How do tech companies prevent against corporate espionage? For ex what stops a Tesla competitor from sending a plant to work and spy on their battery technology?

Well, tech companies have a few ways to prevent corporate espionage. For starters, they might have strict security protocols in place for their facilities, so it’s hard for a Tesla competitor to get in. They might also do background checks on employees to make sure that their motivations are legit and that they don’t have any ties to competitors. Lastly, they could also have surveillance systems in place to monitor their facilities and make sure that no one is snooping around where they shouldn’t be.
