Source Defense operates within the computer and network security sector, focusing on protecting commercial websites from client-side threats introduced by third-party vendors. Many websites rely on dozens of external vendors, which can create vulnerabilities on the client side that leave sites exposed. The company employs a real-time sandbox isolation approach to curb malicious activity that may originate from website supply chain vendors. Based in Beersheba, in the Southern District of Israel, Source Defense serves businesses with websites that rely on third-party integrations and seeks to strengthen their client-side security. A recent development noted in industry coverage indicates that Mastercard became a client in March 2026, demonstrating engagement with enterprise customers.
