Diploma in Validation of Critical Communication Networks — studying from Ireland
Ireland maintains a small defence force, the Defence Forces, which operates its own engineering corps and equipment maintenance capabilities. Defence procurement and development are handled through the Department of Defence, while much of the wider defence-related industrial activity involves dual-use technologies, electronics and communications systems supplied by domestic and international firms. Engineers in this area typically work on land vehicle maintenance, military communications, protective equipment and systems integration. Policy and procurement are governed by national and European frameworks, including EU defence initiatives.
Fees for Ireland: €1,790 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Which Irish bodies oversee defence engineering and does a private qualification count?
Defence in Ireland is overseen by the Department of Defence, and the Defence Forces run their own training and technical structures. Engineers Ireland sets general professional engineering standards. SEIUM's qualifications are private and not state-awarded, and they are not accredited by any national body, so recognition for any defence-related role is decided by the relevant authority or employer.
Do Irish defence and land-systems employers hire people with private online qualifications?
Irish defence-related hiring is limited and often subject to security vetting and specific qualification requirements, so employers set their own criteria. A private online qualification may be taken into account alongside experience, but we cannot say how any employer will view it or guarantee any result. Check requirements for particular roles directly.
Can I study this from Ireland while working, and what is the workload?
Yes, the programme is 100% online and taught in English, so you can study from home without travel or a student visa. Master's programmes total 1,900 hours, postgraduate diplomas 800 and specialist courses 300. Each student has an assigned technical tutor, fees can be paid in instalments, and employer sponsorship may be possible. Plan your weekly hours realistically around your job.

How you'll learn
100% online learning on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Wireshark, iPerf3, GNS3, Spirent TestCenter and Keysight IxNetwork, in free, academic or evaluation versions. Practical work is based on real procedures: load and latency testing on a critical network, failover validation and network segmentation audits. Assessment is continuous by module plus the final project.
Standards covered: IEC 62443, ISO/IEC 27001, Directive (EU) 2022/2555 NIS2, ITU-T Y.1564, IETF RFC 2544, ETSI EN 300 392, 3GPP TS 22.179.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
