SiteLock Security – WP Hardening, Login Security & Malware Scans

🌟 Completely redesigned in Version 5.0 — now even stronger with 2FA in 5.1 🌟

The SiteLock WordPress plugin was recently rebuilt with three goals: make it faster, make it clearer and move the heavy work to the cloud. We built a cloudfirst architecture, modernized UI, expanded security controls and stripped out everything that didn’t need to be there. Our latest 5.1 release builds on that foundation with TwoFactor Authentication (2FA) to strengthen login security and give you tighter control over access.

The big changes:
– 🔒 Enhanced WordPress-specific hardening and login security controls
– ☁️ Cloud-powered scanning architecture for zero performance impact
– 🩺 New Site Health interface that shows you what matters in one view
– ⚡ Streamlined controls (fewer clicks to get protected)
– ✨ Modern codebase built for the WordPress you’re actually using today
– 🔢 Two-Factor Authentication (2FA) now available for stronger login protection

If you used the old plugin: this is a different tool. If you’re new: you’re starting with the cleanest, fastest version of the plugin.

Your website deserves protection that’s simple, fast and built for WordPress. SiteLock WordPress Security focuses on the everyday controls that matter most and helps you establish a secure baseline in minutes — WordPress-specific hardening, login protection with Two-Factor Authentication (2FA) and a clear Site Health dashboard that keeps you in control without slowing your site down. It’s lightweight, action-first protection that complements your host defenses: essential safeguards run inside WordPress while deeper checks happen securely in the SiteLock cloud. Skip heavy on-server scans and alert fatigue — run on-demand checks when you need extra assurance, so you can ship updates with confidence.

Security that grows with you

Our goal is straightforward: maintain a strong baseline with minimal overhead while giving you clear visibility and room to grow as your needs evolve.
And because security is never static, this plugin keeps pace. Two-Factor Authentication (2FA) is now available to strengthen login security with an extra layer of protection.

Can I Fix an Already-Infected Site with This Plugin?

The plugin focuses on prevention, posture and visibility — not full malware removal. It isn’t designed to fully clean up sites that were infected before it was active.
If your site is already compromised, act quickly, we recommend:

• Restoring from a clean backup if available
• Remove malicious files manually or with professional help
• For urgent assistance, consider SiteLock 911 – Emergency Malware Removal for rapid cleanup
• For ongoing defense, consider choosing a comprehensive SiteLock plan

Don’t Know Where To Start? Try This

Here are common first moves teams take with SiteLock. Order isn’t enforced — choose what fits your site and workflow:

• Enable WordPress hardening that matches your hosting and theme setup
• Turn on Login Security controls: brute-force lockouts, session timeouts, and password-hygiene prompts
• Connect a free SiteLock account, then use Scan Now to run an on-demand check after plugin/theme updates
• Review the Activity Log after major changes to spot unexpected admin/login events quickly
  Make one change at a time, validate and roll back any toggle that conflicts with your stack.
