Selon <a href=\"https:\/\/www.agoria.be\/fr\/services\/expertise\/digitisation\/cybersecurity\/le-secteur-cyber-belge-va-doubler-en-5-ans-4000-experts-sont-recherches\" target=\"_blank\" rel=\"noreferrer noopener\">une r\u00e9cente analyse d'Agoria<\/a>, le chiffre d'affaires a bondi de 65% entre 2021 et 2024, passant de 1,58 \u00e0 2,61 milliards d'euros. Le secteur pr\u00e9voit m\u00eame un doublement d'ici 2030 avec une croissance annuelle de 15,9%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ces investissements massifs t\u00e9moignent d'une prise de conscience collective. Pourtant, avec 275 cyberattaques par jour en moyenne en Belgique et une entreprise sur quatre touch\u00e9e en 2024, un angle mort persiste dans de nombreuses organisations : <strong>le patrimoine applicatif sur mesure d\u00e9velopp\u00e9 au fil des ann\u00e9es<\/strong>.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group top-divider has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\" style=\"border-top-color:#e8e8e8;border-top-width:1px;margin-top:0;margin-bottom:0;padding-top:var(--wp--preset--spacing--large);padding-bottom:var(--wp--preset--spacing--large)\">\n<h2 class=\"wp-block-heading\">Comprendre le d\u00e9fi des applications sur mesure<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Vos applications m\u00e9tier ont \u00e9t\u00e9 d\u00e9velopp\u00e9es avec soin, souvent pour r\u00e9pondre \u00e0 des besoins sp\u00e9cifiques que les solutions du march\u00e9 ne couvraient pas. C'est pr\u00e9cis\u00e9ment parce qu'elles sont critiques qu'elles m\u00e9ritent une attention particuli\u00e8re en mati\u00e8re de s\u00e9curit\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prenons un exemple concret : une application de gestion d\u00e9velopp\u00e9e en 2015 pour le secteur public. \u00c0 l'\u00e9poque, elle r\u00e9pondait parfaitement aux besoins et aux standards de s\u00e9curit\u00e9. Aujourd'hui, les d\u00e9veloppeurs originaux ont \u00e9volu\u00e9, les frameworks utilis\u00e9s ne re\u00e7oivent plus de mises \u00e0 jour, et les pratiques de s\u00e9curit\u00e9 ont consid\u00e9rablement progress\u00e9. L'application fonctionne toujours, mais sa surface d'attaque s'est \u00e9largie sans que personne ne s'en aper\u00e7oive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cette situation est loin d'\u00eatre rare. Elle refl\u00e8te une r\u00e9alit\u00e9 : <strong>le contexte de s\u00e9curit\u00e9 \u00e9volue plus vite que nos applications<\/strong>, et nous avons besoin d'une approche pour combler cet \u00e9cart sans tout reconstruire.<\/p>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-b56e0895
