Asec
ASEC is a trade-focused security hardware brand built around the “everyday kit” locksmiths and installers reach for, with a big emphasis on breadth, availability, and value rather than boutique-only spec pieces. The brand was established in 2003 and was created specifically to support independent retailers and security professionals with products that “would never become available through the large multiple retailers.”
Where ASEC gets especially interesting (and why it tends to become a “default stock brand”) is the scale of the range:
-
ASEC positions itself as having a portfolio of 2,000+ individual products, described as one of the largest ranges under a single security brand name in the industry.
-
Coverage is intentionally broad across the core trade categories: Access Control, Architectural Hardware, Key Cutting, Locking Products, UPVC, Tools & Accessories.
ASEC is exclusive to Aldridge Security (whom we distribute) in the UK trade ecosystem (Aldridge explicitly calls itself the exclusive distributor of ASEC Security Products worldwide). That exclusivity is a big part of the brand’s identity: it keeps the range aimed at the trade channel rather than getting diluted into mass retail.
