Change Auditor for Logon Activity
Active Directory user login reporting and detection of vulnerabilities and suspicious behavior in hybrid AD authentications. Increasing compliance regulations and security concerns make automated and reliable tracking of user logon and logoff activity essential. Unfortunately, most third-party tools are cumbersome to implement and don’t provide the level of auditing required to ensure adequate accountability of user actions. And system-provided auditing tools lack the ability to detect crucial vulnerabilities and exploits adversaries use to compromise networks. But Change Auditor for Logon Activity changes all that, proactively detecting authentication exploits, unearthing indicators of exposure, and providing Active Directory user login reporting to simplify forensic investigations.
With Change Auditor for Logon Activity, you can promote better security, auditing and compliance in your organization by capturing, alerting and reporting on all AD logon/logoff and Azure AD sign-in activity. Change Auditor for Logon Activity detects common Kerberos exploits, identifies NTLM vulnerabilities and provides easy-to-navigate forensics to determine who did what, and when.
Golden Ticket detection
Detect and alert on common Kerberos authentication vulnerabilities used during Golden Ticket / Pass-the-ticket attacks.
NTLM authentication auditing
Detect applications that are still using less secure NTLM authentications.
Active Directory user login report
Audit Active Directory account logons, from logon to logoff and all actions in between (when combined with other Change Auditor modules).
Hosted dashboard
