Featured Reviews

Richard Polyak - PeerSpot reviewer
A robust solution designed to inspect network and form an internal topology network with clients
While we haven't explored AI-driven features yet, it's part of our roadmap for future versions. I would recommend F5 BIG-IP DNS to others in the industry. Overall, I would rate it an eight out of 10 as it meets our current needs but it will always have room for improvement.
Partha Dash - PeerSpot reviewer
Protects against threats by quickly identifying insider risks and compromised devices
Palo Alto should explore agentless approaches to integrate DNS Security more easily and efficiently. The existing system sometimes presents challenges with backbone routing, impacting productivity. An agentless approach could be more lightweight and user-friendly. Additionally, there is a need for improvement in the pricing model for support and license renewals.
