Our Mission

Enabling companies to leverage their websites to drive business forward, further and faster, while ensuring security, compliance, and customer data privacy.

Our Story

The Source Defense story began when its co-founders encountered security and data breaches along their careers, generated by website supply chain vendors they worked with. They looked for a solution, only to realize no real one exists.

Being devoted problem solvers, our founders decided to start working on a solution themselves and founded Source Defense back in 2014.

Today, Source Defense provides a unique website security solution focused on preventing malicious activity originating in website supply chain vendors. These include analytics, advertising, chat, payment solutions and more. Every website today uses such tools to enhance user experience, engagement and insights.

Using a first-of-its-kind technology based on machine learning and industry best practices, Source Defense provides its customers with a fully automated and dynamic set of rules and policies that control access and permissions of all Javascript-based 3rd party tools operating on their website.

This way, website supply chain vendors may only deliver the intended value and experience and cannot serve as an attack surface for malicious data extraction or website alteration.
