In security and cybersecurity, a Zombie API (Application Programming Interface) typically refers to an API that was once active and utilized but is no longer officially maintained or monitored by the organization. These abandoned or "zombie" APIs can pose significant security risks as they may still be accessible. Still, they lack the necessary security updates and controls, making them vulnerable to exploitation by malicious actors. Zombie APIs are a potential backdoor for cyberattacks and data breaches and should be identified and addressed to ensure the overall security and compliance of an organization's digital assets.

ThreatNG is a comprehensive solution encompassing External Attack Surface Management (EASM), Digital Risk Protection (DRP), and Security Ratings, which assists organizations in mitigating the risks associated with Zombie APIs. Systematically identifying and evaluating Web Application APIs fortifies the organization's external digital presence, seamlessly aligning with internal security strategies. This integrated approach reinforces API security, reducing the risk of vulnerabilities posed by unattended or abandoned APIs and enhancing overall safety and compliance while complementing the organization's internal security framework.
