Yes, but please bear in mind that maintenance of a software package is an ongoing responsibility. If you are installing a software package then you need to periodically check for patches and new versions and have a regular update schedule. The most frequent cause of web site defacements is unpatched software with known security vulnerabilities. If you are installing homegrown software consider who will fix it in a year, or two, when a flaw is discovered or some incompatibility with the latest version of server software causes it to not work. We cannot undertake to fix user installed software that stops working when we install a necessary server software update.
