Why this exists
Most businesses want private AI without buying a server room.
The Gateway gives you a private assistant in weeks, not a hardware project. The privacy is in how it's built, not in a box in the corner.
Your questions run through a private, UK-hosted gateway that we run for you. It retrieves answers from your own data, keeps everything in the UK, and never lets a public model train on a word of it, with a full audit trail your compliance team can read.
How it stays private
Built for confidential work from the first line.
Everything stays in the UK
The gateway and your data sit in a UK region. Nothing is stored outside the country, and nothing is used to train a public model, ever.
Knows your business
It reads your own documents, emails and records to answer, with a source for every reply. A blank chatbot becomes an assistant that actually knows your firm.
Permissioned and audited
People see only what they are allowed to, and every question and answer is logged with who asked and when, ready for a GDPR audit or regulator review.
A human stays accountable
Anything that matters is set up so a person signs off. You get the speed of AI with a clear line of responsibility.
The models it runs
The best model for each question, privately.
Top models, on tap
The gateway can call leading managed models like Claude, GPT and open models such as Llama, so you always get a capable answer without running any of them yourself.
Routed, not exposed
Sensitive material is handled inside your private environment; only non-sensitive reasoning is sent onward, through a zero-retention gateway that keeps nothing.
UK region, zero retention
Model access runs in a UK region with retention switched off, so prompts aren't kept or reused. We confirm the exact terms with you in writing.
Need nothing at all to leave your walls, even to a managed model? That's our Nerdster Vault Open-Model tier: a dedicated model that runs entirely inside your own environment.
FAQ
The Vault Gateway, answered.
How is this different from just using ChatGPT at work?
Public ChatGPT sends your text to a third party with your data mixed into a consumer service. The Gateway runs through a private, UK-hosted layer we control: it answers from your own documents, keeps everything in a UK region, turns off retention, and logs every prompt. Same "ask anything" feel, kept private and accountable.
Do we need to buy a GPU or a server?
No. The Gateway uses managed models, so there is no hardware to buy and it goes live in weeks. If your rules require a model that runs entirely on your own dedicated hardware, that's the Private Open-Model tier instead.
Is our data ever used to train a model?
No. Retention is switched off and training on your data is contractually excluded. We confirm the exact region and data-handling terms with you in writing before anything goes live.
Who is it for?
Any business that wants a capable private assistant without an IT project: professional services, clinics, agencies and SMEs. If you specifically can't send data to any outside model at all, look at Private Open-Model.
What does it cost?
You start with a fixed-price pilot from £1,500 on one team, then, if you keep it, from £299 a month including a fair-use allowance, with heavier use billed transparently on top. Every figure is agreed in writing first, and there is no long contract.
