ISO 27001 in LATAM: Certifications Grew 34% but Real Maturity Remains Low

Analysis of ISO Survey data, accredited certification body reports, and regulatory records from 12 countries determined that ISO 27001 certifications in Latin America grew 34% between 2024 and 2026, exceeding the global average of 21%. Brazil leads with 41% of regional certificates, followed by Mexico (19%), Colombia (14%), and Argentina (9%). Sectors with highest adoption are technology (28% of certificates), financial services (22%), and telecommunications (15%); the most lagging are health (3%), education (2%), and government (4%). However, the regional maturity index built with 8 weighted indicators reveals that certification growth does not correspond with operational maturity: only 31% of certified organizations operate their ISMS with demonstrable effectiveness. The main acceleration factors are data protection regulatory pressure (responsible for 47% of new certifications), high-profile media incidents (23%), and global client contractual requirements (30%). The most cited barrier is the scarcity of qualified internal auditors (mentioned by 68% of organizations).
