What Is External Attack Surface Management (EASM)?

External Attack Surface Management (EASM) refers to the processes, technology and professional services deployed to discover external-facing enterprise assets and systems that may present vulnerabilities. ​

 

EASM has been identified as the top security trend in Gartner’s “Top Security and Risk Management Trends for 2022”. Specifically, Gartner stated that “Enterprise attack surfaces are expanding. Risks associated with the use of cyber-physical systems and IoT, open-source code, cloud applications, complex digital supply chains, social media and more have brought organizations’ exposed surfaces outside of a set of controllable assets. Organizations must look beyond traditional approaches to security monitoring, detection and response to manage a wider set of security exposures. Digital risk protection services (DRPS), external attack surface management (EASM) technologies and cyber asset attack surface management (CAASM) will support CISOs in visualizing internal and external business systems, automating the discovery of security coverage gaps.”

Also, awareness of the organization's External Attack Surface is the #1 best practice recommended by CISA's Ransomware Guide.​

C2SEC has been recognized in both 2021 and 2022 as one of the leading providers by Gartner. This recognition is a validation of C2SEC’s continuous innovation and leadership in providing critical EASM SaaS solutions.
