We offer a zero dollar subscription model, meaning that after you've bought your CUJO unit there are no monthly or annual fees. That said, your CUJO works by constantly communicating to our security network, which requires expensive upkeep and internet security is only effective if it's constantly being updated. Our team of security experts will use the latest security practices to keep your home safe against newest types of network attacks. Enterprises pay thousands for such a service, we make it available for homes for much less.
