What Sewosy does

Sewosy is a privately held French family company founded in 2000 and headquartered in Haguenau, Alsace, that designs, develops, and manufactures electrical, electromagnetic, and electromechanical locking solutions and access control systems. Its portfolio spans approximately 2,000 product references across 11 product categories and 11 registered trademarks, including electromagnetic locks (VELMAG®), adjustable-counterplate handle strips (CPREG®), adjustable-roller electric strikes (ROUREG®), electromagnetic locks for sliding doors (KLAK®), the connected centralized access control system KEOLA®, standalone RFID/keypad access control (PASS®), power supplies (WATT'SAD®), stainless-steel push buttons (SYNE® INOX), and complementary accessories. Core technology relies on low-voltage DC (12V/24V) electromagnetic attraction between coils and counterplates, with patented installation-friendly features (CPREG adjustable counterplate, ROUREG adjustable roller) and certifications including NF S 61-937 (French emergency exit standard), EN 1155, and IP42–IP68 ingress ratings for indoor and outdoor use.

The company's commercial model is hardware-only B2B sales with no subscription or recurring component disclosed; products are sold as one-time purchases to professional installers (electricians, low-current specialists, locksmiths) and distributors via a direct commercial team and downloadable catalogue, with no public pricing and no consumer e-commerce storefront. End-customer use cases span six horizontal segments—tertiary/office buildings, public buildings (ERP), industry and logistics, retail, residential, and furniture/equipment—giving Sewosy a diversified demand base within the French domestic market. Operational recognition includes EcoVadis sustainability rating, Marque Alsace, La Fabrique by Alsace, and Bpifrance Le Club Excellence, and the company maintains an English-language version of its website signaling nascent internationalization intent. The firm employs approximately 30 collaborators and is led by CEO Carine Rossdeutsch-Wolff and operational director Julien Schoettel.

Direct peers

• BKS: German specialist in locking technology, panic hardware, and access control systems under the GU Group. Comparable as a European specialist in door hardware and electromagnetic locking, often specified in commercial and public-building projects.
• Salto Systems: Spanish-based specialist in electronic access control with cloud and mobile credential platforms (SALTO KS, Space). Closest comparable to Sewosy's KEOLA® connected access control offering, focused on electronic locks and software-driven access management.
• Cisa: Italian locks and access control brand owned by ASSA ABLOY, producing electric strikes, electromagnetic locks, and access control devices. Direct product overlap with Sewosy in electromagnetic locks and electric strikes for the European market.
• GEZE: German manufacturer of door, window, and safety technology including electromagnetic hold-open devices and integrated access control. Direct comparable in fire-rated door hardware and electromagnetic hold-opens, with similar focus on European commercial/public-building specifications.
• Vachette: French brand (ASSA ABLOY) specializing in locks, cylinders, and access control, including electromagnetic solutions. Comparable as a French-market competitor to Sewosy, with stronger parent-company backing and broader channel reach.

Broad incumbents

• dormakaba: Swiss-listed global provider of access, entrance, and security solutions, including electromagnetic locks, door hardware, and enterprise access control. Overlaps directly with Sewosy's electromagnetic lock and access control portfolio but serves a much broader international customer base.
• ASSA ABLOY: Global leader in access solutions and locking hardware, including electromagnetic locks and connected access products (e.g., Aperio). Comparable as a direct competitor in the electromagnetic lock and access control space, but operating at vastly greater scale and geographic reach than Sewosy.
• Allegion: US-listed global security products company with brands like Von Duprin, Schlage, and LCN, offering electrified door hardware and access control. Comparable in product category (electrified locks, strikes, access control) but a much larger multinational incumbent.
• ABUS: German family-owned manufacturer of security products including mechanical and electronic locks, padlocks, and access control. Comparable in family-owned heritage and lock-focused product portfolio, with a broader consumer and commercial presence.

Regional players

• Bricard: French heritage brand for high-security locks, cylinders, and door hardware, now part of the Lockforce group. Comparable as a French specialist in locking hardware with similar specification channels, though with a more security-cylinder focus.
