I don't believe you. Some companies may not have the capabilities to defend against state-sponsored attacks today, but that's only because their executives have chosen to be willfully ignorant and not devote sufficient resources to the problem. There's a whole industry of consultants and outsourcing services which provide exactly this capability. All you have to do is write a check.

Show me who I need to write a check to defend against a 0-day exploit that was used against Cisco networking equipment. Which in turn was used to compromise security mechanisms within the company.

Oh wait you can't. Which is why we had to turn to our government intelligence services to provide assistance.

So stop pretending like companies can defend against state sponsors who are buying 0-days for $100k+ like it's candy.

The NSA certified the Boeing SNS Server and BAE Systems XTS-400 as stuff they couldn't hack at that point. They're used as guards to protect secrets on classified site from attacks on Internet side. There's been no published hacks of those systems for almost 30 years. You could try to see if you can buy them. I linked to descriptions of some of those products here:

I described what I learned about how high-assurance security builds stuff here:

As I often said, compare anything from security market advertised as secure against stuff on that list. If they're missing something, they're probably insecure. Now, I'm still not saying you can stop nation states and all 0-days. I am saying that most of the $100k 0-days are preventable with architectures like above with apps in safe languages with guards separating trusted things from untrusted things. Ada has also been around a long time with Rust getting popular now.

What makes most companies not use stuff like that isn't that level of security being unachievable: they just don't want to for management's reasons which range from arbitrary to sound practices in a profit-focused environment.

"I don't believe you." You can't just change the organization, culture, and procedures of a company just by throwing money at consultants.

That's like saying a big family can solve their feuds and mental illnesses just by writing a check to team of group therapists and lawyers.

Defense from foreign attacks is one of the main reasons for the federal government to even exist. You can blame the victims all you want but diplomatic and military defense is still the government's responsibility.

Even small nation states have a hard time defending against the larger ones, it is as you correctly identify merely a matter of writing a larger check but the amount on that check is so much larger than what is feasible that even the largest nation states find themselves routinely hacked.

Security is hard. So hard that no matter what amount of money you spend you will still be vulnerable, but maybe a bit less so. There are no absolutes in this.
