Who is involved?

The customers are businesses and public administrations who need access in the exercise of their activities to classified information or sensitive professions, buildings or events. They often work in vital sectors such as security, defense, aerospace and the nuclear industry. At international level, the National Security Authority is working closely with national security authorities in other countries and major international organizations such as the European Union (EU) and the North Atlantic Treaty Organization (NATO).

legal persons and independent consultants

All applications by individuals must invariably be linked to a legal person authorized to handle classified information. Therefore, independent consultants cannot apply for a personal security clearance without first applying for a security clearance for legal entities for their business, even if it is a one-man business.



When a company wants to compete in a bid relating to classified contracts or access other classified information, it is compulsory to launch an application  for a security clearance for legal entities, mentioned above, before the National Security Authority (NSA).

Individuals must always submit their application for a personal security clearance through a legal entity. The clearance at the level of the legal entity must be finalized before employees can apply for a security clearance for natural persons.


The public sector (national and international)

Employees of administrations and international organizations that have access to classified information must be holders of a security clearance. In addition, authorities may ask the NSA to perform a security check for access to sensitive functions, buildings or events, on the people involved. Depending on the legal basis for the security screening (according to the Law of 11.12.1998), the NSA can provide a security attestation or a security advice after the security screening.
