Getting Started with Infoblox Threat Defense

Infoblox Threat Defense integrates threat intelligence feeds, rules, custom lists, category and application filters, and advanced analytics to strengthen your network’s security and protect you from escalating cyber threats that can adversely affect your business. Infoblox Threat Defense combines secure DNS resolution in the cloud with advanced analytics tools for detecting and preventing a broad range of threats, such as DGA families, data exfiltration, lookalike domains, and fast flux. These tools consist of reports, active indicators, Threat Lab, Dossier research, and TIDE (Threat Intelligence Data Exchange) and are based on machine learning, highly accurate and aggregated threat intelligence, and automation. All these features work together to provide insight into your network’s security and into infected and compromised devices.

To begin protecting your network with Infoblox Threat Defense, use the Infoblox Portal to define a network scope to which you will apply security configuration. The network scope can include your company's public networks, roaming end users, and on-premise networks (including the NIOS Grid). Next, configure custom lists, add filters, and apply security policies to the network scope. Based on your subscription level, Infoblox Threat Defense will automatically apply threat intelligence feeds to your defined networks.
