Monitoring cloud services used by developers, SaaS solutions adopted by business units, and other cloud-based assets is crucial for security[2].

Ensuring the security of mobile applications to prevent unauthorized access or data breaches is essential in EASM[4].

Monitoring Internet of Things (IoT) devices like smart cameras and sensors to prevent unauthorized access or DDoS attacks is vital for overall cybersecurity[4].

Securing API endpoints that act as gateways to sensitive data and business logic from exploitation is critical in EASM[4].

Publicly accessible network hardware such as routers, switches, or load balancers can be vulnerable entry points for attackers if not properly secured[4].

Monitoring employee endpoints like laptops, desktops, and mobile devices to prevent insider threats or unauthorized access is essential for comprehensive EASM[4].

Protecting domain names from brand infringement, typosquatting, and other malicious activities is crucial for maintaining brand integrity and security[2].

Monitoring social media platforms for potential threats like phishing attacks or brand impersonation is important in EASM[2].

Ensuring the security of digital properties on marketplaces and app stores to prevent fraudulent activities or unauthorized access is a key aspect of EASM[2].

The absence of a traditional network perimeter complicates EASM as organizations now have numerous endpoints and assets spread across various locations and devices, making it challenging to monitor and secure the entire attack surface[1].

With assets hosted beyond firewalls or in the public cloud, organizations struggle to maintain real-time visibility into their external attack surface, leading to gaps in monitoring and protection[1].

Organizations rely on third-party products, services, and capabilities, including data, infrastructure, and code, which can introduce additional complexities and vulnerabilities into the attack surface that need to be considered in EASM strategies[1].

The continuous deployment of new technologies and services for competitiveness inadvertently expands the attack surface, making it challenging to keep track of all assets and their associated vulnerabilities[2].

The diverse range of assets, including websites, applications, IoT devices, APIs, and network infrastructure, poses a challenge in effectively managing and securing each asset against potential threats[2].

Ensuring that EASM solutions can scale with the organization's growth and adapt to changing digital landscapes is crucial but can be a challenge due to the dynamic nature of cyber threats[3].

Identifying and prioritizing vulnerabilities across the external attack surface for remediation can be complex, requiring organizations to effectively assess risks and allocate resources for mitigation[3].

Developing effective incident response plans tailored for external attacks is essential but can be challenging without a clear understanding of the organization's external attack surface and potential threats[3].

Conducting thorough risk assessments across subsidiaries, supply chains, third-party vendors, and M&A activities to gain visibility into all digital assets for a comprehensive risk management strategy can be time-consuming and complex[3].

Ensuring compliance with industry regulations while managing the external attack surface adds another layer of complexity as organizations need to align EASM practices with regulatory requirements for data protection and cybersecurity[4].

EASM solutions continuously monitor an organization's external attack surface, identifying potential vulnerabilities, misconfigurations, and exposures that could be exploited by threat actors[1].

By conducting comprehensive asset discovery and classification, EASM helps organizations gain visibility into all internet-facing digital assets containing sensitive data, such as personally identifiable information (PII), protected health information (PHI), and trade secrets[2].
