Delivering an updated threat signature throughout the endpoint detection and response (EDR) system is the best way to take advantage of the security solution that uses a sandbox environment to execute zero-day software and collect indicators of compromise. An EDR system is a solution that monitors and analyzes the activities and behaviors of endpoints, such as computers, mobile devices, or servers, and detects and responds to potential threats. An EDR system can use threat signatures, which are patterns or characteristics of known malicious software or attacks, to identify and block malicious activities on endpoints. By delivering an updated threat signature based on the indicators ofcompromise collected from the sandbox environment, the organization can enhance its EDR system's ability to detect and prevent zero-day attacks that exploit unknown vulnerabilities.
