Spam senders

Spamhaus Block List


What it contains

IPs identified to Spamhaus’ best ability as likely:

  • Direct spam sources,
  • Spammer hosting/DNS
  • Spam gangs
  • Spam support services.
Benefits to you

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

Bot & malware infected computers

Exploits Block List


What it contains

IP addresses hosting:

  • Bots
  • Malware-infected computers.

Automated tools observe SMTP connections for spamtrap and production mail servers in near-real-time to find 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.

IoT devices

Policy Block List


What it contains

IP address ranges for end-user devices from which email should never be sent:

  • IoT devices
  • Home routers
  • Smart TVs

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. Keep connected to IoT devices for their intended purpose while blocking unwanted email traffic.
