Knowledge Management at Scale: Multi-Tenant RAG with RBAC

Knowledge Management at Scale: Multi-Tenant RAG with RBAC

Leader 2 15
calendar_today agoschedule7 min read

Your organization has knowledge scattered everywhere: docs, wikis, Slack conversations, emails, databases. Your AI agents need access to it. But you can’t let every agent access every document (security, privacy). I built Socratic-knowledge: enterprise RAG (Retrieval-Augmented Generation) with multi-tenancy, role-based access control, versioning, and audit logging. Agents retrieve exactly the knowledge they need. Users stay secure.

The Problem: Knowledge Is Fragmented and Dangerous
Scenario 1: The Scattered Knowledge

Your organization has knowledge in:

Wikis (internal documentation)
Google Drive (design docs, strategy docs)
GitHub (code docs, architecture)
Slack (Q&A conversations, decisions)
Email (historical decisions, context)
Databases (product specs, configurations)
PDFs (whitepapers, research)
Your agents need this knowledge to make good decisions.

But it’s fragmented. Inconsistent. Sometimes contradictory.

Your agent searches the wiki for product specs. Gets outdated info. Your agent searches email for decision history. Gets 500 unrelated emails. Your agent searches Slack. Finds someone’s joke mixed with actual information.

Agents make bad decisions because they have bad knowledge.

Scenario 2: The Security Nightmare
You have sensitive knowledge:

Customer data
Financial information
Proprietary algorithms
Personal conversations
Some agents need access (customer support agent needs customer data). Other agents shouldn’t (recommendation engine shouldn’t see financial data). Users need to control what’s shared (customer shouldn’t see other customer’s data).

Without access control, either:

You don’t share knowledge (agents are dumb)
You share everything (security breach)

Scenario 3: The Versioning Problem
Knowledge changes. Your product specs are updated. Your strategy shifts. Your processes evolve.

Which version should the agent use?

The current version? (might break compatibility with old customers)
The version from when the agent was trained? (might be outdated)
All versions? (agent gets confused by contradictions)
Without versioning, agents work with stale knowledge.

Scenario 4: The Compliance Burden
You need to know:

Which agent accessed which knowledge?
When did it access it?
What decisions did it make based on that knowledge?
If a decision was wrong, which knowledge led to it?
Without audit logging, you have no compliance trail.

Why Standard RAG Fails for Multi-Tenant Systems
Standard RAG
Standard RAG (Retrieval-Augmented Generation):

Store all knowledge in a vector database
When agent needs knowledge, search the database
Return top matching documents
Agent uses documents to make decisions
This works for single-tenant systems. It breaks for multi-tenant:

Problem 1: Access Control

Anyone with access to the RAG system can retrieve any knowledge
No way to restrict based on role or tenant
Problem 2: Data Isolation

All data is mixed together
One tenant’s knowledge bleeds into another’s
Problem 3: Versioning

Documents are static
No way to track multiple versions

Problem 4: Audit Trail

No logging of who accessed what
No compliance trail
The Solution: Socratic-Knowledge
Socratic-knowledge is an enterprise RAG system built for multi-tenant environments.

Core Features
Feature 1: Multi-Tenancy

Complete data isolation between tenants:

Organization A:

├─ Documents (completely isolated)

├─ Knowledge base (separate)

├─ Agents (can only access org A knowledge)

└─ Users (can only see org A)

Organization B:

├─ Documents (completely isolated)

├─ Knowledge base (separate)

├─ Agents (can only access org B knowledge)

└─ Users (can only see org B)

System enforces: Organization A agents NEVER see Organization B documents
Feature 2: Role-Based Access Control (RBAC)

Fine-grained permissions:

Roles within Organization A:

Admin:

├─ Can view all documents

├─ Can edit all documents

├─ Can grant/revoke access

└─ Can view audit logs

Manager:

