Unusual logon

This feature provides basic detection of unusual logons and brute-force attacks. This helps you identify suspicious login activity early and reduce the risk of system compromise.

Cloud threat detection

Detects anomalous use of cloud products based on user behavior analysis. For example, it can identify when an attacker uses a compromised AccessKey to purchase a large number of ECS instances for crypto-mining.

AccessKey pair leak

This feature scans public source code on platforms like GitHub in real time for exposed user credentials. It identifies whether your AccessKey pair has been leaked and generates an alert, helping you promptly discover and handle a potential AccessKey pair leak.

AccessKey pair leak detection

Compliance check

Provides compliance checks for standards such as MLPS 2.0 and ISO 27001. This helps you meet compliance assessment requirements and achieve certifications.
