Best anti-fraud system?

[kikk2020]

So Iam looking for a good anti-fraud system that can sniff out most fake leads and bot traffic etc etc. Any good tips would be appriciated.

Google CAPTCHA can help, especially if you have bots that submit forms.

Cloudflare has multiple services tackling this problem: WAF, rate limiters, Bot management etc. These usually go at the network level (lower than Google CAPTCHA).
