What it does

Watches outbound DNS resolution from your network to surface SaaS applications employees are reaching that have never appeared before, catching shadow-IT adoption at the moment of first use rather than after the invoice lands.

When to use it

Use it when you run Cloudflare Gateway/Zero Trust and want a daily feed of newly contacted SaaS domains so security can decide whether each tool needs onboarding, a DLP policy, or a block.

How it works

  1. 1A daily schedule triggers the discovery sweep.
  2. 2A Cloudflare action pulls the prior day's Gateway DNS query logs.
  3. 3A logic step classifies domains as SaaS/signup-related and drops any domain already present in the known-domains history, keeping only first-seen hosts.
  4. 4Each new domain becomes a Linear issue with the resolving user count and example query timestamps.
  5. 5A Slack alert lists the day's new SaaS domains for the IT team to triage.
