Do You Need a Personal Cybersecurity Concierge?
By Oakstone Security Group
May 1, 2025
If you have a security system at home, a trusted lawyer, and a financial advisor who has known you for years, you might feel reasonably well protected. You are not wrong to feel that way. But there is a gap in that picture that is increasingly being exploited, and it does not involve your front door.
High-Net-Worth Individuals Are Not Random Targets
Most cybercrime is opportunistic. Attackers cast wide nets, exploit known vulnerabilities at scale, and move on. But a meaningful and growing category of attack is not opportunistic at all. It is targeted, patient, and personal.
Wealthy individuals, executives, and public figures are attractive targets for a specific reason: the potential return on investment for an attacker is orders of magnitude higher than it would be against a typical household. A successful attack against the right person can yield direct financial theft, leverage for extortion, access to sensitive legal or business information, or intelligence that enables further attacks against connected parties.
The FBI’s Internet Crime Complaint Center reported over $12.5 billion in losses from cybercrime in 2023. Business email compromise and investment fraud were among the top categories, and the victims were disproportionately individuals with assets worth stealing. These are not statistics about careless people clicking suspicious links. They are statistics about capable, educated professionals being systematically deceived by patient and well-resourced adversaries.
The Attack Surface Is Personal, Not Corporate
Corporate cybersecurity is well understood. Businesses have IT departments, firewalls, endpoint detection, and compliance requirements that impose a baseline of security hygiene. The personal lives of the people who run those businesses are a different story.
The attack surface of a high-net-worth individual is wide, personal, and largely undefended:
Family members. A CEO’s company may have excellent security. His teenage daughter’s phone, connected to the same home network, may not. Attackers who cannot get through the front door of a corporate network will look for a side entrance, and family members are a well-documented vector.
Personal email and cloud accounts. Personal email accounts are rarely managed with the same rigour as corporate ones. They often hold years of financial records, legal correspondence, property documents, and communications with advisors. Compromise of a personal Gmail or iCloud account can be more damaging than a corporate breach.
Advisors and professional relationships. Lawyers, accountants, family office staff, and wealth managers are targeted because they have trusted relationships with their clients. A convincing email that appears to come from a client’s solicitor, asking to update payment details before a closing, does not require sophisticated technical intrusion. It requires only that the recipient trusts the sender.
Home networks. Smart home devices, security cameras, and connected appliances are frequently poorly secured. A compromised device on a home network can be used as a persistent foothold from which to monitor activity, intercept communications, or pivot to more sensitive systems.
Public profile and open-source intelligence. An astonishing amount of information about wealthy individuals is publicly accessible. Property records, company directorships, court filings, social media, and press coverage collectively paint a detailed picture that a motivated attacker can use to craft highly convincing approaches. The reconnaissance for a targeted attack often requires no technical capability at all.
Travel. Hotels, airport lounges, and border crossings in certain jurisdictions present specific risks to devices and data. Devices connected to untrusted networks, left unattended, or presented for inspection at borders have been compromised in ways that would not have been possible in a controlled home or office environment.
What a Personal Cybersecurity Concierge Actually Provides
The term sounds like a luxury. In practice, it describes something straightforward: a security professional who applies the same rigour to your personal life that a corporate CISO applies to a business, adapted to your specific circumstances.
The engagement begins with a threat assessment. Not a generic checklist, but a structured process designed to understand your particular exposure. Who are you? What do you own? Who knows you? What could a motivated and well-resourced adversary learn about you without ever touching a keyboard? The results of this exercise routinely surprise clients who consider themselves security-conscious.
From that baseline, the work covers the vulnerabilities that matter most:
Device and account hardening. Every personal device and account in your household, reviewed and secured. Strong authentication enforced. Account recovery paths audited. Dormant access removed. The objective is to make opportunistic compromise significantly harder and targeted compromise significantly more expensive for an attacker.
Home network architecture. Your home network redesigned so that devices cannot reach each other unnecessarily. Smart home systems, guest networks, and personal computers operate in isolation. A compromised camera stays a compromised camera rather than becoming a doorway to everything else.
Advisor communication security. Secure, verified channels established for communications with legal counsel, financial advisors, and other parties with whom you discuss sensitive matters. When an instruction arrives purportedly from a trusted source, there is a way to confirm it is genuine.
OSINT reduction. A review of what is publicly visible about you and your family, and where possible, active steps to reduce or manage that exposure. This does not make you invisible, but it raises the cost of the reconnaissance that precedes a targeted attack.
Travel preparation. Before travel to higher-risk jurisdictions, devices prepared and a clear brief on the specific risks and mitigations relevant to your itinerary.
Ongoing availability. Security concerns do not observe office hours. An ongoing advisory relationship with Oakstone means that when something does not feel right, there is someone to call who already knows your environment.
Why Oakstone
There are large firms that offer security services to corporations. There are managed security providers that will sell you monitoring dashboards and quarterly reports. Neither of those is what personal security work requires.
Personal security work requires a small team that can hold detailed knowledge of a specific client’s life, relationships, and risk profile. It requires discretion as a baseline, not a policy. It requires the kind of availability that institutional providers structurally cannot offer. And it requires the judgment to distinguish between what is important and what is noise, without defaulting to corporate-grade responses that are disproportionate to a personal context.
Oakstone works with a deliberately limited number of individual and family clients. That is not a constraint. It is the point. The depth of understanding we develop about each client’s circumstances is what makes the work effective, and that depth is only possible when the client list is small.
We do not advertise who we work with. We do not discuss our engagements. We treat confidentiality not as a feature but as a foundation.
Is This for You?
If you are reading this and wondering whether your current exposure warrants a conversation, the honest answer is that it probably does. Most people in the relevant category have significant unaddressed exposure they are not aware of, not because they have been careless, but because the personal threat landscape has evolved faster than most people’s awareness of it.
A preliminary assessment carries no obligation and will give you a clear and specific picture of where you stand.
