Protection from APTs and malware communicating with C&Cs and botnets

Infoblox leveraged our market-leading DNS technologies into the industry’s first true DNS-based network security solution. Infoblox DNS Firewall protects against advanced persistent threats (APTs) and malware by disrupting the ability of infected devices to communicate with command-and-control (C&C) sites and botnets, so that information is not exfiltrated.

DNS Firewall is a purpose-built software application based on Response Policy Zone (RPZ) for use on Infoblox DNS servers. It interprets DNS responses, leverages threat intelligence on known malicious destinations, and instantly takes action based on RPZ policy, effectively preventing devices from becoming infected due to APTs and malware.


Through the power of Infoblox Grid™, DNS Firewall continually shares information with an Infoblox Reporting Server on DNS attempts to communicate with malicious destinations. Reports on infected devices (user, IP address, MAC address and other data), top threats, top bad domain connection attempts, and more can help your IT security team quickly take action.


DNS Firewall helps make sure that threat intelligence stays current with the evolving threat landscape through an automated threat intelligence service. Data is refreshed every two hours (or more often for a significant threat) to reflect newly discovered malicious domains and IP addresses.
