Why people stick with it

Security that reduces worry, not adds work

Most site owners are not looking for another dashboard to babysit. They want fewer unknowns, plain answers, and protection that fits real workflows.

One place instead of five plugins

Firewall, login hardening, malware scanning, and vulnerability checks work together, so you are not piecing security together from half-finished tools.

Protected in minutes

The Install Wizard turns on sensible defaults fast. Go deeper later for scheduled scans, 2FA, or agency workflows when you are ready.

Findings you can act on

Plain-language results, fixable checks, event logs, and optional alerts. You see what happened and what to do next.

What you get

Four jobs. One plugin.

Protect traffic and logins, detect malware and risks, monitor what happens, and harden WordPress over time. Each piece has a clear job.

Monitor & alert

Track activity, schedule scans, and push alerts to Slack, Discord, or Zapier.

Harden & stay ahead

Run 50+ security tests, guided fixes, and keep improving without guesswork.

Know your WordPress core is clean

The Core Scanner compares your install to the official WordPress.org copies and flags unauthorized changes, infected files, and unexpected additions, so you can fix issues with confidence.

  • ✓ Compare core files to WordPress.org originals
  • ✓ Spot infected or modified files early
  • ✓ Catch unexpected additions in the install

Catch malware and risky plugins early

Scan for malware and check themes and plugins for known vulnerabilities and suspicious code, so you can fix problems before they become emergencies.

  • ✓ Malware and suspicious file detection
  • ✓ Theme and plugin vulnerability checks
  • ✓ Clear findings you can act on

Common questions

Is WordPress secure enough on its own?+

WordPress core is solid. Themes, plugins, and skipped updates are where most trouble starts. Extra protection helps you catch weak spots early and keep a clear checklist.

I only have a small site. Do I still need this?+

Yes. Automated scanners hit small sites the same as big ones. Good defaults, a firewall, and regular checks are usually enough, without making security a second job. See https://wpsecurityninja.com/why-is-insignificant-small-site-attacked-by-hackers/ and https://wpsecurityninja.com/do-i-need-a-wordpress-security-plugin/.

Where should I start if this feels overwhelming?+

Install, run the wizard, and follow the security tests. You get plain-language findings and next steps. Support and docs are there when something is unclear.

How do I activate my license key?+

Install and activate WP Security Ninja Premium, then enter your license key when prompted in the plugin. Need a walkthrough? See our Getting Started guide.

What’s the difference between free and premium?+

Free covers core security tests and essential protection. Premium adds cloud firewall, malware scanning, scheduled scans, stronger login protection, WooCommerce tools, and ongoing monitoring.

Can I use WP Security Ninja on multiple sites?+

Yes. Choose a single-site or multi-site plan based on how many WordPress installs you manage. Agencies get volume pricing.

Does WP Security Ninja slow down my website?+

It is built for real WordPress sites. Most scans run on demand or on a schedule rather than constantly in the background, so the performance impact is typically low. Details: https://wpsecurityninja.com/do-security-plugins-slow-down-wordpress/.

Will the firewall block legitimate visitors?+

It can happen on unusual traffic or custom setups. You can adjust firewall behavior, allow trusted IPs, and review false positives without turning protection off entirely.

Can I use it with another security plugin?+

Often yes, but stacking similar features (firewall, login protection, malware scanning) can overlap or conflict. In most cases, pick one clear stack unless you have a specific reason to combine tools.

Does it scan for malware?+

Yes. Premium includes a malware scanner that checks key parts of your site for suspicious code and known malware patterns so you can investigate flagged files early.

Does it check for vulnerable plugins and themes?+

Yes. Security Ninja checks installed plugins, themes, and WordPress itself against an up-to-date vulnerability database so you can patch known issues sooner.

Does it protect WooCommerce?+

Yes. Premium includes WooCommerce-specific protection for areas bots often abuse: login, registration, checkout, add-to-cart, and coupon abuse.

Do you offer support if I need help?+

Yes. Premium customers get support from the team behind WP Security Ninja. Real people who know the product and how it behaves on real sites.

Can agencies use it for client sites?+

Yes. Freelancers, agencies, and developers use Security Ninja across client portfolios with multi-site licensing, reusable settings, and agency-focused options.
