Customer Reviews

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.

Current App Issue

First of all, Cujo works very well. However, the new app that came out just a few days ago, no longer gives any threat notifications. I’m hoping that Cujo is still active and it’s just an app issue. Everything on the app says life is fine, just no longer see any threat notifications anymore like I used to get daily. With it protecting 29 devices, there would always be something daily it would block. Maybe it still is, however don’t know anymore? Please fix the app!

The best smart firewall for consumers in market

After three months using the Cujo firewall it have detected over 60 security threats and risks in the devices connected to my wireless network. I highly recommend this device to improve the security of your home network. I would like the app would block internet access to all new devices discovered by default. Hopefully the future update to include this new feature.
