HCL Domino vs Microsoft 365 — NIS2 Compliance Comparison for District Offices

District offices, classified as essential entities under NIS2, must meet new, rigorous information security requirements. In this context, choosing a collaboration platform becomes a strategic decision that impacts compliance, security, and operational costs.

Key Differences: Domino vs Microsoft 365

Both solutions offer collaboration toolsets, but differ significantly in their approach to security, data sovereignty, and licensing models. For district offices that must be fully NIS2-compliant, these differences can be decisive.

Data Sovereignty

HCL Domino

HCL Domino offers full data sovereignty. Organizations can deploy on-premise, in private cloud, or in sovereign cloud. HCL Technologies, as an Indian company, is not subject to US regulations such as CLOUD Act or FISA 702.

Microsoft 365

Microsoft 365 operates on Microsoft's global infrastructure spread across data centers worldwide. Even if data is stored in the EU, Microsoft (a US company) is subject to CLOUD Act and can be forced to disclose data in response to US government requests.

Security and Encryption

Both HCL Domino and Microsoft 365 offer end-to-end encryption, but differ in key control. In Domino, organizations store keys in their own infrastructure. In Microsoft 365, Microsoft-managed keys can be shared with other Microsoft services.

NIS2 Compliance

NIS2 requires that organizations can control their security infrastructure and be fully prepared for incidents. Domino, through on-premise deployment, enables full control. Microsoft 365 requires trusting Microsoft's security controls.

Recommendations for District Offices

For district offices that must meet NIS2 requirements and prefer full data sovereignty, HCL Domino appears to be the better choice. It offers full control over infrastructure, data, and encryption keys, which is critical for compliance with Polish law and the NIS2 directive.
