Malicious Domain Blocking and Reporting (MDBR)

This no-cost service is available for U.S. State, Local, Tribal and Territorial government (SLTT) members of the MS-ISAC and EI-ISAC in partnership with Cybersecurity and Infrastructure Security Agency (CISA) and Akamai. This service provides an additional layer of cybersecurity protection that is proven, effective, and easy to deploy.

MDBR technology prevents IT systems from connecting to harmful web domains, helping limit infections related to known malware, ransomware, phishing, and other cyber threats. This capability can block the majority of ransomware infections just by preventing the initial outreach to a ransomware delivery domain.

Please provide your organization email address

If your organization is not currently a member, you will need to join the MS or EI ISAC prior to signing up for the MDBR service.


*We will check your organization email address against our list of current MS-ISAC and EI-ISAC members to confirm that your organization is already a member.
