Data classification

Four tiers. One simple rule.

What data you’re working with determines what tools you can use - and whether you have a company enterprise seat determines how deep you can go. The one rule for everyone: customer and applicant information only ever goes into a company enterprise seat - never a free or personal AI tool. When in doubt, classify up.

Tier 1

Public

Information already public or intended for public release.

Examples
  • Marketing copy
  • Public website content
  • Generic equipment financing info
  • Industry research
Approved tools

Everyone: any free AI tool (with guardrails) - or a company enterprise seat

Tier 2

Internal

General internal information - no customer or applicant data, no financials, and nothing sensitive like pricing, underwriting, or security procedures.

Examples
  • Process documentation
  • Internal training materials
  • General templates (no customer details)
  • Meeting notes (no customer or financial details)
Approved tools

Any AI tool, with guardrails - free tools are fine for general internal work; a company seat works too

Tier 3

Confidential

Business-sensitive information - company financials and strategy, pricing and rates, underwriting or credit criteria, and security or wire procedures. No customer or applicant data.

Examples
  • Company financial projections
  • Rate sheets and pricing
  • Underwriting or credit criteria
  • Security and wire-transfer procedures
  • Strategic plans
Approved tools

Company enterprise seat holders only (Claude or Microsoft 365 Copilot) - zero-retention recommended

Tier 4

Restricted

Customer or applicant information - names, account details, SSNs, bank and payment info. Anything covered by GLBA. The high-stakes tier.

Examples
  • Customer or applicant names + account details
  • SSNs and bank info
  • Payment histories
  • EFA contracts tied to a real customer
  • A submitted application (it contains applicant financials)
Approved tools

Company enterprise seat holders only (Claude or Microsoft 365 Copilot) - zero-retention required, minimum necessary
