A feature update of ESET Cloud Office Security version 747 has been released.

Changelog

We are committed to continuously improving our solutions and delivering cutting-edge features and enhancements. In this release, you can look forward to:

File Clawback

Following the success of our Email Clawback functionality, we have extended these capabilities to cloud-stored files. If a suspicious file is identified in your logs—whether it was uploaded via OneDrive, Google Drive, MS Teams, or SharePoint Online—you now have the option to remotely quarantine it for immediate inspection. This ensures that potentially malicious content is neutralized across your collaboration suites as quickly as it is in your inbox.

SPAM Reporting Made Easier

To help us refine our detection systems, we have also simplified the spam reporting process for your end users. When enabled in your Tenant Settings, a dedicated folder is automatically created in every mailbox. Users can simply move unsolicited emails into this folder, where they are then routed to our Anti-Spam team for analysis. To keep inboxes organized, these reported emails are automatically moved to the user's Trash folder five minutes after a successful submission.

GeoIP Info & Rule Condition

Context is essential for robust security, which is why we have integrated GeoIP metadata directly into your workflow. You can now view the sender's country of origin within the Email Details and include this data in your Syslog exports. Furthermore, we have added a new condition to Email Rules that allows you to automate actions, such as quarantining messages, based on the specific country from which an email was sent.

Domain Age & Rule Condition

Based on your feedback, we are introducing domain age information into Email Details as well as Email Rules. While parsing the creation date across all TLDs is not always possible, we provide a reliable fallback by displaying the date when the domain was first observed by ESET’s infrastructure. This allows you to determine whether a sending domain is newly created or well–established—and to build custom rules based on this metadata.

Rule Action to Prepend or Append HTML to Emails

You can now create rules to automatically prepend or append custom HTML content to incoming HTML emails. This is particularly useful for adding organization-wide legal disclaimers, security warning banners, or internal branding to specific message types.

Other Smaller Improvements

This release includes several smaller but impactful improvements to enhance your granular control. These updates include a new "Rules Applied" column in the Scan Logs, a "Spam Reason" condition for more specific Email Rules, and the ability to enable or disable individual detection sources within your Anti-Spam policy. We have also added a "State Field" to the Email Details and expanded the available optional fields for Syslog integration to provide more comprehensive reporting.
