Evidence quality

This report is built on an incomplete visit

Incomplete evidence: evidence was cut short before completion (the synthetic form-input probe did not complete its test, so input-capture detection is incomplete). Counts for the affected evidence are lower bounds; families that completed carry only their ordinary limits. The evidence receipt states the exact per-visit quality.

What this actually means

mit.edu recorded 8 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 73 requests; the visit 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) recorded 8 fewer third-party requests. The blocker directly stopped 4 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

Worth checking

Bottom line: this visit has review-worthy signals

The scan observed signals a non-expert should not have to decode from raw request tables. Some detector evidence was incomplete; each affected detector card states its own retained or unavailable scope, while completed request, cookie, and storage measurements keep their recorded exactness.

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.

73 requests observed in one controlled visit.

Context

9 requests matched Brave Shields filter lists

9 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 9 request rows in this visit.Show matched requests

Nothing observed

Lower values observed across comparable metrics in the Brave-list blocking attempt

With 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), this paired visit showed 8 fewer third-party requests and 7 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google and Crazy Egg. The blocking visit's engine directly blocked 4 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as an observed difference, not a measured blocking rate.

Worth checking

1 first-party DNS alias matched tracking checks

Recorded DNS aliases resolve to catalogued tracking-related services: PostHog.

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.

Context

Requests were dispatched to catalogued service domains

Google, Crazy Egg and Mailchimp appeared in the request log.

A catalog match identifies a maintainer-reviewed service/domain mapping; it does not establish why an individual request occurred, what it carried, or whether profiling happened. Functional catalog labels include analytics / tag management, advertising and session replay / behavior analytics. This scan could not identify 3 of the 12 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site. Catalog labels include session-replay or behavior-analytics services: Crazy Egg; the domain match alone does not prove that a recording occurred. The role taxonomy assigns these additional services explicitly non-tracking operational, support, security, consent-management, or hosting roles: Sentry.

No third-party cookies observed

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.

Context

Session-replay vendor observed

Crazy Egg appeared in the request log.

This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain; a cross-site origin in that chain does not by itself establish that the cross-site script registered the listener, because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain, so the card says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected); treat this card as a review prompt rather than proof.

known session-replay vendor(s): Crazy Egg

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.

Brave Shields Comparison

No blocking → Brave-list blocking delta

No blocking: 4,780msBrave-list blocking: 4,583ms
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.

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.
  • The synthetic form-input probe did not complete its test, so input-capture conclusions for this visit are incomplete.
  • 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.
  • 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.

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.
