Nowadays, companies are increasingly using open source free content management systems (WordPress, Joomla, etc.) to build their own corporate website. The decision is most often based on the fact that the frameworks can be used for free and the functionality of the page can be expanded with millions of plug-ins, so the pages can be created quickly and cost-effectively.
However, most companies forget an important step, to make a contract with the website developer or operator for these websites. After missing this step, most websites will become homeless and vulnerable due to open source.
