Or coller un communiqu\u00e9 de presse dans un outil d\u2019IA est anodin, y coller du<br \/>\ncode non publi\u00e9 est un incident : seul le contexte permet de faire la diff\u00e9rence.<\/p>\n<p>Interdire en bloc n\u2019est pas plus efficace.

Sur cette base, six principes s\u2019appliquent.<\/p>\n<p><strong>1. Voir avant d\u2019interdire.<\/strong> Une politique sans visibilit\u00e9 sur les usages r\u00e9els reste th\u00e9orique.<br \/>\n<strong>2. Suivre la donn\u00e9e, pas seulement le fichier.<\/strong> Selon Mimecast, 90 % des pertes de donn\u00e9es li\u00e9es<br \/>\nau Shadow AI observ\u00e9es chez ses clients passent par un simple copier-coller.<br \/>\n<strong>3. Juger le risque au contexte.<\/strong> D\u2019o\u00f9 vient la donn\u00e9e, qui l\u2019envoie, vers quel outil : ces trois \u00e9l\u00e9ments<br \/>\np\u00e8sent plus que le texte seul.<br \/>\n<strong>4. Sensibiliser au moment de l\u2019action.<\/strong> Un rappel bref, qui indique l\u2019outil approuv\u00e9, change<br \/>\ndavantage les comportements qu\u2019une formation annuelle.<br \/>\n<strong>5. Bloquer de fa\u00e7on cibl\u00e9e.<\/strong> Le blocage strict se r\u00e9serve aux donn\u00e9es critiques et aux populations \u00e0<br \/>\nrisque.<br \/>\n<strong>6. Pr\u00e9voir une soupape.<\/strong> Une autorisation temporaire, justifi\u00e9e et trac\u00e9e, \u00e9vite de pousser au<br \/>\ncontournement.<\/p>\n<hr class=\"\" style=\"margin:0 auto 30px;\"\/>\n\n<h2>Comment Mimecast Incydr r\u00e9pond au Shadow AI<\/h2>\n<p>Mimecast Incydr traduit ces principes en contr\u00f4les concrets. Selon l\u2019\u00e9diteur, plus de <strong>10 000 tentatives<\/strong><br \/>\n<strong>d\u2019exfiltration<\/strong> vers des outils d\u2019IA non autoris\u00e9s sont observ\u00e9es chaque heure chez ses clients.<\/p>\n<h4>Une visibilit\u00e9 sur chaque copier-coller et chaque upload<\/h4>\n<p>Gr\u00e2ce \u00e0 un agent sur le poste et une extension de navigateur, Incydr capture les copier-coller et les<br \/>\nchargements de fichiers vers les outils d\u2019IA, sans connecteur pr\u00e9d\u00e9fini ni liste blanche. Les \u00e9quipes s\u00e9curit\u00e9<br \/>\nsavent quel document est sorti, qui l\u2019a envoy\u00e9 et vers quel outil. Les nouvelles applications d\u2019IA adopt\u00e9es<br \/>\npar les collaborateurs remontent automatiquement.<\/p>\n<h4>Une priorisation fond\u00e9e sur le contexte<\/h4>\n<p>Chaque \u00e9v\u00e9nement est \u00e9valu\u00e9 selon trois dimensions : le fichier, l\u2019utilisateur et la destination. Les analystes<br \/>\nse concentrent ainsi sur la petite part des usages r\u00e9ellement \u00e0 risque, plut\u00f4t que de crouler sous les<br \/>\nalertes.<\/p>\n<h4>Des contr\u00f4les adapt\u00e9s au niveau de risque<\/h4>\n<p>Incydr permet de graduer la r\u00e9ponse. Une courte vid\u00e9o de sensibilisation s\u2019affiche quand un salari\u00e9 colle<br \/>\ndes donn\u00e9es dans un outil non autoris\u00e9. Les donn\u00e9es issues des d\u00e9p\u00f4ts de code, du CRM ou des exports RH<br \/>\npeuvent \u00eatre bloqu\u00e9es, tout comme certains domaines d\u2019IA jug\u00e9s \u00e0 risque. Les salari\u00e9s sur le d\u00e9part et les<br \/>\nprestataires peuvent faire l\u2019objet de contr\u00f4les renforc\u00e9s, tandis qu\u2019une autorisation temporaire trac\u00e9e<br \/>\ncouvre les cas l\u00e9gitimes.<\/p>\n<h4>Un d\u00e9ploiement en quelques semaines<\/h4>\n<p>Mimecast d\u00e9crit une mont\u00e9e en puissance progressive : visibilit\u00e9 d\u00e8s le premier jour, sensibilisation en<br \/>\ntemps r\u00e9el apr\u00e8s deux semaines, blocage cibl\u00e9 des sc\u00e9narios critiques au bout d\u2019un mois. Incydr couvre les<br \/>\npostes g\u00e9r\u00e9s par l\u2019entreprise ; les appareils personnels rel\u00e8vent de l\u2019acc\u00e8s conditionnel ou d\u2019une solution<br \/>\nSSE<\/p>\n<hr class=\"\" style=\"margin:0 auto 30px;\"\/>\n\n<p>Le Shadow AI traduit un besoin r\u00e9el, pas une faute.
