Mailing Lists and Feeds

Subscribe to a Mailing List

CISA offers two cybersecurity mailing lists that you can subscribe to:

  • Cybersecurity Advisories: up to the minute, relevant cybersecurity threat information, along with best practices for cybersecurity network defenders to action. Data and information reflect consolidated cyber data, insights, and analysis from CISA’s public-private sector partners and international partners.
  • Vulnerability Bulletins: weekly summaries of new vulnerabilities that do not pose immediate risk to systems but are significant enough that non-compliance with suggested actions and mitigation guidance may pose risk to your network. Includes multiple daily notification of patch releases. 

To learn more or subscribe, visit the subscription system. and complete the process. You will need to confirm your subscription by responding to an email message that will be sent to the address you provide. If you have any questions, read the FAQ.
