Cisa
CISA (Costruzioni Italiane Serrature e Affini) is an iconic Italian lock and access-control brand, founded in 1926 by Luigi Bucci. It built its reputation early by patenting the first electrically controlled lock the same year it was founded—basically kicking the door open (politely, with a latch) on modern electromechanical access control.
Today CISA positions itself as “CISA Italy,” with design and engineering made in Italy, and a product ecosystem that spans both mechanical and electronic security for residential, public, and commercial buildings.
Ownership / group: CISA is a strategic brand of Allegion and has been part of the Allegion group since 2013 (around the time Allegion became a standalone listed company).
What they’re known for (in the real world, on real doors):
-
Mechanical locks and cylinders, including solutions for master keying systems (CISA talks a lot about cylinders/keys and master-key systems production).
-
Electric / electromechanical locks (heritage category for them), including locks designed to pair with panic hardware or remote electric opening in access-control setups.
-
Exit / panic devices (their ranges are explicitly positioned around installability and reliability, and they’re tracking new EU regulatory changes in their comms).
