Futureproofing Spamhaus
Spamhaus Statements
Spamhaus Sponsors
As demand for Spamhaus data has increased over the years, Spamhaus has met requirements by forming strategic partnerships with companies able to fulfil tasks which the Spamhaus Project, as a not-for-profit threat intelligence research organization, has no commercial interest in handling itself. These strategic partnerships have allowed the Spamhaus Project to meet the high demand for its data while freeing its resources to focus solely on what the Spamhaus Project does best; spam research and development of anti-spam technologies.

Our Strategic Partners include:

Spamhaus Technology LTD. is a British data delivery company specialising in managing data distribution and synchronization services for large scale spam filter systems.

Spamhaus Technology provides commercial distribution services for the technologies developed by the Spamhaus Project, such as the Spamhaus threat intelligence Datafeed. These are resource-intensive services for which there is high demand but which the Spamhaus Project, as a not-for-profit threat intelligence research organization, has no commercial interest in handling itself.

Spamhaus Systems

Spamhaus Systems S.L.U. specialises in providing licensed access to realtime cyber-security data produced by the Spamhaus Project.

Typically the services provided by Spamhaus Systems cover non-email based use of the data, such as Response Policy Zones (DNS firewalls) and delivery of broader threat intelligence via APIs. Where geographically appropriate, Spamhaus Systems S.L.U. also supplies security data for large spam filtering systems.



Strategic partner firms are wholly independent separate legal entities. No strategic partner has any authority to obligate or bind The Spamhaus Project or any other strategic partner vis-à-vis third parties, nor does The Spamhaus Project have any such authority to obligate or bind any strategic partner firm. The Spamhaus Project does not provide commercial services, does not enter into commercial contracts, and does not receive or derive any income from any strategic partners or their commercial activities.
