Anti-bot
antibot system

A hash of the client's TLS handshake. Unique for each combination of OS, browser and version. Datadome and Akamai use it to detect automated traffic regardless of IP.
S
Success rate
performance
Percent of HTTP 200 responses out of 1000 benchmark requests. Top providers: 98-99% on standard targets, 65-78% on Datadome.
