones to act on first, and how to cut the noise a newly connected site produces.

Last update:

This section has one page per report type, plus a raw Explorer for everything the browser sent. Reports are kept for 90 days.

Every report type appears under Reports in the website sidebar:

Which page answers what

Each report page answers a different question:

PageUse it to
CSP violationsBuild a policy that matches what your pages load
CSP hashesFind what runs on your pages and whether it changed
Integrity violationsFind scripts loading without verification
Permissions PolicySize a features policy before enforcing it
Document PolicyFind legacy APIs your documents still use
DeprecationsFix what a future browser release will break
InterventionsCheck your code handles what the browser overrode
CrashesFind pages that crash the browser tab
Connection allowlistControl where your pages connect out to
COEPClear the list blocking cross-origin isolation
COOPCheck popup logins survive an opener policy
Network errorsSee failures your server logs cannot contain

A page for a policy you have not deployed is simply empty. Which pages exist at all depends on the report types your plan includes.

Where to start on a new site

On a new site, work the pages in this order:

  1. CSP violations, one directive at a time. Noisiest page, most useful.
  2. Deprecations. Small, and every entry is code you will have to change anyway.
  3. Network errors, if you serve a large audience.

Leave the rest until you deploy the matching policy.

Cut the noise before reading it

A first batch on a site with no prior CSP looks alarming and mostly is not. The generated policy allows nothing beyond your own origin, so every font, image, and third-party script reports. That list is inventory, not incidents.

Two things do deserve immediate attention: violations you cannot explain from your own code, and anything on a payment page.

Browser extensions are the largest source of unfixable noise, because the injected code is not yours. Drop them under Settings > Ingestion rather than working around them on every page. For more information, refer to Ingestion filters.
