الأسئلة المتكررّة

Who is this plugin for?

For anyone who wants to make their site more secure and prevent downtime due to hackers

Will this plugin slow my site down?

Absolutely not. You may experience a slight slow down while tests are being run but that takes less than a minute.

Will it work on my theme?

Sure! Security Ninja works with all themes.

What changes will Security Ninja make to my site?

None! Security Ninja will just give you the test results and suggest corrective measures with precise instruction. It will not make any changes to your site.

Is this plugin safe to use?

Of course. It’s a reporting-only tool. It doesn’t make any changes to your site.

Is this plugin legal to use?

Yes. It’s your site you can do whatever you want with it. Running tests on other people’s sites is illegal but Security Ninja can only perform tests on the WordPress page it’s installed on.

It’s not working!!! Arrrrrrrrr

We did our very best to make Security Ninja compatible with all plugins and themes, but problems can still happen.

For me this plugin does what it is supposed to do. Really helps me keep my WordPress safe and up-to-date.

... but Support is even much better! Namely, I had one license issue/question which I was pretty sure it won't be possible solving it. But Support did all in their powers (and more!) to solve our request, and at the end - they really did it (and it was also during the weekend). Amazing!
