PerimeterX
PerimeterX, rebranded as HUMAN Security, verifies 20 trillion weekly interactions to stop bot attacks, ad fraud, and account takeover.
PerimeterX
PerimeterX was founded in 2014 and later rebranded as HUMAN Security, dropping the original name in favor of a tagline centered on distinguishing real users from bots. The firm positions itself as the trust layer for digital experiences, embedding its technology across ad impression, application, account, and transaction touchpoints. The platform covers ad fraud detection, account takeover prevention, scraping protection, transaction abuse, and client-side supply chain security. HUMAN verifies over 20 trillion weekly interactions across 3 billion unique devices and its decision engine analyzes 2,500+ signals per interaction with more than 400 algorithms. Named portfolio companies are not disclosed by the firm; the platform is sold to leading enterprises globally. The firm's threat intelligence arm, Satori, has publicly disrupted operations including BADBOX 2.0 (affecting 1 million devices) and the Konfety ad fraud ring (generating 10 billion fraudulent requests daily). HUMAN operates from San Mateo, California. The firm received the top scores across nine criteria in The Forrester Wave: Bot Management Software Report, Q3 2024, and was ranked #1 in G2's Bot Detection and Mitigation category. No team size, offices, or adjacent vehicles are disclosed. Unlike many bot-detection vendors that focus on a single attack vector, HUMAN spans the entire digital customer journey and provides an integrated platform for advertising, application, account, and transaction protection. Its Satori threat intelligence unit differentiates through public takedowns of large-scale cybercrime operations.
