what does enterprise mean?

hello /prog/

Could anyone tell me what people are trying to say when they say something is enterprise? I don't get why this word is thrown around so much on job ads and development platforms and such. Is there a difference between something that is enterprise and something that is not enterprise?

I think I understand now, thanks.

but what about:

| we secure enterprise information and applications on today's most popular mobile devices
| we secure enterprise information
| enterprise information

I am confused.
