Manier times clients ask me that can wordpress websites be hacked ? If i talk about the Informational websites, i see there is no payment gateway involved, neither it is a top notch Multi national company website which any body intent to hack still clients worry about hacking. They are unaware of the fact that a huge percentage of the websites in India are made up of wordpress. WordPress is used among 178+ countries. The comparision with WordPress vs CMS free website is totally a different thing, they have their own pros and cons. But as far as hacking is concerned, websites made up of wordpress is very safe, infact many ecommerce websites are on wordpress and they are running successfully without hack since years. Among all e commerce website around 20-35% are made up of wordpress. So people generally have irrelevant worry about safety which should not be considered in the case of wordpress website.
