We built SiteWall because the browser has become one of the least visible parts of the modern security stack. By the time a website reaches a customer, third-party scripts can load other resources, access browser capabilities, transmit data, and change behavior—often beyond what teams can see from source code or infrastructure monitoring. SiteWall makes that activity observable and governable. It continuously discovers providers and resources, maps how they load and what they access, detects meaningful changes, and lets teams apply zero-trust and granular policies based on observed behavior. It also turns runtime evidence into clear PCI DSS, GDPR, and ISO 27001 workflows and exportable reports. We’d love feedback from security, engineering, privacy, and compliance teams: where is client-side visibility hardest for you today?
