Family office security services combine close protection, physical site security, cyber risk management and household vetting into one coordinated programme protecting a family's people, property and information. In the UK, this typically involves SIA-licensed personnel, 24/7 monitoring and coordinated response — with 70% of family offices globally now ranking cybersecurity as their top operational risk in 2026.

Key Takeaways

Cybersecurity has overtaken physical threats as the top concern for family offices, with 70% ranking it their leading operational risk and 60% reporting at least one cyberattack, according to the AlTi Tiedemann Global and Campden Wealth Ltd survey.
83% of family offices are concerned about deepfake and impersonation campaigns targeting principals, per the Omega Systems 2026 Financial Services Cyber Resilience Survey.
Only 60% of family offices feel confident detecting AI-driven cyberattacks, below the 69% average across financial services generally, according to the same Omega Systems survey.
71% of single-family offices report only "somewhat confident" ability to prevent a cyberattack, per RSM US's 2026 Family Office Operational Excellence Survey.
Priority First has secured over £1.6 billion in client assets across prime central London and UK-wide contracts, operating 24 sites on one accountable platform.

What is family office security?

Family office security is a coordinated programme of physical protection, cyber risk management and operational controls designed to protect an ultra-high-net-worth family's principals, property, staff and sensitive information. It sits alongside — and increasingly overlaps with — the wealth management, legal and tax functions that a family office typically houses under one roof.

A family office differs from a standard corporate security client because the assets being protected include people, not just premises. Principals, spouses, children and elderly relatives may all require different levels of protection, often simultaneously, across multiple residences and jurisdictions.

The scope of a family office security service usually spans four areas: residential security (manned guarding, CCTV monitoring and access control at private homes), executive close protection (personal protection for principals during travel, public appearances or high-risk periods), cybersecurity (protecting financial data, communications and digital identities), and staff vetting and household risk management (background checks for domestic staff, drivers, nannies and contractors).

The number of single-family offices has grown sharply as global wealth concentrates. The United States alone now hosts an estimated 147,950 ultra-high-net-worth individuals — roughly one third of the world's UHNW population — with single-family offices growing in tandem, according to Altrata's Wealth-X UHNW Wealth Report 2026. The UK has seen a comparable rise, particularly in prime central London boroughs such as Mayfair, Knightsbridge and Chelsea, where family offices cluster near private banks, law firms and wealth managers.

Why do family offices need dedicated security services?

Family offices need dedicated security services because they hold concentrated, high-value information and assets that make them attractive targets for both physical and cyber-enabled crime. Standard corporate security or generic residential guarding often lacks the discretion, flexibility and cross-domain coordination that protecting a family — rather than a building — actually requires.

The risk landscape has shifted markedly. More than seven in ten family offices (71%) now believe they are more likely to suffer a cyberattack than they were a few years ago, according to the Dentons Evolving Risk Landscape for Family Offices Survey Report. Physical and digital threats increasingly converge: a compromised smart home system, a spoofed courier delivery or a socially engineered household staff member can each open a route into a family's finances or safety.

Karl V. Hopkins, Partner and Global Chief Security Officer at Dentons, put it plainly: "The risks to family offices are no different than to financial institutions, law firms or information technology providers – they contain a treasure trove of sensitive and potentially lucrative information and malicious actors want it."

Data breach rates are also rising. 28% of middle market executives surveyed said their organisations experienced a data breach in the last year, up from 20% in the 2023 survey, according to RSM US's Family Office Cybersecurity Report. Legacy IT compounds the problem: family offices' reliance on on-premises or outdated systems would hinder recovery from a cyber incident for a majority of them, against a 50% average across financial services generally, per Omega Systems.

The insider threat problem

Family offices are also unusually exposed to insider risk, simply because so many people — drivers, housekeepers, tutors, contractors — have privileged access to a family's homes, schedules and routines. Christina Churchill, Principal in Management Consulting at RSM US, has described a routine finding from her site visits: "A routine exercise I practice when visiting family offices is walking around the desks and turning over computer keyboards. More often than not, I'll uncover at least one sticky note with passwords for the online accounts of family members."

