Isn't a corporation a richer target than a single family?

By gross assets, often yes. But a corporation spreads those assets behind layers of controls — a security team, segregated duties, audited processes. A family office concentrates comparable wealth behind a handful of trusted people and very few of those controls, which is what makes the per-attempt payoff so attractive.

We are small and private. Why would anyone find us?

Family offices are quieter than public companies, but they are not invisible. Property records, regulatory filings, press about the family's business, and the family's own social posts all leave a trail. Attackers do reconnaissance; privacy by obscurity is not a control you can rely on.

What single change reduces the risk the most?

Putting a verification step between a payment instruction and the money leaving — an out-of-band callback on every wire and every change to bank details. It is unglamorous, it is inexpensive, and it defeats the most common way money is actually lost.

Why a Family Office Is a Bigger Cyber Target Than a Corporation

The uncomfortable asymmetry

A family office is, in security terms, a strange animal: it carries the balance sheet of a sizable corporation and the staffing of a boutique. That gap — significant wealth, very few defenders — is precisely what makes it attractive to a capable attacker. A public company of comparable value runs a security team, segregates duties, and audits its own processes. A family office often moves the same money through a handful of trusted people who already wear every other hat. This is general information, not legal advice, and not a substitute for retained counsel or a tailored security assessment — but the structural point is worth sitting with before any incident forces it.

Concentration without the controls

In a corporation, a fraudulent payment usually has to cross several desks. In a family office, the same instruction can travel from an email to a wire with one or two people in the loop, often the same people who manage the calendar, the properties, and the household. The wealth is concentrated; the approvals are concentrated; the institutional memory is concentrated. Remove or deceive one person and the whole structure can be reached. Deloitte's Defining the Family Office Landscaperesearch counts roughly 8,030 single-family offices worldwide, about 3,180 of them in North America — a quiet population that collectively stewards trillions of dollars with a tiny fraction of the controls a bank applies to a comparable sum.

A team that wears every hat

The strength of a family office — small, loyal, fast — is also its exposure. There is rarely a chief information security officer, rarely a security operations center, rarely a formal change-control process for who can authorize a payment. Decisions happen on trust and speed, which is exactly the environment social-engineering attacks are built to exploit. The point is not that the team is careless; it is that the team was hired to manage a family's affairs, not to defend against a professional adversary.

The principal is, by definition, discoverable

Public companies file disclosures, but their treasury staff are anonymous. A principal is the opposite: the family name is the brand, the foundation, the building, the deal in the press. That visibility is often unavoidable and sometimes deliberate — but it hands an attacker a starting map. Knowing who the principal is, who works for them, and how the household communicates is most of the reconnaissance a convincing impersonation needs.

What the data actually shows

This is not theoretical. In Deloitte's 2024 survey of family offices, 43% reported a cyberattack in the prior 12 to 24 months, and that figure rose to 62% among offices managing more than US$1 billion. Nearly a third — 31% — had no incident-response plan at all. North America was the most-targeted region, at 57%. The most common attack form was phishing, reported by 93% of those hit — the patient, human approach, not the cinematic breach.

Where the money actually leaves

Phishing is the most common way in; a fraudulent transfer is the most common way money leaves. The FBI's Internet Crime Complaint Center logged 21,442 business-email-compromise complaints in 2024, with adjusted losses of roughly US$2.77 billion. For a family office, that is the scenario that matters most: a believable instruction, a real-looking change of bank details, and a wire that cannot be recalled. The mechanics are worth understanding in their own right — see how business email compromise targets a family and the controls that stop a fraudulent wire.

What changes the math

The asymmetry is real, but it is not fixed. The same small size that creates exposure also makes a family office quick to improve: a short list of well-chosen controls, applied consistently, closes most of the gap. Out-of-band verification on payments, least-privilege access for staff, multifactor authentication everywhere, a written and rehearsed response plan, and a deliberate reduction of the principal's public footprint do more than any single product. For the full enumeration of the risks most wealth managers overlook, the companion piece on family-office cybersecurity risks walks through each one.

A measured first step

Most engagements begin with a quiet conversation rather than an alarm. The useful question is not “are we a target” — the structure answers that — but “which two or three changes would have stopped the incidents other families in our position have already lived through.” That is a solvable problem, and a discreet one.
