Keep firewall rule reviews visible in Slack

Make a firewall rule review easier to act on by sharing the outcome and any checks still needed with your team.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Post message to channel

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

Rule reviews can leave open questions behind when the findings stay outside the team conversation.

  • Share relevant review findings in Slack.
  • Call out unverified assumptions and remaining checks.
  • Make ownership and follow-up easier to discuss.

Setup

Build it in a few focused steps.

  • 1Connect Cloudflare and Slack in Notis once.
  • 2Create an automation and describe how to review firewall rule information and summarize findings and open checks in Slack.
  • 3Choose the Notis webhook trigger.
  • 4Choose where run reports should go.
  • 5Test with one real firewall rule review example.

Questions about this workflow

Can the workflow determine whether a rule is safe?

It can report the available information, but safety depends on context and evidence that may not be present. Ask it to identify what needs human verification.

What starts the review?

An HTTP request to the Notis webhook starts it; there is no Cloudflare trigger event listed for this package.
