Rather than filtering outbound flows, it continuously monitors open and closed sources where your organization&#8217;s data might appear.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">This approach relies on two complementary disciplines. EASM (External Attack Surface Management) is a method for continuously mapping and monitoring an organization&#8217;s external exposure: exposed assets, accessible services, vulnerabilities visible from the internet. It reduces the attack surface before it is exploited. Data leak detection is the active monitoring of sources where organizational data may have been disclosed: dark web, paste sites, public repositories, specialized forums, compromised databases.<\/p><p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Together, these two disciplines answer a question DLP tools never ask: what can your attackers already see about you?<\/p><table style=\"width: 100%; border-collapse: collapse;\"><tbody><tr><th style=\"background: #09025F; color: #fff; padding: 8px; text-align: left;\">Criterion<\/th><th style=\"background: #09025F; color: #fff; padding: 8px; text-align: left;\">Internal DLP<\/th><th style=\"background: #09025F; color: #fff; padding: 8px; text-align: left;\">EASM + Data leak detection<\/th><\/tr><tr><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Monitored perimeter<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Internal network and endpoints<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">External sources, dark web, public repositories<\/td><\/tr><tr><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Detection nature<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Preventive (blocks before the leak)<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Detective (identifies what has already leaked)<\/td><\/tr><tr><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Third-party visibility<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Limited<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Extended to the supply chain<\/td><\/tr><tr><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Detection timing<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Real-time on internal flows<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Continuous across open and closed sources<\/td><\/tr><tr><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Main blind spot<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Data already outside the perimeter<\/td><td style=\"padding: 8px; border-bottom: 1px solid #e0e0e0;\">Unmonitored internal flows<\/td><\/tr><\/tbody><\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5a10691 syd-sticky-section-no elementor-widget elementor-widget-heading\" data-id=\"5a10691\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">NIS2 and DORA: A Monitoring Obligation That Extends Beyond Your IT Systems<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9973ed1 syd-sticky-section-no elementor-widget elementor-widget-text-editor\" data-id=\"9973ed1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The NIS2 directive, currently being transposed into French law following its adoption by the Senate in March 2025, requires essential and important entities to continuously monitor their information systems and maintain incident detection capabilities. It also mandates reporting to ANSSI within 24 hours of a significant incident, along with formal management of third-party supplier risks. These obligations make external detection necessary, not optional.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The DORA regulation (Digital Operational Resilience Act), applicable since January 2025 to financial entities, requires an ICT contracts register, operational resilience testing, and formalized management of third-party risks. Monitoring the external attack surface directly addresses these requirements by identifying exposures from the supply chain before they are exploited.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">For a mid-sized organization subject to NIS2 or DORA, outsourcing data leak detection to a French provider without offshoring is not only an operational advantage.
