As answered by people managing Deflect.bot and Opalstack.
Deflect.bot's answer
My name is Alex and I am a co-founder of Deflect. For the past 3 years, I used to work in the reverse engineering fields, specifically for website antibots such as Deflect. In that time, I realized how often companies will make a simple script with a proof-of-work challenge that offers no protection, and call that enterprise-grade and give it unreasonable pricing. Since then, I've applied all my knowledge from best methods and new in-house research to provide real security to websites of all sizes.
Deflect.bot's answer
Deflect operates on a zero-friction belief, that any bot can be spotted without ever asking your user to solve a challenge. That by itself is NOT new, but it's never been done right. Every challenge we serve is so dynamic and uses methods so newly-founded in the field, that it would take attackers, months to bypass it properly.
Deflect.bot's answer
Compared to simple, easier products such as reCaptcha and hCaptcha, we offer real security that can't be bypassed by solvers such as (capsolver.com).
Compared to the few enterprise gatekept antibot, we offer the same detection quality and even faster speeds at an average of x10 less the price.
Deflect.bot's answer
Anyone with a site where vulnerable actions can be abused by bots, is someone we can help protect.
Bot attacks often start with simple things such as Free Trials, Newsletter Abuse, SMS pumping and more.
These are often done to either exploit a freemium service or from competitors trying to sabotage your business.
