Cyber security for Australian family offices.
Family offices are high-value targets. Most have security postures that do not reflect that. IronSights helps Australian family offices protect concentrated wealth, beneficial ownership data and the privacy of the families they serve, without undermining the discretion those families expect.

Threat context
Why family offices are attractive targets.
A family office manages concentrated wealth across multiple entities, trusts, companies, superannuation funds, investment vehicles, with a small team and a low public profile. That combination is precisely what sophisticated attackers look for. The assets are substantial. The operational security is often thin. The same privacy that characterises good family office practice can mean gaps go undetected for months or years.
BEC campaigns targeting large wire transfers and investment instructions are the most direct threat. Attackers who research a family office understand the ownership structures, the key advisers, the communication patterns and the transaction frequencies before they act. A convincing email arriving at the right moment, from what appears to be a known contact, is very hard to catch without verification procedures in place.
The data a family office holds carries personal consequences beyond the financial. Trust deeds, wills, succession plans and beneficial ownership records cannot be recalled once exposed. The individuals involved have a legitimate expectation of absolute privacy. Most business security frameworks are not built with them in mind.
Third-party access accumulates quietly. Accountants, lawyers, property managers and investment advisers each connect to systems over time. Without regular access reviews, no one has a clear picture of who can reach what. Some of those connections belong to people who left the family's service years ago.
Common risks
What we find when we work with family offices.
High-value target with a low-visibility profile
Family offices manage concentrated wealth across multiple entities: trusts, companies, superannuation funds and investment vehicles. Significant assets and a small, private operational footprint make them attractive to sophisticated attackers. The same discretion that characterises a well-run family office can mean security gaps go unnoticed for longer than they would in a larger, more structured organisation.
Beneficial ownership and estate planning document exposure
Wills, trust deeds, shareholder agreements, succession plans and investment mandates contain information with consequences well beyond the financial. This data cannot be replaced or recalled after a breach. The individuals whose information is held have a legitimate expectation of absolute privacy that standard business security controls, designed for organisations with hundreds of users, rarely address.
BEC targeting wire transfers and investment instructions
Family offices frequently handle large, low-frequency wire transfers and investment instructions by email. High value, infrequent enough that each instruction feels legitimate: this is exactly what BEC attackers build campaigns around. A convincing instruction from a spoofed or compromised address, timed around a real transaction discussion, is very difficult to catch without verification procedures in place.
Small team, broad access
A family office may run with two to five staff, each with access to the full range of financial and personal information held. There are no department boundaries to limit lateral movement if a credential is compromised. Admin-level access is often the norm because restricting it feels impractical. A single compromised account typically means everything is accessible.
Third-party access without oversight
Accountants, lawyers, investment advisers, property managers and administrators regularly access family office systems. Connections to cloud platforms, document management tools and financial systems accumulate over time. The people who originally approved those connections may no longer be with the office, and no one has a current view of what external access exists or what permissions remain active.
How we help
Services calibrated for family office environments.
Small team, private environment, high-value assets. The controls that matter most address the specific attack patterns targeting family offices. We put them in place without adding operational overhead the office does not have capacity to manage.
Microsoft 365 security
enforcement, , DMARC and email authentication, configured for trust and estate documents, investment records and family information. Access review and guest account auditing to find and close third-party connections that have built up without oversight.
Fortify — managed security
Around-the-clock monitoring for a small, private environment. Most family offices cannot run security monitoring themselves. Fortify provides 24x7 SOC coverage, threat containment and monthly reporting without requiring internal security expertise. Security posture improves over time rather than degrading between annual reviews.
Security reviews
A structured assessment of your environment against the exposure profile of a family office: identity controls, third-party access, document handling, email security and backup integrity. Output is a plain-language report with prioritised recommendations the family or office manager can act on directly.
Incident response
Available around the clock. For a family office, the confidentiality implications of a breach are as significant as the financial ones. Rapid containment, forensic investigation and notification support, with discretion as a standard throughout.
Compliance
Regulatory obligations for Australian family offices.
The applicable framework depends on the structure of the office and the licences held. Most family offices face Privacy Act obligations at a minimum. Where an AFSL or trustee role applies, additional requirements follow.
Personal information obligations
Family offices hold highly sensitive personal information about the family members whose affairs they manage: financial position, health status as it affects estate planning, family relationship details and identity documents. A breach involving this information will almost always trigger NDB notification obligations. The Privacy and Other Legislation Amendment Act 2024 increased penalties for serious or repeated privacy breaches, and the individuals involved have standing to seek compensation.
AFSL and trustee obligations
Some family offices hold an AFSL or act as trustee of an SMSF or private ancillary fund. Where an AFSL is held, ASIC's cyber security expectations under s912A apply. SMSF trustees face ATO compliance requirements including secure handling of member data and contribution records. Where a private ancillary fund operates, ACNC notification requirements may apply to material incidents affecting the fund.
Payment controls and verification
For BEC targeting large transfers, process controls matter as much as technical ones. A verification procedure requiring a phone call to a known number for any transfer instruction above a threshold, and any request to change banking details, stops the most common attack pattern without sophisticated technology. This procedure, combined with MFA on email, addresses the two most common attack vectors against family office payment processes.

Why are family offices targeted by cyber attackers?
Concentrated wealth, private operations, small teams and security postures that have not kept pace with the value being protected. Attackers targeting a family office are patient and do their research. They understand the ownership structures, the key relationships and the communication patterns before they act. The goal is usually a large wire transfer, access to investment accounts, or information that has value in other ways: blackmail, commercial intelligence or family dispute contexts.
What data does a family office need to protect most carefully?
Trust deeds, wills, shareholder agreements, succession plans, investment mandates and beneficial ownership records. Beyond financial value, exposure of this information has personal consequences for the individuals involved that cannot be undone. Bank statements, investment records and tax returns also need strong controls, but the governance documents are in a different category entirely.
How should a family office manage wire transfers and investment instructions securely?
The most effective control is a verification procedure: any transfer instruction or change to banking details must be confirmed by phone to a known number before action is taken. This step requires no special technology and stops the BEC attack pattern that targets high-value, low-frequency transactions. On the technical side, MFA on every email account and correctly configured DMARC prevent both account compromise and domain spoofing. Together, they make BEC attacks against the family office much harder to execute.
Does a family office need formal cyber security policies?
Where an AFSL or trustee licence is held, yes. s912A requires adequate risk management systems, and a cyber security policy is part of demonstrating that. Beyond the regulatory question, a family office that has not documented its approach to security, access controls, incident response and data handling has no baseline to work from when something goes wrong. The documentation does not need to be lengthy, but it needs to exist and be known to the people responsible for acting on it.
Can IronSights work discreetly with family offices?
Yes. Discretion is a baseline expectation, not a special service. We do not publicise client relationships without permission, we treat all information encountered during engagements as confidential, and our reporting goes to the people who need it rather than circulating more broadly. Most family office engagements are conducted entirely remotely. Where site access is required, we work around the operational preferences of the family.