├─ Can view team documents

├─ Can edit team documents

├─ Can grant access to team

└─ Can view team audit logs

Employee:

├─ Can view shared documents

├─ Cannot edit

├─ Cannot grant access

└─ Cannot view audit logs

Example: Customer Support Agent

├─ Can access: Customer data, product docs, policies

├─ Cannot access: Financial data, employee records, future roadmap

└─ Can only see data for assigned customers

Feature 3: Document Versioning

Track changes over time:

Product Specification Document

Version 1 (Jan 2026):

├─ SKU: 123

├─ Price: €49.99

├─ Description: "Widget v1"

└─ Status: Active

Version 2 (Mar 2026):

├─ SKU: 123

├─ Price: €59.99 (updated)

├─ Description: "Widget v1.5" (updated)

└─ Status: Deprecated

Version 3 (May 2026):

├─ SKU: 456

├─ Price: €69.99 (new product)

├─ Description: "Widget v2"

└─ Status: Active

Agent using version 3 gets current info.

Legacy system using version 2 still works.

Historical queries can use historical versions.
Feature 4: Audit Logging

Complete compliance trail:

Audit Log:

2026-05-14 10:30:00 | RecommendationAgent | Retrieved | "Customer Preferences v2"

2026-05-14 10:30:15 | RecommendationAgent | Generated | "Recommendation 123"

2026-05-14 10:31:00 | UserNotificationAgent | Retrieved | "User Preferences"

2026-05-14 10:31:30 | UserNotificationAgent | Retrieved | "Marketing Policies"

2026-05-14 10:32:00 | AnalyticsAgent | Retrieved | "Sales Metrics (restricted)"

                                         ↑

                         Agent accessed restricted doc

                         System flagged as access denied

Query Audit Trail:

├─ Who accessed? RecommendationAgent

├─ When? 2026-05-14 10:30:00

├─ What did they access? Customer Preferences v2

├─ Which agent? ID: agent_456

├─ For which customer? Customer ID: cust_789

└─ Did they have permission? Yes (role: recommendation_engine)
Feature 5: Semantic Search

Find knowledge by meaning, not keywords:

Query: "How do we handle complaints?"

Traditional search matches:

├─ "complaint form" (keyword match)

├─ "complaints process" (keyword match)

└─ "customer complaints" (keyword match)

Semantic search understands meaning:

├─ "customer support escalation" (related meaning)

├─ "complaint resolution procedure" (related meaning)

├─ "unhappy customer handling" (semantic equivalent)

└─ "issue resolution framework" (underlying concept)

Returns more relevant results.

Finds knowledge agent wouldn't find with keywords.
Feature 6: Vector Embeddings

Store knowledge in a way that’s searchable and meaningful:

Document: "Our product is fast and reliable"

Traditional storage:

├─ Search for "fast": Found (keyword match)

├─ Search for "quick": Not found (different word)

└─ Search for "performance": Not found (synonym not used)

Vector embedding:

├─ Converts to vector: [0.23, -0.45, 0.89, ...]

├─ Search for "fast": Found (semantic similarity)

├─ Search for "quick": Found (semantic similarity)

└─ Search for "performance": Found (semantic similarity)

Agent searches for "How responsive is our product?"

System finds "Our product is fast and reliable"

Even though no exact words match.
Real Examples
Example 1: Customer Support
Customer support agent helps users:

Agent: CustomerSupportAgent

Permissions:

├─ View: Customer data, product docs, support policies

├─ Cannot: View financial data, employee records

└─ Data scope: Only assigned customers

Query: "User asks: 'How do I reset my password?'"

Agent retrieves:

  1. Search knowledge base: "password reset"

  2. Found documents (in order of relevance):

    • "Password Reset Procedure v5" (current)

    • "Troubleshooting: Can't Reset Password" (related)

    • "Security: Password Requirements" (related)

Agent uses documents to respond to user.

