sécurisé

Sécurisé is a French adjective formed from the verb sécuriser, meaning made secure or protected. It describes something that has been fortified against danger, unauthorized access, or loss, and is widely used in technology, logistics, and everyday language. Common expressions include système sécurisé, données sécurisées, et communication sécurisée, as well as accès sécurisé and lieu sécurisé. The term emphasizes compliance with security requirements, such as encryption, authentication, or tamper-resistant processes.

Étymology: sécurisé derives from sécuriser, which in turn traces to Latin securus meaning free from care. In French the past participle agrees with the noun it modifies: un système sécurisé, une connexion sécurisée, des lieux sécurisés.

Usage notes: In IT and cybersecurity, secure data and communications are described as sécurisées; in commerce and administration one speaks of paiements sécurisés, sites sécurisés, et comptes sécurisés. The word is typically contrasted with terms like vulnérable, non sécurisé, or peu sûr. Related terms include sécurité (security), sécurisation (the act of making secure), and sécurisant (that which secures).
