Best 20 Free WordPress Plugins for Security and Spam Protection

Hi!

In 2025, securing a WordPress site is no longer optional — it’s essential.

With WordPress now powering 43.4% of all websites on the internet.

It remains the largest target for hackers, malware, and spam attacks.

While the WordPress core is relatively stable.

96% of new vulnerabilities are discovered in plugins and themes rather than the core itself.

That means every additional plugin you install is a potential risk vector unless you guard against it.

In 2024 alone, researchers uncovered 7,966 new vulnerabilities across the WordPress ecosystem.

That’s roughly 22 new security issues every day.
