Enterprise & IT Governance

Deployment & Security Specification

Karo instruments are built for multidisciplinary enterprise BIM workflows. Review technical architecture parameters, data privacy boundaries, and IT deployment standards below.

01100% On-Premise

Local Execution & Model Privacy

Geometry analysis, link comparisons, and diagnostics execute strictly within the local Autodesk Revit memory space.

  • Zero transmission of BIM geometry, coordinates, or proprietary parameters to external clouds.
  • Diff databases and audit logs are stored in local, encrypted SQLite files on the workstation or office LAN.
  • Strict data isolation suitable for NDA-governed government, defense, and healthcare projects.
02Silent MSI / GPO

Centralized IT Deployment

Enterprise installation packages built for automated, zero-touch deployment across distributed BIM teams.

  • Standard MSI / EXE installers supporting silent CLI flags (/quiet, /qn, /norestart).
  • Ready for Microsoft Intune, SCCM, PDQ Deploy, and Active Directory Group Policy (GPO).
  • Standard Autodesk Revit .addin manifest registration without invasive system modifications.
03Air-Gapped Ready

Offline & Air-Gapped Resilience

Designed for high-security corporate perimeters, restricted VPNs, and offline drafting environments.

  • No continuous cloud heartbeat required during active Revit modeling and drafting sessions.
  • Cached license validation ensures work continues uninterrupted during travel or network dropouts.
  • Shared policy syncs through standard UNC network paths without external dependencies.
04Revit 2023–2027+

Host Session Isolation & Stability

Engineered against official Autodesk Revit .NET APIs with strict defensive exception handling.

  • Native 64-bit architecture certified for Windows 10 & Windows 11 x64 enterprise environments.
  • Defensive try-catch sandboxing ensures tool exceptions never crash the host Autodesk Revit session.
  • Full worksharing and Revit Cloud Worksharing (ACC / BIM 360) synchronization compatibility.
