What it does

This workflow guarantees you can always roll a WAF ruleset back to any prior state. Whenever a ruleset changes, it captures a complete, timestamped snapshot of the new and previous versions and stores them as immutable objects, plus a queryable change record.

When to use it

Use it as the safety net beneath all your other WAF processes. Even ad-hoc dashboard edits get captured, so a restore is always a single known artifact away rather than a frantic reconstruction.

How it works

  1. 1A Cloudflare change event triggers the workflow on any ruleset edit.
  2. 2The workflow fetches the full current ruleset definition for the affected zone.
  3. 3A logic step builds a timestamped snapshot bundling the new state and the prior version ID.
  4. 4The snapshot JSON is written to versioned object storage in AWS S3.
  5. 5A row capturing the change, actor, and snapshot location is inserted into Postgres for fast lookup.
  6. 6A brief confirmation with the restore reference is posted to the ops Slack channel.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect CloudflareWorkers, Pages, R2, KV — the edge stack.
  2. 2
    Connect AWS S3Buckets, objects, signed URLs.
  3. 3
    Connect PostgresAny Postgres URL — query, write, migrate.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
