15-Second summary
Assessing an indicator means manually pulling context from multiple tools that don’t talk to each other, a process that is slow, error-prone, and creates friction at exactly the moment when speed matters most.
Feedly Threat Intelligence now surfaces GreyNoise enrichment directly inside IOC Insight Cards, bringing open-source and closed-source intelligence together in a single pane of glass, so you can make faster, more confident decisions without ever leaving the platform.

Assessing an IOC
When a CTI analyst is working through an IOC collection workflow, the core question is always the same: is this indicator worth acting on?
Answering it confidently means pulling together multiple signals. OSINT gives you a strong foundation: threat actor associations, malware families, and recent mentions across your source collection. But IOCs have a short lifespan, and forming a complete picture before that window closes requires merging open-source intelligence with enriched data from platforms like GreyNoise. That process is manual by nature, spread across multiple tabs, and easy to get wrong. Until now, it has meant running parallel workflows in order to make a confident call.
Connect Feedly Threat Intelligence and GreyNoise
IOC Insight Cards now bring Feedly Threat Intelligence’s OSINT and GreyNoise data together in one place. If you have a GreyNoise license, you can enrich any indicator with GreyNoise’s classification signals directly alongside Feedly’s validated OSINT layer, which aggregates over 10,000 CTI sources and cross-references indicators against MISP warning lists using NLP models fine-tuned on manually annotated datasets to ensure every indicator is genuinely malicious before it surfaces. This is where open-source and closed-source intelligence meet.
The result is a richer, more complete picture of every indicator. OSINT context tells you who is behind a threat. GreyNoise’s behavioral signals tell you what that threat is actively doing and helps you move from raw context to confident actions faster, with all of the intelligence in one place.
A 360-degree view of every indicator
IOC Insight Cards already offer a comprehensive OSINT view of every indicator and it’s related cyberattacks, threat actors, malware families, and more. With GreyNoise data now layered in, you get behavioral and classification signals in the same place as your OSINT context, you get the full picture in one place.
For analysts who triage high volumes of IP indicators, that complete view is the difference between a confident call and an inconclusive one.
Set it up in minutes
Connecting GreyNoise to Feedly Threat Intelligence doesn’t require professional services engagement or a backend configuration. You simply bring your existing GreyNoise license, connect it in your account settings, and enrichment surfaces automatically across your IOC Insight Cards from that point on.
Your data stays yours
Security teams handle sensitive intelligence, and how that data is managed matters. The GreyNoise data you bring into Feedly is visible only to you. It is not stored by Feedly, not shared across accounts, and not accessible to other users in your organization. Your vendor subscription powers your own enriched view and no one else’s.
