Security firm here, we do weekly meetings solely because our tempo is different. An individual researcher, analyst or pentester might have his own engagement to take care of that is relatively independent.

For us, weekly meetings are more of a phoning home than a game plan meeting. I can see situations in which stand up meeting might be useful, -> when there is mutual overlap between engagements.

In answering your question though, the need for stand up meetings, imo, is dictated by the size of the group working on the same project.
