2. Why “best free security plugin for WordPress” matters

WordPress is the most widely used CMS in the world, and that popularity makes it a prime target for hackers. According to industry sources, free security solutions can still provide solid protection:

  • The plugin Wordfence Security is noted as “one of the more impressive free security solutions” offering firewall blocks, brute-force protection, malware scanning.
  • Free security plugins help by providing: malware scanning & removal; firewall/traffic filtering; login hardening; user activity monitoring

Yet many free plugins have limitations (e.g., delayed signature updates, slower scans, less coverage). So selecting the best free plugin means balancing features + reliability.
