Short answer
What should organizations review under the EU AI Act when choosing enterprise AI platforms?
The EU AI Act does not make one enterprise AI platform automatically compliant for every organization. Obligations depend on role and use case. Since 2 August 2026, further transparency and enforcement rules apply, while some high-risk use cases follow different transition timelines. Platform features for roles, approvals, logs and data access can support governance but do not replace risk classification or organizational responsibility. [75][76][22][18][12][13][25][31][03]

Evaluation criteria
4 criteria to evaluate separately
Governance
Evaluate roles, permissions, approvals, audit logs and organizational responsibilities in the concrete deployment.
Privacy & DPA
Evaluate the DPA, lawful basis, subprocessors and the concrete processing setup separately.
Hosting and data region
Do not treat storage region, processing region, model region and possible third-country transfers as the same commitment.
Model training
Verify contractually and technically whether prompts, outputs or company data may be used for model training.

How do the documented offers differ?
| Criterion | ChatGPT Enterprise | nuwacom | Microsoft 365 Copilot | Langdock |
|---|---|---|---|---|
| Governance | ChatGPT Enterprise: workspace and compliance controls. [22][18] Governance is not absent by default. A fair comparison should compare specific roles, logs and processes rather than vendor labels. | nuwacom: central control of models, access, rules and actions. [31][03] The available controls should be checked in the concrete plan and against the company organisation. | Microsoft 365 Copilot: policy controls in the Microsoft environment. [25] Protection follows the actual permissions. Over-broad source access is not automatically fixed by AI. | Langdock: workspace control and agent governance. [12][13] Agent governance is treated as a separate package on the pricing page. Scope and future cost should be checked separately. |
| Administration | ChatGPT Enterprise: SAML SSO and SCIM. [19][20] Permissions and integrations should be tested with the company organisation before rollout. | nuwacom: roles, SSO, MFA and central Workspace administration. [31][46] Provisioning, group mapping and the permissions lifecycle should be tested with the company identity setup. | Microsoft 365 Copilot: Microsoft administration. [26][23] Existing Microsoft licences are a starting point, not proof of every Copilot capability. | Langdock: SSO, SCIM and SAML documented. [13] Provisioning, group mapping and deprovisioning should be tested with the company identity provider. |
| Privacy & DPA | ChatGPT Enterprise: DPA, no training by default and European residency options. [20][21] Data residency and inference residency have defined scope. Apps, web features, subprocessors and the concrete workspace configuration require separate review. | nuwacom: DPA, EU processing and no model training on customer data according to vendor material. [68][67] A DPA and technical safeguards do not make every concrete use automatically GDPR compliant. Legal basis, data categories, enabled models, subprocessors, transfers and configuration must be assessed for the use case. | Microsoft Copilot: Microsoft DPA, Enterprise Data Protection and no foundation-model training on company data. [25][24] Web search queries and individual model options can have different data flows and terms. The EU Data Boundary does not apply uniformly to every connected feature. | Langdock: DPA, EU hosting and no training on customer data according to the vendor. [12] Not every model is automatically hosted in the EU. Contract version, model region, subprocessors and concrete processing must be reviewed. |
| Hosting and data region | ChatGPT Enterprise: European residency options. [21] The region covers the EEA and Switzerland. Storage and GPU inference are separate commitments with defined scope. This is not a blanket promise that everything stays in Germany. | nuwacom: Azure EU, German IONOS and StackIT options, plus BYOC. [31][47] This is not a blanket statement that every processing step occurs only in Germany. Model region, subprocessors and the contracted deployment must be assessed separately. | Microsoft 365 Copilot: EU commitments with exceptions. [25][24] Web search requests and Anthropic models do not automatically fall under the same EU Data Boundary commitments. Germany-only hosting is not established by this source. | Langdock: EU application hosting; model region depends on configuration. [12] This does not mean every model is hosted in the EU. Dedicated and on-premise options have separate conditions. |

Which EU AI Act rules are already relevant in 2026?
The AI Act became generally applicable on 2 August 2026, while some obligations started earlier and certain high-risk rules have later transition dates. Organizations should therefore review the concrete use case and applicable timeline rather than use a single compliance date. [75]
Decision guide · Decision context
Why is a vendor AI Act label not enough?
Obligations depend in part on the role an organization takes in the AI value chain and on how the system is used. An enterprise workspace can provide technical controls, but internal risk classification, processes, ownership and documentation remain organization-specific. [75]
Decision guide · Decision context
Which transparency duties apply to AI systems?
Since 2 August 2026, Article 50 includes transparency obligations for certain AI interactions and generated or altered content. Whether and how these duties apply depends on the concrete system and use case. [76]

Which platform capabilities can support AI governance?
For platform selection, roles, permissions, model approvals, audit logs and controlled data access are particularly relevant. All four compared platforms document governance or administration capabilities, with different emphasis. [22][18][12][13][25][31][03][19][20][26][23][46]
ChatGPT Enterprise provides access and feature controls plus Compliance API capabilities for traceability, according to OpenAI. [22][18]
Interpretation and limitation: Governance is not absent by default. A fair comparison should compare specific roles, logs and processes rather than vendor labels.

ChatGPT Enterprise supports SAML SSO and automated user management through SCIM, according to OpenAI. [19][20]
Interpretation and limitation: Permissions and integrations should be tested with the company organisation before rollout.
Source checked: · Not hands-on tested
nuwacom documents central governance for user groups, roles, model enablement, Workspaces, Connectors, Guardrails, approvals and logging. [31][03]

Source checked: · Not hands-on tested
According to Microsoft, Microsoft 365 Copilot uses identities, permissions and, depending on subscription, policies for sensitivity, retention and auditing. [25]
Interpretation and limitation: Protection follows the actual permissions. Over-broad source access is not automatically fixed by AI.
Source checked: · Not hands-on tested
Microsoft 365 Copilot is managed through licence assignment and Copilot administration settings in the Microsoft environment. [26][23]

Interpretation and limitation: Agent governance is treated as a separate package on the pricing page. Scope and future cost should be checked separately.
Source checked: · Not hands-on tested
Langdock lists SSO, SCIM and SAML in its Business offer. [13]
Interpretation and limitation: Provisioning, group mapping and deprovisioning should be tested with the company identity provider.

Which questions belong in procurement under the EU AI Act?
Procurement should document technical platform features separately from organizational obligations. A vendor feature is useful only if it fits the organization's concrete process, roles and risk classification. [75]
- Document the organization role and concrete AI use case.
- Review risk classification and applicable timelines.
- Assess transparency and labelling duties for the use case.
- Test roles, approvals, audit logs and data access in practice.
- Document contractual evidence and responsibilities.
- Continue a separate GDPR review where personal data is processed.
