Am I playing with fire on my umbrella policy?

[Logan I.]

I am holding my properties in my own name, no LLC etc. For protection, I have a massive landlord and umbrella insurance (1m, 2m respectively). For simplicity, I have a website with "business name" which lists all the properties, and also have a credit card in that name. The "business name" is not registered officially or incorporated in any way. Am I playing with fire in regards to the properties being part of a business and compromising my umbrella insurance coverage?

Your thoughts are much appreciated.
