If you run a business website, security is one of those things you keep meaning to “get to later” until you wake up to a weird redirect, a spammy popup, or customers emailing you saying your site looks… off.
And the frustrating part is that most basic attacks are boring. They are not movie hacking. It is automated bots scanning millions of sites for the same old weak spots. Outdated plugins. Weak logins. No firewall. No backups. That stuff.
So here are 5 free tools I consider must install for a typical WordPress business site. Not “nice to have”. More like, install them today, then get back to work.
1. Wordfence Security (Firewall, Malware Scan, Login Protection)
Wordfence adds a Web Application Firewall and malware scanner that blocks common attacks and alerts you when files or plugins look compromised. It also gives you strong login protection like brute force limiting and 2FA options, which is usually where bots start.
2. UpdraftPlus (Automated Backups, Easy Restore)
UpdraftPlus creates scheduled backups of your site so if something goes wrong you can restore fast instead of rebuilding from scratch. The free version covers the basics well and can save backups to places like Google Drive or Dropbox.
3. iThemes Security (Hardening, Security Checks, Lockouts)
iThemes Security helps harden WordPress by turning on practical protections like file change detection, user lockouts, and basic security tweaks you would not want to do manually. It is a solid “set it up once” plugin that closes a bunch of small doors attackers love.
4. Limit Login Attempts Reloaded (Brute Force Protection)
Limit Login Attempts Reloaded blocks repeated failed login attempts to stop brute force attacks from hammering your login page all day. It is lightweight, simple, and surprisingly effective for how often this exact attack happens.
5. WP Activity Log (User and Site Activity Monitoring)
WP Activity Log records important changes on your site like plugin installs, user logins, post edits, and settings changes so you can quickly see what happened and when. It is the fastest way to catch “Wait, who changed this?” moments before they turn into real damage.
