GDPR and Compliance

Netvigie Tracking is a powerful ally to help you verify that your implementation respects the GDPR and data privacy rules.

Alert on personal data collection by a third party​

  • Objective: Ensure that personal data (email, name, IP, etc.) are not sent to third-party partners without authorization.
  • Functioning:
    1. Mark sensitive data: When creating a collector that retrieves personal data (e.g. a CSS collector for the email field in a form), check the "Sensitive data" box.
    2. Detection: During a crawl, if Netvigie Tracking detects the value returned by this collector in the parameters of a third-party tag, a "Sensitive data" type alert will be generated.
    3. Exception management: It is sometimes legitimate to send data (like a client ID) to a partner (like your analytics solution). In Tags > Sensitive data > Exception management, you can create a rule to authorize a specific collector to be sent to a specific tag, which will disable the alert for this specific case.

Alert on user consent non-compliance​

  • Objective: Verify that tags requiring consent only fire when the user has given their agreement via your cookie banner (CMP).
  • Configuration:
    1. Create a collector that reads the consent state (usually a Cookie type collector that reads the cookie placed by your CMP). The value of this cookie indicates which partners are authorized.
    2. Go to Tags > Tag Management and edit the tag you want to verify (e.g. "Criteo").
    3. In the "Consent" box, add a consent constraint.
    4. The constraint will use your cookie collector. Example of rule: {{Consent Cookie}} must contain criteo.
    5. This means that the Criteo tag will only be considered legitimate if the value criteo is present in the consent cookie.
  • Verification:
    • Create a "Cookie Refusal" Crawl Mode that uses a preparatory scenario to refuse consent on your CMP.
    • Launch a crawl with this mode. If the Criteo tag is detected, Netvigie Tracking will verify the consent constraint. As it will not be satisfied, a "Non-consented tag" alert will be raised.

Blacklisting a tag​

  • Objective: Declare that a tag must never be present on your site (or on a specific context).
  • How?
    1. Go to Tags > Tagging Plan.
    2. In the table, on the row of the tag to ban and the column of the desired context (or "All contexts"), click on the + to add a rule.
    3. Click on the ... and select "Forbid this tag".
    4. Save.
  • If the tag is detected during a future crawl, its score will drop to 0 and an alert will be generated.
