Proven in the housing sector
We have housing companies and cooperatives among our existing customers. The requirements — from tenant-data protection to acquisitions of smaller companies — we know from practice.
Industries · Housing sector
WHETHER 500 OR 5,000 RESIDENTIAL UNITS —
YOUR IT SHOULD BE AS RELIABLE
AS YOUR TENANCY AGREEMENTS.
Heterogeneous landscapes from acquisitions, regulatory pressure on tenant data, lean IT teams — we know the housing sector. HAFN Standard creates the BSI-aligned cloud basis. HAFN Betrieb maintains it for the long term.
WHAT YOU CAN BUILD ON.
BSI-aligned
The standard configuration is designed for common audits: BSI baseline protection, GDPR, ISO 27001. You present, instead of reconstructing.
Fixed price instead of day rate
HAFN Standard at a fixed price, HAFN Betrieb as a monthly flat fee. Predictable for the board, the head office and supervisory bodies.
Microsoft Solutions Partner
Modern Work, Security, Infrastructure Azure and Digital & App Innovation Azure. Azure Infrastructure Migration specialisation — for clean tenant consolidations.
REGULATED, HETEROGENEOUS
AND WITHOUT OWN IT.
Six typical pain points we see in the housing sector — and that disappear with a clean Microsoft 365 standard, instead of being passed on.
Heterogeneous IT landscape
Acquisitions of smaller companies bring decentralised structures — each company with its own IT history, its own permissions, its own sprawl.
Regulatory pressure
GDPR, BSI baseline protection, data protection for tenant data. Compliance is not optional, and the evidence often sits only in one person's head.
Tenant data especially worth protecting
Social data, family circumstances, tenancy histories, debtor information. Data breaches here hit not only compliance, but directly the trust of tenants.
Tenant portals and digital administration
Increasing digitalisation of communication requires a stable cloud basis — not a makeshift solution between ERP, tenant portal and SharePoint.
Missing in-house IT expertise
Outsourced IT responsibility is the norm. But not every external IT provider understands the housing sector, property management or the industry's ERP specifics.
AI is coming — but the basis is missing
Copilot can summarise tenancy agreements, sort complaints, prepare dunning histories. But only on a data basis with clean permissions — otherwise Copilot sees files no one should see.
FOUNDATION FIRST,
THEN DIGITALISATION.
HAFN Standard creates the BSI-aligned, GDPR-compliant basis. HAFN Betrieb maintains it — and enables tenant-portal integration, Copilot use and compliance reporting without ongoing effort.
HAFN STANDARD WORKPLACE
Tenant, identities, devices, permissions — brought to a documented, BSI-aligned configuration. Tenant data in sensitivity-label-protected areas, a clear separation between head office and property management, audit-ready.
HAFN BETRIEB WORKPLACE
We take over ongoing operation with modular service modules — Tenant Administration, Managed Workplace, Backup, Workplace Governance. Monthly reporting for the board and supervisory bodies that is understandable even without an IT background.
Industry levers
THREE BUILDING BLOCKS
THE HOUSING SECTOR NEEDS.
A generic M365 standard is not enough — the housing sector has its own requirements from BSI, GDPR and the sensitivity of tenant data. We bring three industry-specific building blocks.
BSI-aligned configuration
The HAFN Standard configuration for the housing sector follows BSI baseline-protection recommendations — Conditional Access, device compliance, backup, logging. Audit evidence arises from ongoing operation.
Tenant-data protection with sensitivity labels
Social data, tenancy histories and debtor files are marked with sensitivity labels — protected from oversharing, anonymous links and unintended AI access.
Compliance reporting for the board
Monthly reporting on permission, device and tenant-data status — understandable for the board, the supervisory board and the data protection officer. Not a collection of raw SIEM logs.
WHAT HAFN MEANS FOR
THE HOUSING SECTOR
IN CONCRETE TERMS.
BSI compliance without ongoing effort
Workplace Governance continuously monitors whether your environment complies with the defined data-protection policies. Oversharing, orphaned guest accounts and anonymous links are detected before they become a problem.
Scalable as the portfolio grows
New companies and sites are integrated to the same standard — no special projects per acquisition. As the portfolio grows, HAFN Betrieb grows with it.
Tenant portals stably integrated
Interfaces to tenant portals, ERP systems and SharePoint content are documented and maintained. Not a makeshift solution between four systems, but a controlled integration layer.
Workplace Governance for tenant data
Sensitive files are automatically classified, protected from oversharing and shielded from unintended AI access. The data protection officer gets the evidence they need.
Cross-site
Head office, property management, branch offices — all work in the same environment, with the same security rules, with the same permissions. Consolidated IT instead of parallel worlds.
Dedicated contacts
No ticket system, no anonymous hotline. Your HAFN team knows your company, your tenant structure and your compliance requirements — and takes responsibility.

Frequently asked questions
EVERYTHING POINTS TO HAFN,
BUT …?
What does "BSI-aligned" mean in concrete terms?
The standard configuration follows the recommendations of BSI baseline protection for Microsoft 365 and Azure — Conditional Access, device compliance, backup strategy, logging. The evidence is documented and audit-ready. We do not issue a BSI certification ourselves — we provide the basis for it.
We have several companies — how do we integrate them?
In a standardised way. Each company is set up to the same HAFN Standard — either in a consolidated tenant or with clear separations. Which path fits we clarify in the first conversation, depending on compliance and tax requirements.
How exactly is the protection of tenant data ensured?
Through sensitivity labels, Conditional Access and Workplace Governance. Tenant files are classified, access is restricted to authorised roles, oversharing is detected. With AI use, the labels take effect — Copilot sees only what the sensitivity classification permits.
We have our own ERP for property management — does it stay?
Yes. HAFN Standard and HAFN Betrieb build the Microsoft 365 workplace around your ERP. Interfaces, permissions and data flows are documented, the ERP remains untouched. Where needed, we cleanly bring it into identity and access management.
Can we cancel monthly?
Yes. All HAFN Betrieb service modules can be cancelled monthly. If your needs change — consolidation, growth, new compliance requirements — we adjust the service package easily.
