SiteWall by CellWall is a client-side security, third-party JavaScript governance platform that helps organizations discover, monitor, control, and prove what happens on their websites. Built for CISOs, CTOs, application security, engineering, privacy, and compliance teams, SiteWall provides continuous visibility into first-party and third-party scripts, providers, resources, network requests, browser APIs, storage access, and runtime behavior.
SiteWall automatically discovers every observed provider and JavaScript resource running on a monitored website. It creates a live third-party script inventory with provider profiles, resource history, loading relationships, security scores, performance data, API access, network destinations, activity history and past incidents. Visual exposure maps and load-flow analysis show which third parties load additional code, what browser capabilities they use, and where data may be transmitted. Session-level evidence supports investigation and validation of the real client-side attack surface.
Continuous client-side monitoring detects anomalous behavior, unauthorized changes, risky resource activity, new scripts, integrity issues, and operational problems that may affect website security, privacy, performance, or functionality. SiteWall centralizes anomalies, issues, alerts, and runtime evidence so teams can move from detection to investigation and response without relying only on periodic scans or static source-code analysis.
SiteWall also provides policy enforcement and runtime protection. Teams can apply Zero Trust defaults to newly discovered resources, automatically derive permissions from observed usage, configure granular browser capability controls, restrict storage and network access, define geographic and domain-based network policies, and manage controls globally or for individual providers and resources. If a third-party provider becomes compromised or affects website reliability, teams can restrict or block it while preserving a clear policy and audit trail.
For compliance and audit readiness, SiteWall maps observed client-side activity to requirements and evidence for PCI DSS, GDPR, and ISO 27001. Dedicated workflows support script inventory, change detection, authorization, business justification, integrity verification, third-party assessment, requirement-level findings, remediation actions, readiness tracking, and exportable reports. This replaces fragmented screenshots and manual evidence collection with continuous, audit-ready proof based on actual browser behavior.
SiteWall integrates with existing security, monitoring, and operational workflows, including SIEM and observability tools. By combining third-party JavaScript discovery, client-side attack-surface visibility, browser runtime monitoring, anomaly detection, policy enforcement, incident investigation, compliance automation, and reporting, SiteWall helps organizations discover, control, and prove what happens in the browser.
