Frequently Asked Questions

Everything you need to know about C4 Modelizer Enterprise

Is my data really secure?

Absolutely. C4 Modelizer Enterprise was designed with security as a priority. Your data stays on the client side and is never stored in an external database without your explicit consent. SSO authentication ensures that only authorized people can access your models, and all communications are end-to-end encrypted.

How does SSO authentication work?

Our solution integrates with your existing identity provider (Google Workspace, Microsoft Azure AD, Okta, Auth0, etc.). Your users simply log in with their usual credentials, and all security policies you have configured (MFA, access restrictions, etc.) are automatically applied.

Can I import existing models?

Yes, C4 Modelizer Enterprise supports importing models in JSON format. If you have C4 diagrams created with other tools or with the open source version of C4 Modelizer, you can easily import them and continue working on them.

How does real-time collaboration work?

Our collaboration system allows multiple team members to work simultaneously on the same model. Changes are synchronized in real time, and each user can see who is working on what. You can also add comments and annotations to facilitate communication.

What is the difference with the open source version?

The Enterprise version adds SSO authentication, dedicated hosting, real-time collaboration, priority support, and other advanced features. The open source version remains available for free for individual use or for projects that do not need these additional features.

Can I try before buying?

Yes, we offer a 14-day free trial for all our plans. No credit card is required to start. You can explore all the features and decide if C4 Modelizer Enterprise meets your needs.
