About
Us

We’re built differently. We deliver real-time IP, domain and threat intelligence that is uniquely diverse. We are independent and uncompromised by commercial bias. We work proactively to make the internet safer for all.

Data that makes an impact

Born of a mission-driven partnership that's trusted by billions of users globally, including law enforcement, analysts, defenders, and solution providers alike. The Spamhaus-abuse.ch Alliance delivers objective, real-time IP, domain, and threat intelligence that is uniquely diverse.

We are built on a commitment to making the internet safer, operating with a clear purpose: empowering security professionals with the highest quality data to protect, enrich, and increase resilience against threats.

By analysing 7 billion data points on average every 24 hours, we provide actionable datasets that protect 4.5 billion users globally. This data disrupts the activities of some of the world's most notorious offenders. It truly makes a difference.

Extended visibility

Billions of data points, analyzed each day, come from a huge range of sources, including global contributor communities, law enforcement agencies, internet service providers, big data netflow providers, email service providers, S&P 500 businesses and beyond.

Broad coverage

Every 24 hours the Spamhaus-abuse.ch Alliance tracks over 3 million URLs used for malware distribution, has a database of over 1 million IOCs, maintains intelligence on millions of phishing and spam Internet resources, and confirms thousands of active botnet C2s.

Reliable datasets

We maintain 16 core datasets, each with a dedicated focus, covering malware, phishing, spam, historical context, insights, and classifications. With our low false-positive rates, users have control and flexibility to address unique needs with confidence.

We’re always hunting

All of our datasets are available in real-time, with information that is made available for use within seconds of being detected by our hunters and automated systems. See our Threat Map here for the IP address locations of servers being actively used to control computers infected with malware.

Our Team

100% Independent. Driven by Impact.

Both Spamhaus and abuse.ch have been around since the early days of the Internet, when the Internet was a new "Wild West.” This attracted a team that grew organically with a deep passion that still unites us all today—to effect change, move the dial, and make the Internet a safer place.

To create the most reliable data, we believe community is critical. Be that with individual contributors or commercial enterprises, Community provides the Power of Many - indicators shared by a global force for earlier detection, identification and confirmation of patterns, clusters, and anomalies, reducing time-to-response.

  • Our specialisms

    Spamhaus was born with a focus on malicious email, and abuse.ch with a focus on malware. Our Alliance now means users get data from across the attack chain: from phishing, to tracked intelligence on malware URLs, IOCs, and files to botnet communication end points. We support you to protect and uncover more with confidence.

  • Our coverage

    We have been working against Internet abuse for almost 30 years. We have built and maintained trusted industry relationships with registries, networks and the wider Internet community, where data affects change. These relationships are two directional, allowing us to offer uniquely diverse insight, while providing meaningful data for the good of the internet.

  • Our methodology

    A highly skilled set of Detection Engineers utilize Open Source Intelligence alongside machine learning and heuristics to analyze our huge volumes of data to detect malicious behaviour at speed. Meanwhile, our Threat Hunting team analyze, track, and detonate malware, to produce data that is trusted and reliable.
