Brazil LGPD Compliance
Brazil's LGPD requires processing agents to protect personal data with security measures.
Learn how ImmuniWeb helps you meet its Article 46 security obligation.
What Is Brazil's LGPD?
The LGPD governs how organizations process the personal data of individuals in Brazil. It sets out legal bases for processing, grants data subjects extensive rights, requires a Data Protection Officer (encarregado), and obliges processing agents to protect personal data and report breaches.
It applies to any processing of personal data carried out in Brazil, or where the data was collected in Brazil, or where the purpose is to offer goods or services to people in Brazil - giving it broad, extraterritorial reach. The ANPD enforces the law and issues regulations and guidance.

Who Must Comply with LGPD?
The LGPD applies broadly:
- Controllers and processors (processing agents) handling personal data in Brazil.
- Organizations outside Brazil that process data collected in Brazil or offer goods/services to people in Brazil.
- Any sector and size - public and private.
Any organization running web and mobile applications that process personal data must secure and test them under Article 46.
Key LGPD Requirements for Application Security
- Article 46 - Security measures: processing agents must adopt technical and administrative security measures to protect personal data from unauthorised access and accidental or unlawful destruction, loss, alteration, communication or dissemination.
- Article 6(VII) - Security principle: use technical and administrative measures to protect personal data throughout processing.
- Article 48 - Breach notification: notify the ANPD and affected data subjects of security incidents that may cause risk or harm.
LGPD Security Requirements in Depth
Article 46 - Security Measures
Article 46 requires processing agents to adopt technical measures to protect personal data. For internet-facing systems, that means securing and regularly testing the web and mobile applications and APIs that process personal data, and remediating the vulnerabilities found - before and after significant changes.
Article 48 - Breach Notification
Processing agents must notify the ANPD and affected data subjects of security incidents that may create relevant risk or harm. Reducing breach likelihood through regular application testing is the most effective way to avoid triggering this obligation.
Common Web & Mobile Application Risks to Address
Personal-data breaches frequently start with vulnerable web and mobile applications. The risks Article 46 expects you to address map closely to the OWASP Top 10:
- Broken Access Control — users reaching data or actions they should not.
- Cryptographic Failures — weak or missing encryption exposing sensitive data.
- Injection — SQL, command or other injection via unvalidated input.
- Insecure Design — missing security controls by design, not just by bug.
- Security Misconfiguration — default, incomplete or unsafe configuration.
- Vulnerable & Outdated Components — unpatched libraries and frameworks.
- Identification & Authentication Failures — weak login, session or credential handling.
- Software & Data Integrity Failures — untrusted updates, insecure CI/CD pipelines.
- Security Logging & Monitoring Failures — attacks going undetected.
- Server-Side Request Forgery (SSRF) — the server tricked into making malicious requests. For mobile apps, the OWASP Mobile Top 10 is the equivalent reference (insecure data storage, insecure communication, weak cryptography, and so on). Reliably finding these issues requires testing the running application, not just a documentation review.
How to Approach LGPD Application Security with ImmuniWeb
- Map your exposure Inventory internet-facing apps and assets with ImmuniWeb Discovery.
- Test web applications with On-Demand (penetration testing) and Neuron (scanning).
- Test mobile applications with MobileSuite and Neuron Mobile.
- Remediate and retest with actionable reports evidencing Article 46 measures.
- Keep testing continuously with Continuous in CI/CD and periodic re-testing.
- Monitor for leaks with Discovery dark-web monitoring for breach readiness.
How ImmuniWeb Helps You Achieve LGPD Compliance
ImmuniWeb helps processing agents implement and evidence the technical security measures Article 46 requires.
| Requirement | What it requires | ImmuniWeb products |
|---|---|---|
| Article 46 | Technical measures to protect personal data. | On-Demand, Neuron, Discovery, Continuous |
| Apps & data | Secure web/mobile apps and APIs holding personal information. | On-Demand, Neuron, MobileSuite, Neuron Mobile |
| Breach readiness (Art 48) | Detect exposure and leaked data to reduce eligible breaches. | Discovery (ASM / Dark Web) |
ImmuniWeb On-Demand and MobileSuite deliver web and mobile penetration testing; Neuron and Neuron Mobile provide automated scanning; Continuous embeds testing into CI/CD; and Discovery maps your external attack surface and monitors the dark web for leaked personal data.
LGPD vs International Frameworks
If you already work to international standards, the same ImmuniWeb testing supports all of them:
| Framework | Application-security angle | How ImmuniWeb maps |
|---|---|---|
| Brazil LGPD | Article 46 security measures | Web/mobile pentest, scanning, ASM, dark-web monitoring |
| Mexico LFPDPPP | Security measures for personal data | Same testing supports both |
| EU GDPR | Article 32 security of processing | Same testing supports both |
| ISO/IEC 27001 | Annex A technical controls | Testing as control evidence |
Penetration Testing vs Security Scanning
Both are needed. Automated scanning (DAST) gives broad, frequent coverage and is ideal for continuous testing in CI/CD; manual penetration testing finds business-logic and complex vulnerabilities that scanners miss and produces the depth auditors and regulators expect. Combine continuous scanning with periodic manual penetration testing, and re-test after significant changes.
Compliance Checklist (Application Security)
- Inventory of internet-facing apps and exposed assets
- Web applications tested against the OWASP Top 10
- Mobile applications tested against the OWASP Mobile Top 10
- Technical and administrative security measures implemented (Art 46)
- Findings remediated and re-tested; records retained
- Breach-notification process aligned with ANPD (Art 48)
- Exposure / dark-web monitoring in place
Why LGPD Compliance Matters
The ANPD can impose fines of up to 2% of an organization's revenue in Brazil, capped at R$50 million per infraction, alongside breach-notification duties, and its enforcement activity has been growing. A breach also brings reputational harm in Latin America's largest market.
Because web and mobile applications are a leading breach vector, demonstrably securing and testing them is one of the clearest ways to satisfy Article 46 and reduce risk.
