Source Defense is a security, compliance, and performance optimization platform for any website that collects sensitive data or is transaction-oriented. It addresses a ubiquitous gap in managing 3rd party digital supply chain risk with a zero-trust model that extends security beyond the network to the edge/client-side. Source Defense is the leader in what Gartner has dubbed “web application client-side protection.” The platform protects leading organizations in the financial, healthcare, hospitality, and retail markets from the threat of JavaScript-based attacks such as Magecart, digital skimming, credential harvesting and click-jacking. Source Defense secures nearly one billion transactions and prevents about two billion compliance policy violations per quarter.
