Frequently Asked Questions
Cisco recognizes that privacy is important to you, so we design and operate our services with the 
protection of your privacy in mind. If you enroll in SenderBase Network Participation, Cisco will collect 
aggregated statistics about your organization’s email traffic; however, we do not collect or use any 
personally identifiably information. Any information Cisco collects that would identify your users or 
your organization will be treated as confidential.
Why should I participate?
Participating in the SenderBase Network helps us help you. Sharing data with us is important to helping 
stop email-based threats such as spam, viruses and directory harvest attacks from impacting your 
organization. Examples of when your participation is especially important include:
Email attacks that are specifically targeted at your organization, in which case the data you 
contribute provides the primary source of information to protect you. 
Your organization is one of the first to be hit by a new global email attack, in which case the data 
you share with us will dramatically improve the speed with which we are able to react to a new 
threat. 
What data do I share?
The data is summarized information on message attributes and information on how different types of 
messages were handled by Cisco appliances. We do not collect the full body of the message. Again, 
information provided to Cisco that would identify your users or your organization will be treated as 
confidential. (See 
 below).
