I work in a heavily regulated industry (healthcare) and I can tell you that if anti-virus products weren't required to pass audits we wouldn't be using them. I'm not super familiar with Windows built-in security anymore but macOS (our platform of choice) is pretty secure without any additional products. In fact, I'm pretty sure that adding A/V "solutions" makes us more vulnerable, not less.
