Best Cybersecurity Companies in Ireland
The 110 best Cybersecurity companies in Ireland in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Fenergo.
Ireland's Cybersecurity sector has a directory worth bookmarking: 110 companies tracked, $608M in disclosed funding, and one unicorn already in the mix. Fenergo leads the pack at $181M raised, Tines follows at $146M, and the rest of the field stretches from Evervault's $22M down to early-stage bets like Mirror Security and Overcast HQ at $2M each. Enterprise Ireland, Sure Valley Ventures, and Act Venture Capital are the names showing up most in cap tables, which tells you something about where the conviction sits. Cybersecurity market researchers forecast significant growth peg the global market at roughly $72.5B in 2023, growing at a 10.99% CAGR, driven by tightening government regulations and companies' deepening dependence on internet infrastructure.
What I find interesting this quarter is the thematic drift happening above the application layer. OpenAI's cybersecurity action plan signals that AI is rewriting threat assumptions fast, and InstaSafe's Europe expansion push confirms that vendors from outside the region see Ireland's corridor as worth targeting. So the competitive pressure on these 110 companies isn't just local. Coverage themes have shifted toward drone warfare, aerial bombardment, and anti-satellite vectors, and that's pulling enterprise security budgets in directions traditional endpoint vendors weren't built for. If you're mapping this space, the funding momentum here is real but concentrated.
