Have it installed in my shop. The first feedback from the customers came after a short time. This makes it possible to improve the service. It works really well and can be integrated very easily. I can recommend it to anyone. Thanks for the great extension.

The extension does exactly what it needs to do (integrated with Joomla 2.5). Easy to install and configure. The support is excellent - very fast and friendly.

I am using for our e-commerce site, it works great.
After trying several things finally we are able to accept credit card payments.

Very easy to use

Best and fastest support I have ever seen

Good working plugin for PayU payment method for Turkiye

I use Kratos AntiSpam for 2 weeks already and i got not even 1 spam email or spam comment all this time. Must specify that before kratos, with a common captcha solutions my email box was always full on junks.

Highly recommend this extension !!!

For my blog and contact forms I was looking for an alternative for Re-captcha because its very annoying for my visitors to have to try to read these words and solve a puzzle before they can fill in a form or send a message. With this plugin all spam is blocked and the real comments are sent! Without anything changing on the frontend, brilliant

This component stopped all the spam from my site, the spam bot had taken over and it all stopped and the component saved my site.

I highly recommend this product.

My client has 8 different forms on his website, he was getting 12,000 emails a day from spammers, and demanding I fix it ASAP. I added a Re-captcha field to each form but it didn't work and he was still getting thousands of emails.

This product was very easy to install - took 2 minutes and it works - my client hasn't had one spammer email since.

I had also emailed the Support beforehand to make sure it was what I wanted and they had gotten back to me within 20 minutes.

Very happy.

Really not expensive for the services it provides.

Note also that the service alone is worth at least 10 stars. Fast, courteous and efficient. What more.

Joomla plugin, built to stop bots from sending spam through all website forms without requiring the user to enter captcha.

I had a bit of problem at first but an upgrade was quickly released on my support request and this allows for quick and easy setup.

Kratos really is THE solution to eliminate spam without having to ask the site vistors to enter complicated codes that difficult to read.

This extension should be installed on all Joomla sites. Do it before your site is attacked. Support is very responsive and this extension works as promised. You will receive a daily email from your site showing you the attacks that where blocked.

With Kratos, no longer necessary to install and activate other captcha plugins. Kratos is invisible to users. It works silently and super efficient. I definitely recommend Kratos for all sites wish to resolve a once and for all their problems with spam.