This is precisely why vetting standards for household and site staff matter as much as the technology deployed. A guarding contract without documented vetting, supervision and accountability is a gap dressed up as a service.

What physical security measures protect family offices and residences?

Physical security for family offices centres on manned guarding, access control, CCTV monitoring, key holding and alarm response — delivered by SIA-licensed personnel under the Private Security Industry Act 2001. Every measure should be photographable and auditable, not simply asserted, so that principals and their advisers can verify cover was actually delivered.

The Security Industry Authority (SIA) licenses close protection operatives, security guards and door supervisors, and maintains a public Regulated Professions Register confirming an individual's licence status. Any family office engaging security personnel — whether directly or through a facilities partner — should confirm SIA licensing as a baseline, non-negotiable check.

Core physical measures typically include:

Manned guarding at residences, offices and staff accommodation, with SIA-licensed officers on rotating shifts.
CCTV monitoring with remote operators who can escalate suspicious activity in real time rather than relying on retrospective footage review.
Key holding and alarm response, so a trained responder — not a family member or untrained staff — attends every activation.
Access control across gates, entry points and internal zones, distinguishing family, staff, contractors and visitors.
Vacant property protection for second homes or properties between occupancy, where empty buildings are a known target for theft and squatting.
Executive close protection for principals travelling, attending public events or facing an elevated personal risk period.

Priority First's own operational data illustrates why provability matters. Across its largest managed portfolio, the company now runs 24 sites on one platform, up from 18 at the previous count, with more than 4,900 photo-backed patrols completed — every one carrying officer ID, GPS location and a timestamp. Missed checkpoints show as gaps in the record rather than passing silently. That standard of evidence is precisely what a family office needs when a principal, family lawyer or insurer asks a simple question: was the property actually checked, and when?

In one anonymised example from Priority First's client base, an office in the Chelsea and Knightsbridge area faced a familiar problem: the building's risk profile inverted at the end of the working day, as deliveries and contractor access continued while occupancy dropped towards zero. Priority First deployed SIA-licensed officers whose every patrol, incident and handover was logged on its platform, with checkpoints completed via photograph, GPS and timestamp — turning "we covered the site" into a provable record, for a cost in the region of £15,000 a year.

How does cybersecurity fit into family office security services?

Cybersecurity is now inseparable from physical protection in a family office context, because the same principal targeted by a break-in attempt may also be targeted by a deepfake phone call impersonating them to a bank. Family offices manage concentrated financial and personal data with comparatively thin IT teams, which makes them a disproportionately attractive target relative to their size.

The confidence gap is stark. Only 60% of family offices believe their teams can detect or prevent AI-driven cyberattacks, against a 69% average across financial services more broadly, according to Omega Systems. Meanwhile, 71% of single-family offices describe themselves as only "somewhat confident" in their ability to prevent an attack at all, per RSM US.

Mary Timmons, Chief Operating Officer of Global Family and Private Investment Office Services at Northern Trust, frames the stakes clearly: "Strong cyber systems are an essential component of family office practices. Protecting families' assets, along with their privacy, is job number one."

Practical cyber measures a UK family office should expect include:

Multi-factor authentication across all financial and communication platforms.
Regular penetration testing and vulnerability scanning, ideally benchmarked against a recognised framework such as ISO 27001.
Staff and family training on deepfake and impersonation red flags, given a large majority of family offices already report concern about this specific threat, per Omega Systems.
Clear incident response protocols, tested rather than merely documented — since most family offices admit legacy systems would hinder recovery.
Coordination between the family office's IT provider and its physical security contractor, so a compromised access control system or smart-home hub is treated as a security incident, not just an IT fault.

