## Use it in a design

```yaml
nodes:
  - { id: "cloudflare-waf", component: "cloudflare-waf" }
```

## Source (`component` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../../schema/component.schema.json
# Cloudflare WAF: the Free Managed Ruleset is deployed automatically on every new zone, so the WAF
# filters (not just logs) out of the box ("Managed Rules", "Get started"); OWASP defaults to
# paranoia level PL1 and a score threshold of 40 ("OWASP Core Ruleset - Concepts").
