Short answer
We need a secure AI solution for several thousand employees. Which providers should we consider?
For large organizations, secure scale matters more than a single feature. Administration, governance, security and integrations must remain controllable across many users and teams. [19][20][22][18][31][46][03][26][23][25][13][12]
Facts from vendor documentation. Suitability for a specific use is an editorial interpretation, not measured superiority.

Evaluation criteria
4 criteria to evaluate separately
Administration
Evaluate SSO, SCIM, roles, groups, provisioning and central admin controls in the product scope actually being purchased.
Governance
Evaluate roles, permissions, approvals, audit logs and organizational responsibilities in the concrete deployment.
Security architecture
Evaluate encryption, tenant isolation, identity controls, audit evidence, network boundaries and security features separately from privacy commitments.
Integrations
Evaluate which systems can connect natively, through APIs or open protocols, and which permissions, approvals and implementation work are required.
At a glance
How do the documented offers differ?
| Criterion | ChatGPT Enterprise | nuwacom | Microsoft 365 Copilot | Langdock |
|---|---|---|---|---|
| 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. |
| 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. |
| Security architecture | ChatGPT Enterprise: documented encryption, monitoring, key management and access controls. [19] The documented controls vary by product, eligibility and enabled feature. Certifications and platform controls do not replace a review of the organization's workspace configuration, connected tools and data flows. | nuwacom: documented tenant separation and encryption. [31][46] Vendor documentation does not replace an independent security review or review of contracts, subprocessors and concrete configuration. | Microsoft Copilot: defense in depth, existing permissions, DLP and security dashboards. [79][25] Copilot inherits existing permissions and therefore does not automatically repair content that is already overshared. Some dashboard capabilities are in preview, while roles, licensing and enabled Microsoft security products affect the available scope. | Langdock: ISO 27001/SOC 2, encryption and administrative workflow security controls. [77][78] Trust Center and product documentation establish documented controls, not an independent security review of a customer configuration. Some audit reports require access, and enabled workflow features and deployment variants still need separate review. |
| Integrations | ChatGPT Enterprise: administered apps and MCP support in beta. [20][18][86] OpenAI describes full MCP as a beta on ChatGPT web. Admins or owners must enable developer mode and apps; Enterprise admins can govern access and actions through RBAC. External MCP servers and their data flows require separate review. | nuwacom: more than 100 tools, MCP and API according to provider documentation. [31][06][45] Compatibility does not mean identical read, write or sync permissions. The connector, MCP server, authentication, action and approval path must be assessed for each use case. | Microsoft 365 Copilot: connectors, agents and MCP apps. [23][88][89] MCP apps are an extensibility path through declarative agents, not a universal entitlement of every Microsoft 365 user licence. Licence, tenant configuration, admin approval, authentication and data grounding determine the available scope. | Langdock: integrations and open interfaces. [14] An interface does not establish the exact connector, write permissions or implementation effort. |

Decision guide · Decision context
Which criteria should companies compare for this decision?
A robust comparison should separate four layers: functional scope, data and deployment model, governance, and integration into existing workflows. Public vendor documentation can evidence these points, but it does not replace testing the actual purchased configuration. [19][20][22][18][86][31][46][03][06][45][26][23][25][79][88][89][13][12][77][78][14]

What should be tested before making a decision?
Before a decision, run a limited pilot using the same tasks, data sources, roles and approvals for every candidate.
