It ensures that if you get breached, the blast radius is contained, so the networks don&#8217;t lose sleep. It is a baseline for liability shift, not a strategy for fraud prevention.<\/p>\n\n\n\n<p><strong>The infrastructure trade-off:<\/strong><\/p>\n\n\n\n<p>The moment you touch a raw Card Number (PAN), your operational overhead 10x&#8217;s. You are now in &#8220;Scope.&#8221; This means your database, your logs, your VPC, and even your office Wi-Fi could technically be under the auditor&#8217;s lens.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The winning move:<\/strong> Don\u2019t touch the data. Use <strong>tokenization<\/strong>.<\/li>\n\n\n\n<li><strong>The systemic benefit:<\/strong> You shift the liability to a specialized third party.
