The European Travel Information and Authorization System (ETIAS) is set to revolutionize border security in the European Union. Scheduled for operation in 2025, it will screen travelers from visa-exempt countries, enhancing security by identifying potential threats such as terrorism, organized crime, and illegal migration. Regulated by EU legislation and involving a detailed application process, the system collects and cross-references traveler data with various databases to assess security, public health, and migration risks. While ETIAS is a powerful tool for counterterrorism, preventing entry of potential terrorists, it is also an advanced counterintelligence asset, employing intelligence capabilities to detect espionage and Intelligence related activities and act as a deterrent to potential spies. With a comprehensive approach, the present paper describes the ETIAS promises to bolster EU security.
