Family offices manage significant wealth with small teams and light IT infrastructure, which makes them attractive — and often under-protected — targets. The good news is that the highest-impact security measures are practical, inexpensive, and something a lean team can put in place quickly. This guide covers four practical measures that are easy to implement and often high-value: password management, emergency access, multi-factor authentication, and phishing training, plus where formal compliance tools fit in.
These are practical tips your team can implement today, small changes that can have a big impact on reducing risk, though not a substitute for dedicated in-house cybersecurity expertise as a family office grows.
Why are family offices a target for cyberattacks?
Family offices sit at an unusual intersection: they authorize large wire transfers and hold sensitive personal and financial data, but they typically run with a handful of staff and none of the security apparatus a bank or large corporation has. Attackers know this. A single compromised inbox or reused password can be enough to redirect a payment or expose an entire family's financial picture. Most incidents aren't sophisticated hacks — they're a convincing email or a weak credential.
The data bears this out. Deloitte's 2024 Family Office Cybersecurity Report found that 43% of family offices worldwide had experienced a cyberattack in the prior 12–24 months — rising to 57% in North America and 62% at offices managing more than $1 billion — with 25% hit three or more times. Phishing was the most common method by a wide margin, affecting 93% of victims. Yet roughly a third of family offices still operate without a cyber incident response plan.
What is the best way to manage passwords in a family office?
Get everyone onto a dedicated password manager. 1Password and Bitwarden are both strong choices. Beyond generating strong, unique passwords, the real win for a small team is shared vaults: you can store shared logins and admin credentials in one controlled place, decide exactly who can see what, and retire the spreadsheet-and-sticky-note habit that quietly creates most of the risk.
How should a family office plan for emergency access?
Continuity matters when a key person is unreachable or incapacitated. The two leading tools handle this differently:
- Bitwarden has a built-in emergency access feature. You designate a trusted contact and set a wait period; if something happens to you, they can request access, which you approve manually or which grants automatically after the wait. You choose whether they get view-only or full takeover access.
- 1Password doesn't offer that automatic trigger. Instead, an account administrator can recover another member's account, and each person keeps an "Emergency Kit" (a document containing their Secret Key) stored somewhere secure like a safe.
Both approaches work. If automatic, hands-off emergency access is a priority, Bitwarden handles it more directly out of the box.
What kind of multi-factor authentication should family offices use?
Turn on multi-factor authentication (MFA) everywhere it's offered — email, banking, custodial portals, and your password manager itself. It is one of the highest-return controls available: Microsoft reports that MFA blocks over 99% of automated account-compromise attacks. Not all MFA is equal, though: use an authenticator app (such as Google Authenticator) or, better still, a hardware key (such as a YubiKey). Avoid SMS text codes where you can, since they are the easiest factor for an attacker to intercept or socially engineer.
How can family offices prevent phishing attacks?
Phishing is where the real exposure lives. A well-crafted email that gets a staff member to click a link or hand over a login code is far more common than any exotic technical breach. Verizon's 2025 Data Breach Investigations Report found that the human element - phishing, social engineering, and misuse - factored into 60% of breaches, with stolen credentials and phishing among the leading initial-access vectors. The single most effective defense is ongoing training. Tools like Hoxhunt send simulated phishing emails and coach your team over time, building the instinct to pause and verify. This kind of continuous, hands-on practice moves the needle far more than a one-off security briefing.
Do family offices need security compliance software?
Platforms like Drata and Vanta are built primarily for larger companies pursuing formal certifications such as SOC 2, so full deployment is usually overkill for a family office. That said, they offer well-built templates for security policies, and lighter tiers may be worth exploring if you want a documented, repeatable framework rather than an ad hoc set of rules.
The bottom line
You don't need an enterprise security budget to protect a family office — you need a small set of disciplined habits: a shared password manager, a clear emergency access plan, strong MFA, and a team trained to spot phishing. Put those four in place and you've closed off the overwhelming majority of realistic threats. Be wary of specialists who lead with fear rather than value; the practical steps above will get you most of the way there.
At MyFO, security is part of how we think about running a family office day to day — the same operational discipline that keeps entities, reporting, and cash flows organized applies to the systems and credentials that sit underneath them.
Frequently asked questions
What is the biggest cybersecurity risk for a family office? Phishing, a convincing email that tricks a staff member into clicking a link or sharing a login code, is a far more common cause of incidents than any technical breach.
Which password manager is best for a family office? Both 1Password and Bitwarden work well. Bitwarden offers built-in emergency access, while 1Password relies on administrator recovery and securely stored Emergency Kits.
Is SMS-based two-factor authentication safe? It's better than no MFA, but authenticator apps and hardware keys are safer, because SMS codes can be intercepted or socially engineered.
Do family offices need SOC 2 compliance? Usually not, but the policy templates offered by tools like Drata and Vanta can still be useful for building a documented, repeatable security framework.
