On October 16, 2026, Greece’s National Cybersecurity Authority highlighted a free web-based Microsoft 365 licensing comparison tool created by an independent CIO/CISO specialist. The tool helps organizations explore security functionality in the context of NIS2-related needs. The authority explicitly notes that an appropriate license does not by itself establish compliance.

Why compare Microsoft 365 license capabilities?

Organizations need to map security requirements to features available in the licenses they purchase. The tool referenced by the authority covers capabilities including multi-factor authentication, anti-phishing and malware protection, vulnerability management, access control and data protection.

Start with the risk assessment before comparing price plans.
Identify features included in each offering and those requiring separate licenses.
Verify current technical prerequisites against Microsoft’s official licensing documentation.

A license does not configure itself

Having a feature available is not the same as deploying it correctly. MFA, Conditional Access and data-protection controls require configuration, exception management, monitoring and ongoing operational ownership.

Confirm effective authentication protection for every relevant user.
Review privileged accounts, guest permissions and unmanaged device access.
Test policy outcomes, alerts, incident response and recovery procedures.

NIS2 requires more than a Microsoft tenant

NIS2 combines technical and organizational risk-management expectations for entities within its legal scope. Microsoft 365 covers only part of the environment. Governance, incident management, supply-chain risk, training and evidence of control effectiveness also matter.

Determine whether the organization falls within the applicable Greek NIS2 regime.
Document existing measures and control gaps before acquiring more licenses.
Maintain auditable records of policies, configuration decisions and reviews.

A practical starting point

Begin with a structured inventory of identities, endpoints, cloud services and administrator privileges. Review the Entra ID environment, then prioritize controls based on business impact. License optimization becomes a consequence of the target architecture rather than a substitute for it.

Define an MFA and access-control baseline.
Evaluate Intune device governance and other relevant security features.
Set a recurring review of incidents, alerts, user access and policy compliance.

Microsoft 365 environment review

Inventory Entra ID policies, user and application permissions, audit logs and exceptions. Pilot changes with a limited group, validate access impact and define a rollback path.

Implementation questions

Does this automatically affect our environment?

No. First verify whether the specific product, version and relevant configuration are deployed.

Is a security tool enough on its own?

No. Combine patching, restricted access, logging and tested backups.
