The head of the National Security Agency, Jacek Siewiera, informed on TVP Info about Poland sending a Polish advisory mission to Finland. The team would include specialists who helped plan the border barrier and would cover the full operation to safeguard Poland’s border as well as share valuable expertise with allies.
Poland Will Assist Finland
Following Finnish President Sauli Niinistö’s visit to Poland, and during talks with President Andrzej Duda, Finland formally requested an advisory mission from Poland. The invitation was received yesterday, noting the intensification of a hybrid threat along the Finnish border, which is proving particularly challenging to defend. The head of the National Security Bureau described the decision as a response to that request and to the evolving security landscape.
Today, the National Security Agency confirmed the plan to deploy specialists who participated in preparing the barrier and who managed Poland’s border protection operation beginning in 2021. This mission aims to transfer practical lessons learned during that period and to provide on-site support for Finland in facing similar challenges.
The purpose of the mission centers on sharing a broad set of experiences gained at that time. Poland faced a wide spectrum of threats, including information operations, cognitive warfare, and issues related to international law. It also encompassed operational responses to incidents such as border violations by helicopters and other intrusions on Polish airspace. These experiences are seen as directly transferable to allied security efforts today.
All of these lessons are viewed as potential knowledge that can benefit NATO allies. The Polish side emphasizes that, just as Britain dispatched technical troops and advisers during Poland’s border preparations in 2021, Poland is ready to offer its expertise to its new partners within NATO structures. The discussion also highlighted work in the cognitive domain, the involvement of civilian movements and non-governmental organizations, and how the public arena can influence state responses to forced migration.
Siewiera also noted the mission’s broader context on the X platform, describing an official Finnish request for allied support in the face of a hybrid attack. Poland intends to answer positively, sending a team of military advisers to share border-security knowledge at an operational level for on-site guidance.
A Necessity for Border Closure
The head of the National Security Agency described the decision to close additional border crossings between Finland and the Russian Federation as a necessity. He pointed to Finland’s record rise in attempts to cross the border illegally by individuals with visas issued in Russia and contrasted this with a noticeable drop in similar incidents on the Polish border. He added that maintaining the eastern border barrier is a key priority in ongoing political dialogue about national security and border control.
In his view, the current course aligns with what the future government and parliamentary majority have advocated regarding the barrier. The President welcomed the continued commitment to the barrier as a prudent security measure.
Finland’s Border with Russia
On Tuesday, Finland’s government decided to shut the entire border with Russia. Emigrants entering Finland from Russia will not be allowed to cross the eastern border to seek asylum. Goods will still be transported across the border, but asylum claims will not be processed there. The move followed concerns about inflows from third countries and was framed by the Finnish Prime Minister as a response to organized activity by the Russian state aimed at asserting influence.
During autumn, nearly 1,000 people from third countries reached Finland via the eastern border without proper documents. Some traveled along the border by bicycle or scooter. The main border crossings in Karelia, which see heavy traffic from St. Petersburg and Moscow, were closed for three months starting mid-November, with other northern checkpoints closing in the days that followed through December.
Further context about Finland’s response was published by wPolityce and others, noting official statements about the border measures and the broader strategic picture. The ongoing dialogue reflects a united approach among Western allies in handling hybrid threats and border-security challenges. This coverage is cited here as part of the record of public statements on the matter.
