FAQs

How does Cloud App Security ensure high availability?

All Cloud App Security service components maintain a stateless design. As such, they freely scale when volume increases. By default, all customer-facing services are set up redundantly behind the Windows Azure Load Balancer to ensure high availability.

How does Cloud App Security guarantee data privacy in a multi-tenant environment?

Cloud App Security does not store original content (email messages and files). Cloud App Security gets access to email and file content in cloud applications and processes it in memory, without storing it upon completion.

Will Cloud App Security impede access speed to messages and files?

Cloud App Security has no impact on performance when customers receive email messages, upload files to, or download files from cloud applications and services.

How can a customer with a trial license migrate the configurations on the trial Cloud App Security management console to the production management console after they purchase Smart Protection Complete with a full license?

After you re-log on to the Cloud App Security production management console, all the configurations are migrated and your license is updated.

How do employees log on to Cloud App Security using Internet Explorer on Windows Server?

Internet Explorer has different default settings on Windows Server and other Windows versions. Enable active scripts for the Internet zone to log on to Cloud App Security through Internet Explorer on Windows Server.

Is a customer who purchased Trend Micro Smart Protection Complete able to use Cloud App Security in a different site from the one dictated by the customer's registration key or activation code?

No, Cloud App Security serves a customer in the site based on the region or country dictated by the customer's registration key or activation code. To use Cloud App Security in a different site, the customer needs to apply for a new Customer Licensing Portal account with a new registration key corresponding to the site they want to use.

Why cannot I restore or delete an email message that has been quarantined by Cloud App Security?

When an email message is quarantined, it is stored in the quarantine folder created by Cloud App Security for further processing. Upon receiving a request to restore or delete the message, Cloud App Security fails to do so if it cannot locate the message in the quarantine folder. When the issue occurs, check whether this message was moved out of the quarantine folder to somewhere else. You can go to Quarantine and view the Mail Location column to find the quarantine folder of the message.

When and how does Cloud App Security remove a service account for the Microsoft 365 services if the customer's license expires?

If your license has reached the end of the grace period, Cloud App Security disables your CLP account. This means that the Cloud App Security management console is no longer accessible and Cloud App Security does not protect your services any more.

After 30 days of the grace period, Cloud App Security automatically removes your CLP account.

Microsoft removes the SharePoint user profiles 30 days after service account removal. There is still remaining data created for Cloud App Security that requires manual cleanup. For details, see Changes made by Cloud App Security.

How can a customer enable multi-factor authentication (MFA) on the Exchange Online and SharePoint Online Delegate Accounts after automatic access grant?

On August 2, 2019, Microsoft implemented a mandatory Multi-Factor Authentication (MFA) policy for all partners re-selling Microsoft 365 licenses to end users. The policy requires all administrator accounts in the Cloud Solution Provider (CSP) tenant to have Multi-Factor Authentication.

How can a customer specify a name and location when downloading quarantined items, instead of using the default name?

When you download quarantined items through a web browser, Cloud App Security automatically generates a file name in a default format: <timestamp>_<email subject or file name>_<affected user's name>.

To customize the file name and location, configure the Downloads settings of your browser to always ask where to save each file before downloading.

Why does Cloud App Security still quarantine or delete email messages even when all policies are in the Monitor Only mode?

In Cloud App Security, the default Monitor Only policy takes effect only at the policy level. When requested to quarantine or delete an email message by integrated products or the Cloud App Security Threat Mitigation APIs, Cloud App Security quarantines or deletes the email message even if the default Monitor Only policy is enabled.

To ensure that Cloud App Security does not take any actions other than "Pass" when the default Monitor Only policy is enabled, perform the following:
