External Attack Surface Management (EASM) refers to the continuous process of identifying, monitoring, and securing all of an organization’s publicly accessible digital assets, such as websites, cloud services, and exposed databases. EASM tools and practices help organizations discover unknown or forgotten assets, assess their vulnerabilities, and reduce the risk of cyberattacks by closing security gaps. This proactive approach is essential as businesses expand their online presence, making it harder to keep track of what is visible and potentially exploitable by attackers on the internet.
