Customer perspective
Data Protection Officer
Drammen Municipality
“StackPatrol provided clear technical insight into the third-party services on our website and helped us investigate and follow up on the findings.”
Built for accountable web teams
One evidence layer. Three ways to use it.
StackPatrol gives the people responsible for a website the same technical record, whether they need to advise, implement or oversee.
Digital & marketing agencies
01Audit client sites, turn findings into remediation work, and keep the relationship active with weekly monitoring.
Privacy consultants & DPO teams
02Bring technical evidence into legal review: what loaded in each consent state, which disclosures matched, and what changed after a fix.
Multi-site organisations
03Prioritise changes across brands and domains from one dashboard, with dated evidence and alerts for sites that need attention.
How it works
From URL to reviewable evidence.
The free scan stays intentionally simple. Deeper consent tests and monitoring build on the same report.

Review the evidence
See matched vendors, ownership regions, requests and the next questions worth investigating.
Inside the report
Four questions, answered with evidence.
The free report maps the visible stack. Consent Assurance adds controlled browser states, disclosure checks and evidence that can be reviewed with a client or DPO.
