RAG at organisational scale

Enterprise RAG Solutions

A departmental RAG pilot handles one clean source. Enterprise RAG handles nine messy ones, three permission models, five years of superseded versions, and an audit requirement.

The problem

Four problems that only appear at enterprise scale

Each is solvable. None is solved by a demo.

Version conflict: the same policy exists in four places with different dates and nobody has deleted the old ones. We resolve currency at ingestion using metadata, folder conventions and explicit supersession rules, and surface the conflict where it cannot be resolved automatically.

Permission mapping: SharePoint groups, Drive sharing and database roles do not use the same model. We map each to a common ACL representation and filter at query time so answers respect the asking user's actual access.

Scale of change: thousands of documents change weekly. Full re-indexing is not viable, so ingestion is incremental with change detection.

Audit: your risk team will want to know who asked what, what was retrieved, and what was returned. That is a design requirement, not a log file.

  • Supersession rules so current documents win
  • Common ACL model across heterogeneous sources
  • Query-time permission filtering, per user, per request
  • Incremental indexing with change detection
  • Retrieval audit trail retained per policy
  • Department-level tuning on a shared platform
Use cases

Enterprise deployments

Organisation-wide knowledge assistant

One assistant across HR, IT, finance, legal and operations documentation.

Contract intelligence

Query obligations, renewal dates and clause variations across an agreement repository.

Engineering knowledge base

Specifications, runbooks and incident history across product lines and versions.

Regulatory library

Current requirements with clause-level citation and change tracking.

Bid and proposal library

Past submissions, pricing precedent and approved claims, searchable during a live bid.

Field and service knowledge

Procedures and troubleshooting retrieved on mobile by technicians on site.

How we deliver

Ten stages from first call to a system your team trusts

Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.

Discovery

A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.

AI Opportunity Assessment

We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.

Solution Architecture

Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.

Proof of Concept

A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.

MVP

One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.

Production Development

Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.

Integration

Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.

Security Testing

Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.

Deployment

Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.

Monitoring & Optimization

Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.

Security & Governance

Security-conscious architecture, from the first design review

Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.

Data privacy & residency

Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.

Role-based access control

Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.

Authentication & authorization

SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.

Encryption

TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.

API security

Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.

Audit logging

Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.

Data isolation

Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.

Secure prompt handling

System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.

PII protection

Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.

Human approval workflows

High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.

Monitoring & anomaly detection

Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.

Rate limiting & abuse control

Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.

Secure deployment

Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.

FAQ

Questions enterprise buyers ask us first

How do you handle document permissions at scale?
Access control lists are extracted at ingestion, normalised into a common model, and stored as index metadata. Every query is filtered against the asking user's resolved permissions before retrieval runs. Permission changes in the source system take effect on the next query rather than the next re-index.
What if our documents contradict each other?
Contradiction is normal in a large estate. We resolve currency where metadata and supersession rules allow, and where a genuine conflict remains the assistant surfaces both sources with dates rather than silently picking one. That surfacing has real secondary value — it shows you where your documentation needs attention.
How often is the index updated?
Incrementally, with change detection. Frequently-changing sources can sync in near real time via webhooks; stable archives run on a nightly or weekly schedule. Full re-indexing is reserved for structural changes.
Can different departments have different behaviour?
Yes. The retrieval platform is shared, but each department can have its own source scope, tone, refusal thresholds and escalation routing on top of it. That is the point of building the platform once.
