Companies are increasingly recognizing the need to understand their entire Internet-facing architecture as hackers exploit vulnerabilities in often-overlooked areas through bug bounty programs. This has led to a shift from traditional vulnerability management to a more comprehensive approach known as External Attack Surface Management (EASM). EASM involves continuously monitoring for vulnerabilities and anomalies across all digital interfaces, including those not directly controlled by the company, such as third-party services and abandoned subdomains. By mapping out and analyzing the attack surface, organizations can identify potential security gaps, such as exposed ports, leaked credentials, and misconfigured services, before they are exploited. Tools like Detectify Surface Monitoring leverage automated reconnaissance techniques and crowd-based hacker research to assess these vulnerabilities, allowing companies to prioritize resources and strengthen security measures. This holistic approach enables a proactive defense strategy, integrating vulnerability scanning with surface monitoring to uncover and address both known and unforeseen security threats.
