  • Limited Official Support
    While community support is beneficial, there may be a lack of dedicated, official customer support for troubleshooting, compared to commercial software solutions.

    Open source software can be more vulnerable to exploits if not actively maintained and updated, especially if users delay applying patches or updates.
