Cookie behavior before and after consent
Detects cookies visible during browser sessions and separates likely hard failures from items that need classification or owner review.

SentinelScan
Browser-based consent and tracking compliance scans for teams that need evidence about cookies, tags, requests, Consent Mode, scripts, and regional behavior.
- Real browser sessions, not static page checks
- Regional scan workers including EU and Germany
- Consent, tracking, script, header, and report evidence
SentinelScan is ModeConsent's browser-based scanner for cookie consent, Google Consent Mode, analytics tags, third-party scripts, security headers, and client-ready scan reports.
It is built for professional audit and monitoring workflows where teams need to know what a real browser loaded, stored, requested, and exposed before they rely on a consent implementation.
The scanner is not a legal conclusion engine. It is an evidence layer for the implementation questions that decide whether a CMP, GTM container, Google setup, or vendor stack needs repair.
Scan coverage
What SentinelScan checks.
Each scan turns runtime behavior into technical evidence that can guide remediation and stakeholder review.
Third-party scripts and vendor risk
Captures loaded scripts, vendor domains, categories, and regional-only exposure.
Google Consent Mode defaults and updates
Checks whether consent defaults and final updates are visible in the page state before teams rely on Google platform diagnostics.
GA4 and Google Ads request behavior
Looks for analytics and ad request evidence, including regional measurement gaps.
CMP implementation issues
Flags missing consent state, category mismatches, or runtime behavior that does not match the intended CMP setup.
Security headers, SEO, and runtime errors
Adds header grades, SEO hygiene checks, console issues, and page-state signals that affect trust and tracking.
Operational use cases
Built for teams that need validation before they rely on consent data.
- 01
Pre-launch consent QA
Validate consent behavior before new pages, CMP settings, GTM releases, or paid campaigns go live.
- 02
Post-CMP implementation validation
Confirm browser behavior after banner, category, geolocation, CMP callback, and tag sequencing changes.
- 03
Monthly monitoring for client sites
Track drift as marketing tools, analytics tags, scripts, and site templates change.
- 04
Germany and EU compliance checks
Use regional workers to inspect behavior from privacy-sensitive markets instead of assuming one region represents all visitors.
- 05
Analytics and conversion tracking recovery
Find where consent logic suppresses intended measurement, sends requests under the wrong state, or lets vendors run too early.
- 06
Vendor drift detection
Catch third-party scripts, pixels, and embedded tools that appear after the original implementation.
Report evidence
Client-ready scan reports turn browser behavior into reviewable findings.
SentinelScan reports are designed to help legal, marketing, analytics, and web teams review the same technical evidence without relying on screenshots alone.
Grades
Compliance and security grades
Reports summarize technical scan results without claiming a legal conclusion.
Consent
Consent Mode and dataLayer status
Default, update, and page-state signals are preserved when visible so implementation teams can review timing and state.
Requests
GA4, Google Ads, cookies, and scripts
Network requests, cookies, third-party scripts, and regional differences are preserved for review.
Stakeholders
Public report URL
A client-ready URL lets legal, analytics, marketing, and web teams inspect the same scan.
Technical credibility
