Consistent

A vetted support team with shared knowledge of your setup

Household security to the standard a firm secures its office

Your home now runs on technology. The doors, the cameras, the heating, the family’s phones and the staff’s laptops all sit on one network. Almost none of it was set up with security in mind.

We give private households in London the same discipline we give regulated firms. Quietly, and without turning your house into an office.

The gaps your smart home opens

Smart home kit is convenient. It is also a row of doors nobody checks. Lighting, speakers, cameras and blinds all sit on the network, and most were installed with the default password still on them.

We assess the whole connected estate. We put IoT devices on their own segment, so a compromised camera cannot reach a family laptop. We update firmware, remove default credentials, and monitor connected devices for behaviour that does not fit.

AI voice clones, and how families get fooled

A convincing voice clone now takes seconds of audio. That audio is easy to find — a social post, a speech, a voicemail greeting.

The cloned voice calls a family member, a house manager or a financial adviser. It asks for an urgent transfer, or for information. It sounds right, because it is built from a real voice.

Technology alone does not stop this. We agree a code word with the family. We set a rule that money requests get confirmed on a second channel. We put detection tools on the devices. Then we brief the family and the household staff on what to listen for, so the defence works when the call comes.

The digital footprint your family leaves behind

Property records, company filings, school affiliations, travel photos and charity listings all sit in public. Attackers read them and build a targeted approach from what they find.

We monitor the dark web for your credentials. We review public profiles for what they give away. We harden personal devices against the malware used in targeted attacks. Then we talk you through what to change, and we change what we can on your behalf.

A team that understands your household

What matters most in a household is continuity: a trusted team that understands the properties, systems and preferences involved.

That is what you get. A consistent team handles the family’s technology, from a new iPhone to a phishing attempt. The setup is documented, access is controlled and you know who is dealing with it.

The things your money cannot rebuild

Investments can be restructured. Privacy cannot. Once a family’s movements, photographs or conversations are out, no amount of work brings them back.

We bring the discipline we use for London’s financial firms into the private household, and apply it to the people rather than the portfolio.

What you get from us

Harden the smart home

We assess every connected system — lighting, heating, CCTV, access control — and fix what an attacker could use. IoT devices sit on their own network, away from family laptops and personal data.

Guard the family's digital identity

We watch the dark web for your credentials, review what your public profiles give away, and harden personal devices. You hear from us before a problem reaches the household.

Manage every family device from one place

Phones, tablets and laptops all patched, encrypted and monitored under one plan. Children get age-appropriate controls that change as they grow.

A consistent team that knows the setup

A vetted support team keeps useful records of your properties and preferences, with documented cover when a different specialist is needed.

FAQ

Frequently asked questions

Why does a private household need specialist cybersecurity?

Attackers target wealthy households because the payoff is large and the defences are usually weaker than a company's. Smart homes add doors that nobody audits. AI voice cloning makes impersonation cheap. And family life mixes personal and business technology, so one breach reaches everything.

What does a cybersecurity concierge do?

It gives you one discreet service for the family's technology. A suspicious email, a new phone to set up or a smart-home system playing up goes to a consistent team that keeps useful knowledge of the setup.

How do you protect against AI voice cloning scams?

We set up verification the family actually uses: an agreed code word, a second channel to confirm any money request, and detection tools on the devices. We also brief family members and household staff on what these calls sound like, so the human layer works even when the technology is convincing.

Can you secure our smart home systems?

Yes. We review cameras, access control, lighting, heating, audio and the network behind them. We fix what we find, put IoT devices on a separate segment away from personal data, and monitor the connected estate for behaviour that looks wrong.

Do you cover children and younger family members?

We set age-appropriate controls: content filtering, screen time, device security and location sharing. We pitch them so they hold rather than get worked around, and we loosen them as children get older.
