Chemical Security Assessment Tool (CSAT)

The Chemical Security Assessment Tool (CSAT) is an online portal that houses the surveys and applications facilities must submit to the Cybersecurity and Infrastructure Security Agency (CISA) to determine which facilities are considered high-risk under the Chemical Facility Anti-Terrorism Standards (CFATS). These surveys and applications include the Top-Screen survey, Security Vulnerability Assessment (SVA), Site Security Plan (SSP), and Personnel Surety Program (PSP).

In September 2016, CSAT 2.0 was released in conjunction with the CFATS enhanced tiering methodology to improve integration between surveys and to more appropriately identify and tier high-risk chemical facilities. CSAT 2.0 consists of the revised and streamlined Top-Screen survey, SVA, and SSP. Visit CSAT SSP Revisions to learn more about these updates.

Register to Access CSAT 2.0

CSAT is a secure web-based system that can only be accessed by Chemical-terrorism Vulnerability Information (CVI) certified individuals. After completing CVI training, facilities should register for a user identification and password on the CSAT website. The Agency will validate a facility's registration and notify the facility on how to access CSAT.

Facilities can then log into CSAT to complete the Top-Screen survey. The information a facility submits is used by the Agency to determine if they are considered a high-risk chemical facility covered by CFATS.

If a facility is considered high-risk, the SVA and SSP surveys will unlock in their CSAT account.
