The adjective prudent means something or someone that is being careful and avoiding risk.

Synonyms are cautious, discreet, economical or frugal.

The word origins from Old French (13th century) prudent meaning “with knowledge, deliberate”, and from Latin prudentem meaning “knowing, skilled, sagacious, circumspect”, rarely in literal sense “foreseeing”, contraction of providens, present participle of providere meaning “look ahead, prepare, supply, act with foresight”. It comes from pro meaning “ahead” plus videre meaning “to see”.
