Family Office Cybersecurity: Ten Questions Every Wealth Manager Should Ask

The cybersecurity question a wealth manager needs to answer about a client is not whether the family has good security. It is a narrower and more uncomfortable one: if something happened to this principal's personal digital life tomorrow, would anyone be able to say who was responsible for preventing it? For most families the honest answer is no. The corporation has a security department, the family office has an IT provider for its own systems, and the principal's personal accounts, devices, home networks and family members sit in the gap between them — the assets with the least protection and the most exposure. The ten questions below are the ones worth asking in a review meeting. They are diagnostic rather than technical, and none of them require the person answering to be an engineer.

Why this became an advisor's question

It became an advisor's question because of where the losses land. Wire fraud against a private client is not an IT incident; it is a transfer that leaves an account, and the conversation that follows happens with the person who manages the money. The same is true of the extortion demand that arrives after a home computer is compromised, and of the identity fraud that follows a takeover of the principal's email.

Advisors are also, in practice, the ones who find out. The family will not call an engineer when something feels wrong about a payment instruction. They will call the person they already speak to about money. That makes the question of preparedness a service question, and increasingly a competitive one — a firm that has raised it before anything happens occupies a very different position afterwards than one that had never mentioned it.

None of this requires an advisor to become a security expert. It requires knowing which questions separate a family that is covered from one that merely feels covered.

The ten questions

1. Who is responsible for the principal's personal cybersecurity, by name? The most common answer is a pause, followed by a reference to the company's IT department — which has no authority over personal devices — or to a family member who is good with computers. A good answer names a person or a firm with a defined remit that explicitly includes personal accounts, personal devices, the residences and the family. Ambiguity here is the finding; everything else is detail.

2. How does the family verify a payment instruction that arrives by email or phone? Ask them to describe the actual procedure for a seven-figure transfer. A good answer involves a call-back to a number held on file — not one supplied in the message — and a second person who must independently approve. A weak answer involves recognizing the sender's writing style or voice, which is no longer a control worth relying on. This single question predicts more real financial loss than any other on the list.

3. What happens to the principal's accounts if their mobile number is taken over? Phone numbers can be moved to another SIM by someone who is not the owner, and when that happens every SMS verification code follows. The question is really about whether the family's most important accounts still depend on text messages, and whether carrier-level port locks have been set. Most families have never heard of the locks and are protected by nothing.

4. Which family members and household staff have access to what? Adult children, a spouse's assistant, an estate manager, a chief of staff, a former employee whose access was never revoked. Wealthy households accumulate access the way they accumulate property, and almost never conduct a review. A good answer is that someone maintains a list and revisits it; a common answer is that nobody has ever asked.

5. When was the family's public data exposure last reviewed? Home addresses, mobile numbers, dates of birth, family relationships and travel patterns are assembled and sold by data brokers, and they are the raw material for both impersonation and physical risk. This is one of the few areas where straightforward, repeatable work measurably reduces exposure — and where almost no family has done any.

6. Who secures the residences — including the ones they are not living in? A primary home with a well-configured network is not much comfort if the vacation property's cameras, entry system and network were installed by a contractor with a default password and never revisited. Yachts and jets frequently sit outside every inventory anyone maintains. Ask specifically about the properties nobody thinks about, and about whether the smart-home systems are on the same network as the family's computers.

7. Is there an incident plan, and does the family know who to call at eleven on a Saturday night? Incidents do not respect business hours, and the first hours are where most of the value is preserved or lost. The plan does not need to be elaborate. It needs to exist, to name a number that will be answered, and to be known to the people who would be the ones to notice — which usually includes a spouse and a household manager, not only the principal.

8. Does the family carry personal cyber insurance, and do they know what it requires of them? Coverage increasingly exists within high-net-worth policies, and it is frequently unused because nobody remembers it is there. It also carries conditions: notification windows, approved responders, evidence requirements. A family that handles an incident entirely on its own initiative can extinguish its own claim, which is a poor way to discover the policy's terms.

9. Who holds the keys — password manager, cryptocurrency, estate access? This is a continuity question as much as a security one. If the principal were unavailable tomorrow, could the family reach what they need to reach — and is the mechanism that would allow it something more considered than a document in a drawer or a spreadsheet in an inbox? Self-custodied digital assets make this urgent: keys that exist in exactly one head are an estate problem waiting to happen.

10. How would the family find out that something had gone wrong? Most compromises are quiet. Mail forwarding runs for months, a mailbox rule diverts correspondence, a compromised device sits idle until it is useful. Ask what monitoring exists across the personal estate and who receives the alert. For most families the honest answer is that they would find out when the consequence arrived, which is the point at which the options are worst.

Raising it without alarming anyone

Advisors hesitate here for a reasonable reason: the subject sounds like fear, and fear is not the register in which good advisory conversations happen. It helps to frame it the way the rest of the client's affairs are framed — as an unreviewed exposure rather than an emergency.

The most useful framing is comparative. A family holding assets equivalent to a mid-sized company's balance sheet is generally protected, on the personal side, by consumer software and habit. Institutions with far less at stake maintain security departments. That gap is not a failing of the family; it is an artifact of how private wealth is structured, and it is straightforwardly closable.

It also helps to be clear about what an engagement does not involve. Good work in this area does not require the principal to become technical, to change how they use their devices, or to hand over control of their affairs. The strongest outcome is one the family barely notices day to day.

What a partner should look like

If a family concludes that it needs help, the selection criteria matter as much for the advisor who made the introduction as for the client. Discretion should be structural rather than promised — a firm accustomed to private clients understands that the circle of people who know is itself something to be managed. The engagement should cover the household as a unit rather than a device inventory, since staff and family members are where most successful attacks actually begin. And the relationship should be one that survives contact with an incident: reachable outside business hours, able to work alongside counsel and insurers, and able to explain what happened in language the family can act on.

For an advisor, the value of asking these ten questions early is not that they produce alarming answers. It is that they produce a documented conversation — evidence that the exposure was raised, considered, and either addressed or knowingly accepted. That is a materially better position than the alternative, which is the same conversation happening for the first time on the day a transfer goes missing.
