Add Captcha/Challenge to web application firewall
We'd love to use WAF, but it is missing a captcha/challenge mechanism.
e.g. after X amount of attempts - put a recaptcha image or "I am not a robot" checkbox type functionality
Ideally this threshold would have some advanced settings or configuration - based on throughput or anaylitics of traffic.
we currently use cloudflare, and this is holding us back from switching. some appliances (e.g. barracuda WAF) include it - but they are quite pricey to deploy within Azure compared to WAF.
