An employer requests security clearance on an employee

Supo only performs security clearance vettings when there are statutory grounds for doing so.

The applicant for security clearance vetting is most commonly a prospective employer who is engaging a new employee. The organisation requesting the vetting (usually an employer) thereby becomes a client of the Supo vetting department, whereas the subject of the vetting is the individual on whom the report is compiled.

The Security Clearance Act precisely specifies the conditions under which employers are eligible to request Supo security clearance vetting on an employee. These conditions relate to the duties and protected interests referred to in the Act, such as national security, preparations for a state of emergency, and public safety.

Security clearance vettings are conducted on the staff of central government ministries, and of administrative units falling within the purview of the Ministry of the Interior

Established clients of the Supo vetting department include government ministries, the Parliament of Finland, the Office of the President of the Republic, and agencies subordinate to the Ministry of the Interior, such as the police. These clients generally always request security clearance vetting when recruiting new staff members.

Security clearance vetting(s) may also be conducted when individuals wish to train for certain occupations, such as by seeking to enrol at the Police College of Finland.

Security clearance is discretionary for other government or business sector employees

Supo also performs security clearance vettings on other individuals in government service when their duties are important for national security. 

Security clearance vetting may be performed on staff members in private businesses operating in such sectors as energy generating, transport or telecommunications, or in major export businesses. Subcontractors supplying outsourced IT and other services to these enterprises may also be subject to security clearance.
