OT Security Consultant Career Path in Ireland

OT Security Consultants in Ireland earn between €75,000 and €145,000 depending on experience. OT Security Analysts at entry level earn €55,000 to €75,000. Experienced OT Security Consultants earn €75,000 to €110,000. Senior OT Security Consultants with IEC 62443 expertise and significant client engagement experience earn €110,000 to €145,000. Directors and practice leads in the field earn €145,000 to €190,000. The scarcity of OT security expertise means experienced contractors command very high day rates.

Global Industrial Cyber Security Professional (GICSP) from GIAC is the most recognised OT-specific certification in Ireland and the UK. IEC 62443 Cybersecurity Certificate (from ISA or TUV) is highly valued, particularly for regulatory-focused roles. Certified Information Systems Security Professional (CISSP) remains relevant as a broader security credential. Dragos and Claroty vendor certifications are valued for roles involving those OT security platforms. CISM is valued for OT security consultants moving toward advisory and management responsibilities.

Big Four consulting firms (Accenture Ireland, Deloitte Ireland, PwC Ireland) have growing OT security practices serving Irish and European clients. OT security platform vendors (Nozomi Networks, Claroty, Dragos) hire technical specialists and solution architects. Irish critical infrastructure operators (EirGrid, ESB Networks, Bord Gais Energy, Irish Water) hire in-house OT security professionals. System integrators working in energy and utilities also hire OT security consultants for project delivery.

The two common entry routes are: from an IT cybersecurity background (gaining OT knowledge through GICSP certification, IEC 62443 training, and project exposure), or from an operational engineering background (instrumentation, electrical, SCADA) combined with cybersecurity certifications. Both paths are valued; the rarest and most highly paid OT security specialists combine deep technical knowledge of both domains. Starting in IT security and seeking OT project assignments is the most practical route for most candidates in Ireland.
