Customization

Dark Mode

Administrators can switch the theme of the Harmony Email & Collaboration Administrator Portal to Dark mode. It provides a dark background (instead of white) across the UI.

To enable or disable Dark mode:

1. Access the Harmony Email & Collaboration Administrator Portal.

2. Go to System Settings > Customization.

3. Under General, toggle Dark mode to On/Off.

4. Click Save and Apply.

Note - Turning Dark mode on/off does not impact the end-users and it is specific to the signed-in administrator. Each administrator can turn the Dark mode on/off for themselves.

Custom Logo

You can replace the Check Point logo to show your organization logo in the browser pages, email notifications, and reports Harmony Email & Collaboration sends to the administrators and users.

To add a custom logo:

1. Access the Harmony Email & Collaboration Administrator Portal.

2. Go to System Settings > Customization.

3. Select the Custom Logo checkbox.

   Note - The logo must have these properties.

   • File type is PNG

   • File size is less than 2 MB

   • Logo dimensions ratio is 1/2.5 px, 72 dpi (Horizontal version)

4. Upload the required logo(s).

   • To upload the logo compatible with dark backgrounds, under Logo for dark background, click Browse and select the relevant logo.

   • To upload the logo compatible with white backgrounds, under Logo for white background, click Browse and select the relevant logo.

   Notes:

   • If you upload only one logo, Harmony Email & Collaboration uses the same logo for dark and white backgrounds.

   • To have a clear logo compatible with the background, Check Point recommends using separate logos for dark and white backgrounds.

5. Select where you want to replace the Check Point logo:

   • To replace the logo in the Security Checkup report, enable the Security Checkup Report checkbox.

   • To replace the logo in the Daily Quarantine report, enable the Daily Quarantine Report checkbox.

   • To replace the logo in the browser pages presented to the administrators and users, enable the Browser pages checkbox.

   • To replace the logo in the email notifications, select the required option:

     • To replace the logo in all the email notifications sent to administrators and end users, enable the Admins and end users checkbox.

     • To replace the logo in all the email notifications sent only to administrators, enable the Admins only checkbox.

     • To replace the logo in all the email notifications sent only to end users, enable the End users only checkbox.

6. Click Save and Apply.

Customizing Retention Period of Emails

Harmony Email & Collaboration allows you to customize the email retention period based on the verdict of the security engines.

Default Retention Period of Emails

Verdict and Enforcement	Raw Email (Original email with attachments)	Email Meta Data (Attributes and data detected from the security scan)
Clean emails (Includes emails with re-written links in the email body)	14 days	14 days
Emails with modified attachments and emails that have cleaned (sanitized) attachments, removed as password-protected attachments, and re-written links	14 days	180 days
Emails containing threats but not quarantined (includes emails with phishing /spam / malware / DLP detection that are not quarantined)	14 days	180 days
Quarantined emails (includes manually quarantined emails)	180 days	180 days
Emails quarantined by Microsoft	180 days	180 days

Custom Retention Periods

To configure custom retention periods for raw emails:

1. Go to Security Settings > Customization.

2. Under Email Retention Settings, select Custom.

3. Based on the security engines' verdict and quarantine state, select the number of days you need to retain an email.

4. Click Save and Apply.

   Notes: Any changes to the retention period take effect within 24 hours and apply only to new emails. Emails get deleted at the end of the day (UTC time zone) of each retention period. Sometimes, it may take extra time for the delete action to be completed.

For details about the actions available during and after the retention period, see Available Actions on Emails During and After the Retention Period.

Auditing

Harmony Email & Collaboration audits all the changes to the retention period and adds them to the System Logs (System Settings > System Logs).
