Family Office Services

Family Office Cybersecurity and Digital Forensics

Discreet digital forensics and privacy services for HNW principals, family offices, EP firms, and advisors. Direct expert access. Confidential by default.

What this service does

At the principal-household level, digital and physical risk cannot be separated, so we protect the whole surface: the principal, the family, and the household and staff who have access to both.

You work directly with the examiner who scopes the engagement — no junior handoffs, no call center — under an NDA signed before the first detail is shared.

Discreet by default, and built around your counsel and security team rather than around a sales motion.

Advisors, attorneys, and executive-protection firms: we co-engage alongside your existing relationship under NDA, with findings flowing to you and your client. Start a confidential co-engagement.

Engagements are confidential and structured to begin within 48 hours of the consultation.

Some service tracks are offered at a fixed fee; complex investigations are billed hourlywith a clear scope, milestone updates, and a cap agreed up front.

Quinn (Founder and CEO) oversees every engagement and reviews every case before findings leave the practice; the practitioner team executes the technical work under her methodology.

Family office engagements draw on executive threat assessment coordination, bug sweep and TSCM coordination, privacy and digital-footprint reduction, OSINT threat assessment, and personal cyber insurance coordination. Household-staff vetting uses the background investigation referral for household staff, partners, and significant introductions; field work runs through a licensed private investigator referral.

What this means for you

Device compromise and spyware concerns for principals

The question principals and their family offices bring us is quiet and specific: is the principal’s phone compromised, and who else can see what it sees?

The concern is well-founded.

In Deloitte Private’s Family Office Cybersecurity Report 2024, 43% of family offices globally reported experiencing a cyberattack within the last 12–24 months — and nearly one-third (31%) had no cyber incident response plan.

A principal’s device sits at the intersection of both numbers: it is the highest-value target in the household, and often the least governed.

The forensic questions are the ones we answer in our casework for any monitored device, applied to a principal’s threat model.

When a phone behaves strangely — or a family member or household staffer reports something that does not sit right — we examine the device with the owner’s authorization, check it against published indicators of compromise, and document what is and is not present.

Consumer monitoring tools and targeted commercial spyware are different problems with different checks: our guide to Stalkerware Detection and Removal covers the first, and Is Someone Monitoring My Phone? walks the self-checks a principal or family member can run safely before any examination.

Where the findings may matter legally — a divorce, a dispute with former staff, litigation — the examination is run to evidence standards from the start; see Private Digital Forensics for Individuals.

The honest limit applies at this level of the market too: a finding of “no known indicators of compromise” is not proof a device is clean, and we say so.

What the engagement produces is a documented, defensible answer, an incident-response path if something is found, and a hardening plan so the family is not relying on luck the next time.

How an engagement begins

  1. Confidential consultation. NDA-protected. 30-60 minutes. Direct conversation, no sales process.
  2. Scoped engagement. Written proposal with defined deliverables and pricing — fixed fee where it applies, hourly with milestone caps for open-ended investigations.
  3. Investigation and findings. Court-admissible standards. Written report you can act on.

Why this work matters

Family office cybersecurity is different: the attack surface is the principal, the household, and everyone with access to both.

Plain terms

What we are — and what we are not

What we are

A digital forensics practice with an AI agent at the center. Credentialed examiners, documented chain of custody, explainable findings you can verify, and court-admissible reports under FRE 901/902. When field work is needed — backgrounds, locates, physical surveillance — we coordinate with licensed private investigators. Lawful, confidential, on your side.

What we are not

Spyware, stalkerware, or a way to secretly monitor another person. We do not “hack back,” promise guaranteed money recovery, or touch any account or device without its owner's lawful authorization — and we decline engagements that ask us to.

Frequently asked about family office services

What does the family office cybersecurity service include?
Principal protection (hardened devices and accounts, secure communications, travel security posture, executive-protection coordination), household and staff infrastructure (segmented home networks, smart-home device isolation, household-staff access controls, vendor governance), threat intelligence (open-source monitoring of principal name and family, dark-web monitoring for credentials and financial info, geopolitical risk briefings), incident response retainer with same-hour engagement, and vCISO-grade strategic advisory. The work blends physical and digital risk because at the principal household level they cannot be separated.
Do you work with single-family offices, multi-family offices, or principals directly?
All three structures. Single-family office: engagement is between the practice and the SFO, with deliverables flowing to the principal and family. Multi-family office: typically a wholesale engagement covering MFO operations plus per-principal pricing for direct family engagements. Principal-direct: rarer, typically high-stakes individuals without a family office structure or with a private-counsel-led model. The engagement letter and confidentiality terms adjust to the structure.
What is the typical engagement size?
Annual family-office programs typically begin in the low six figures and scale with the breadth of the surface covered — the principal, the household, the staff with access, and the threat picture around them. Smaller targeted engagements (single-principal hardening, a household network rebuild, a vendor risk audit) are scoped to the specific work. We don't publish a rate card: pricing is set privately after a confidential assessment, and reflects sustained senior-practitioner involvement, not data volume.
How do you handle access to sensitive principal information?
Engagements run under a confidentiality agreement signed by the practice and every team member who will touch principal data, with explicit role-based access (who can see what), separated working environments per principal where multi-principal exposure exists, and documented data-handling and destruction protocols. Communication uses Signal or principal-controlled secure channels by default. Physical-document handling and device-handling protocols are aligned to principal counsel's preferences.
Can you support principal travel and coordinate with executive protection providers?
Yes. Pre-travel digital posture (burner devices, regional VPN, bricked phones in-region for high-risk jurisdictions), in-region monitoring, physical-security coordination with the principal's EP detail or external EP vendor, and post-travel device sanitization. The work integrates with the EP team's protocols, not in conflict with them.
How do you manage household staff and contractor risk?
Household staff and contractors are statistically the highest-frequency vector for principal data exposure. We run periodic background-check refreshes (with appropriate consent), device-and-network access governance (separate household-staff network, no access to principal devices, controlled email and messaging), departure-protocol enforcement (revoke access cleanly, recover devices, change shared credentials), and, where counsel approves and disclosure policy permits, open-source monitoring for leaked household credentials, documents, or principal information.
