Capture, processing, alert delivery and policy enforcement are separate stages. - Review issues by severity, type and status; investigate rule-based client-side anomalies and associated sessions. Configure enabled anomaly rules and presets. - Configure alerts for new issue or anomaly counts exceeding a policy threshold. Deliver through configured email, Slack, Microsoft Teams or Discord channels, with finding summaries and links back to the evidence. - Check notification delivery history for sent or failed status. Notifications do not themselves change browser permissions. - [Learn more](https://cellwall.io/en/solutions/real-time-monitoring) ### Policy Enforcement - Configure resource/provider allow and block policies. - Restrict supported browser capabilities and network destinations for processed scripts. - [Learn more](https://cellwall.io/en/solutions/policy-enforcement) ### Compliance Reporting - Review browser-side inventories, authorization records, observations and configured policy context. Download project-level PCI, GDPR and ISO PDF reports from available records. - These workflows can support PCI DSS, GDPR, and ISO 27001 assessments but do not guarantee compliance. - [Learn more](https://cellwall.io/en/solutions/compliance-reporting) ### Alerting and Incident Response - SiteWall evaluates new issues or anomalies against configured count thresholds. Choose recipients and configured email, Slack, Microsoft Teams or Discord delivery paths. - Notification summaries carry project context, finding count and severity, with finding links and available resource links for investigation. - Review alert delivery history, then investigate findings and available sessions before deciding on supported policy changes. Sent status is not human acknowledgment; notifications do not automatically remediate findings. - [Learn more](https://cellwall.io/en/solutions/alerting-incident-response) ### Third-party Script Monitoring - Review observed resources, providers and dependencies. Rule-based security scores range from 0 to 100; they are prioritization inputs, not exploitability assessments. - [Learn more](https://cellwall.io/en/solutions/third-party-monitoring) ### Notification Integrations - Configured Email, Slack, Teams and Discord delivery paths require service credentials and recipient configuration. Confirm availability before relying on catalog entries for native SIEM, Jira or deployment automation. - [Learn more](https://cellwall.io/en/solutions/integrations) ### Third-party Script Metrics - Review historical resource response times, availability, scores and issue trends, including average issue-close time where available. These measurements do not establish forecasting, MTTA or complete user-impact attribution. - [Learn more](https://cellwall.io/en/solutions/metrics-analytics) ### Bot Impersonation and Browser Evidence - Captured script and session context can support investigation. This is not a claim of bot management, CAPTCHA challenges or automated fraud prevention. - [Learn more](https://cellwall.io/en/solutions/bot-impersonation) ## 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. Browser supply-chain risk management is the process of identifying externally controlled code in the delivered website, tracing direct and indirect dependencies, evaluating meaningful runtime change, and coordinating treatment based on technical impact and business purpose. It complements vendor due diligence by showing how a service behaves in the browser. - [Learn more](https://cellwall.io/en/use-cases/browser-supply-chain-risk-management) ### Client-side attack-surface management Continuously map browser resources, dependencies, capabilities, destinations, and change; prioritize exposed edges and maintain accountable review. Client-side attack-surface management is the continuous process of discovering browser-executed resources, mapping their dependencies, capabilities, destinations, and website contexts, detecting meaningful change, and assigning accountable review. It complements external attack-surface management by covering runtime code and relationships that appear after a page reaches the visitor's browser. - [Learn more](https://cellwall.io/en/use-cases/client-side-attack-surface-management) ### 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. A consent record describes what a visitor selected. Runtime evidence shows what the website and its third parties subsequently did. Bringing those two views together gives privacy, legal, and engineering teams a practical way to review discrepancies without treating browser telemetry as a complete legal assessment. - [Learn more](https://cellwall.io/en/use-cases/gdpr-browser-data-governance) ### Incident response and containment Correlate browser-side change, scope affected sessions, apply reviewed containment, and preserve evidence for investigation and recovery. Client-side incident response is the process of validating suspicious browser behavior, identifying the responsible provider or resource, scoping affected pages and observed sessions, coordinating owners, and