How it runs

The automated pipeline, trigger to output.

  • TriggerDaily schedule starts fleet-wide audit
  • ActionList zones and fetch WAF rules from CloudflareCloudflareCloudflare
  • LogicDiff each zone vs its baseline; tag drifted zones
  • ActionAppend findings to Snowflake drift ledgerSnowflakeSnowflake
  • OutputPost Slack rollup of drift across all zonesSlack

What it does

Gives you a fleet-wide view of WAF configuration drift. It iterates over all zones in your Cloudflare account, diffs each one against its stored baseline, and appends every finding to a Snowflake audit table so you have a queryable history of who let rules drift and when, plus a daily Slack summary.

When to use it

Use it when you manage dozens of zones and need compliance-grade evidence, not just one-off alerts. Perfect for SOC 2 or PCI audits where you must prove firewall configuration is monitored continuously across every property.

How it works

  1. 1A scheduled trigger starts the daily fleet audit.
  2. 2Cloudflare returns the zone list and the live WAF rules for each zone.
  3. 3A logic step diffs every zone against its baseline and tags each result as in-sync or drifted.
  4. 4All findings are inserted into a Snowflake drift-ledger table for long-term audit history.
  5. 5A Slack rollup reports total zones scanned, count drifted, and links to the worst offenders.
