Short answer: Absolutely! Very similar to updates your phones, tablets, and computers need...websites powered by WordPress as well as its themes and plugins need the same type of updates for enhanced improvements to functionality, security, and performance. While some updates are more regular than others, security updates can happen quickly to correct a very serious issue with your site. Outside of the security patches (which are pretty frequent), the level of proactive care your site requires depends on:
Number of plugins installed on your WordPress website. The more plugins your site uses for the functionality you need could increase the number of security patches that need to be applied. Types of plugins you are using on your WordPress website. Typically, premium/paid plugins are more proactively maintained and built with higher quality code so they generally require fewer updates. The typical WordPress website has about 15 plugins, on average. Our site is utilizing 29 plugins, 25 of them are premium/paid plugins. During the three years have provided proactive care services for our over 80 WordPress website owners, and we have never experienced a hacked website.
