Spamhaus Block List

What it contains

IP addresses appearing to be under the control of, or made available for the use of, senders of Unsolicited Bulk Email (UBE). Includes: IPs identified to Spamhaus’ best ability as likely direct spam sources, spammer hosting/DNS, spam gangs and spam support services.

Benefits to you

Filters out a significant majority of email threats before they have a chance to access your network, giving you and your security team more time to focus on in-depth analysis and investigation.


Exploits Block List

What it contains

IP addresses that host bots and malware-infected computers. Automated tools observe SMTP connections for an extremely large set of both spamtrap and production mail servers in near-real-time to find connections that show characteristic patterns of malware or botnet-infected computers.

Benefits to you

Cyber criminals exploit and hijack legitimate networks so with XBL you can block email traffic from what might first appear to be a trusted source.


Policy Block List

What it contains

IP address ranges for end-user devices, such as home routers and smart TVs, from which email should never be sent. The PBL lists IPs not because they are actively sending spam, but as a pre-emptive measure to prevent spam from networks that should send no email at all.

Benefits to you

There’s been a massive growth in IoT devices but not all are secured correctly. The PBL blocks potential unwanted email traffic while still keeping you connected to devices for their intended purpose.

Power up

In addition to the ZEN list of IP addresses, Spamhaus has developed Power Up data sets to boost protection against specific threat types.

Power Up data sets include AuthBL developed to combat spoofing of SMTP Authentication used by spammers and cyber criminals to get privileged access they don’t deserve.

The Spamhaus AuthBL lists:

AuthBL provides an effective way of rejecting botnet traffic before it can enter your network, with very little risk of blocking legitimate users attempting to login. It is of particular value to companies which are prone to attacks intended to compromise customer accounts.
