Cybersecurity Ireland – Threats, Strategy and a Growing Industry

Cybersecurity Ireland is a sector of growing strategic and economic importance, shaped by the country’s unique position as a major European data processing hub. Ireland hosts an estimated 30% of all EU data, is the lead GDPR regulator for many of the world’s largest technology companies, and has experienced high-profile attacks including the devastating 2021 HSE ransomware incident. The all-island cybersecurity sector now encompasses more than 630 firms, employs around 8,000 professionals and generates an estimated €3.2 billion in annual revenue. This guide covers the threat landscape facing Ireland, the role of the National Cyber Security Centre (NCSC), the emerging NIS2 regulatory framework, and the industry’s ambitious growth targets for 2030.

🔓 Ireland’s Cyber Threat Landscape

Ireland’s exposure to cyber threats is amplified by its role as a hub for global technology, financial services and pharmaceutical operations. The country processes a disproportionate share of European personal data through the headquarters and data centres of companies including Google, Meta, Apple, Microsoft and TikTok. This concentration of sensitive data makes Ireland a high-value target for cybercriminals, state-sponsored actors and hacktivists.

The most significant cyber incident in Irish history was the Conti ransomware attack on the Health Service Executive (HSE) in May 2021, attributed to the Russia-linked cybercrime group Wizard Spider. The attack crippled hospital IT systems across the country, encrypted approximately 80% of the HSE’s IT environment, forced the cancellation of thousands of appointments and outpatient services, and compromised the personal data of almost 91,000 patients and staff. The HSE estimates the total cost of the attack at €102 million, with the Comptroller and Auditor General estimating that an additional €657 million in cybersecurity upgrades is needed over seven years. More than 470 legal proceedings have been issued against the HSE in relation to the breach, and in December 2025 the HSE began offering €750 compensation to affected individuals. The attack exposed critical gaps in Ireland’s cyber resilience and prompted renewed urgency around national cybersecurity investment.

The NCSC’s 2025 National Cyber Risk Assessment identifies three primary risk categories facing Ireland: the dynamic geopolitical environment, which has increased state-sponsored cyber activity targeting critical infrastructure; evolving technology and its security implications, particularly the use of artificial intelligence to enhance attack capabilities; and supply chain security, where vulnerabilities in third-party software and services can cascade across multiple organisations. The CyberPulse Ireland 2025 survey found that 51% of Irish office workers feel more vulnerable to cyberattacks than a year ago, while 57% admitted to unintentionally contributing to a security incident at work.

🛡️ The National Cyber Security Centre

The NCSC is Ireland’s lead authority for cybersecurity, operating under the Department of the Environment, Climate and Communications. It serves as the national Computer Security Incident Response Team (CSIRT) and is responsible for monitoring threats, issuing advisories, coordinating incident response and developing national cybersecurity strategy.

The NCSC has faced persistent criticism regarding its resourcing and staffing levels relative to the scale of threats facing Ireland. At the time of the HSE attack, the NCSC had only 25 staff members, an annual budget of €5 million, no dedicated premises, and its Director position had been vacant for a year owing to an uncompetitive salary of €89,000. While funding and staffing have increased in subsequent years, critics argue that the centre remains under-resourced compared to equivalent bodies in other EU member states, particularly given Ireland’s outsized role in hosting European technology operations and processing an estimated 30% of all EU data.

Ireland’s National Cyber Security Strategy provides the overarching policy framework for the country’s approach to cybersecurity. The NCSC has also established a Cyber-CORE (Co-ordination and Response) programme to facilitate cybersecurity information sharing across sectors, and published a national cyber emergency plan. These initiatives are intended to ensure that supporting structures are in place ahead of the more demanding requirements being introduced through the NIS2 Directive.

📜 NIS2 Directive and the National Cybersecurity Bill

The NIS2 Directive represents the most significant overhaul of EU cybersecurity legislation to date, replacing the 2016 NIS Directive with substantially expanded scope and stricter requirements. Ireland missed the transposition deadline of October 2024 and is currently subject to infringement proceedings by the European Commission. The forthcoming National Cybersecurity Bill is the proposed legislation to transpose NIS2 into Irish law, with the NCSC expecting passage by the end of 2025 or early 2026.

Under NIS2, thousands of Irish organisations classified as essential or important entities – spanning sectors including energy, transport, healthcare, financial services, digital infrastructure and public administration – will be required to implement comprehensive cybersecurity risk management measures and report significant incidents to competent authorities. Management boards will bear direct responsibility for overseeing cybersecurity compliance, with maximum administrative fines of up to €10 million or 2% of worldwide group turnover for essential entities that fail to comply.

Ireland is adopting a distinctive regulatory model for NIS2 implementation. Rather than centralising all enforcement under the NCSC, the approach will see the NCSC serve as Lead Competent Authority and Single Point of Contact, while sector-specific regulators will oversee enforcement within their respective domains. This mirrors the distributed model Ireland has adopted for AI regulation under the EU AI Act, where 15 National Competent Authorities share oversight responsibilities.

