Wordfence 

Wordfence Premium.

Wordfence Premium provides the real-time endpoint protection you need to protect your mission-critical website. Wordfence includes an endpoint firewall and malware scanner that were developed from the ground up to protect WordPress. Our Threat Defense Feed equips Wordfence with the latest firewall rules, malware signatures, and malicious IP addresses you need to keep your site secure. Complete with a suite of additional features, Wordfence is the most comprehensive security option available.

Wordfence runs on the terminal, your server, providing better protection than cloud alternatives. Cloud firewalls can be circumvented and have historically suffered from data breaches. The Wordfence firewall leverages user identity information in over 85% of our firewall rules, something cloud firewalls don't have access to. And our firewall doesn't have to break end-to-end encryption like cloud solutions.
