Source Defense offers a security and compliance platform that protects client-side web applications by detecting, protecting against, and preventing vulnerabilities originating in JavaScript and third-party code. The patented Source Defense Platform applies a zero-trust model that extends security beyond the network to the client-side, addressing third-party digital supply chain risk. It serves leading organizations across financial services, healthcare, hospitality, and retail, and supports compliance regimes such as PCI, HIPAA, and GDPR. The company is led by CEO Dan Dinnar and is based in Rosh Ha’ayin, Israel and New Haven, Conn. Source Defense currently protects nearly a billion monthly site visits and prevents approximately 6 billion quarterly violations of security and compliance policies. The company plans to use the new funds to accelerate growth with investments in Sales, Marketing, Alliances, and Research and Development. Source Defense provides a website security solution focused on preventing malicious activity originating in website supply chain vendors, using its patented VICE Client-side Web Security Platform. Its technology, built on machine learning and industry best practices, offers a fully automated and dynamic solution that controls access and permissions of various dynamic components operating on a website. The company says it has more than tripled its sales in the past year and has expanded its R&D team, established strategic channel partnerships, and strengthened its executive team. Source Defense cites deployments with several Fortune 500 companies and a recent deployment at a Fortune 50 company as evidence of enterprise traction. The firm plans to use the new funding to accelerate growth and further enhance its VICE platform to meet growing market demand. CEO Dan Dinnar and quotes from investors emphasize the solution’s role in addressing Magecart/formjacking client-side attacks and regulatory compliance needs (GDPR, PCI, CCPA, HIPAA). Source Defense provides a website security platform that stops JavaScript-based website card skimming attacks and other third-party supply-chain hacks with a real-time, proactive prevention solution. Its technology controls third-party access and enforces access policies to prevent malicious activity before it begins. The platform integrates via a copy-and-paste JavaScript snippet, sets policies automatically without administrator involvement, and is designed for low-touch management while preserving site integrity and performance. The company closed a Series A financing that brought its total funding to $10M, with backers including AllegisCyber, Jerusalem Venture Partners, Global Brain and Connecticut Innovations. It intends to use the capital to accelerate its go-to-market strategy. Source Defense has opened a US headquarters in Stamford, Connecticut and a second R&D center in Rosh HaAyin, Israel and plans an intensive hiring campaign in both locations.
