I assume you don't -san about the company or organization that employs you, on
the grounds it'd be akin to using it about your own family members.

But when is it usually used? Is it merely when you're talking about the
organization itself (eg "This event was supported by Microsoft") rather than
when you're merely talking about something associated with the organization
(eg "This product runs on Microsoft Windows")?

question
usage politeness honorifics
When do you use -san about a company?
It can be used for companies because companies have a "quasi-personality", but
not for their products. But if you use it for companies, it will sound like
you are a business person.

answer
-san is polite but not honorific. I would use it in polite conversation, in cases where you have some connection with the company you're referring to (maybe they're a customer, or they did some work for your company, or whatever).
