Some customers are hesitant to use Turnstile. Their primary concerns are:
Does Turnstile work in China? Google CAPTCHA is blocked from there so our websites in China are using a very outdated solution that has security holes. We are wondering if China (or other countries) block the use of Turnstile?
Does Turnstile work with proxies? Many of our users use EZProxy which effectively means they share IP addresses and it does URL rewriting.
Turnstile supports PAT, but doesn’t rely exclusively on this to make decisions. Turnstile is compatible with desktop browsers, Android/iOS browsers, and more – regardless of PAT. You do not need to prepare a fallback option yourself.
There are several reports of Turnstile not working correct in Safari. I don’t know if that’s changed but I haven’t seen any reports of those issues being resolved. I mention that due to the mention of iOS in blurb you quoted.
