What PerimeterX does
PerimeterX was a web application security vendor founded in 2014 and headquartered in San Mateo, California, focused on detecting and mitigating automated threats — bots, credential stuffing, account takeover, and content scraping — across consumer-facing websites and APIs. Its technology centered on behavioral and device signal analysis to distinguish human from non-human traffic, with deployment integrated into customers' application stacks.
In 2024, PerimeterX was acquired by HUMAN Security and its capabilities absorbed into the HUMAN Defense Platform, a unified subscription SaaS offering that now spans advertising protection, application protection, and transaction protection. The platform analyzes 2,500-plus signals per interaction through 400-plus adaptive machine-learning algorithms, processing over 20 trillion digital interactions weekly across roughly 3 billion unique devices. Solutions are organized around Bot Detection & Mitigation, Account Takeover, Scraping, Ad Fraud, Transaction Abuse, Fake Accounts, and — most recently — LLM & AI Agent Governance under the AgenticTrust product family.
The combined entity sells through direct enterprise sales with quote-based annual subscription pricing, supplemented by technology and channel reseller programs. Target verticals include Financial Services, Retail & E-Commerce, Ad Tech Platforms, Digital Publishers, SaaS Platforms, Streaming & Gaming, Travel & Hospitality, Healthcare, Education, and the Public Sector, with named enterprise customers such as LinkedIn, The Trade Desk, Priceline, Samsonite, TripleLift, Magnite, Sweetwater, and Venatus Media. Offices are located in New York City, Santa Clara, Miami, Dallas, Tel Aviv, and London.

PerimeterX competitors and assessment
Company assessmentBroad incumbents
