Ricardo Esper is a Chief Information Security Officer (CISO) and international consultant with over 34 years dedicated to information security. He founded NESS in 1991, when cybersecurity was still a niche subject in Brazil, and has since built a portfolio of companies addressing different layers of the problem: forense.io (digital forensics), Trustness (privacy and compliance) and Infinity Safe (executive protection). He is currently CISO of IONIC Health, where he leads security strategy in digital health — a sector under simultaneous pressure from LGPD, HIPAA and ransomware attacks. His work spans more than 12 countries and combines governance (CCISO, GDPR and SOC 2 readiness) with hands-on technical practice (CEHv8, OSINT, TSCM). He is a member of OWASP, IAPP, HackerOne, ERII and OAB/SP, and writes regularly about threats, privacy and incident response at esper.ws.
