PerimeterX

Leading bot mitigation and application security provider, now part of HUMAN Security

PerimeterX, founded in 2014, was a cybersecurity company that specialized in protecting web applications, mobile apps, and APIs from automated bot attacks, account takeover, and online fraud. The company developed behavior-based detection technology that could distinguish between human users and malicious bots without disrupting the user experience. In 2021, PerimeterX merged with White Ops to form HUMAN Security, creating one of the largest bot mitigation and fraud prevention platforms in the industry. Today, operating under the HUMAN Security brand, the company continues to provide its core bot defense, account protection, and application security solutions to enterprises across e-commerce, financial services, media, and other industries. The platform processes trillions of digital interactions annually, using machine learning and behavioral analysis to detect and prevent sophisticated bot attacks, credential stuffing, web scraping, and ad fraud. While the PerimeterX brand has been largely phased out in favor of HUMAN Security, the technology and solutions originally developed by PerimeterX remain central to the combined company's offerings. The merger positioned HUMAN Security as a comprehensive fraud prevention platform serving both application security and advertising verification markets, with the PerimeterX technology focusing primarily on application-layer protection while the White Ops technology addressed ad fraud and bot detection in digital advertising ecosystems.
