You are right it is difficult to keep self-managed installations secure vs. just using a SaaS provider, especially when some of the users only have basic admin skills. Having said that, we do our best to have secure settings by default, respond promptly to security issues (typically we release new images within hours of a new version being announced) and in particular in the case of WordPress we pre-configure everything out so automatic updates are enabled out of the box (which the user can also manage from the admin panel without touching the command line).
