About
Source Defense is a cybersecurity company specializing in client-side website security and data privacy compliance.

The platform supports PCI DSS 4.0 compliance requirements (sections 6.4.3 and 11.6.1) and is designed for e-commerce, financial services, and any organization collecting sensitive customer data online. Founded in 2014 and headquartered in Rosh Ha'Ayin, Israel, the company has raised $37.5M across three funding rounds including a $27M Series B in 2022.
