1. At a glance

Draw.io (also branded "diagrams.net") is a web-based diagramming tool — comparable to Lucidchart or Visio. We host it ourselves so diagrams aren't dependent on a third party. Diagrams are typically saved to local storage, browser, or wherever we configure (often a shared MinIO bucket).

2. Business purpose

  • Architecture diagrams without a SaaS subscription.
  • Diagrams stay inside the company.

3. Audience

Internal staff.

4. Hosting & cloud infrastructure

5. Technology behind it

  • Type: off-the-shelf
  • Product: Draw.io / diagrams.net (open-source)
  • Stack: static-ish app (HTML+JS) served by Tomcat/Nginx; storage is delegated

6. Data it handles

  • Diagram files (XML / .drawio files). May include sensitive architecture detail — IPs, credentials in diagrams (which they shouldn't, but happens).

7. External dependencies

  • Storage backend (MinIO / WebDAV / browser-local).

8. Authentication & access

  • End-user login: Draw.io itself has no auth — the editor is open. Access control comes from the reverse proxy / Authentik in front.
  • MFA? depends on auth-proxy configuration.

9. Maturity assessment

10. Known risks & vulnerabilities

  • [CONFIRM] No built-in auth — anyone who can reach the URL can edit. Reverse-proxy auth or VPN-only access is required.
  • [INFO NEEDED] Diagrams leak architecture detail — sensitive IPs, hostnames, credentials sometimes drawn into diagrams.
  • [INFO NEEDED] Storage durability — if diagrams are saved to browser local-storage and not backed to MinIO, they're lost when the user clears cookies.

11. Impact if it goes down

None for operations; minor inconvenience for documentation.
