This section defines scope, owner, evidence inputs, and the review outcome before execution. Brazil LGPD breach notification turns on a simple question: did a security incident create a relevant risk or damage to individuals? This page helps identify when the controller must notify the ANPD and affected data subjects, what the notice must cover, and how to document the decision. ## What should teams decide about Breach Notification under the Brazil LGPD? Under Article 48 of the LGPD, the controller must communicate a security incident to the ANPD and to the data subject when the incident may create relevant risk or damage. The practical question is not whether there was any issue at all, but whether the event crosses that notification threshold. Use the decision record to capture the incident type, affected systems and data, the risk assessment, whether the ANPD and data subjects must be notified, and the timing used for the notice. The ANPD incident form also expects the controller to record when it learned of the incident, when it notified the ANPD, and when it notified the data subjects. - Decide whether the incident may create relevant risk or damage to data subjects. - Identify who must be notified: the ANPD, the affected data subjects, or both. - Record the incident date, the date of awareness, and the dates of each notification. - Keep the facts, risk assessment, and supporting evidence together so the decision can be reviewed later.

Ownership should sit with the team that controls the processing purpose, data-subject channel, vendor relationship, transfer mechanism, security incident response, or ANPD communication. Evidence should show controller/operator mapping, lawful basis, transparency notice, rights response, transfer analysis, incident decision, DPO involvement, and ANPD remediation record where applicable. - Name one accountable owner and one reviewer for the Breach Notification workflow. - Keep source screenshots or source links, decision notes, implementation tickets, and approval records together. - Use dated evidence for deadlines, notices, risk assessments, contracts, user journeys, and regulator-facing records. - Review the evidence after product changes, new markets, new vendors, enforcement updates, or material changes in the source text.

Most LGPD mistakes happen at the boundary between controller and operator duties, consent and other lawful bases, academic or public-interest processing, international transfers, and incident notification thresholds. Apply this section before approving a processing activity, vendor arrangement, transfer, rights workflow, child-data handling, or incident response under LGPD. If evidence is missing, block progression and raise a review task. - Check whether the rule changes for minors, consumers, business users, public-sector bodies, regulated sectors, high-risk services, or cross-border transfers. - Separate binding law, regulator guidance, consultation material, standards, and enforcement commentary in the evidence record. - Do not rely on a previous answer if the data categories, user interface, vendor role, or contractual flow changed. - Track unresolved assumptions in an open-questions section and route legal interpretation points for review.

Use an LGPD workflow that captures role, purpose, lawful basis, data category, data-subject right, transfer or incident trigger, DPO review, evidence, and review date. The output should be a lawful-basis memo, role map, privacy notice update, DSAR record, transfer note, incident assessment, or ANPD response pack. - Create a short intake question that identifies the Breach Notification scenario. - Map the answer to a required action, evidence field, owner, reviewer, and review date. - Link related artifact pages with descriptive anchors so users can move from scope to deadlines, controls, penalties, and templates. - Update the workflow when official source material changes or when non-public evidence shows recurring exceptions.
