A

Akamai

Akamai Bot Manager protection
One of the strictest anti-bot systems out there. Protects banking, corporate sites and parts of e-commerce. Even premium residential typically delivers a 65-80% success rate against Akamai.

Anti-bot

antibot system protection
Software systems that detect automated traffic: Cloudflare, Akamai, PerimeterX, Datadome, Imperva. They analyse headers, fingerprints, TLS handshakes, behavioural patterns. The harsher the anti-bot, the more expensive the proxy you need (residential/mobile instead of datacenter).

Anti-detect browser

tooling
A specialised browser that builds a unique browser fingerprint per profile — Multilogin, Dolphin Anty, Adspower, GoLogin. Used for multi-account work in combination with mobile proxies.

API rotation

technical
Changing the IP address by calling a separate API endpoint (rather than rotating on a timer or per request). Lets you rotate programmatically — for example on receipt of an HTTP 429.

ASN

Autonomous System Number network
A unique identifier for a network on the internet (e.g. AS16509 for Amazon AWS, AS6939 for Hurricane Electric). Anti-bot systems look at the ASN of an IP: if it belongs to a data centre, that's a bot signal. Residential ASNs (Comcast, Vodafone, BT) look natural.
