No matter what you use your website for, you need it to be running and healthy every hour of every day. However, like all digital assets, your website is vulnerable, which is why all software needs to be updated on a regular basis. Your computer is constantly updating your operating system (Windows, OSX, etc). Most of these updates are to improve security and stability. The software that runs your website is no exception. It too needs to be kept up to date with the latest security and functionality updates. You need a team that has years of WordPress website care and maintenance experience to keep things up to date.
