You can define "enterprise tools" any way you like, but there are software tools that cost millions of dollars that only an "enterprise" would ever buy, and tools like the JetBrains tools that are priced at a level where many individuals buy them for themselves. Many tools like this are still very popular within enterprises, as are many free, open-source tools, so you might mean "commonly used within enterprises" when you say "enterprise tools" but it's more common (I believe) for people to mean expensive tools that ONLY an enterprise would ever buy when they say "enterprise tools".
