Wordfence is a security plugin that will protect your WordPress website against hacks, cyber attacks, and online security threats. They offer both a free plugin and a $39 per year premium version. Both options continually scan your site for known malware, bad URLs, outdated themes and plugin files, backdoors and hackers, fake google bots and more. The premium version also offers country blocking, where you can choose in your account settings to block entire countries from accessing your site and login form. This is especially useful for those of you whose customers are US or US and Canada only, as all others can be manually blocked which will prevent a multitude of potential content theft, attacks and other malicious activity from those regions.
