Cybersecurity and Data Privacy in Family Offices
UHNW families are a high-yield target for sophisticated attackers, and the office is usually the weakest link in the family's overall security posture.
Key takeaways
- —MFA, password managers, and endpoint protection are table stakes.
- —Email is still the primary attack vector — train against pretexting, not just phishing.
- —Travel and personal-device policies need explicit family adoption.
- —Annual penetration testing by a firm specialising in family offices catches what generic firms miss.
Family offices face a threat model that does not fit standard enterprise security. The attacker profile is small, well-funded, motivated, and patient. They will not run mass phishing; they will research the family for months and craft pretexts targeting specific assistants, lawyers, or principals. They will exploit travel patterns, social media, and the office's external service providers. Generic enterprise security tooling is necessary but rarely sufficient against this profile.
Working security combines tooling with practice. Multi-factor authentication, password managers, endpoint detection, and encrypted email are baseline. Above the baseline, the work is human: training that focuses on pretexting (not just generic phishing), explicit policies for travel and personal devices, segmentation of the family's broader ecosystem (lawyers, accountants, estate-managers) so a compromise in one does not cascade. Annual penetration testing by a firm that specialises in family offices catches the issues that generic auditors miss.
