A good way to tell whether a "cybersecurity expert" truly knows something about cybersecurity is to take a look at their website, assuming they have one.
Does the site look like something coded for a middle school project?
If so, you might want to be skeptical.
If, for example, the newly appointed informal cybersecurity advisor to President-elect Donald Trump has a company website that looks like it was built after a handful of coding classes, it makes sense to doubt his expertise.
Folks on the internet immediately denounced the cybersecurity chops of former New York City Mayor Rudy Giuliani, who was announced as an informal cyber advisor to Trump on Thursday.
Giuliani runs a management firm called Giuliani Partners that houses a company branch allegedly dealing with security services.
