Prolexic Technologies is a privately held American information technology and services company headquartered in Hollywood, FL. Prolexic is the world’s largest provider of on-demand, cloud-based Distributed Denial of Service (DDoS) mitigation services. Prolexic protects the Internet-facing infrastructures – such as e-Commerce web sites – against all known types of DDoS attacks at the network, transport, and application layer through its proprietary mitigation technology tools, globally dispersed network traffic scrubbing centers, and real-time monitoring and mitigation by DDoS mitigation experts based at its 24/7/365 Security Operations Center (SOC).

The company was founded in 2003 to provide services to the online gaming industry. At that time, it was the industry that received the highest volume of DDoS attacks as well as some of the most vicious ever launched. But as DDoS evolved from extortion to “for hire” and then became mainstream Prolexic expanded its reach. As more businesses and government agencies were subjected to crippling DDoS attacks, more turned to Prolexic. The company currently protects clients in the e-Commerce, Financial Services, Software as a Service, Airlines/Hospitality, Online Gaming and Public Sector industries. In fact, six of the world's 10 largest banks (by market capitalization) trust Prolexic to protect their businesses.
