Reflectiz specializes in identifying vulnerabilities within the client-side layer, an area often overlooked by traditional scanners. It detects known CVEs present in open-source JavaScript libraries utilized on live pages, including transitive dependencies introduced by third-party vendors, and highlights components that are outdated or no longer maintained. In addition, it addresses risks not covered by conventional CVEs, such as a trusted vendor's script being modified upstream without notice, changes in a tag manager that could start capturing payment information, or trackers transmitting personal data to unauthorized endpoints. Unlike typical methods that rely on matching version numbers to a database, Reflectiz monitors the actual behavior of each script at runtime, effectively uncovering both known and unknown risks. Its assessments are conducted continuously on the fully rendered page without the need for periodic scans, code alterations, agents, or access to customer data. The findings align with compliance requirements for PCI DSS 4.0.1, GDPR, CCPA, and HIPAA.
