Cloudflare

Cloudflare is a major internet infrastructure company that provides content delivery, DNS, web application firewall, and bot management services used by a large share of websites and APIs worldwide. For AI governance, it matters because Cloudflare sits in the path of traffic between businesses, their customers, and AI crawlers or model providers, so its policies on AI bot blocking, data handling, and network-level controls can directly affect how an organization's content is accessed and how its own AI services are exposed.
