A cyber threat intelligence feed is a real-time data stream that gathers and analyzes cyber risk information. It provides security teams with the information they need to proactively identify and mitigate threats and attacks. It also enables them to take a more proactive approach to security and shift from reactive to predictive.

The types of data cyber threat intelligence feed in a threat intelligence feed vary, from technical to tactical and strategic, and include indicators of compromise (IOCs) as well as attack patterns and techniques. Security teams can access threat intelligence from a variety of sources, including open-source and commercial feeds.

Tactical threat intelligence focuses on the tactics, techniques and procedures (TTPs) of malicious actors. It helps speed up incident response times and reduces the impact of successful attacks by providing security teams with IOCs they can use to detect and prevent them. Tactical threat intelligence can be gathered through a number of methods, including security feeds, social media and observable activity on network devices.

What an IP Address Abuse Feed Is and Why It Matters

A tactical threat intelligence feed will also typically contain details on known vulnerabilities in software and hardware, along with attack methods and the tools used to exploit them. This information can help cybersecurity teams prioritize patching efforts and implement additional security controls to mitigate the risk of exploitation.

An effective threat intelligence feed will be curated and provide actionable, relevant data for each specific security context. This helps to save time for security teams and integrate with existing tools to reduce the need for bolt-on technologies. To ensure the value of a threat intelligence feed, look for sources that are reputable and align with your organizational security landscape. The following trusted OSINT feeds offer curated, relevant and regularly updated information that can improve visibility, accelerate threat detection, and minimize attack surface exposure.
