Chemical-Terrorism Vulnerability Information (CVI) Authorized User Training

Chemical-terrorism Vulnerability Information (CVI) is used to protect information developed under the Chemical Facility Anti-Terrorism Standards (CFATS) regulation (6 CFR Part 27) that relates to vulnerabilities of high-risk chemical facilities that manufacture, use, store, or otherwise possess certain explosive, reactive, flammable, or toxic chemicals of interest (COI).

Only CVI Authorized Users with a need to know can have access to CVI.

Complete and submit the CVI training and the CVI Authorized User Application: Safeguarding Information Designated as Chemical-terrorism Vulnerability Information (CVI).

Note: This training does not make any determination on your need to know the CVI. The holder of the CVI or an appropriate Cybersecurity and Infrastructure Security Agency (CISA) official will make this decision each time a request for access to or disclosure of CVI is made.

CISA will review the information you provide upon completion of this training and, if you are approved as a CVI Authorized User, CISA will notify you with an email providing a unique CVI Authorized User number and certificate to confirm your status.

Contact Information

If you have any difficulty with submitting the CVI Authorized User Application, please call the Chemical Security Assessment Tool (CSAT) Help Desk at 866-323-2957 Monday through Friday (except federal holidays) from 8:30 a.m. to 5 p.m. (ET) or email
