Wordfence provides true endpoint security for your WordPress website. Unlike cloud based firewalls, Wordfence executes within the WordPress environment, giving it knowledge like whether the user is signed in, their identity and what access level they have. Wordfence uses the user’s access level in more than 80% of the firewall rules it uses to protect WordPress websites. Learn more about the Cloud WAF identity problem here. Additionally, cloud based firewalls can be bypassed, leaving your site exposed to attackers. Because Wordfence is an integral part of the endpoint (your WordPress website), it can’t be bypassed. Learn more about the Cloud WAF bypass problem here. To fully protect the investment you’ve made in your website you need to employ a defense in depth approach to security. Wordfence takes this approach.

Used Wordfence on ALL my WP sites since it came out
I would NOT ever start a site/blog without Wordfence being installed, configured and turned on! PERIOD. Even the free, basic version is a massive security safeguard which keeps my sites safe and sound, protecting my sites against both intruders and hackers that attempt to use bad plugins/themes to sneak in. It has saved my butt on many occasions over the past 6-7 yrs!
