IT Companies in Ireland: Full List
Approximately 34,878 real businesses classified under Information and Communication in Ireland, with officer, shareholder and beneficial ownership records sourced directly from official government registries.
Approximately 34,878 real businesses operate in the Information and Communication sector across Ireland. Software and telecom companies are the sector most likely to have four holding-company layers before you reach a real person — and it is rarely for tax reasons alone. Staged venture-capital and private-equity investment rounds, plus standard tax-efficient group structuring, both push ownership chains further here than in almost any other sector. The sector covers software publishing, IT services, telecom network operation, broadcasting, and publishing, and beneficial-ownership resolution is disproportionately relevant precisely because of that depth.
91 companies in this sector are indexed on Zavia so far, part of a continually growing dataset.
Beneficial-ownership and registration rules for Information and Communication companies in Ireland follow the same national framework as every other sector there.

Analysis
What this data actually tells you
Information and Communication in Ireland sits in a genuine legal gap: NIS2 has not yet been transposed into Irish law, despite an original EU deadline of 17 October 2024. In July 2026, the European Commission referred Ireland to the Court of Justice of the European Union specifically for failing to notify full transposition — a real, escalated infringement action, not a routine delay. The National Cyber Security Bill (NCSB) is Ireland’s vehicle for eventual transposition, and would also give the National Cyber Security Centre (NCSC) its first statutory legal foundation, which it currently lacks.
In anticipation, the NCSC published governance guidance for management boards and senior executives on 7 July 2026, even though the underlying legal obligations aren’t yet in force. Once transposed, scope would split into essential entities (250+ full-time employees and €50 million turnover) and important entities (50+ employees and €10 million turnover). For verification, an Irish IT or digital-infrastructure counterparty currently has no binding NIS2 obligation under Irish law at all — its actual compliance posture, if any, is voluntary preparation ahead of a still-unenacted bill, not a live legal requirement.

Who uses Ireland information and communication ownership data
The three checks this sector's data is most often run for.
NIS2 non-transposition status check
Ireland has not yet transposed NIS2 into national law — in July 2026 the European Commission referred Ireland to the Court of Justice of the EU for failing to notify full transposition, well past the original 17 October 2024 deadline, meaning the underlying Irish legal obligation still doesn’t formally exist.
National Cyber Security Bill tracking
The National Cyber Security Bill (NCSB) is Ireland’s vehicle for transposing NIS2 and would give the NCSC its first statutory foundation — its passage is a real, dated legislative event worth tracking rather than assuming NIS2 obligations are already enforceable in Ireland.
Size-threshold scope check
Once in force, NIS2 scope in Ireland would split into essential entities (250+ employees, €50 million turnover) and important entities (50+ employees, €10 million turnover) — a company’s in-scope status depends on checking these specific thresholds, not assuming from sector alone.
