How Family Offices Can Strengthen Their Cybersecurity
An email from a familiar vendor, an unpaid invoice, a link to pay...it seemed perfectly innocent until an unsuspecting click led to locked servers and frantic calls to lawyers and data recovery specialists for our client, a sophisticated family office. Unfortunately, they are far from the only ones.
As family offices adopt AI, rely on more third-party providers, and manage increasingly complex financial operations, they have become more attractive targets for cybercriminals—putting sensitive financial information, family privacy, and business continuity at greater risk. In our experience, the greatest cyber risks facing family offices are rarely the result of a single technology failure. More often, they emerge where people, processes, third-party relationships, and insurance fail to keep pace with an increasingly complex operating environment.
To help strengthen your family office's cybersecurity, we recommend the following best practices:
Best practices we recommend to all clients as the landscape continues to shift:
1. Identify your family office's biggest cybersecurity vulnerabilities
The trusted relationships that allow family offices to operate efficiently and discreetly can also create opportunities for cybercriminals. Many successful attacks begin with a trusted email, vendor, or financial transaction. Some of the most common vulnerabilities include:
• Phishing and social engineering: Fraudulent emails and text messages have become increasingly convincing, often impersonating trusted contacts with only subtle differences in an email address or domain.
• Ransomware: Family offices are attractive targets for attackers seeking financial records, private holdings information, and personal family data.
• Vendor compromise: Family offices often rely on outside investment managers, accounting firms, legal advisors, and technology providers. A security lapse anywhere within that network can expose confidential information.
• Deepfakes and voice cloning: AI can replicate voices and create realistic videos, making fraudulent payment requests increasingly convincing.
• AI-related data risks: Feeding sensitive financial and personal data into open AI models can expose organizations to privacy concerns and data poisoning.
2. Strengthen your cybersecurity defense
Strong cybersecurity isn't built around a single tool or software platform. It comes from layering practical controls that reduce opportunities for human error, unauthorized access, and third-party risk.
• Ensure everyone has access only to systems and information they need.
• Institute callback requirements for wires and second-channel confirmations for instructions.
• Enable multi-factor authentication for banking and investment accounts.
• Require third-party vendors to provide compliance reports (SOC 2, ISO 27001, etc) before sharing sensitive data.
• Perform penetration testing, annual risk assessments, and tabletop exercises.
3. Protect every connected device and family member
For family offices, the cybersecurity perimeter often extends well beyond the office itself—to residences, personal devices, family members, and more. Periodic discussions about the threat landscape and safety protocols help reinforce that even seemingly innocuous behaviors can cause issues. Even a child using a parent's phone could unintentionally trigger a costly incident.
4. Develop a cyber incident response plan before you need it
The worst response is a delayed one. Threat actors move quickly once inside a network. Establish an incident response plan that outlines what to do, in what order, and who to contact—broker, carrier, legal counsel—as soon as an incident is detected.
5. Review your cyber insurance coverage regularly
Cyber insurance should be viewed as one component of a broader cybersecurity strategy, not a substitute for strong controls. As family offices adopt new technologies, engage additional vendors, and conduct complex financial transactions, insurance should evolve alongside those changes.
Sophisticated cyber insurance programs have two primary components:
• Third-party coverage addresses regulatory liability, defense costs, and breach response.
• First-party coverage helps cover direct costs from a cyber incident, including forensic investigations, cyber extortion, and data and asset recovery. Family offices should also consider a Fidelity Bond (crime bond) for fraud involving social engineering or fraudulent funds transfers. Together, these coverages can help reduce gaps in protection.
“Effective cybersecurity is no longer just an IT responsibility—it's a business risk management priority.” Regular reviews can help ensure both remain aligned with today's changing threat landscape.
