Frequently Asked Questions

What is the IASC?

The Internet Abuse Signal Collective, or the IASC is a data-sharing collaborative network led by WhoisXML API that brings together organizations to exchange internet telemetry and threat intelligence.

Its goal is to combine data from multiple sources to get a clearer, more complete view of internet activity and use that to detect, investigate, and mitigate cyber threats more effectively than any single organization could on its own.

How does the IASC work?

The IASC operates by collecting and correlating data contributed by its partners. Each participant shares unique data and, in return, gains access to a broader pool of intelligence. The scope of access depends on the level and value of contribution, creating a collaborative data exchange that benefits all members.

What are the requirements to become a partner?

Organizations across commercial, government, and non-commercial sectors can apply to become an IASC partner as long as it has relevant data, expertise, or capabilities to contribute. The IASC is built on mutual collaboration — partners share what they can and gain access to a wider range of intelligence in return. IASC also welcomes individual contributors.

What kind of data can partners contribute?

Partners can contribute a wide range of internet and threat-related data. It includes:

• domain and IP intelligence
• DNS and network traffic
• malware and phishing infrastructure
• spam signals
• Indicators of compromise
• honeypot data
• geolocation insights

And more. Essentially, it could be any data that helps build a clearer picture of the global online activity and threats.

Can partners use IASC data for their own internal security?

Yes. The goal of the IASC is to enable data sharing so that each individual partner can do more with the help of IASC data than without it. Partners are encouraged to use IASC data to strengthen their own security, conduct research, and enhance cybersecurity products or operations. All data must be used responsibly and for legitimate purposes aligned with combating cyber threats under established IASC guidelines.

What benefits do partners get from joining the IASC?

Partners gain access to a diverse and enriched pool of data that goes beyond what any single organization can collect on its own. The level of access is flexible and generally scales with contribution. To align data sharing and access with your organization’s goals, IASC representatives work directly with partners to define the best collaboration model.

Can research institutions participate?

Yes. The IASC welcomes research groups and independent researchers. If you are interested in contributing or using IASC data for research, you can reach out to explore collaboration opportunities.
