A stable solution that can be used for upgrades, vulnerability remediation, configuration, and standardization
I am using the latest version of Cisco OpenDNS. Users should prioritize the challenges that they have before implementing the solution. They need to be very clear about what they are looking for. Those parameters need to be defined, success criteria need to be checked, and then they can proceed with the solution that meets the requirements. Overall, I rate Cisco OpenDNS a nine out of ten.
