SiteWall - 2026 Pricing, Features, Reviews & Alternatives

SiteWall is a client-side security and third-party script governance platform for organizations that need visibility and control over what runs in customers’ browsers. It continuously observes first- and third-party JavaScript resources, identifies providers and dependencies, maps load flows and network activity, monitors browser API usage, and records how scripts behave across sessions and over time.

Security, AppSec, compliance, privacy, and engineering teams can use SiteWall to investigate provider and resource activity through detailed profiles, execution context, security scoring, performance measurements, incident history, and forensic telemetry. The platform surfaces anomalies, risky behavior, security issues, unexpected changes, and performance impact so teams can assess browser-layer risk with stronger context.

SiteWall supports zero-trust policies for newly discovered resources, provider and resource blocking, geographic and network restrictions, domain controls, and granular browser permissions for storage access, network requests, script execution, DOM modification, clipboard access, device features, user profile data, and other browser capabilities. Permissions can be derived from observed resource usage, helping teams apply least-privilege controls with less manual configuration.

Integrations connect SiteWall with existing SIEM, observability, security, and operational workflows. Continuous monitoring, requirement-level actions and evidence, audit trails, and downloadable reports support PCI DSS 4.0.1—including payment-page script governance workflows related to requirements 6.4.3 and 11.6.1—as well as GDPR and ISO 27001 programs. SiteWall helps organizations discover client-side assets, control third-party JavaScript risk, protect sensitive browser data, maintain website performance and functionality, and produce audit-ready evidence without replacing their existing security stack.