applying reviewed containment where supported. - [Learn more](https://cellwall.io/en/use-cases/incident-response-containment) ### 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. The code delivered to a visitor can change independently of a source repository or procurement list. A browser-focused operating process adds observed assets, supplier relationships, risk decisions, and monitoring evidence to the wider ISMS without claiming to replace it. - [Learn more](https://cellwall.io/en/use-cases/iso-27001-browser-security) ### Payment-page and 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 and digital-skimming protection is a browser-layer practice for establishing the scripts and data paths expected at checkout, observing changes to field access and network destinations, and giving teams context to investigate and contain suspicious behavior. It helps address the client-side attack path used by Magecart, web-skimming, e-skimming, and formjacking campaigns. - [Learn more](https://cellwall.io/en/use-cases/payment-page-digital-skimming-protection) ### undefined Discover payment-page scripts and dependencies in the browser, enforce deliberate boundaries, investigate unexpected changes, and retain technical evidence. SiteWall turns the browser-side portion of payment-page script governance into a live, traceable workflow. It supports specific payment-page controls, not the full PCI DSS standard. - [Learn more](https://cellwall.io/en/use-cases/payment-page-security) ### 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. 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. For PCI DSS work, it connects live browser observation, deliberate control, response workflows, and evidence while supporting specific client-side requirements—not the full standard. - [Learn more](https://cellwall.io/en/use-cases/pci-dss-payment-page-security) ### 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. Sensitive-data exfiltration prevention for websites is the practice of observing how browser code accesses supported data surfaces, mapping the destinations it contacts, and applying reviewed controls to unexpected routes. It reduces exposure in the client-side layer while complementing server, endpoint, identity, privacy, and secure-development controls. - [Learn more](https://cellwall.io/en/use-cases/sensitive-data-exfiltration-prevention) ### Third-party performance and reliability Review third-party resource load, execution, errors, observed successful-response rates, and dependency signals with browser-side provider context. Third-party performance and reliability monitoring observes external browser resources, their response and execution timing, errors, successful-response rates in captured traffic, and appearance in captured website sessions. It helps teams investigate a change in its provider and dependency context while working alongside real user monitoring, synthetic testing, application performance monitoring, and vendor service management. - [Learn more](https://cellwall.io/en/use-cases/third-party-performance-reliability) ### 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. Third-party script governance is the operating process for discovering external code in the browser, understanding what it loads, accesses, and transmits, deciding which behavior is permitted, and keeping the current decision and supporting context reviewable. It turns a changing website supply chain into a managed system of providers, resources, policies, and evidence. - [Learn more](https://cellwall.io/en/use-cases/third-party-script-governance) ### Website privacy and consent assurance Review captured consent decisions alongside observed browser behavior, investigate possible tracking discrepancies, and use the resulting technical context in privacy reviews. Website privacy and consent assurance is the technical practice of reviewing a captured visitor choice alongside the browser behavior observed afterward. Consent events, identifiers, resources, capabilities, and destinations provide context that teams can use to investigate whether the delivered experience matches the expected configuration. - [Learn more](https://cellwall.io/en/use-cases/website-privacy-consent-assurance) ## Product Comparisons The following pages use current first-party competitor sources, show a verification date, and distinguish confirmed facts from evaluation guidance: - [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) ## Technical 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. - [Security Database](https://cellwall.io/en/resources/database) - [Technical Blog](https://cellwall.io/en/resources/blog) - [Introducing SiteWall](https://cellwall.io/en/resources/blog/introducing-sitewall-browser-security): A product overview of browser resource discovery, granular policy controls, existing-workflow integrations, and evidence mapped to GDPR, ISO/IEC 27001:2022, and PCI DSS v4.0.1. - [Pricing](https://cellwall.io/en/pricing) ## Contact - Website: [https://cellwall.io](https://cellwall.io) - Email: [contact@cellwall.io](mailto:contact@cellwall.io)
