The most impressive feature of BlueCat Edge is its versatility combined with robust security. It acts as a central platform that intelligently routes traffic to the correct resolver while simultaneously enforcing security policies. This includes the ability to blacklist malicious domains or redirect traffic, providing a significant security advantage. In my experience, I've successfully migrated nearly 100,000 internal IP addresses across 14 global data centers using BlueCat Edge, handling a substantial amount of traffic with ease. The interface is user-friendly, and what I find most helpful is the ability to quickly view logs. These logs contain all the queries from internal clients and the corresponding responses from the DNS service, making troubleshooting DNS traffic significantly easier. In the past 24 hours, we've seen 86,000 unique IP addresses using the service, though this number likely fluctuates seasonally. Overall, it's the best solution I've found for troubleshooting DNS traffic. The unparalleled visibility offered by BlueCat Edge is arguably the most critical benefit we receive.
