Brazil has become Latin America’s digital powerhouse from booming fintech in São Paulo, to e-commerce giants, to smart city initiatives across Rio de Janeiro and Brasília. But with rapid digitization comes escalating cyber risks. Brazil consistently ranks among the most targeted countries in the world for phishing, ransomware, and banking malware attacks.

With strict data protection regulations like LGPD (Lei Geral de Proteção de Dados), sectoral compliance standards for finance and healthcare, and growing reliance on cloud and SaaS ecosystems, Brazilian businesses must strengthen cybersecurity to remain resilient.

Government initiatives, CERT.br (Brazilian Computer Emergency Response Team), and private players are working together to secure critical infrastructure, protect digital transactions, and build cyber resilience.

In this landscape, leading cybersecurity companies in Brazil are driving innovation, compliance, and advanced defense.

Key Cybersecurity Trends in Brazil (2025)

• Banking & Payment Threats – As digital banking adoption grows, Brazil faces advanced fraud, phishing, and account takeover attacks. 
• Ransomware & Critical Infrastructure Risks – Energy, healthcare, and transport sectors remain top targets. 
• LGPD Compliance Pressure – Strict requirements for data protection, breach notifications, and governance demand expert support. 
• Cloud Security & SaaS Growth – Brazil’s startups and enterprises are rapidly migrating to the cloud, expanding attack surfaces. 
• AI-Powered Cybercrime – Fraudsters are leveraging AI-driven phishing and malware campaigns. 

SMB Cybersecurity Gap – Small and mid-sized businesses remain vulnerable due to limited resources and expertise.
