An emerging trend in digital transformation efforts has been the rise of low-code development platforms. Of course, these low-code platforms must be grounded in best-of-breed governance capabilities which include security and compliance features. Without strong governance, the full benefits of low-code development cannot be realized. It’s only natural that any low-code platform chosen by an organization must have strong security and compliance capabilities. Microsoft has developed the Power Platform which includes Power Apps, Power Automate, Power Virtual Agents, and Power BI to serve our customer’s needs for a robust low-code development platform that includes app development, automation, chatbots, and rich, detailed data analysis and visualization. We previously reported on the fundamental security and compliance capabilities offered with Microsoft Flow which was renamed Power Automate. In this blog, we’re going to discuss the integrated security and compliance capabilities across the Power Platform and provide an update on the new capabilities we’ve launched.
Foundations of governance
As the number of developers grows, governance becomes a key criterion to ensure digital transformation. As such, IT must create stronger guardrails to ensure the growing numbers of developers and the assets they create all remain compliant and secure. The Power Platform’s governance approach is multi-step with a focus on security, monitoring, administrative management, and application lifecycle management (figure 1). Check out our detailed governance and administration capabilities. The Power Platform also offers a Center of Excellence Starter Kit which organizations can use to evolve and educate employees on governance best practices. The Power Platform comes equipped with features that help reduce the complexity of governing your environment and empowers admins to unlock the greatest benefits from their Power Platform services. We’re reporting some of our newest capabilities to protect your organization’s data with tenant restrictions and blocking email exfiltration. We’re also announcing new analytics reports available for the robotic process automation (RPA) capability recently launched with Power Automate.

Cross-tenant inbound and outbound restrictions using Azure Active Directory
The Power Platform offers access to over 400 connectors to today’s most popular enterprise applications. Connectors are proxies or wrappers around an API that allows the underlying service to ‘talk’ to Power Automate, Power Apps, and Azure Logic Apps. Control and access to these connectors and the data residing in the applications is a crucial aspect of a proactive governance and security approach. To this end, we have recently enhanced the cross-tenant inbound and outbound restrictions for Power Platform connectors. The Power Platform leverages Azure Active Directory (Azure AD) for controlling user authentication and access to data for important connectors such as Microsoft first-party services. While tenant restrictions can be created with Azure AD all up, enabling organizations to control access to software as a service (SaaS) cloud applications and services based on the Azure AD tenant used for single sign-on, they cannot target specific Microsoft services such as Power Platform exclusively. Organizations can opt to isolate the tenant for Azure AD-based connectors exclusively for Power Platform, using Power Platform’s tenant isolation capability. Power Platform tenant isolation works for connectors using Azure AD-based authentication such as Office 365 Outlook or SharePoint. Power Platform’s tenant isolation can be one way or two way depending on the specific use case. Tenant admins can also choose to allow one or more specific tenants in inbound or outbound direction for connection establishment while disallowing all other tenants. Learn more about tenant restrictions and tenant isolation. For now, this capability is available through support and will soon be available for admin self-service using Power Platform admin center.
In addition to leveraging Power Platform tenant isolation’s ability to prevent data exfiltration and infiltration for Azure AD-based connectors, admins can safeguard against connectors using external identity providers such as Microsoft account, Google, and much more—creating a data loss prevention policy that classifies the connector under the Blocked group.
Email exfiltration controls
Digital transformation has opened a variety of new communications channels. However, email remains the foundational method of digital communication and Microsoft Outlook continues as one of the dominant email services for enterprises. Preventing the exfiltration of sensitive data via email is crucial to maintaining enterprise data security. To this end, we have added the ability for Power Platform admins to prevent emails sent through Power Platform to be distributed to external domains. This is done by setting Exchange mail rules based on specific SMTP headers that are inserted in emails sent through Power Automate and Power Apps using the Microsoft 365 Exchange and Outlook connector. The SMTP headers can be used to create appropriate exfiltration (unauthorized transfer of data from one device to another) rules in Microsoft Exchange for outbound emails. For more details on these headers auto-inserted through Microsoft 365 Outlook connector, see SMTP headers. With the new controls, admins can easily block the exfiltration of forwarded emails and exempt specific flows (automated workflow created with Power Automate) or apps from exfiltration blocking. To block the exfiltration of forwarded emails, admins can set up Exchange mail flow rules to monitor or block emails sent by Power Automate and or Power Apps using the Microsoft 365 Outlook connector. Figure 2 is an example SMTP header for an email sent using Power Automate with the reserved word ‘Power Automate’ in the application header type.
Figure 2: Power Platform SMTP email header with reserved word ‘Power Automate.’
The SMTP header also includes the operation ID includes the type of email, which in figure 2 is a forwarded email. Exchange admins can use these headers to set up exfiltration blocking rules in the Exchange admin center. As you can see in figure 2, the SMTP header also includes a workflow identifier as the new ‘User-Agent’ header which is equal to the app or flow ID. Admins can exempt some flows (or apps) from the exfiltration due to the business scenario or use the workflow ID as part of the user-agent header to do the same. Learn more about how Power Platform helps admins prevent email exfiltration with these sophisticated new controls.
Powerful analytics for monitoring robotic process automation processes
One of the most exciting new capabilities offered with the Power Platform is Desktop Flows (previously known as UI flows) which provide robotic process automation (RPA) available through Power Automate. Along with this powerful new feature, we have launched new analytics dashboards to ensure admins have full visibility with new RPA processes. Admins can view the overall status of automation that runs in the organization and monitor the analytics for automation that’s built with RPA automation from the Power Platform admin center. These analytics reports are accessible to users granted environment admin privilege. Admins can access the Power Platform admin center by clicking the Admin Center from the Power Automate portal settings menu. From the admin center, admins can access either Cloud flows (non-RPA automation) or Desktop flows. The Desktop flows page offers three types of reports:
- Runs: Gives you an overview of daily, weekly, and monthly desktop flows run statics.
- Usage: Usage of the different RPA processes.
- Created: Analytics for recently created RPA processes.
Figure 3 shows an example of the new Runs report available in the admin center for Desktop flows. You can get more details on these powerful new analytics capabilities from our Microsoft docs page and our announcement blog. Check them both out.
