BureauVault On-Premise AI That Never Leaves The Building

BureauVault™ On-Premise is The Agent Bureau's on-site AI stack for UK SMEs that need data sovereignty. A fully managed server smaller than a sheet of A4 keeps Bureau or bespoke Smart Assistants inside your building—with human oversight. From £1,095/mo ex VAT — reliable capacity, not another DIY AI experiment.

The On-Premise Stack for Smart Assistants that never leave your building

BureauVault™ puts the same private Smart Assistant platform as BureauCore™ inside your premises. Choose On-Premise or Sovereign infrastructure, add AI Calling, then stack modules. Footprint half a sheet of a4. Data never leaves the building.

01The Real Question

How do we run Smart Assistants when our DPO won't sign off a US cloud?

"UK region" hosting answers where data sits, not who can compel access to it. Under the US CLOUD Act, US providers can be required to disclose data regardless of region. Assistant workloads — including call recordings when you add voice — are personal data; in health, legal, finance and recruitment they routinely contain special category data.

02The Bureau Angle

The hardware comes to you. The management stays with us.

The hardware comes to you; management stays with us. Built for firms that fear data theft or third-party access: On-Premise or Sovereign infrastructure, AI Calling, then modules — processing never leaves the building. Same Smart Assistant platform as BureauCore™ Hosted, installed on-site.

03The Result

A simpler DPIA and a flat bill

On-Premise infrastructure £1,095/mo; Sovereign £1,995/mo with up to 3 concurrent lines, custom voices and contractual SLAs. The full AI Call Centre In A Box stack — server plus 1,000 calls a week — lands at £2,090/mo. Ex VAT, 12-month minimum. Hardware never sold. Typical go-live around 14 days.

  • Flat fee vs per-minute climb

    Outsourced per-minute and answering rates rise when you succeed; Vault stays flat

  • Roster or bespoke on the box

    Same Smart Assistant platform as BureauCore™ — sovereignty without a call-only SKU

From Kickoff
to Assistants Live.

Discovery, private stack build, install and sandbox, then go live. Smart Assistants — Bureau roster or bespoke — connect to your CRM and calendars. Bespoke Operations, calling and BureauProducts on the stack are workloads; content and documents share the box.

  • 01

    Install the private stack

    Half a sheet of A4 footprint. Day 1 discovery → Day 5 build → Day 10 install + sandbox → Day 14 assistants live.

    Deploy assistants you need

    Reception-class, sales-class, finance/admin-class or fully bespoke — configured for your tone and tools.

Smart Assistants on Private UK Infrastructure

Same private Smart Assistant stack as BureauCore™, installed inside your building. Data never leaves it. Run existing Bureau roster assistants or commission bespoke builds — managed subscription, footprint half a sheet of A4, hardware never sold.

Fig. 06-A — Assistants on BureauVault™TAB / UK
  • 01

    Bureau roster + bespoke builds

    Run the Smart Assistants that already staff Bureau desks — reception, sales, finance admin, marketing, care and more — or commission bespoke assistants designed for your workflows, tools and tone.

  • 02

    Bespoke Operations

    Custom operational workflows on your private stack — triage, scheduling, admin processing, handoffs and the SOPs your team already runs — designed and managed by The Agent Bureau, not a generic chatbot.

  • 03

    UK-processed, private stack

    Shared or dedicated UK hardware we manage (hosted), or installed inside your building (on-prem). Voice and assistant data stay under UK residency — or never leave the premises on Vault.

  • 04

    Unbundled, flat contracted fees

    Infrastructure, AI Calling and modules are priced in clear steps — no per-token surprise bills when volume grows. Hardware is never sold.

  • 05

    Multiple workloads, not calls alone

    Calling and BureauReach™ Sales Desk run on the stack. The same infrastructure runs Bespoke Operations, content, image, document, website voice and other assistant work your business needs.

  • 06

    Step-up path: Core → Vault → Suite

    BureauCore™ Hosted for UK-managed go-live in days. BureauVault™ when data must stay in the building. BureauSuite™ 360 when you want assistants and modules on one box, one fee.

  • 07

    Human oversight included

    The Agent Bureau® configures, monitors and supports the stack. Warm escalation paths sit beside the assistants — not a black-box dialler you babysit alone.

/10Integrations

Lives in your Stack.

BureauVault™ connects CRM, calendar and numbers so assistants write into your stack — while primary processing never leaves the building. Optional cloud fallback for continuity.

Stack dossier / 01 of 06

Integrations

Your CRM

The pain

"Assistants that live outside your CRM leave notes in parallel systems — or nowhere — so specialists still chase context before every follow-up."

The solution

BureauCore™ and BureauVault™ Smart Assistants write attempts, bookings and outcomes into HubSpot, Pipedrive, Salesforce or the CRM you already run — sovereignty without a second notebook.

Stack dossier / 02 of 06

Integrations

Google Calendar & Outlook

The pain

"Diary ping-pong stretches enquiry-to-meeting into days while warm leads cool — and out-of-hours intent never reaches a bookable slot."

The solution

Assistants book live into Google Calendar or Outlook with SMS confirm, respecting your calling windows and capacity rules on the private stack.

Stack dossier / 03 of 06

Integrations

Phone numbers

The pain

"New numbers, porting and provider juggling sit between “we bought AI” and anything actually ringing — especially when residency matters."

The solution

UK numbers provisioned or ported onto the hosted or on-prem box. Calling is one workload; the same agents still own SMS, CRM capture and handoffs.

Stack dossier / 04 of 06

Integrations

BureauCRM™

The pain

"Without a shared spine, desk outcomes and infrastructure workloads drift apart — reception, sales and finance each keep a private version of the truth."

The solution

Every assistant attempt, promise and outcome can land on the Job Card and Callback Promise in BureauCRM™ — so BureauDesk™ and the rest of the Bureau share one honest book.

Stack dossier / 05 of 06

Integrations

BureauDesk™

The pain

"Teams that already trust the reception desk still hit a wall when volume, bespoke assistants or residency demand dedicated hardware."

The solution

BureauDesk™ Smart Assistants already run on this layer. Step up to BureauCore™ or BureauVault™ when you need the private box — same roster patterns, dedicated UK (or on-prem) stack.

Stack dossier / 06 of 06

Integrations

Cloud fallback

The pain

"All-or-nothing on-prem plans leave buyers nervous about continuity; all-cloud plans reintroduce the jurisdiction risk they came to escape."

The solution

Optional cloud fallback keeps continuity without making the US public cloud the default home for voice and assistant data. Primary processing stays on BureauCore™ / BureauVault™.

Reported outcome

~18 hrs/week returned · £12.4k found per building

We engaged The Agent Bureau to solve a real pain point in UK block management: out-of-hours communication and secure ticket logging. TAB delivered a smart assistant that operates as our frontline 24/7, with BureauGovern™ keeping the AI usage policy and human-oversight evidence behind every controlled action. What impressed me most is the reliable caller verification before anything is logged. The conversation quality is human-level; residents feel heard at any hour, and it bridges the gap between technology and human empathy.
