Yamasuki was founded on a simple but frustrating observation: too many mid-market organisations face serious EU regulatory obligations with no practical path to address them — and the advisers who could help are either too expensive, too generalist, or too vendor-biased to be useful.
We built Yamasuki to be different. Independent. Fixed-fee. Genuinely expert. And sized for the organisations that actually need help — not the ones that can already afford a Big Four retainer.
Yamasuki Advisory was founded in Ireland with a clear mandate: to make elite EU compliance and cybersecurity advisory accessible to the organisations that need it most — mid-market companies operating in, or supplying to, regulated sectors across Ireland and Europe.
The founding insight was straightforward but consistently underserved. A 200-person SaaS company supplying three Irish banks faces the same DORA obligations as a 10,000-person enterprise — but has none of the internal compliance infrastructure to address them. A manufacturing company in Cork with SAP S/4HANA faces NIS2 as an important entity — but their IT team has never heard of Segregation of Duties. A FinTech about to close a Series B needs a full compliance framework in 8 weeks — but the Big Four want a 6-month engagement at €500 per hour.
Yamasuki was built to close that gap. Fixed fees. Named advisers. Board-ready outputs. No vendor conflicts. No rotating teams of junior consultants. Just expert advisory, delivered at a price that makes sense for the organisations that actually need it.
The name Yamasuki reflects a Japanese philosophy of purposeful mastery — the relentless pursuit of doing one thing exceptionally well. For Yamasuki, that one thing is bridging the gap between the technical reality of security and governance, and the commercial and regulatory decisions that boards and leadership teams need to make.
Mid-market organisations face enterprise-grade EU compliance obligations but cannot access enterprise-grade advisory at enterprise prices. Yamasuki prices at mid-market budgets without compromising on the quality of output.
Ireland sits at the intersection of EU regulatory requirements and an internationally-oriented business community — home to FinTechs, SAP-dependent manufacturers, pharma suppliers, and professional services firms, all navigating DORA and NIS2 with limited internal capability.
Every recommendation we make must be one we would make if we were the client's CFO — not their technology vendor, not their auditor, not their insurer. Vendor-independent. Outcome-driven. Always.
Yamasuki's advisory capability is built on deep technical expertise combined with practical regulatory knowledge. Our engagements are delivered by named senior advisers — not juniors supervised remotely.
Deep working knowledge of DORA (2022/2554), NIS2 (2022/2555), the EU AI Act, and their Irish transposition. Includes Central Bank of Ireland ICT risk guidelines and ENISA implementation guidance.
Specialist expertise in SAP S/4HANA role design, SAP EWM access management, Segregation of Duties conflict remediation, and SAP GRC module implementation. One of the scarcest skill combinations in the advisory market.
ISO 27001 Lead Auditor qualified. Practical experience designing and implementing ISMS frameworks, conducting internal audits, and preparing organisations for certification.
Governance, Risk and Compliance framework design across multiple sectors — financial services, manufacturing, healthcare, and professional services. Board-level governance and risk reporting architecture.
Data-flow governance for AI systems, LLM risk assessment, EU AI Act risk classification, and privilege boundary enforcement for AI-connected enterprise systems.
Pre-acquisition technical security risk assessment, post-merger integration security mapping, and technology debt quantification for private equity and corporate transaction teams.
Four principles govern every Yamasuki engagement. They are not marketing copy. They are the conditions under which we accept and deliver work.
We hold no technology partnerships, no referral arrangements, and no reseller agreements — with any vendor, ever. Our recommendations reflect what is best for the client's organisation. Nothing else influences them.
If an engagement would not generate meaningful value for a client, we say so before they pay for it. We do not manufacture scope to increase fees. If a smaller engagement would serve the client's needs, we recommend it.
Every deliverable is designed to be understood and acted on at board or executive level — not just by the IT team. Bridging technical security and commercial decision-making is the core of what we do.
Every engagement is priced at a fixed fee confirmed before work begins. We do not use hourly billing. The client always knows the total cost before a single hour of advisory time is spent.
Independence is a word used freely in professional services and rarely delivered on in practice. For Yamasuki, it has a specific operational meaning.
