THREAT-WATCHPUBLIC SECTOR
Cybersecurity for Public Sector
Public administration bodies are named under NIS2 and face both opportunistic attacks and higher public accountability when something goes wrong.
Why this sector is different
NIS2 names public administration entities (central government and, at member states' discretion, certain regional/local levels) among its regulated sectors. Public bodies also tend to run a wide mix of legacy and modern systems, often with limited internal security staffing relative to the size of the attack surface they're responsible for.
How NIS2 applies to public administration
Public administration entities are listed in NIS2 Annex I, and the size thresholds that let smaller private companies out of scope apply differently here: member states may bring public bodies in regardless of headcount, and Greece's Law 5160/2024 sets the national position. The practical consequence is that a small municipality or agency can carry obligations a private company of the same size would not. Article 20 also bites harder in this context: the management body must formally approve cybersecurity risk-management measures and can be held personally accountable, which in a public body means named officials rather than an abstract board. Registration with the National Cybersecurity Authority is the practical starting point, and the registration platform has been operational since July 2025.
What coverage looks like in the public sector
Two constraints shape everything. Procurement is the first: security is bought through public tender, on multi-year cycles, with award criteria fixed long before the threat landscape moves, so the specification you write matters more than the vendor you pick. Legacy is the second: public bodies typically run systems well past supported life because replacement requires budget cycles nobody controls, which makes compensating controls the working strategy rather than modernization. Add to that the fact that citizen data attracts both criminal and state-aligned interest, and that ENISA's 2025 landscape records public administration as one of the most targeted sectors in the EU, and the realistic goal becomes defensible evidence of continuous monitoring rather than a clean architecture diagram.
Ransomware against essential services
Municipal and government systems are attractive ransomware targets because service disruption is highly visible and politically costly.
Legacy system exposure
Long system lifecycles common in public administration mean unpatched or end-of-life software is a persistent risk.
Limited internal security capacity
Many public bodies don't have the budget or headcount for an internal 24/7 SOC, making outsourced monitoring a practical necessity rather than a luxury.
Procurement cycles that outlast the threat
A tender specified two years ago is defending against a two-year-old threat model. Specifications that buy an outcome and a review cadence, rather than a fixed tool list, age considerably better.