For data protection compliance specifically, UK family offices handling personal data should note their obligations under the Information Commissioner's Office (ICO) framework and the UK GDPR, particularly around data retention for staff vetting records and CCTV footage.

Physical security vs cybersecurity: where should a family office start?

Most family offices ask whether to prioritise physical protection or cybersecurity first. The honest answer is that the two cannot be sequenced — they must be planned together, because a weakness in one routinely becomes the entry point for an attack in the other.

Consideration	Physical security	Cybersecurity
Primary threat	Burglary, intrusion, personal safety risk	Data breach, fraud, deepfake impersonation
Typical UK regulator/standard	Private Security Industry Act 2001, SIA licensing	ICO / UK GDPR, ISO 27001
Family offices citing it as top risk	Rising, but secondary to cyber in recent surveys	70% rank it top operational risk (AlTi/Campden)
Confidence level reported	Varies by provider quality	Only 60% confident in AI-threat detection (Omega Systems)
Typical UK delivery model	SIA-licensed manned guarding, CCTV, key holding	Managed IT/security partner, staff training
Evidence of delivery	Photo-backed patrols, GPS timestamps, incident logs	Penetration test reports, audit logs, MFA enforcement

In practice, an integrated family office security programme treats physical and digital controls as one system: the same governance that vets a housekeeper should govern who has admin access to the family's banking portal.

What does family office security cost in the UK?

Family office security costs in the UK vary enormously depending on the number of properties, the level of principal protection required, and whether cover is 24/7 or scheduled. As an illustrative benchmark, static manned guarding for a single commercial or residential site in prime central London typically runs in the region of £15,000 a year for a defined coverage window — the figure Priority First has delivered for office clients in the Chelsea and Knightsbridge area.

Costs scale with complexity rather than headcount alone. A family with one London residence and occasional close protection needs will pay far less than one running multiple UK properties, international travel security and a dedicated cyber monitoring contract.

Illustrative cost drivers include:

Coverage hours: scheduled daytime cover costs less than genuine 24/7 static presence.
Number of sites: multi-property families benefit from consolidating providers, since a single accountable partner reduces duplicated management overhead.
Close protection requirements: dedicated executive protection officers for travel or events add cost beyond standard guarding.
Technology layer: CCTV monitoring, access control integration and photo-backed patrol reporting add a modest premium but materially improve accountability.
Cyber monitoring: increasingly bundled or coordinated with a family office's existing IT provider rather than run as a separate silo.

Ways to reduce costs without reducing protection

Families can often reduce spend by consolidating guarding, key holding, CCTV monitoring and facilities management under one provider rather than running separate contracts with separate management fees. Insisting on photo-backed, auditable patrols also reduces the cost of disputes and insurance claims, since delivered cover is provable rather than argued over after the fact.

Alternatives to consider

Not every property needs permanent static guarding. Mobile patrols, remote CCTV monitoring with rapid response, and alarm-triggered key holding can deliver adequate protection for lower-risk secondary residences at a fraction of the cost of full-time officers.

How do you vet and manage a family office security provider?

Vetting a family office security provider means checking SIA licensing, requesting evidence of how cover is actually delivered, and confirming accountability when things go wrong — not simply accepting a glossy proposal. Mo Hassan, Managing Director of Priority First, is direct about what a credible tender should contain: "A strong tender names the people who will actually deliver the contract, explains how cover is maintained when things go wrong — sickness, no-shows, emergencies — and prices transparently enough that you can see the officer's pay within it. Glossy documents that avoid those three subjects are telling you something."

Practical due diligence steps include:

Confirm every proposed officer's SIA licence status via the SIA Regulated Professions Register.
Ask how patrols and checkpoints are recorded — a paper occurrence book is far weaker evidence than photo-backed, GPS-timestamped reporting.
Request references from comparable residential or family office clients, ideally in the same borough or property type.
Clarify escalation protocols: who is contacted first during an alarm activation or duress event, and within what timeframe.
Establish how staff turnover and sickness cover is managed, so protection doesn't lapse when an individual officer is unavailable.

