What this actually means
2 requests in this visit matched Brave Shields filter lists.
2 requests matched while loading normally. This run records no evaluated-request count, so no match ratio is stated. Matching identifies traffic the lists would target; it does not establish the purpose or payload of an individual request.
The scan observed signals a non-expert should not have to decode from raw request tables.
The cards below translate the evidence into plain language; severity reflects fixed reference thresholds, not measured population percentiles. The request log, domain table, and methodology remain below for verification.
64 requests observed in one controlled visit.
Context
2 requests matched Brave Shields filter lists
2 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.
Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.
The hand-curated service catalog separately matched 0 request rows in this visit.Show matched requests
Low signal
No change observed in the Brave-list blocking attempt
The blocking visit (the scanner configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit; application was not verified)) showed no change in the comparable metrics (third-party requests, third-party cookies and tracking-related service requests).
The blocking visit's engine directly blocked 2 requests; ad rotation, experiments, or caching between the two visits can offset or outweigh what blocking removed, which is how totals can hold steady or rise despite direct blocks. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as no observed difference for this pair of visits, not evidence that blocking removes nothing.
Signed per-metric differences between the two visits; nothing is summed across metrics.Show matched requests
Worth checking
1 first-party DNS alias matched tracking checks
1 resolved target matched Brave filter lists; those matches do not identify the operators.
The scanner followed DNS CNAME chains from first-party subdomains and checked resolved targets against the service catalog and Brave filter lists. These matches do not establish a request's purpose, profiling, or an intent to conceal tracking. A filter-list match alone is not a verified service identity or proof of tracking.
Privacy policy read; it made no statement this scan can check
None of the statements this scan knows how to check appear in the policy text, so nothing was compared against this visit's evidence (no catalogued tracking companies observed to check against it). That is a limit of the automated check, not a finding about the site either way.
Statements checked automatically: blanket no-cookie claims, third-party-cookie claims, and combined do-not-sell-or-share claims against advertising-pixel identifier fields. Global Privacy Control claims are never checked against request counts, which cannot show whether selling or sharing stopped.
Policy at https://{label}.europa.eu/{seg}; 0 checkable statements matched; no catalogued tracking companies observed to check against it.
Nothing observed
No known services matched
This scan did not match any third-party domains to the service catalog or another identity source.
The automated visit did not observe third-party cookies.
This does not prove the site never uses cookies; it means this visit did not observe third-party cookies.
3 cookies total in this report.No third-party cookies observed.
Nothing observed
No fingerprint-like API calls observed
The scan did not observe the instrumented high-entropy browser APIs.
This is an observation layer, not proof that fingerprinting is impossible.
0 API families recorded.
Brave Shields Comparison
No blocking → Brave-list blocking delta
No blocking: 8,754msBrave-list blocking: 7,639ms
Some deltas are not comparable across these two visits and are not shown.
Other detector and causal-path deltas (each visit's own evidence still renders below): v1 never recorded detector versions, so fingerprinting and pixel deltas cannot be proven to come from matching instrumentation.
The Shields-number delta (each visit's own evidence still renders below): The two visits measured different Shields quantities (filter-list matches vs engine-blocked requests), which must never share a delta.
Fingerprinting deltas (each visit's own evidence still renders below): At least one visit did not complete the fingerprint measurement, so no exact cross-visit delta is shown.
Ad-pixel deltas (each visit's own evidence still renders below): At least one visit did not complete the pixel measurement, so no exact cross-visit delta is shown.
Every signed change is Brave-list blocking minus No blocking. A positive or negative direction is descriptive, not a judgment that the result is better or worse.
Cookie and storage count deltas include every observation. Name-level lists show only reviewed names; unreviewed names are not itemized because they can contain identifiers.

Measurement limits
8 conditions affect how this evidence reads
This report
Brave-list blocking comparison runs should be collected under matched crawl conditions, and the blocking run is a simulation with Brave's engine and default lists in this scanner's browser, not a live Brave visit. Differences can still reflect timing, experiments, cache state, consent state, or bot detection.
The two visits ran in randomized order; the "Brave-list blocking" visit ran first.
Both visits
Each visit in this report is one automated, headless Chromium visit from a fixed en-US / UTC profile, with no scrolling, clicking, or consent interaction. Sites can behave differently for real users, browsers, regions, accounts, or network locations.
Counts are a lower bound: trackers that load only after interaction or consent are not observed; Service Workers are blocked, and Web Worker or WebSocket traffic may be incomplete. Service labels use a US-biased hand-curated catalog, so regional services may be under-labeled. Cookie and storage figures are an end-of-visit snapshot, with storage keys read from the top frame only.
This scan typed a synthetic test value into 1 form field with native form submission blocked. Focus, input and blur handlers may run and send requests. The value is synthetic and is not stored. Observed requests during typing and the following wait are included in the request log. Teardown-only transmissions are not measured.
Read the site's privacy policy (https://{label}.europa.eu/{seg}) and compared its text against this visit's observed behavior. Policy checks are an automated text match with the matched sentences quoted, not a legal reading.
No blocking visit only
Resolved 1 first-party subdomain that is a CNAME alias for a third-party tracker (CNAME cloaking), which request-URL matching alone would miss.
Brave-list blocking visit only
Brave Shields block simulation was enabled; matching requests were aborted before loading and are not included in request totals.
How to use this report
Read the findings and measurement limits first, then inspect the evidence for each recorded visit. Comparisons include both visits, even where a difference cannot be interpreted.
Keep this PDF with its evidence package: the source JSON, correction context, export receipt and SHA256SUMS. The package preserves source bytes and the correction context at export time. Hashes check file consistency; they do not establish independent measurement accuracy or a signed attestation.

Provenance
Exact build and instrument digests were not recorded by this legacy schema.
Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.
This report covers what the scanner measures, not everything a site can do. 17 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 14 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.
Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.
Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on .
Reports record one automated visit per condition; visits may be incomplete. On restart-safe deployments, an interrupted visit may be retried; attempts are never merged. Results describe these visits, not everything a site can do.
