Zero Trust just means you stop inherently trusting your private network and verify every user/device/request regardless. If you opt in to using Cloudflare to do this then it requires running Cloudflare software.
Thats one interpretation... ZT also posits assuming the network is compromised and hostile, that also applies to CF and their cloud/network. It blows my mind that so many solutions claim ZT while mandating TLS to their infra/cloud, you can trust their decryption of your date, and worst IMHO, they will MITM your OICD/SAML key to ensure the endpoint can authenticate and access services... that is a hell of a lot of implicit trust in them, not least of them being served a court order to decrypt your data.
Zero trust done correctly done not have those same drawbacks.
Zero Trust means you stop trusting your private network, and start trusting Cloudflare, and installing their special root certificate so they can MITM all your web traffic. To keep you safe.
Technically I guess that's "zero trust" in the sense of meeting the requirement of not trusting internal connections more than external ones, but in practice I guess "zero trust" also typically entails making every connection go through the same user-based authentication system, which uploading specific keys to specific servers manually definitely doesn't achieve.
