Introducing the Critical Infrastructure Sectors: Postal Services

21. mája 2026

The Critical Infrastructure Association of the Slovak Republic continues its series of articles introducing both the public and the professional community to the individual sectors of critical infrastructure as defined by Act No. 367/2025 Coll. on Critical Infrastructure and on Amendments to Certain Acts. Following sectors such as energy, transport and finance, we now turn to a sector that is part of the daily life of citizens as well as the functioning of the state – postal services.

Why postal services are critical infrastructure


Postal services ensure the physical movement of consignments, documents and goods between citizens, businesses and public authorities. Even in the digital era, postal communication remains irreplaceable for the delivery of official decisions, court documents, electoral materials, pensions, medicines and e-commerce consignments. An outage or long-term disruption of this service has direct impacts on the exercise of public authority, the social security of the population, the functioning of the business environment and, in crisis situations, also on the supply of the population.


It is precisely this combination – nationwide availability, connection to the exercise of state administration and interlinkage with goods logistics – that is the reason why the legislator classified postal services among the sectors of critical infrastructure.


Central state administration body


The central body of state administration for the postal services sector is the Ministry of Transport of the Slovak Republic. The Ministry is responsible for the formulation of policy in the area of postal services, designates the critical infrastructure entities within the sector, assesses risk analyses and security plans of operators, and coordinates the sector with other state components in the management of emergencies. Regulatory competences in the area of the postal market are exercised by the Regulatory Authority for Electronic Communications and Postal Services.


Which entities are part of the postal services sector


Within the postal services sector, the Act does not define sub-sectors. The entities are providers of the universal postal service pursuant to § 3 par. 1 of Act No. 324/2011 Coll. on Postal Services and on Amendments to Certain Acts:


§ 3 Universal Service
(1) The universal service is an offer of postal services under paragraph 2, which serves to ensure the minimum satisfaction of the needs of all users of postal services within the territory of the Slovak Republic, so as to ensure the availability of access points of the public postal network and contact points of the public postal network, under equal conditions, in the prescribed quality, at a reasonable price, every working day with at least one collection and delivery per day. The provider of the universal service is one or more postal undertakings, which is obliged to provide the universal service on the basis of a postal licence and under the conditions and in the manner set out in this Act.


The provider of the universal postal service is the entity to which this obligation has been imposed on the basis of a postal licence issued by the Regulatory Authority for Electronic Communications and Postal Services. In the territory of the Slovak Republic, the provider is Slovenská pošta, which by law ensures the nationwide delivery of letter consignments, registered and official consignments, parcels up to a specified weight, as well as postal payment services, including the payment of pensions and social benefits.

An entity providing the universal postal service becomes a critical infrastructure entity in the postal services sector upon meeting the criteria set by the Act on Critical Infrastructure and its implementing regulations, with the decision on inclusion being made by the central body of state administration.


Within the postal services sector, the following areas are distinguished in particular:



·       Universal postal service – nationwide delivery of letter consignments, registered consignments, official consignments and parcels up to a specified weight, including the delivery of pensions and money orders.

·       Postal payment services – payment of social benefits, pensions and other monetary entitlements through the postal network.

·       Delivery of official consignments – delivery of documents from public authorities with legal effects (legal fiction of delivery).

·       Express and courier services and parcel delivery – commercial delivery of consignments, including the e-commerce segment.

·       Sorting and logistics centres – hub facilities ensuring the processing and routing of consignments.


Specifics of the sector


Postal services have several characteristics that distinguish them from other sectors:


·       Nationwide coverage and accessibility – the network of post offices and delivery districts covers the entire territory of the state, including sparsely populated areas.

·       Personnel intensity – operations rely on a large number of delivery personnel and branch employees, which makes the sector sensitive to labour-related disruptions.

·       Hybrid nature – a combination of physical logistics and digital systems (sorting lines, IT for consignment tracking, electronic services).

·       Connection to public authority – delivery with legal effects, payment of benefits, distribution of electoral materials.

·       Cross-border dimension – interconnection with international postal operations and customs procedures.


Risks of the sector


The sector faces a combination of physical, personnel, technological and cyber risks:

·       failure of sorting centres (fire, technical malfunction, sabotage),

·       cyberattacks on information systems, ransomware on the control systems of sorting lines,

·       disruption of electricity and fuel supplies,

·       shortage of delivery personnel, strikes, pandemic restrictions,

·       misuse of the postal network for the transport of dangerous substances or prohibited goods,

·       dependence on external IT and logistics service providers,

·       growing pressure of e-commerce on network capacity and the related operational risks.


In crisis scenarios (energy crisis, armed conflict, large-scale cyber incident), the ability of the post to continue delivering official consignments and paying out benefits is one of the indicators of the state's resilience towards the population.

