Police Security Service

The Police Security Service (PST) is Norway’s domestic intelligence and security agency, tasked with safeguarding the nation against threats such as terrorism, espionage and extremist violence. It operates under the authority of the Ministry of Justice and Public Security and provides security assessments and advice to government institutions, including the parliament, ministries and critical infrastructure. PST conducts threat analysis, runs security vetting for personnel with access to classified information and monitors activities that could undermine democratic processes. The service also offers protective security for high‑profile individuals and venues, coordinating with the police and other emergency responders when needed. In its daily work PST collects and evaluates information from both open sources and confidential channels to produce actionable intelligence for decision‑makers. The 2017 spear‑phishing incident, in which PST’s email systems were targeted by a Russian‑linked group, illustrates the agency’s role in detecting and responding to cyber threats against Norwegian state entities.

PST’s distinguishing attribute is its focus on internal security rather than foreign intelligence, placing it at the intersection of law enforcement and national security policy. It maintains close cooperation with foreign intelligence and security services, NATO partners and EU bodies to exchange information on transnational threats while preserving Norway’s sovereignty over its domestic security apparatus. The agency’s regulatory role includes advising on legislation related to security clearance, data protection and the handling of classified material, thereby influencing the framework within which other public agencies operate. Structurally, PST is a government agency that reports to the Ministry of Justice and Public Security and has no parent corporation or subsidiary structure. Its competencies are built around analytical expertise, technical surveillance capabilities and a tradition of operating within strict legal and democratic oversight mechanisms. This combination of a clear domestic mandate, international liaison and accountability to elected officials defines PST’s position within Norway’s security landscape.
