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.

Large Retail Chain

Change Auditor object protection is a lifesaver. I have it set up to prevent changes to the ACLs on certain directories on our file servers, as well as to protect all administrative accounts. We've had pen testers come in and be very surprised that they could not get past the Change Auditor object protection.

With Change Auditor in place, we have not only the continuous monitoring we need to ensure smooth business operations, but a historian that tracks exactly what happened. The GDPR requires tight response times, which are pivotal and compulsory, and Change Auditor enables us to achieve compliance.

Mirco Destro CIO and IT Manager, AFV Beltrame Group Read Case Study

When something goes wrong, managers always ask IT for a report on what changed, and they need it now. Native tools didn’t enable us to respond to those requests quickly, especially since we are a limited IT staff. But with Change Auditor, we can start pulling up reports right away. That's really critical for us.
