    To me this is the best security plugin. There are many options (like easily block IP-addresses and countries) and it’s very easy to monitor what’s happening on the website. I also love the automatic scans and reports. The support is quick, friendly and helpful.

  • Our client’s review: CHECKLISTINSIDER.COM

    Our client’s review: CHECKLISTINSIDER.COM

    We continue sharing our clients’ reviews and today’s one is kindly brought to you by AK from checklistinsider.com on WordPress.

    Very useful plugin that helps you sit back and focus on other important tasks instead of dealing with those annoying spam user inputs from any and all the forms which are faced to public. So far I’m really happy with the performance of CleanTalk. It’s lightweight, performs its tasks perfectly well. Couldn’t expect anything more and don’t regret purchasing their anti-spam package.

    Another thing is their support. Had one minor issue with the plugin. Just had to raise a ticket and received pretty fast (within 24 hours) response from their technical engineer Serge. His proposed solution worked like charm.

    Hope to keep using it and never replace it for years to come.
