State Border Guard Service of Ukraine

The State Border Guard Service of Ukraine, also known as Ukraine border control or DPSU, is a governmental law‑enforcement agency tasked with protecting the nation’s state border. Its core functions include preventing illegal crossings, combating smuggling and trafficking, enforcing customs regulations, and managing migration flows at land, sea, and air checkpoints. The agency operates under the Ministry of Internal Affairs and carries out both preventive and investigative activities to safeguard territorial integrity. In addition to traditional security duties, it coordinates with other state bodies during emergencies and contributes to national defence efforts. The service maintains a permanent presence at numerous border crossing points, including the Siret crossing into Romania where a cyber incident was observed.

The agency’s distinguishing attributes lie in its specialised focus on border security and its regulatory authority over customs and migration matters. It possesses specialised units trained to detect and respond to threats ranging from illicit goods to cyber‑targeted attacks, as demonstrated by the wiper malware incident on 26 February 2022 that disrupted computer systems at a border station. This event highlighted the agency’s reliance on digital infrastructure for processing refugees and its vulnerability to cyber warfare during conflict. Structurally, the State Border Guard Service of Ukraine is a state entity with no private ownership; it is directly subordinate to the Ministry of Internal Affairs and does not have a parent or subsidiary organisation. Its nationwide network of detachments and checkpoints enables it to execute its mandate across Ukraine’s extensive border perimeter.
