VINCE is the Vulnerability Information and Coordination Environment developed and used by the CERT Coordination Center to improve coordinated vulnerability disclosure.
VINCE documentation is available here: https://vuls.cert.org/confluence/display/VIN/.
You can report a bug, feature request, or other issue in this GitHub project. VINCE users can also send feedback through the Private Message feature.
Currently, VINCE is only a single-instance platform operated by the CERT/CC for our coordinated vulnerability disclosure service. We intend to publish VINCE source code here, when ready.
