External Attack Surface Management

External Attack Surface Management Reviews and Ratings

What is External Attack Surface Management?

External attack surface management (EASM) refers to the processes, technology and professional services deployed to discover internet-facing enterprise assets and systems and exposures that could be exploited by malicious threat actors. EASM is useful in identifying unknown assets and providing information about the organization’s systems, cloud services and applications that are available and visible in the public domain and therefore can be exploited by an attacker/adversary. This visibility can also be extended to the organization’s subsidiaries or third parties. EASM are most commonly cloud-based products and services but can also be delivered ‘as a service’. EASM appeals to security operations functions involved with penetration testing, vulnerability management and threat hunting who want better visibility of their internet-facing assets to complement their threat and exposure management program.
