Email Security.cloud Infrastructure Maintenance: March 18-24, 2026

Broadcom will perform planned updates to the Email Security.cloud service to change the PBE Advanced TLS delivery option. This update affects the EMEA and NAM regions.

Timing

Maintenance is scheduled to begin on March 18, 2026, and will be completed by March 24, 2026. All work will be conducted during off-business hours according to the following regional schedule:

• NAM: All maintenance will occur between 08:00 and12:00 UTC
• EMEA: All maintenance will occur between 18:00 and 00:00 UTC

What customers should expect

Following this maintenance, for customers using one of the PBE Advanced policies that specify the use of TLS, if the recipient mail server supports TLS, the messages will no longer take an unnecessary hop through Echoworx to deliver over TLS and will instead be delivered directly to the recipient over TLS from the Email Security Service.

NOTE: This new behavior will only occur if the action in the data protection rule mandates TLS failing over to portal or attachment encryption. If the data protection policy action does not mention TLS, then emails will continue to be delivered as before. You can check to see if TLS is mentioned in your data protection policy by reviewing the administrator's email address. If the email address contains “TLS”, then this new behavior will be applied. Also note that this behavior does not affect PGP Advanced encryption.

As a result:

• Echoworx portal: TLS-encrypted messages that match the PBE Advanced TLS policy will no longer appear in the Echoworx portal; only non-TLS traffic will be visible.
• Track and Trace results: TLS-encrypted messages that match the PBE Advanced TLS policy will no longer be reported twice. Customers will now see a single instance of these messages.
• “Encrypted via TLS” banner: If Echoworx was adding an “Encrypted via TLS” banner to messages, that banner will no longer be applied to TLS-encrypted messages that match the PBE Advanced TLS policy.

Impact

No service outage or degradation is expected during the maintenance window.

The scheduled maintenance is now underway. We'll keep you updated on our progress.

Broadcom is performing updates to its Email Security.cloud service. This release includes minor fixes to the email scanning infrastructure related to TLS verification before delivery for Echoworx, which will impact the EMEA and NAM regions.

Timing

The maintenance will begin on March 18, 2026, with a completion date of March 24, 2026, and will be conducted during off-business hours only. See timing for each region below:

• NAM: All maintenance will occur between 08:00 and 12:00 UTC.

• EMEA: All maintenance will occur between 18:00 and 00:00 UTC.

Impact

No customer impact is expected from this maintenance and all aspects of our service are expected to function as normal.
