You're talking about Squads basically. Bring different people in the same group. And yeah, QA is very similar to Security in some points, but if you think straight QA should include security. Weird to say that a software has quality without security included, but the truth is that security is specific that the regular QA usually can't handle.

You've capitalized Squad, but it's hard to Google. Where did you get that term, and where is it defined outside your head?

As xxr said, Squad is how Spotify names their (previously Scrum) teams. Other interesting concepts they use are "Tribes" and "Guilds". Take a look at the Spotify engineering practices, they are really inspiring.

Not the commenter you're replying to, but at least at my organization we borrow the term from Spotify.
