What is AMSI?
The Anti-Malware Scan Interface (AMSI) is a Microsoft interface that allows applications and services to integrate with antivirus solutions for real-time malware scanning. It provides visibility into scripts and memory-based attacks.
AMSI is commonly used in Windows environments to detect threats such as fileless Malware and malicious scripts.
What is AMSI used for?
AMSI is used to improve detection of advanced threats that bypass traditional Antivirus (AV / NGAV) solutions. It enables Security Tool to inspect runtime behavior and identify Indicators of Attack (IOA).
Organizations rely on AMSI to strengthen endpoint security, particularly in conjunction with Endpoint Detection and Response (EDR) and Windows Security Center (WSC).
