About
ALTCHA is a modern security and privacy-focused platform built to defend web services from bots and abuse — without compromising the user experience. At the heart of its ecosystem is ALTCHA Sentinel, a next-generation threat detection and mitigation system designed to protect websites, APIs, and applications from automated attacks, spam, and other forms of abuse.
ALTCHA Sentinel stands out by combining adaptive machine learning, behavioral analysis, and smart verification techniques. It doesn’t rely on intrusive CAPTCHAs or outdated blocking tactics; instead, it works invisibly behind the scenes, analyzing traffic patterns in real time to identify and stop threats before they cause harm. Sentinel protects critical entry points like sign-up forms, login pages, and comment sections — all while keeping the experience seamless for real users.

About
Turnstile delivers frustration-free, CAPTCHA-free web experiences to website visitors - with just a simple snippet of free code. Moreover, Turnstile stops abuse and confirms visitors are real without the data privacy concerns or awful UX that CAPTCHAs thrust on users.
Give your web visitors an even better experience. Turnstile confirms they are real with no visual puzzle - totally transparent to visitors.
Turnstile always preserves the privacy of web visitors on your site - without sacrificing effectiveness. Unlike other CAPTCHA options, we never harvest data for ad retargeting.
Deploy in minutes with just a quick code snippet - and totally free of charge.
Humans spend about 500 years each day solving CAPTCHAs - wasting time and creating frustration. This is why Cloudflare built a better alternative to CAPTCHAs with Managed Challenge and now Turnstile.
