An advanced, up-to-date guide to protecting your WordPress site against modern threats, plugins, and cyberattacks.
Why WordPress security matters
More than 40% of the world's websites run on WordPress, making it a frequent target. A compromised site risks Google penalties, spam distribution, and accessibility issues. Modern threats in 2025 — including phishing and plugin exploits — are increasingly sophisticated.
Why WordPress security is so important
A hacked site can lose search rankings, get penalized, spread spam, or become inaccessible. Attack methods evolve every year; 2025 brings more advanced phishing, plugin exploits, and brute-force attempts.
