A digital assistant is a software application designed to perform tasks, answer questions, or provide information using voice or text commands. Commonly powered by artificial intelligence (AI) and natural language processing, digital assistants can manage schedules, send messages, search the web, and control smart devices. Examples include Siri, Alexa, and Google Assistant. In cybersecurity, digital assistants can both enhance productivity and introduce risks, such as unauthorized data access or exposure of sensitive information, making secure configuration and usage essential.
