Plone has the foundation to support great customization through add-ons, version control, open source software, and easily modifiable permissions.

1. Thanks God! It's open source. We (Vietnamese) are still in process of development period, we would consider prefer to use open source software/platform than rather than other because of First - save cost, Second - freely to build your own world (not just Hello World :D). Besides, Plone CMS having a strong community allow developer to share knowledge and experiences, help each other hands-on and so on, bring more value/feedback to Plone development team. 2. CMS core workflow with deep customization enabler allow developer freely to custom and build on it. 3. Flexible permission management & customization allow developer to tailor business needs more accurately 4. Wide range of categories that would freely to build CMS-based/Web-portal or web application to meet customer requirements 5.Security management also best. In my opinion, it's most secure CMS

scalability; cms in user use is friendly;