In January 2024, an employee of a financial firm in Hong Kong executed a transfer worth 25 million US dollars. He did so after a video conference with the chief financial officer and colleagues from headquarters that appeared entirely authentic. Yet on the call he was the only real person. The other participants were deepfake replicas generated by generative artificial intelligence on the basis of publicly available recordings. This case, documented by the Hong Kong police, did not announce the arrival of a new threat. It announced that the threat is already here and is operating in production mode.

V januári 2024 zamestnanec finančnej spoločnosti v Hongkongu uskutočnil prevod v hodnote 25 miliónov amerických dolárov. Urobil tak po videokonferencii s finančným riaditeľom a kolegami z centrály, ktorá pôsobila úplne autenticky. Na konferencii však bol jediný skutočný človek on sám. Ostatní účastníci boli deepfake repliky vygenerované generatívnou umelou inteligenciou na základe verejne dostupných záznamov. Tento prípad, zdokumentovaný hongkonskou políciou, neoznámil príchod novej hrozby. Oznámil, že hrozba je už tu a funguje v produkčnom režime.

The Slovak Republic is in the final phase of a process that is fundamentally changing the approach to the protection of critical infrastructure. In accordance with Act No. 367/2024 Coll. on Critical Infrastructure, the list of entities that will be officially identified as critical for the functioning of the state is to be completed in July 2026. This step represents one of the most important milestones in the implementation of the new regulatory framework, the aim of which is to increase the resilience of key systems to crises, cyber threats and service outages. A new framework of responsibility Inclusion among the critical entities will not be of a merely formal nature. For the organisations concerned, it will mean the introduction of precisely defined obligations in the area of risk management, security measures, incident management and the very continuity of the provision of essential services within the meaning of the Act. For many entities, this represents a fundamental change in the approach to security, which will require systematic preparation even before the actual inclusion in the list. Growing interest of companies in the regulation Already in this period it is evident that potentially affected entities are beginning to intensively follow the development of the legislation and of the implementing rules being prepared. The reason is the need to set up internal processes in good time, so that the transition to the new regime can take place without major operational complications. The growing demanding nature of the requirements is at the same time increasing the demand for expert guidance and methodological support. The role of the Critical Infrastructure Association of the Slovak Republic In this context, the Critical Infrastructure Association of the Slovak Republic (AKI SR) plays a significant role, as it has long been creating a professional platform for cooperation between the state sector, regulators and operators of essential services across all sectors of critical infrastructure, such as for example energy, transport, healthcare or digital infrastructure. As Tibor Straka, President of AKI SR, states: “The process of identifying critical entities is not merely a legislative obligation. It is the moment that determines how resilient the state will be in real crisis situations.” The Association points out in this connection that the period before the final inclusion in the list is the most important one for organisations from the point of view of preparation and adaptation. Room for timely preparation Companies that may be part of the list of critical entities currently have a unique opportunity to prepare for the new obligations systematically and well in advance. In this area, AKI SR provides expert support, methodological guidance and a platform for the sharing of experience between the individual sectors. Cooperation as the foundation of resilience The implementation of the new system for the protection of critical infrastructure will be successful only if it is built on close cooperation between the public and the private sector. In this respect, AKI SR is developing a systematic dialogue with the central bodies of state administration that exercise state administration in the individual segments of critical infrastructure. With many of them, the Association has concluded memoranda of cooperation, which makes possible a more effective interconnection of expert capacities, the exchange of information and coordination in addressing key security topics. In the process, AKI SR thus acts as a natural communication and expert bridge between the regulator and the entities of critical infrastructure, while helping to connect legislative requirements with their practical implementation in the individual sectors. A new stage in the protection of critical systems The finalisation of the list of critical entities in July 2026 represents a fundamental step in the modernisation of the system for strengthening the resilience of critical infrastructure in Slovakia. The new legislative framework sets clearer rules, but at the same time significantly raises the demands placed on the preparedness of the organisations concerned. The outcome of the entire process will depend on how well it is possible to align the regulation with the reality of the operation of critical entities.

