What makes Source Defense noteworthy is its unique approach to preventing attacks on websites and web properties of third-party origin. Their SaaS-based platform allows a site owner to set and enforce permissions, receive real-time alerts, and monitor third-party vendors' behavior in real-time. By removing the security considerations from third-party integrations, Source Defense removes person-hours spent on tests and integrations, allowing sites to focus on generating revenues and new opportunities while keeping the site visitors safe and the site in high performance. Source Defense has raised a total of $20.5M in funding over three rounds.
