Fantastic and desperately needed


So...I’m a whistleblower in corrupt South Texas. For the past five years, I have been the target of sustained, organized criminal hacking. I have a graveyard of computers in my attic. I have spent thousands of dollars on cyber security that always seemed to get breached by dedicated crackers. It’s been a nightmare. Apple has been slow to admit that criminal hackers have various ways to exploit vulnerabilities in Apple devices so when I read about Cujo, I decided I had nothing to lose. The device itself is very impressive and does exactly what it says it will do: it fights off attacks on and attempts to enter my network through the modem/router 24/7. And that’s no mean feat as crackers act like their freedom depends on them making sure they have control of my devices and communications (which, of course, it does). At any rate, organized attacks and exploits are occurring every 1-2 minutes and Cujo appears to catch them all. For the first time in a long time, I feel in control of my own network. Likewise, the customer support can’t be beat. Knowledgeable, polite, willing to do what it takes to get your network secured by Cujo. It’s very clear the techs understand the threats out there and are confident in Cujo’s ability to fight them. I couldn’t be happier with Cujo. Well done.

Great Product (Suggested Enhancements Though)


I'll start by saying that this product is great. It does exactly what it advertises however it may be too sensitive and therefore notified on several instances where it could otherwise be silent. Today alone I've received north of 15 notifications. To clear the app badge on my phone I have to go in there and read each, one at a time when most of them are threats based on advertisements nested in web pages. Instead you should be able to clear them by either swiping and selecting delete or selecting an edit button and then checking off which ones to mark as read and/or delete. When going into the app you should also be able to notify based on criticality vs. every incident type. Also be able to set a default view of your preferences around app configuration as well as adding more depth to notification options. On a scale of 1-10 I give the app a 7 around maturity. Well executed so far but has a way to go.

Excellent Product If Foreign Gov. Hackers Aren’t Already In Your Devices


Having lived with 8 years of cyber terrorism and begging for help from the obvious American Agencies, most definitely in the know, I learned that there are no cyber experts and we are 110% responsible for our own protection. Hence, artificial intelligence made sense to me, and the support staff most excellent and truly understanding of the cyber nightmares most have not yet experienced. Unfortunately, my cyber terrorists are government sponsored and incredibly superb in cyber raping and terror, thus they can circumvent even the toughest encryption and security, but as a survivor I still will not give-up on doing the absolute best I can. Thus, I am incredibly impressed by CUJO simply because it does stop more than the mainstream internet provider in America and again, the staff is shocked by nothing!!!!
