A malicious IP feed is a critical piece of the modern cybersecurity posture, providing organizations with a dynamic list of identifiers of compromise (IoCs) associated with malware distribution, phishing, command and control servers, and other malicious activities. These IoCs are critical for quick incident response, enabling security teams to identify and block connections to these harmful IP addresses before an attack can take place.

A malicious IP threat intelligence feed enables you to improve your next-generation firewall’s ability to detect and protect against advanced cyberattacks. The feeds provide real-time threat data on a range of malicious activity, including reconnaissance, malware distribution and execution, and DDoS attacks. In addition, they can help you spot patterns in suspicious network traffic that may be indicative of an ongoing attack.

How a Malicious IP Feed Helps You Detect Threats in Real-Time

Malicious IP feed rules can be used in firewall policies, proxy policies, local-in policies, and ZTNA rules to prevent or log connections to specific IP addresses that have been flagged as high-risk by trusted threat advisories. These rules are important for reducing false positives so that security teams can focus on other threats.

GreyNoise customers also rely on the feed to identify malicious scan and attack observables that appear in their environment but don’t represent a significant enough of an attack worth an analyst’s time to investigate further. Combined with our unique visibility into actual real-time attacks and our extensive enrichment capabilities, the feed provides an invaluable tool to navigate the threat landscape.

The feed is compiled from multiple exclusive Radware threat intelligence sources and correlated by our ERT Active Attackers research team. The feed is designed to complement our existing threat detection and prevention capabilities, including our global deception network and our proprietary bot and DDoS intelligence algorithms.…
