In a vast online world, blogging is a powerful tool for expressing various ideas. And while some blog out of enthusiasm and love, others have realized how to put it to good use when it comes to improving their brand or service. And what is the most popular web publishing software at the moment? WordPress, of course. The home to millions of bloggers from all around the globe mostly owes its popularity to the fact that it is open source. Last year, WordPress blogs had over 400 million monthly viewers, so just imagine the sheer potential for generating revenue. Blog owners are legitimately worried about whether their online property is safe and secure from different intruders, and who can blame them for that?
