Veterans who verify through the id.me platform can qualify for free cybersecurity training that goes from beginner level (A+,Network+, etc.) all the way to a CISSP certification.
The training program is built by the CERT group out of the Carnegie Mellon University.
The program is hosted by the DHS, so this is literally your tax dollars at work. Enjoy!
