NIETP Common Security Warnings & Site Access Errors

The CAE in Cyber Defense Program is currently undergoing a review and update of the application process. Input is being solicited from all CAE-CD designated institutions to inform this evolution. After input from all designated institutions is compiled, a detailed process will be presented. As a result of this evolution, 2020 CAE-CD re-designating schools will automatically be given a no-lapse extension of at least one-year. Re-designating CAE-Rs will still need to submit an application for re-designation.

New applicants and schools in the Candidates Program will follow directions from the CAE Candidates Program National Center as to how and when to apply. New applicants should complete the Applicant Checklist as per usual. Any new schools wishing to apply as a CAE-R should contact the NCAE-C Program Management Office at
