class=\"arcad-lead\">\n                    Many financial centre entities outsource all or part of their internal audit to an external provider.

Many entities \u2014 in particular, modestly sized structures \u2014 do not have the headcount to maintain a full in-house internal audit team. Others are looking for specialised expertise that is difficult to recruit: cybersecurity, IT and resilience (DORA), anti-money laundering (AML\/CFT), and data. Outsourcing also brings a fresh perspective and independence from internal teams. Finally, it makes it possible to adjust resources to activity levels without bearing the cost of a permanent structure.\n                    <\/p>\n\n                <\/div>\n\n            <\/section>\n\n\n            <!-- 02 -->\n            <section class=\"arcad-section\">\n\n                <div class=\"arcad-number\" aria-hidden=\"true\">\n                    02\n                <\/div>\n\n                <div>\n\n                    <h2>What the Luxembourg framework permits (and what it does not permit)<\/h2>\n\n                    <p>\n                        This is the point that every manager should bear in mind. In Luxembourg, CSSF Circular 22\/806 on outsourcing (amended in 2025) lays down a clear rule: for internal control functions, including internal audit, <strong>only operational tasks<\/strong> may be outsourced to a service provider. However, responsibility for the function itself cannot be outsourced: it remains with the organisation.\n                    <\/p>\n\n                    <p>\n                        Specifically, the entity must internally designate a person responsible for the internal audit function, and the <strong>authorised direction<\/strong> (the managers approved by the CSSF) remain fully responsible, including for what is outsourced. Furthermore, the outsourcing of a critical or important function is subject to prior notification to the CSSF. In other words: you can delegate execution, never responsibility.\n                    <\/p>\n\n                <\/div>\n\n            <\/section>\n\n\n            <!-- 03 -->\n            <section class=\"arcad-section\">\n\n                <div class=\"arcad-number\" aria-hidden=\"true\">\n                    03\n                <\/div>\n\n                <div>\n\n                    <h2>The safeguards provided for by the CSSF<\/h2>\n\n                    <p>\n                        The framework precisely defines the relationship with the service provider in order to preserve independence and quality:\n                    <\/p>\n\n                    <ul>\n\n                        <li>\n                            The service provider reports to the member of the management body responsible for the internal control function.\n                        <\/li>\n\n                        <li>\n                            For the internal audit, he must <strong>furthermore<\/strong> to have direct access to the governing body in its supervisory capacity \u2014 the board \u2014 or, where applicable, to the chair of the audit committee.\n                        <\/li>\n\n                        <li>\n                            He carries out his work in accordance with the organisation\u2019s audit plan, documents each assignment and submits a report to the relevant internal manager, senior management and, where applicable, the audit committee.\n                        <\/li>\n\n                    <\/ul>\n\n                    <p>\n                        These requirements are not merely administrative red tape: they ensure that the service provider works for the board, and not solely for operational management.\n                    <\/p>\n\n                <\/div>\n\n            <\/section>\n\n\n            <!-- 04 -->\n            <section class=\"arcad-section\">\n\n                <div class=\"arcad-number\" aria-hidden=\"true\">\n                    04\n                <\/div>\n\n                <div>\n\n                    <h2>How to turn it into a real asset for the board and authorised management<\/h2>\n\n                    <p>\n                        Adhering to the framework is necessary, but not sufficient to create value.
