Palo Alto Networks DNS Security - subscription license (3 years) - 1 device in HA pair

DNS is wide open for attackers. Attacks using DNS often succeed because security teams lack basic visibility into how threats use DNS to maintain control of infected devices or steal data. Current approaches drown you in uncoordinated data from independent tools or require changes to DNS infrastructure. DNS Security service applies predictive analytics, machine learning, and automation to block attacks that use DNS. Tight integration with the firewall gives you automated protections and eliminates the need for independent tools.
