LenelS2 Enterprise Access Control in Chicago

Enterprise Access Control Heritage

LenelS2 is the result of merging two access control companies: Lenel Systems International and S2 Security. Lenel, founded in 1995 in Rochester, New York, became the dominant enterprise access control platform in North America, with its OnGuard software managing door access at corporate headquarters, hospitals, universities, and government buildings. S2 Security, based in Framingham, Massachusetts, developed cloud and hybrid access control solutions.

Both companies were acquired by United Technologies Corporation (UTC) and later became part of Carrier Global Corporation (NYSE: CARR) when UTC separated its building technology divisions. The LenelS2 brand now operates under Carrier’s security portfolio alongside Kidde (fire), Edwards (fire), and other building safety brands.