Slovenská republika sa nachádza v záverečnej fáze procesu, ktorý zásadne mení prístup k ochrane kritickej infraštruktúry. V súlade so zákonom č. 367/2024 Z. z. o kritickej infraštruktúre má byť v júli 2026 dokončený zoznam subjektov, ktoré budú oficiálne identifikované ako kritické pre fungovanie štátu. Tento krok predstavuje jeden z najdôležitejších míľnikov implementácie nového regulačného rámca, ktorý má za cieľ zvýšiť odolnosť kľúčových systémov voči krízam, kybernetickým hrozbám a výpadkom služieb. Nový rámec zodpovednosti Zaradenie medzi kritické subjekty nebude mať len formálny charakter. Pre dotknuté organizácie bude znamenať zavedenie presne definovaných povinností v oblasti riadenia rizík, bezpečnostných opatrení, incident manažmentu a samotnej kontinuity poskytovania základných služieb v zmysle zákona. Pre mnohé subjekty ide o zásadnú zmenu prístupu k bezpečnosti, ktorá si bude vyžadovať systematickú prípravu ešte pred samotným zaradením do zoznamu. Zvyšujúci sa záujem firiem o reguláciu Už v tomto období je zrejmé, že potenciálne dotknuté subjekty začínajú intenzívne sledovať vývoj legislatívy a pripravovaných vykonávacích pravidiel. Dôvodom je potreba včas nastaviť interné procesy tak, aby prechod do nového režimu prebehol bez zásadných prevádzkových komplikácií. Rastúca náročnosť požiadaviek zároveň zvyšuje dopyt po odbornom vedení a metodickej podpore. Úloha Asociácie kritickej infraštruktúry SR V tomto kontexte zohráva významnú rolu Asociácia kritickej infraštruktúry Slovenskej republiky (AKI SR) , ktorá dlhodobo vytvára odbornú platformu pre spoluprácu medzi štátnym sektorom, regulátormi a prevádzkovateľmi základných služieb naprieč všetkými sektormi kritickej infraštruktúry, ako je napríklad energetika, doprava, zdravotníctvo či digitálna infraštruktúra. Ako uvádza prezident AKI SR Tibor Straka: „Proces identifikácie kritických subjektov nie je len legislatívna povinnosť. Je to moment, ktorý určuje, ako odolný bude štát v reálnych krízových situáciách.“ Asociácia v tejto súvislosti upozorňuje, že obdobie pred finálnym zaradením do zoznamu je pre organizácie najdôležitejšie z hľadiska prípravy a adaptácie. Priestor na včasnú prípravu Firmy, ktoré môžu byť súčasťou zoznamu kritických subjektov, majú v súčasnosti jedinečnú príležitosť pripraviť sa na nové povinnosti systematicky a s dostatočným predstihom. AKI SR v tejto oblasti poskytuje odbornú podporu, metodické usmernenia a platformu na zdieľanie skúseností medzi jednotlivými sektormi. Spolupráca ako základ odolnosti Implementácia nového systému ochrany kritickej infraštruktúry bude úspešná len vtedy, ak bude postavená na úzkej spolupráci medzi verejným a súkromným sektorom. V tomto smere AKI SR rozvíja systematický dialóg s ústrednými orgánmi štátnej správy, ktoré vykonávajú štátnu správu na jednotlivých úsekoch kritickej infraštruktúry. S mnohými z nich má asociácia uzatvorené memorandá o spolupráci, čo umožňuje efektívnejšie prepájanie odborných kapacít, výmenu informácií a koordináciu pri riešení kľúčových bezpečnostných tém. AKI SR tak v procese vystupuje ako prirodzený komunikačný a odborný most medzi regulátorom a subjektami kritickej infraštruktúry, pričom pomáha prepájať legislatívne požiadavky s ich praktickou implementáciou v jednotlivých sektoroch. Nová etapa ochrany kritických systémov  Finalizácia zoznamu kritických subjektov v júli 2026 predstavuje zásadný krok v modernizácii systému zvyšovania odolnosti kritickej infraštruktúry na Slovensku. Nový legislatívny rámec nastavuje jasnejšie pravidlá, ale zároveň výrazne zvyšuje nároky na pripravenosť dotknutých organizácií. Výsledok celého procesu bude závisieť od toho, ako dobre sa podarí zosúladiť reguláciu s realitou prevádzky kritických subjektov.

In August 2023, something happened on the Polish railways that until then had belonged to the realm of scenarios, not reality. Unknown actors abused the radio system for emergency stopping (radio-stop) and transmitted a signal that brought more than 20 trains to a halt in various regions of the country. The attack required no access to digital systems and no sophisticated malware. A radio transmitter and knowledge of publicly available tones were enough. It was a demonstration of why rail transport ranks among the most complex categories of critical infrastructure. It brings together older analogue and radio technology with contemporary IT and OT systems, and each of these layers has its own vulnerabilities.

V auguste 2023 sa na poľskej železnici udialo niečo, čo dovtedy patrilo do oblasti scenárov, nie reality. Neznámi aktéri zneužili rádiový systém núdzového zastavenia (radio-stop) a vyslali signál, ktorý zastavil viac ako 20 vlakov v rôznych regiónoch krajiny. Útok nepotreboval prístup do digitálnych systémov ani sofistikovaný malvér. Stačil rádiový vysielač a znalosť verejne dostupných tónov. Bola to ukážka, prečo železničná doprava patrí medzi najkomplexnejšie kategórie kritickej infraštruktúry. Spája sa v nej staršia analógová a rádiová technika so súčasnými IT a OT systémami a každá z týchto vrstiev má vlastné zraniteľnosti.

Roughly 99 % of the world's intercontinental digital communication does not travel through satellites. It travels through a network of approximately 600 submarine fibre-optic cables with a combined length of 1.4 million kilometres, lying on the floor of the world's oceans. Through these cables flow more than 10 trillion US dollars in financial transactions every day, the bulk of email and cloud traffic, and almost all international internet traffic. They are the physical rope on which the digital economy hangs.
