Wordfence is a firewall security plugin that protects your website from getting hacked by identifying malicious traffic and blocking attackers before they can access it. Wordfence continuously analyzes the latest threats and updates itself with the newest firewall rules, malware signatures, and malicious IP addresses it needs to keep your website safe.
There is a free version with limited capabilities, but we recommend the Premium version since it offers the needed features. Firewall rules and malware signatures are delayed by 30 days with the Wordfence Free edition.
