New features and improvements in ARM

ARM connection to Dell EMC Isilon storage cluster

Storage clusters running OneFS provide real-time file system scanning and detailed logs of user activity.

FS Logga alert suppression

You can now apply file-type filters, including blacklist, whitelist, and RegEx options, to FS Logga alerts. A global blacklisted user setting has also been implemented for FS Logga alerts, giving administrators greater control over alert suppression.

User Management in the Web Client

Admin-only user management is enabled in ARM Web Client and you can now add, delete, and edit users and their roles.

SQL Server Express compatibility

ARM now supports the new 50 GB database limit introduced in SQL Server Express 2025 (version 17.x), allowing customer to scale further on the free database edition.

Compatibility with Exchange Server Subscription Edition

ARM support has been added for the Exchange Server Subscription Edition (Exchange SE), extending ARM compatibility.

Multifactor authentication in the Web Client

Multifactor authentication has been implemented in ARM Web Client and requires users to verify their identity through multiple components.

Group Policy Object Management

Users can create, configure, and monitor Group Policy Objects (GPO) in order to enforce consistent security and access policies.

Change Personal Information refactor

The Change Personal Information pop-up has been refactored to utilize a tabbed section layout, improving usability and readability.

Email subject line format

Email subject-line branding is now unified and the subject line format is customizable.

Performance improvements

• OneDrive scans now complete quicker, significantly improving overall performance.
