All In One WP Security and Firewall
The Plugin All in one WP Security and Firewall is the best choice for WordPress website security. A hacked WordPress site can cause severe harm to your business, and it's reputation. Hackers can steal user data, passwords, implement malicious software, and can even spread malware to their users. If a user is serious about your website, then you need to pay attention to the WordPress security best practices. While WordPress core software is very much secure, and it’s audited regularly by hundreds of developers, there is a lot more can be done to keep your site protected by using a good security plugin.
I have used many security plugins like Cerber Security, Wordfence, but finally used All In One WP Security & Firewall. Because of its simplicity, essential Site Backup features and most importantly, I can manage this plugin with my limited security knowledge. Unknowingly wrong settings may block access to many functions on your website, and you will lose traffic.
