Permission sprawl
No one knows exactly who can access which SharePoints. Copilot shows it to everyone who asks.
HAFN KI-Revier Copilot is only as secure
The situation
Microsoft Copilot accesses everything a user has access to. An unmaintained permission landscape thus becomes a data-protection problem — and stays one as long as no one keeps the environment in good order for the long term.
Copilot is only as secure
as the environment beneath it.
The HAFN KI-Revier is not a product — it is a framework. We bring your tenant to the HAFN Standard, establish classifications and governance through Microsoft Purview, and through HAFN Betrieb (our managed service) we permanently ensure that data protection, security and data quality stay at this level. A secured environment that we define together — and keep in good order for you.
Familiar — and dangerous.
Sensitivity labels missing
Without labels, Copilot sees no difference between a press release and the payroll — and answers with both.
No governance concept
Who may use Copilot, with which data, in which context? Without an answer, no productive use.
THE APPROACH – THREE STEPS
Three steps
that make secure AI operation possible for the long term.
The HAFN KI-Revier combines three steps that build on each other — from one-off implementation through classification to permanent operation. No step is optional, none runs by itself.
Step 1 · Bring the tenant to the HAFN Standard
We harden your M365 tenant to the BSI-aligned HAFN Standard — Conditional Access, MFA, email security, permission clean-up, fully documented. Only on this basis is AI responsible.
Step 2 · Purview Information Protection
Sensitivity labels, DLP policies and a governance concept — in project mode, because the effort depends heavily on your data and processes. After that, Copilot understands the difference between a press release and the payroll.
Step 3 · Permanent operation through HAFN Betrieb
Through the Workplace service modules we keep your M365 platform permanently up to date in terms of data protection, security and data quality. Monthly reporting, ongoing governance monitoring, dedicated contacts. The environment stays in good order.
Three phases.
A permanently secure environment.
The three phases build on each other. Phase 3 is the goal — not a conclusion, but a permanent operating state.
HAFN Standard Workplace
We configure your tenant to the HAFN Standard — hardened, documented, Copilot-ready. Permissions, Conditional Access, email security, compliance settings. All traceable.
Microsoft Purview
Sensitivity labels, DLP policies, a governance concept — in project mode, because scope and effort depend heavily on your data and processes. Result: Copilot sees what is confidential — and abides by it.
HAFN Betrieb Workplace
We keep your environment in good order: data protection, security and data quality permanently up to date. Monthly reporting, governance monitoring, ongoing permission maintenance, enabling new use cases. Not one-off — permanent.