One family office client, James Burmingham, described this kind of transition in his own words: "We recently hired Priority First to handle the security needs for our business, and we couldn't be more impressed! From the initial consultation to the implementation of security systems, their team was professional, knowledgeable, and incredibly responsive."

Your family office security checklist

Confirm SIA licensing for every officer via the official Regulated Professions Register.
Require photo-backed, timestamped patrol records rather than paper occurrence books.
Map every physical access point across residences, offices and staff accommodation.
Vet household staff, drivers and contractors with the same rigour as financial hires.
Coordinate physical security and IT teams so incidents are reported to one accountable point.
Test cyber incident response protocols at least annually rather than leaving them undocumented.
Review key holding and alarm response arrangements for every property, including secondary and vacant homes.
Reassess coverage levels whenever a principal's public profile or travel pattern changes.

FAQ

What is family office security and why is it important?

Family office security is a coordinated programme covering physical protection, cybersecurity and staff vetting for ultra-high-net-worth families and their properties. It matters because family offices concentrate significant wealth and sensitive personal information in a small operational footprint, making them attractive targets for both physical intrusion and cyber-enabled fraud.

What services are typically included in family office security programmes?

A typical programme includes manned guarding, CCTV monitoring, key holding and alarm response, executive close protection, and cybersecurity measures such as multi-factor authentication and staff training. Many UK family offices also include vacant property protection for second homes and structured vetting for household staff and contractors.

How much does family office security cost?

Costs vary by property count, coverage hours and protection level, but static manned guarding for a single site in prime central London typically starts around £15,000 a year for defined coverage. Multi-property families with close protection and cyber monitoring needs should expect significantly higher combined spend, scaled to the specific risk profile.

What is the difference between executive close protection and general family office security?

Executive close protection specifically covers personal protection for an individual during travel, public appearances or elevated-risk periods, delivered by trained SIA-licensed close protection operatives. Family office security is the broader umbrella covering that protection alongside site security, CCTV, key holding and cyber risk management across the whole family.

How often should a family office review its security measures?

A family office should review its security arrangements at least annually, and immediately after any change in a principal's public profile, travel pattern or property portfolio. Cyber protocols in particular should be tested rather than simply documented, since a majority of family offices admit legacy systems would hinder recovery from a cyber incident.

What are the biggest cybersecurity risks facing family offices?

The leading risks are deepfake and impersonation attacks targeting principals, AI-driven phishing, and legacy IT systems that hinder incident recovery. A large majority of family offices report concern about deepfake and impersonation campaigns specifically.

How do family offices protect against insider threats from staff?

Family offices reduce insider risk through structured background checks on household staff, drivers and contractors, combined with access controls that limit who can view sensitive schedules or financial information. Basic hygiene matters too — RSM US's Christina Churchill has noted that passwords on sticky notes under keyboards remain a common finding during family office site visits.

What licences should close protection and guarding personnel hold in the UK?

Close protection operatives, security guards and door supervisors in the UK must hold a valid licence from the Security Industry Authority under the Private Security Industry Act 2001. Families and their advisers can verify any individual's licence status directly via the SIA's Regulated Professions Register before engagement.

Securing your family office with Priority First

Family office security demands the same discretion, accountability and evidence standard that Priority First applies across its prime central London portfolio — because a family's home deserves the same provable, photo-backed protection as a commercial building, not less. Priority First already delivers manned guarding, key holding, CCTV monitoring and concierge services across residential and commercial sites in Chelsea, Knightsbridge, Mayfair and West London, alongside contracts in the West Midlands and Bedfordshire.

Priority First's operational data shows over £1.6 billion in client assets currently protected across its portfolio, with every checkpoint requiring a photograph to complete — so missed patrols show as gaps in the record rather than passing silently. That standard applies equally to a commercial office and a family residence.
