Electronic Submission Guidelines for Critical Infrastructure Information (CII)

The following guidelines will help you successfully complete an electronic submission.

  • The electronic submission process MUST be completed in a single session as information cannot be saved and completed at a later date.
  • All necessary information should be available prior to beginning the electronic submission process as the portal will shut down, and all information will be deleted, after 60 minutes of inactivity.  Submitters will be prompted before they are disconnected to give them an opportunity to continue with their submission.
  • The time required to submit CII will depend on the number, size, and format of the uploaded files as well as the connection speed.
  • There is no limit to the number of files that can be submitted but files must be submitted in groups no greater than 10 files and not exceed 100 MB in total size.
  • Submitters must use Microsoft Internet Explorer version 5.5 or higher, Netscape 7.1 or higher or Firefox 1.0 as their browser.
  • All file types and formats are accepted by the PCII Program Office.
  • As a further security measure, submitters are encouraged to provide a digital signature.  Although not required, a digital signature authenticates the submitter’s identity guaranteeing the original content of documents has not been altered in transmission.  A Certificate Authority issues digital signatures and can be located through most online search engines.
  • Selecting the “Cancel” button, before uploading files, will end the submission process and all information related to the submission will be deleted.
  • The submission process cannot be cancelled after CII files have been uploaded to the PCII Program Office.
