External Attack Surface Management (EASM)

"Know thyself."

External Attack Surface Management (EASM) represents a critical enterprise risk management capability that systematically identifies and catalogs internet-facing assets, providing the visibility essential for proactive risk mitigation.

In today's interconnected enterprise environments, every exposed asset—DNS records, servers, domains, web applications, and source code repositories—constitutes a potential risk vector requiring continuous oversight. For organisations of any substantial scale, the volume of these digital assets creates risk management complexity that demands systematic monitoring and governance.

Asset visibility forms the foundation of enterprise risk management. Organisations must maintain accurate inventories of their digital footprint to assess vulnerabilities, prioritize remediation efforts, and maintain robust security postures. This capability proves particularly critical during mergers and acquisitions, where inadequate due diligence of target organisations' attack surfaces can introduce substantial operational, financial, and reputational risks through the inheritance of compromised or vulnerable infrastructure.

Realize Security's EASM solution delivers rapid, comprehensive attack surface discovery and mapping capabilities across single or multiple organisations, providing executive leadership and risk management teams with actionable intelligence on their complete asset portfolio. These insights enable informed risk prioritization, facilitate targeted security investments, and support evidence-based resource allocation for vulnerability management and penetration testing initiatives.

Our non-intrusive assessment methodology enables organisations to gain immediate visibility into their risk exposure without operational disruption or extensive resource commitment. This approach particularly benefits enterprises operating under stringent change management protocols or constrained security testing windows, allowing risk assessment to proceed independently of traditional penetration testing cycles.
