It looks at details like the cipher suites provided, the order of negotiation, and other low-level traits. Bots frequently recycle default or suspicious configurations that vary from those used by real internet browsers.
This includes the exact browser version, running system, set up typefaces or extensions, and even subtle hardware characteristics.

However, if the JavaScript difficulty fails (meaning Cloudflare concludes the customer is most likely to be a bot), it will intensify to showing a Turnstile CAPTCHA for human confirmation: Now, you are back to what you saw in the previous circumstance.
This page is secured by the Cloudflare WAF, so the automated JavaScript-based confirmation procedure will right away start. In the background, a series of POST demands are exchanged with Cloudflare's endpoints, transferring encrypted information within their payloads: The specific contents of these payloads are not openly recorded.
