Validate consumer opt-out compliance
40% of trackers ignore consumer opt-outs, according to Ketch research across 134 major websites. See exactly which ones keep firing on your properties after a person says no, across web, mobile, and CTV.
Data Sentry is your website's privacy pentest. Reveal privacy vulnerabilities before regulators or plaintiffs' attorneys find them.

A consent signal only counts if every vendor downstream honors it. Follow GPC and IAB signals through your entire adtech chain and catch the vendors that drop them.

See what regulators will see
The CCPA amendments that took effect January 1, 2026 added risk assessments for high-risk processing, cybersecurity audits, and rules for automated decision-making technology.
Every one of those obligations assumes the business already knows what personal data it holds, which systems process it, and for what purpose.
A data map built last year describes a website that no longer exists. Data Sentry monitors what's actually running on your properties, so every assessment, audit, and disclosure starts from reality instead of a stale inventory.
Caught before enforcement
Data Sentry runs three continuous checks against the live traffic leaving your properties, the same evidence regulators and plaintiffs' firms collect when they investigate.
Identify exactly which trackers or tags continue firing after consumers opt out, flagging unauthorized data collection such as data still being sent to third-party advertising platforms or social networks.
Confirm that consent signals are properly propagated throughout the entire adtech chain, flagging vendors that fail to respect consumer consent preferences.
Analyze network traffic to reveal precisely what data you are collecting and where it is being shared with third parties, including sensitive data that shouldn't be transferred.
From packets to prioritized remediation
From packet-level detection to a fix you can act on automatically.

Coverage

Unlike niche products like cookie scanning and code scanning, Data Sentry is real time, comprehensive inspection of all traffic.

Analyze real-time data flows across web, mobile apps, and CTV environments, or ingest the same HAR files plaintiffs' firms use to build claims, ensuring no blind spots.

Data Sentry works alongside any CMP, providing an independent validation of your configuration.
Scanning coverage
Iris, the patent-pending scanning algorithm from Ketch, treats scanning as an intelligence problem instead of a volume problem.
Iris groups pages by the specific set of cookies, storage entries, and network calls they fire, not by their URL. Rare trackers concentrate in distinct site sections, like a help center or a storefront, and cohort-based scanning reliably finds them where random page sampling has to get lucky.
Data Sentry reads cookies across origins directly rather than only detecting that a request occurred. Page-embedded telemetry scripts can't read cookies set under another company's domain, so they miss the third-party cookies that matter most for a disclosure.
Every scan cycle alternates between confirming known trackers and discovering new territory, so coverage builds from cycle to cycle instead of resetting to a random sample each run.
Regulators now expect a full, regularly refreshed inventory of the tracking technologies actually running on your properties.
The Tractor Supply order from the CPPA (September 2025, retail sector) requires quarterly scans and a current inventory of every tracking technology in use.
Most scanning tools cap page counts and fill the gap with a fixed or random sample, which is why scan results shift from run to run.
Connected Discovery
A finding that stays in Data Sentry changes nothing. Ketch routes results into consent, risk, and legal response.
Integrations
Ketch ships connectors and SDKs so consent, rights, and policy flow into your CDPs, warehouses, ad platforms, and AI stack — without a custom data pipeline.
