And also worth noting that "place a hostile intelligence service may be interested in" can be extremely broad. I think people have this skewed impression they're only after assets that work for goverment departments and defense contractors, but really, everything is fair game. Communications infrastructure, social media networks, cutting edge R&D, financial services - these are all useful inputs for intelligence services.

These are also softer targets: someone working for a defense contractor or for the government will have had training to identify foreign blackmail attempts and will be far more likely to notify their country's counterintelligence services (having the penalties for espionage clearly explained on the regular helps). Someone who works for a small SaaS vendor, though? Far less likely to understand the consequences.
