As of June 6, 2025, at 0900 EDT, the Department of Defense (DoD) has officially shut down what was known as the “DIBNet Portal,” marking a significant transition in how cyber incidents are reported across the Defense Industrial Base (DIB). This change is part of a broader modernization and cost-reduction initiative within the DoD, aimed at streamlining cybersecurity practices and aligning with evolving federal budget priorities.
If your organization is a DoD contractor, this change directly affects your compliance obligations under DFARS 252.204-7012. Here's what you need to know and how to stay compliant.
Since June 6, the original DIBNet portal URL (https://dibnet.dod.mil) now redirects to a new page hosted by the Defense Cyber Crime Center’s DCISE (Defense Collaborative Information Sharing Environment).
The decommissioning of the DIBNet portal appears to be part of a long-term modernization effort, but there has not been wide reporting on this update. This move can also be viewed as a step towards a more secure and streamlined reporting infrastructure for defense contractors.
