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.
