Wordfence Security is a security plugin. It includes a firewall, anti-virus scanning, cellphone sign-in (two factor authentication), and malicious URL scanning. Wordfence is the only WordPress security plugin that can verify and repair your core, theme and plugin files, even if you don’t have backups. Doesn’t that sound magical? I think it does.
I chose the Wordfence plugin because if I am using my WordPress blog as a Content Management System (CMS) for selling items, it will be entirely important that I make the page secure. I would do further research to find out just how secure it is if I intend on implementing it into my e-commerce site. I will read more on the subject when it gets closer to me posting my real ecommerce site and I’m sure all will be different when the time comes. But if I were at that point now, I’d install this plugin to have some sense of security.
