Internal Audit

What this service delivers.

We deliver internal audit services across the Luxembourg financial and asset management ecosystem, including AIFMs, UCITS ManCos, specialised PSFs, depositaries, and fintech operators subject to CSSF oversight.

Our work provides boards, authorised managers, audit committees, and internal audit functions we partner with a clear view of control environment adequacy and effectiveness, operational resilience, delegation oversight, and regulatory alignment.

We translate complex operating models and regulatory expectations into clear conclusions and priorities that directly inform governance and decision‑making.

From assessment to execution, delivering pragmatic and actionable outcomes.

We deploy senior professionals with deep understanding of Luxembourg AIFM, ManCo, PSF, and service‑provider operating models. We assess risks and control reality quickly, accurately, and without a learning curve.

Clarity, brought

We convert observations into sharp, materiality‑driven conclusions that highlight root-causes, interconnected risks, and that can be acted on.

Pragmatism, delivered

We focus on what truly matters for your business, regulatory expectations and operational integrity. Our work avoids theoretical issues and is grounded in your business model, culture, and organisational reality.

Execution, owned

We manage the full audit cycle, wherever you need us, for and with you, from risk assessment and planning to execution, reporting, and follow‑up. Experience guides us to focus where it matters most.

Results, achieved

We support remediation by agreeing realistic actions and plans with accountable properly identifies owners and following through until closure, ensuring issues are not only identified but effectively resolved.

Service scope

What this service
covers.

We assume full responsibility for the internal audit function, from set-up to reporting, delivering a complete risk-based audit tailored to your business, aligned with regulatory and sector‑specific expectations.
Execution is fully senior, allowing boards and senior executive to rely on an internal audit function that understands their risk universe, operating model, delegation framework, and regulatory exposure.
Reporting is concise, risk‑based, and tailored to the decision‑making needs of boards, audit committees and senior management.
Full ownership of the internal audit function, from risk assessment and audit planning to execution, reporting, and follow‑up, ensuring independence, continuity, and true value-added partnership.
 
We reinforce existing internal audit teams where additional senior and/or local expertise, specialised knowledge, or temporary capacity is required.
Our involvement enhances quality, methodological discipline, and regulatory alignment, without disrupting governance lines or internal ownership.
We integrate seamlessly with existing teams while maintaining high standards of quality and consistency.
Where specialised or benchmark insight is required, we selectively integrate recognised subject‑matter experts (e.g. ICT, cyber, risk, valuation, AML, etc) under our direction, ensuring depth of analysis without diluting accountability or independence.
This model strengthens the function while preserving governance structure, internal ownership, established stakeholder relationships and accountability.
We conduct targeted reviews on complex or sensitive areas such as valuation, AML/CTF, ICT and cyber controls, or delegation oversight.
These deep dives are designed to provide boards, senior executives and internal audit functions with clarity on risk landscape, materiality, root causes, and priority actions, particularly following supervisory feedback, operational concerns, or strategic change.
When missions require deeper technical or market‑specific expertise, we complement your team with trusted subject‑matter specialists, fully aligned with your methodology and governance standards.
The scope is 100% tailored to our specific needs and areas of concern and is designed to bring a clear, structured basis for informed decision‑making in complex or sensitive situations.
We perform independent, objective evaluations of internal audit functions against IIA Standards and professional practices, while also integrating CSSF expectations.
The assessment highlights strengths, gaps, and maturity, and provides practical recommendations in line with best market practices to enhance performance, and effectiveness.
Boards, senior management, and internal audit teams receive a clear, forward-looking view of whether the function is structurally equipped to support the business and address emerging risks.
Following regulatory injunctions or on-site inspections, we structure remediation reports that translate observations into clear and effective actions.
Each review is aligned to regulatory references, control expectations, and implementation feasibility, enabling effective prioritisation and follow‑up.
This ensures remediation is adequate, well‑documented, and capable of withstanding regulatory challenge.
We act as a senior sparring partner to internal audit teams by refining methodologies, strengthening risk assessments, supporting with scoping what matters, reviewing working papers, and enhancing reporting quality, on an ad hoc or ongoing manner.
Support is hands‑on, senior‑led, and grounded in real cases and local market practice, improving judgment, challenge capability, positioning and regulatory alignment.
We provide access to senior subject‑matter expertise as needed to strengthen judgment on complex topics while preserving internal ownership and decision‑making.
We help you understand local particularities and requirements and carry out your mandate in alignment with your methodologies, group culture and business, and thus to increase your overall internal audit function effectiveness.
We design and establish internal audit functions for newly licensed entities or organisations upgrading their governance framework.
This includes defining the mandate, drafting charters, establishing methodologies, clarifying reporting lines, and embedding regulatory requirements.
The result is a fully operational, effective internal audit function that can be internalised or outsourced on an ongoing basis.
