The National Data Protection Authority (ANPD) has become a central player in regulating the processing of personal data in Brazil, and understanding how it operates is essential to any due diligence strategy.

The ANPD’s Role in the Data Protection Ecosystem

When you look at the Brazilian regulatory landscape for personal data protection, the creation of the National Data Protection Authority stands out as a decisive institutional milestone. The ANPD was established by Law No. 13.709/2018 (the General Personal Data Protection Law, known as the LGPD) and structured by Decree No. 10.474/2020. Its mission is to safeguard personal data, oversee compliance with the law, and impose administrative sanctions for improper data processing.

The ANPD does not act alone. Its authority overlaps with that of other bodies, such as the Public Prosecutor’s Office, the state Procons (consumer protection agencies), and the Brazilian Internet Steering Committee. This coordination among institutions is essential if data protection is to work in practice, avoiding gaps in oversight and conflicts over jurisdiction. Article 55-J of the LGPD itself sets out an extensive list of duties for the Authority, ranging from drafting guidelines for the National Data Protection Policy to conducting audits of personal data processing.

From a data due diligence standpoint, any organization that collects, stores, or processes personal data in Brazil needs to follow closely the resolutions, technical notes, and guidance documents the ANPD publishes. These documents do not always have direct binding force, but they shape how the law is interpreted and signal the standards the Authority will apply in any enforcement proceeding. Ignoring them means operating blind in an increasingly demanding regulatory environment.

Regulatory Activity: Resolutions and Guidance Documents

The ANPD has been building its regulatory framework step by step. Among the most important measures is Resolution CD/ANPD No. 2/2022, which approved the Regulation on Applying the LGPD to Small-Scale Processing Agents. The resolution brought significant flexibility for microenterprises, small businesses, and startups, recognizing that regulatory compliance should be proportionate to each organization’s economic capacity and the volume of data it handles.

Another important regulation is Resolution CD/ANPD No. 4/2023, which approved the Regulation on Penalty Calculation and the Application of Administrative Sanctions. It sets the criteria and parameters for imposing the fines and other penalties provided for in the LGPD, including aggravating and mitigating factors. For anyone conducting due diligence, this document is indispensable, because it makes it possible to estimate the financial risk tied to potential irregularities in data processing.

The ANPD has also published guidance documents on topics such as personal data processing by public authorities, cookies and trackers, personal data protection impact assessments, and the definitions of processing agents. These guides work as an interpretive map of the law. They do not replace case-specific legal analysis, but they offer concrete parameters for building compliance programs and assessing risk in corporate transactions, technology contracts, and commercial partnerships that involve data sharing.

Keeping up with the ANPD is not just a matter of legal compliance. It is a risk management strategy that can make or break business transactions involving personal data.

The ANPD has also taken positions on emerging issues, such as artificial intelligence and the processing of children’s and teenagers’ data. These statements point to where regulation is likely headed in the coming years, and they allow organizations to get ahead of future requirements by building safeguards in from the design stage of new products and services.

Administrative Precedents and Sanctioning Proceedings

In its enforcement work, the ANPD has taken a gradual approach, putting guidance and awareness ahead of harsher sanctions. That does not mean it lacks rigor. The ANPD has already opened a number of administrative sanctioning proceedings and imposed penalties ranging from warnings to monetary fines.

Among the cases that have drawn attention in the legal community, the ANPD has turned its focus to both the public and private sectors. Government agencies have been notified and investigated for inadequate data processing practices, showing that the Authority draws no distinction between public and private actors when it comes to protecting the rights of data subjects. Companies of various sizes and industries have also been targeted by proceedings, which underscores the need for robust compliance programs regardless of the sector.

Studying these administrative precedents is especially valuable for professionals who work in data due diligence. Each ANPD decision shows how the Authority interprets core LGPD concepts, such as legal basis for processing, purpose, necessity, transparency, and security. These precedents serve as interpretive benchmarks that let you assess more precisely how compliant an organization is and what risks may stem from weaknesses in its data processing practices.

The ANPD has also made use of tools such as the Conduct Adjustment Agreement (TAC) and preventive measures, which allow irregularities to be corrected without immediately imposing fines. This procedural flexibility is a positive feature of the Authority’s approach, since it encourages voluntary compliance and lowers the regulatory cost for organizations that show good faith and a willingness to fix their practices.

Data Due Diligence: Practical Implications

When we conduct due diligence involving personal data, we treat the ANPD’s activity as a decisive factor in assessing risk. In a merger, acquisition, or investment, for example, several elements bear directly on the valuation of the deal and the drafting of protective contract clauses: any pending administrative proceedings before the ANPD, the history of security incidents reported to the Authority, and how closely the target organization follows current regulatory standards.

An effective data due diligence program should include, at a minimum, the following: verifying that a record of processing operations exists (as required by Article 37 of the LGPD); reviewing the legal bases used for each category of processing; evaluating contracts with data processors and subprocessors; confirming that a data protection officer (DPO) has been appointed; and reviewing the history of responses to data subject requests and of incident notifications to the ANPD.

Organizations that maintain a proactive relationship with the ANPD tend to show a higher level of regulatory maturity. They take part in the public consultations, calls for input, and public hearings the Authority holds. This engagement shows not only knowledge of the law but also an institutional commitment to data protection, which is a meaningful indicator in any evaluation.

It is also worth noting that the ANPD has entered into technical cooperation agreements with data protection authorities in other countries and with international organizations. This international dimension matters especially for due diligence involving international data transfers, a subject governed by Articles 33 to 36 of the LGPD that calls for extra attention in a globalized environment.

Outlook and Institutional Evolution

The ANPD’s institutional transformation deserves close attention. It has gone from being an agency linked to the Presidency of the Republic to a special-status federal agency with greater technical and decision-making autonomy. This change, made effective by Law No. 14.460/2022, strengthened the Authority’s independence and signaled the maturing of Brazil’s data protection regulatory model.

We expect enforcement to intensify in the coming years as the ANPD consolidates its organizational structure, expands its staff, and builds institutional experience. The growing number of complaints and petitions from data subjects received by the Authority supports that expectation and underscores the importance of keeping compliance programs current and effective.

Lawyers, compliance managers, and information technology professionals should systematically track the ANPD’s regulatory agenda, including ongoing public consultations, calls for input, and technical studies in preparation. This kind of regulatory monitoring lets you anticipate rule changes, adjust internal processes in time, and ultimately turn LGPD compliance into a competitive advantage.

In short, despite its youth as an institution, the ANPD has already produced a significant body of rules, guidance, and precedents that directly affect legal and business practice related to personal data processing. For anyone working in data due diligence, following this output is not optional. It is a requirement for responsible, technically sound work.
