The certificate in cybersecurity I was referring to is a CISSP. It takes a few weeks to master the ideas and get a certificate, and then your dad would be qualified for cybersecurity consulting jobs. As I mentioned, cybersecurity consulting is mostly about re-organizing governance, and making PowerPoints about that re-organization. And there are a lot of openings, and more every day, due to the scariness of the threat of Russian cyberattacks.
