Scrum is a process with way more than just daily stand ups. Obviously a company can do whatever works for them, but formal 'scrum' involves time-delineated sprints, planning meetings, demos, retrospectives, the daily stand ups, pointing stories and a handful of other aspects.

NB: I'm not trying to advocate for it - it works for some teams, but everyone is different.
