No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    I don’t know where to start. A friend’s website had been hacked, was spewing spam and after hours of tech support with his host we were pressured to get into contracts to be able to remove the bots that got him locked out of his own email. Then, I searched for alternatives and found BitFire. What a difference! As it turns out, BitFire is highly advanced technology and far beyond what this little website needed, but I didn’t fully realize this until I contacted Cory Marsh, the developer of this genius product, and talked it out. AND, instead of turning me away with apologies and legitimate reasons why the typical BitFire install would be complete overkill, he talked me through how to use it, explained all the details and inner workings very patiently, cheerfully waiting on the line while I tried to grasp and respond to what was clearly over my pay grade, and then went ahead and removed the existing bots for me in the process. He used hours of his time trying to help me, and I am overwhelmingly grateful for his patience and incredible talent in developing this product. Cory is the real deal. I still can’t believe the help I received.

    This is an excellent plugin. Given that most recent attacks are from bots, focusing on bot protection makes perfect sense. We have been able to eliminate most malicious bots with it. We are deeply grateful to the plugin developer.

    Cory has gone above and beyond any plugin creator I have ever dealt with. He walked me through my own website and showed me things that I was not even aware of. We had a zoom meeting and he spent over an hour helping me. If I could give more than 5 stars I would. You will not be disappointed with this plugin. The Full Protection option is the way to go. Thank you so much Cory! This topic was modified 2 years, 8 months ago by findrarecoins. This topic was modified 2 years, 8 months ago by findrarecoins.

    Updated Review: BitFire Pro is the best I know for WordPress – no doubt. In my earlier tests, it (the free version) defeated WordFence Pro and all the other WAF plugins. With the 4.0 version update, the WAF which was present in the free version just disappeared and became part of the Pro version. As for the RASP, it is again a Pro feature and that was the case earlier too – RASP is a great Pro feature that a serious person would upgrade to. I tested the latest free version(4.0) and found it to be not qualified to be on my WP stack anymore as it doesn’t have WAF as it did before. I do know that BitFire “Pro” is good and much better than the WordFence Pro, so I don’t want to take away the 5-star rating from my review – this is my gratitude for your hard work, you absolutely deserve it. Any day I would suggest anybody use the BitFire Pro version in any of their serious web projects – it really works great! Anyways, BitFire free version isn’t for me. Good wishes.

    I don’t know much about security but the creator of this plugin Cory does. He personally gave me tips and he configured my settings and actually taught me about hacks and bots and stuff and he showed me how Bitfire protects me from hacks.

    I woke up yesterday to a hacked website which kept redirecting me to a spam site. I couldn’t log in or anything. I found a youtube video about BitFire and contacted them. They got right back to me, installed the software directly on my server, found the malware, cleaned it and then spent almost an hour on the phone talking me through my web site security and even gave me some pointers about my page load time. crazy! super nice guy. Highly recommend contacting them and using their malware scanner.
