Every term, explained plainly

A specialized browser that manages multiple isolated virtual profiles, each with its own authentic browser fingerprint, cookie jar, local storage, and dedicated proxy connection.

A globally unique identifier assigned to an autonomous network routing group on the BGP protocol, used by security systems to classify IP legitimacy into residential, datacenter, or mobile tiers.

A composite digital identifier compiled from hundreds of hardware, software, and browser configuration attributes via JavaScript and network protocols to identify devices without cookies.

A browser fingerprinting technique that renders hidden text and geometric graphics on an HTML5 <canvas> element and hashes the sub-pixel rasterization variations to uniquely identify hardware.

An IP address originating from servers in secondary commercial data centers rather than consumer broadband connections, providing maximum speed, high bandwidth, and low cost.

A privacy failure where domain name resolution queries travel outside an encrypted VPN or proxy tunnel directly to an ISP's DNS servers, exposing every website you visit.

A web browser execution mode that runs without a graphical user interface (GUI), controlled programmatically through automated scripts and APIs like Puppeteer, Playwright, or Selenium.

An application-layer proxy designed specifically for web traffic, capable of inspecting headers, caching static assets, and tunneling encrypted TLS traffic using the HTTP CONNECT method.

A static residential IP address hosted directly on high-speed data center servers but registered through commercial agreements with consumer ISPs, combining residential trust with datacenter speed.

An IP address routed through physical 4G, 5G, or LTE cellular connections from mobile network operators, leveraging Carrier-Grade NAT (CGNAT) to provide the highest anti-ban trust score of any proxy type.

An IP address assigned by a consumer Internet Service Provider (ISP) to a residential homeowner, routed through a proxy network to make automated requests appear like genuine human home traffic.

A server that sits in front of one or more web servers, intercepting client requests to handle load balancing, SSL/TLS termination, edge caching, and anti-bot security.

A proxy endpoint or backconnect gateway that automatically changes the outgoing IP address on every HTTP request or after a predetermined time interval.

A flexible, application-independent proxy protocol operating at Layer 5 (Session Layer) that routes any TCP or UDP traffic without reading or modifying application payloads.

A proxy routing configuration that binds a client's requests to the exact same egress IP address for a specified duration, preserving stateful web sessions and login credentials.

A passive cryptographic profiling method that identifies client software by hashing the configuration parameters transmitted in the unencrypted TLS Client Hello packet during HTTPS connection setup.

A critical fail-safe security mechanism in VPN software that immediately shuts down all internet connectivity if the VPN connection drops, preventing unprotected IP leaks.

An advanced browser profiling method that interrogates the WebGL 3D graphics API to extract physical GPU hardware models, shader precision limits, and 3D rendering signatures.

A critical privacy vulnerability where browser WebRTC APIs execute STUN queries that reveal your true public and local IP addresses, completely bypassing VPNs and HTTP proxies.