Audit trail:

├─ Time: 2026-05-14 14:32:00

├─ Agent: CustomerSupportAgent

├─ Documents accessed: 3

├─ Customer: cust_123

└─ Outcome: User helped with password reset

System tracks: For compliance, debugging, improvement

Example 2: Policy Enforcement
Recommendation agent must follow policies:

Agent: RecommendationAgent

Permissions:

├─ View: Product specs, customer preferences, pricing

├─ Cannot: View employee data, internal discussions

└─ Data scope: All products, assigned customer

Query: Agent generates recommendation

Knowledge retrieval:

  1. Product: "Widget v2"

    • Spec: €69.99

    • Availability: In stock

  1. Policy: "No recommendations for out-of-stock items"

    • Policy version: Current

    • Status: Active

    • Effect: Exclude out-of-stock

  1. Customer preferences: "Likes blue products"

    • Version: Current (updated yesterday)

    • Effect: Prioritize blue

Agent generates recommendation respecting:

├─ Product specs (accurate pricing)

├─ Policies (follows rules)

└─ User preferences (personalized)

If policy changes, next query uses new policy.

No code change needed.
Example 3: Historical Context
Agent needs context from the past:

Query: "Why did we stop using AWS?"

Retrieves:

  • Version 1 (Jan 2026): "AWS Evaluation: Good for scaling"

  • Version 2 (Mar 2026): "AWS Issues: Cost overruns"

  • Version 3 (May 2026): "AWS Decision: Switch to GCP"

With versions, agent can understand:

  • What we thought originally

  • What changed (cost overruns)

  • What decision we made (switch)

  • Why (cost)

Historical context enables better decisions.
Implementation: Setting Up Knowledge Management
Step 1: Create Tenant and Knowledge Base
from socratic_knowledge import KnowledgeManager

km = KnowledgeManager()

Create organization (tenant)

org = await km.create_organization(

name="Acme Corp",

id="org_123"

)

Create knowledge base for organization

kb = await km.create_knowledge_base(

organization_id="org_123",

name="Acme Knowledge Base"

)
Step 2: Define Roles and Permissions

Define role: Customer Support Agent

support_role = await km.create_role(

organization_id="org_123",

name="customer_support",

permissions={

    "view": ["customer_data", "product_docs", "support_policies"],

    "edit": ["support_tickets"],

    "cannot_view": ["financial_data", "employee_records"]

}

)

Assign role to agent

await km.assign_role(

agent_id="support_agent_1",

role_id="customer_support",

organization_id="org_123"

)
Step 3: Upload Documents

Upload document

doc = await kb.upload_document(

title="Password Reset Procedure",

content="...",

version="5.0",

access_level="public"

)

Upload sensitive document

sensitive = await kb.upload_document(

title="Employee Compensation",

content="...",

version="1.0",

access_level="restricted",

allowed_roles=["admin", "hr"]

)
Step 4: Agent Retrieves Knowledge

Agent searches with permissions enforced

results = await kb.search(

query="How do we handle customer complaints?",

agent_id="support_agent_1",  # Permissions checked

organization_id="org_123"     # Tenant isolated

)

Returns only documents agent has access to

for result in results:

print(f"- {result.title} (v{result.version})")


Automatically logged for audit trail

Step 5: View Audit Trail

Check who accessed what

audit = await km.get_audit_log(

organization_id="org_123",

document_id="doc_456",

time_range=(start_date, end_date)

)

for entry in audit:

print(f"{entry.timestamp}: {entry.agent_id} accessed {entry.document_id}")

The Philosophy: Knowledge Should Be Trustworthy
Agents are only as good as the knowledge they’re given.

Socratic-knowledge ensures knowledge is:

Accurate (versions ensure you know which version you’re using)
Appropriate (access control ensures agents only see what they should)
Traceable (audit logging ensures you know where decisions came from)
Secure (multi-tenancy ensures data stays isolated)
With trustworthy knowledge, agents make trustworthy decisions.
