best-kept secrets
Closely guarded knowledge
Best-kept secrets are things few people know about—hidden gems, insider knowledge, or information deliberately concealed.
The phrase often describes underrated places or tips: This restaurant is one of the city's best-kept secrets.
It can also refer to information someone has successfully hidden: Her past was a best-kept secret until the biography appeared.
