ISEO
ISEO (often written ISEO Serrature) is an Italian access-solutions manufacturer best known for cylinders, locks, padlocks, panic/escape hardware, and mechatronic + digital access control. The group is headquartered in Pisogne (Brescia), Northern Italy, on the shores of Lake Iseo—which is where the name comes from.
The company was founded in 1969 by Giuseppe Facchinetti, originally producing locks, cylinders and padlocks before expanding into broader access control. Today, ISEO presents itself as a global access-control player with 1,000+ employees, a presence in 100+ countries, 13 branches, and 4 manufacturing plants (listed as Italy, France, Germany, and Romania).
Where ISEO gets especially relevant for modern installs is the bridge between mechanical security and connected access. Their “Connected Smart / ARGO” ecosystem is marketed for residential and light-commercial sites, using an app-centric approach to manage access and operate compatible devices like electronic cylinders (e.g., Libra).
