Wordfence Security Original (FREE)

Firewall & Security Scanner, the most commonly used plugin. 
In order to secure WordPress, Wordfence requires an endpoint firewall and a malware scanner designed from the ground up. To keep your website secure, our Threat Protection Feed weapons Wordfence with the newest firewall laws, malware signatures and malicious IP addresses it requires. The most robust WordPress protection solution available, rounded out by 2FA and a suite of additional features, is Wordfence.
