CloudFlare

Cloudflare is primarily known for its website security and performance optimization services. While they do offer some features that could be indirectly related to advertising, they are not a dedicated advertising platform or company. Their services, like content delivery network (CDN) and website optimization, can indirectly impact advertising effectiveness by improving page load times and user experience, ultimately leading to better engagement with ads. Cloudflare also offers a feature called "Zero Trust," which includes tools for managing user access and identity, which could be used to target advertising more effectively. However, Cloudflare`s core focus is on security and performance, not directly on advertising.
