# CellWall > Browser-layer security, privacy governance, and compliance evidence for modern websites. CellWall helps teams inventory browser resources, investigate session-level behavior, configure resource and network policies, measure third-party performance, and produce compliance evidence. Product capabilities depend on deployment mode and configured policies; CellWall does not guarantee perfect detection or regulatory compliance. Last reviewed: 2026-09-05. ## Core Products - [SiteWall](https://cellwall.io/en/products/sitewall): SiteWall by CellWall is a client-side security and third-party script governance platform for monitoring and controlling the code that executes in website visitors' browsers. - [CookieWall](https://cellwall.io/en/products/cookiewall): Consent configuration, identifier discovery, privacy inventory, and consent enforcement. ## Key Solutions - [Third-party Script Monitoring](https://cellwall.io/en/solutions/third-party-monitoring): Observed resource inventory, provider dependencies, behavior and rule-based scores. - [Client-side Security Alerts](https://cellwall.io/en/solutions/alerting-incident-response): Issue/anomaly count thresholds, configured notification delivery and delivery history. - [Notification Integrations](https://cellwall.io/en/solutions/integrations): Configured Email, Slack, Teams and Discord delivery paths. Catalog entries do not establish native SIEM, Jira or deployment automation. - [Third-party Script Metrics](https://cellwall.io/en/solutions/metrics-analytics): Historical resource measurements, score trends and average issue-close time, not forecasting. - [Bot Impersonation Context](https://cellwall.io/en/solutions/bot-impersonation): Browser-side investigation context, not a bot-management, CAPTCHA or fraud-prevention service. - [Real-time Monitoring](https://cellwall.io/en/solutions/real-time-monitoring): JavaScript security monitoring with browser API, network, error and timing evidence; issue and anomaly investigation; configured count-based alerts via email, Slack, Microsoft Teams and Discord. - [Compliance Reporting](https://cellwall.io/en/solutions/compliance-reporting): Evidence and reporting workflows that can support assessments. - [Policy Enforcement](https://cellwall.io/en/solutions/policy-enforcement): Configurable allow/block, browser-capability, and network-destination policies. ## Use Cases - [Browser supply-chain risk management](https://cellwall.io/en/use-cases/browser-supply-chain-risk-management): Map direct and indirect browser dependencies, assess security and reliability changes, review the observed website scope, and coordinate a scoped supply-chain response. - [Client-side attack-surface management](https://cellwall.io/en/use-cases/client-side-attack-surface-management): Continuously map browser resources, dependencies, capabilities, destinations, and change; prioritize exposed edges and maintain accountable review. - [GDPR browser data governance](https://cellwall.io/en/use-cases/gdpr-browser-data-governance): Map third-party scripts and browser data flows, apply least-privilege controls, investigate changes, and preserve technical evidence that supports GDPR accountability. - [Incident response and containment](https://cellwall.io/en/use-cases/incident-response-containment): Correlate browser-side change, scope affected sessions, apply reviewed containment, and preserve evidence for investigation and recovery. - [ISO 27001 browser security](https://cellwall.io/en/use-cases/iso-27001-browser-security): Monitor client-side assets, third-party providers, configuration changes, and browser behavior while preserving evidence that supports relevant ISO/IEC 27001 controls. - [Payment-page and digital-skimming protection](https://cellwall.io/en/use-cases/payment-page-digital-skimming-protection): Monitor checkout scripts, sensitive-field access, behavior changes, and network destinations to investigate and contain browser-side digital-skimming risk. - [Payment-page security](https://cellwall.io/en/use-cases/payment-page-security): Discover payment-page scripts and dependencies in the browser, enforce deliberate boundaries, investigate unexpected changes, and retain technical evidence. - [PCI DSS payment-page security](https://cellwall.io/en/use-cases/pci-dss-payment-page-security): Monitor payment-page scripts, detect browser-side changes, manage policies, and collect evidence that supports PCI DSS v4.0.1 Requirements 6.4.3 and 11.6.1. - [Sensitive-data exfiltration prevention](https://cellwall.io/en/use-cases/sensitive-data-exfiltration-prevention): Trace browser access and outbound destinations, investigate unexpected script behavior, and apply scoped controls to reduce client-side data-exfiltration risk. - [Third-party performance and reliability](https://cellwall.io/en/use-cases/third-party-performance-reliability): Review third-party resource load, execution, errors, observed successful-response rates, and dependency signals with browser-side provider context. - [Third-party script governance](https://cellwall.io/en/use-cases/third-party-script-governance): Build a live website script inventory, map third-party behavior and dependencies, apply least-privilege browser policies, and retain governance evidence. - [Website privacy and consent assurance](https://cellwall.io/en/use-cases/website-privacy-consent-assurance): Review captured consent decisions alongside observed browser behavior, investigate possible tracking discrepancies, and use the resulting technical context in privacy reviews. ## Evidence-led comparisons - [CellWall vs cside](https://cellwall.io/en/lp/vs/cside) - [CellWall vs Csper](https://cellwall.io/en/lp/vs/csper) - [CellWall vs Feroot](https://cellwall.io/en/lp/vs/feroot) - [CellWall vs Jscrambler](https://cellwall.io/en/lp/vs/jscrambler) - [CellWall vs Reflectiz](https://cellwall.io/en/lp/vs/reflectiz) ## Resources - [Client-Side Security Hub](https://cellwall.io/en/resources/client-side-security): A structured path through browser-side risks, client-side attacks, third-party JavaScript monitoring, governance, and response. - [Blog](https://cellwall.io/en/resources/blog): Technical articles on front-end security, privacy, and web performance. - [Introducing SiteWall](https://cellwall.io/en/resources/blog/introducing-sitewall-browser-security): Product overview covering browser resource discovery, granular policy control, integrations, and evidence for GDPR, ISO/IEC 27001:2022, and PCI DSS v4.0.1. - [Security Database](https://cellwall.io/en/resources/database): A searchable index of observed web resources and security information. ## Company - [About CellWall](https://cellwall.io/en/company): Company information and contact details.