In June 2025, the NCSC published draft Risk Management Measures (RMMs) guidance and launched Ireland’s participation in the CyberFundamentals (CyFun) framework, originally developed in Belgium. CyFun provides a tiered, standards-based approach grounded in the NIST Cybersecurity Framework, offering organisations a structured pathway to demonstrate NIS2 compliance. The NCSC has recommended CyFun as the preferred compliance method, while noting that alternative frameworks such as ISO 27001, ISO 62443, COBIT and NIST standards are also acceptable. A national certification system under CyFun is expected to take 18 to 24 months to establish.

💼 Ireland’s Cybersecurity Industry

Ireland’s cybersecurity industry has grown substantially over the past decade, driven by the country’s position as a technology hub and the increasing global demand for security products and services. The 2025 All-Island Cybersecurity Sector Report, commissioned by Cyber Ireland and NI Cyber through InterTradeIreland’s Synergy Programme, identified 632 unique cybersecurity firms across Ireland and Northern Ireland. The all-island sector generated an estimated €3.2 billion in revenue and €1.5 billion in Gross Value Added in the most recent financial year, with Irish firms recording a compound annual growth rate of 13.4% over the previous two years.

Six of the world’s top ten cybersecurity software companies have operations in Ireland, including Check Point, CrowdStrike and Fortinet. The sector spans dedicated cybersecurity product and service companies, diversified firms offering cybersecurity as part of a broader technology portfolio, and large organisations maintaining significant internal cybersecurity teams. Cork has a strong cluster of international cybersecurity operations including McAfee and Sophos, while Galway hosts Hewlett Packard Enterprise’s European cybersecurity operations hub. Dublin remains the primary location for cybersecurity company headquarters and talent concentration.

The sector employs approximately 8,000 professionals, up from around 2,000 in 2019 – representing significant growth but still well short of demand. Cyber Ireland, the national cybersecurity cluster organisation headquartered at Munster Technological University, estimates that an additional 1,000 people per year need to be trained, upskilled or recruited to meet projected demand. Job roles grew from 2,000 to 6,700 between 2019 and 2022, and a quarter of Irish companies report difficulty recruiting staff with cybersecurity skills according to the European Commission’s 2024 Eurostat survey.

🎓 Skills, Education and the Talent Pipeline

The cybersecurity skills gap is one of the most pressing challenges facing both the industry and the organisations it protects. According to Ibec’s digital and AI policy division, the European Commission has set a target for ICT specialists to reach 10% of the workforce by 2030 under its Digital Decade roadmap, up from just over 6% in Ireland in 2024. Meeting this target will require sustained investment in education, conversion courses and professional upskilling.

Several Irish universities now offer specialised master’s degrees and diplomas in cybersecurity, with Munster Technological University playing a particularly prominent role given its partnership with Cyber Ireland. Technology Ireland Skillnet offers dedicated upskilling programmes, while apprenticeship pathways are emerging for those entering the field without traditional computer science backgrounds. Professional certifications including CISSP, CISA and CISM remain highly valued by employers, alongside cloud-specific security credentials as organisations migrate infrastructure to platforms operated from Ireland’s data centre ecosystem.

Median cybersecurity salaries in Ireland are competitive, with dedicated firms advertising median salaries around €75,000 in 2022 and senior roles commanding €100,000 or more. Entry-level positions typically start between €45,000 and €60,000. PwC’s 2025 Digital Trust Insights Survey found that 66% of Irish organisations planned to increase their cybersecurity budgets, reflecting the growing recognition that cyber resilience is a business imperative rather than a discretionary cost.

🔮 Challenges and Opportunities Ahead

The Cyber Ireland cluster, established in 2019 at Munster Technological University, has grown into the national representative body for the sector, uniting more than 160 member organisations including startups, SMEs, multinational corporations and educational institutions. In 2025, Cyber Ireland and its Northern Ireland counterpart, NI Cyber, signed a memorandum of understanding to drive cross-border collaboration. Their joint research, supported by InterTradeIreland, identified 42 cybersecurity companies already operating active offices on both sides of the border, demonstrating existing appetite for all-island cooperation in what is fundamentally a borderless challenge.

Ireland’s cybersecurity landscape faces several interconnected challenges. The skills gap remains acute, with demand for professionals consistently outstripping supply. Under-investment in cybersecurity research, development and innovation relative to Ireland’s exposure as a data hub has been flagged by industry groups. The delayed transposition of NIS2 has left a regulatory gap that the original NIS Directive, which covers only the most critical operators, cannot fully bridge.

At the same time, significant opportunities exist. Ireland’s 42 cybersecurity companies with active offices in both the Republic and Northern Ireland highlight the potential for enhanced cross-border collaboration through the all-island ecosystem. The harmonisation of EU cybersecurity laws and standards under NIS2 opens new markets for Irish companies that develop compliance tools, managed security services and regulatory technology. Enterprise Ireland has actively supported cybersecurity startups and scale-ups, with more than 60 indigenous cybersecurity companies currently operating in the market.

For Ireland’s broader digital economy, strengthening cybersecurity resilience is essential. The country’s fintech sector depends on robust security infrastructure to maintain trust and regulatory compliance. The growth of data centre infrastructure increases the attack surface that must be defended. As Ireland positions itself as a global technology hub, ensuring that its cybersecurity capabilities match its digital ambitions will be critical to sustaining investment, protecting citizens and maintaining the country’s reputation as a trusted location for sensitive data processing.
