The Spamhaus Project

Protecting users since 1998

For over two decades, Spamhaus has been making a difference. From launching threat intelligence through IP and domain blocklists to working with law enforcement cybercrime units. Industry groups around the world have recognized Spamhaus' contribution to making the Internet safer.
After working with Spamhaus for nearly two decades on various research and investigations, I admire their commitment to identifying digital crime and abuse, as well as providing threat intelligence for law enforcement, first responders, and cybersecurity practitioners.
