×With miniOrange CASB, you can stop data exfiltration at the source by blocking Copy, Paste, Print, Download, and even Screenshots inside Office apps and cloud storage. Protect confidential business documents, prevent insider threats, and stay compliant, all without disrupting productivity.
Protecting sensitive business data in Microsoft 365 apps, OneDrive, and SharePoint requires more than native controls. With miniOrange CASB (Cloud Access Security Broker), enterprises can block risky actions like copy, paste, print, download, and even mobile screenshots. This ensures zero-trust security, compliance (GDPR, HIPAA, SOC 2), and end-to-end data protection across all Microsoft 365 environments.
Enterprises rely on Microsoft 365 apps like Word, Excel, PowerPoint, Outlook, Teams, OneDrive, and SharePoint to store and share their most sensitive data. However, without proper controls in place, users can easily copy, paste, print, download, or capture screenshots of business-critical content, creating major compliance and insider risk challenges.
Implementing a Cloud Access Security Broker (CASB) gives organizations the visibility and enforcement they need to prevent data exfiltration and ensure compliance. Below are the key risks every enterprise must address.
Without restrictions, employees can copy sensitive information from Microsoft Word, Excel, or Teams chats and paste it into unmanaged apps like WhatsApp, Gmail, or personal Google Docs. This creates a shadow IT environment where confidential data bypasses enterprise security policies. A CASB allows admins to block copy-paste actions across Microsoft 365 apps and enforce context-based data sharing policies.
One of the most common risks is when users download OneDrive or SharePoint files onto personal laptops, USB drives, or mobile devices. Once outside managed environments, IT loses control, making data leakage, ransomware attacks, and intellectual property theft much more likely. CASB solutions enable device-based restrictions that prevent file downloads on unmanaged or unencrypted endpoints.
Printing may seem harmless, but it's a frequent source of data leakage. Employees can print contracts, financial reports, or patient records, which then exist as unmonitored paper copies. CASB lets organizations disable printing of sensitive Microsoft 365 files or enforce dynamic watermarking to track unauthorized distribution.
Even if downloads and printing are blocked, users can still capture screenshots of Teams meetings, Outlook emails, or Excel dashboards. These images can be easily shared over unsecured channels, creating blind spots for data leakage.
While CASB secures file access, sharing, and user actions in Microsoft 365, screenshot protection requires deeper control at the device level. This is where our MDM solution complements CASB, extending screenshot protection on managed mobile and desktop devices. By combining CASB with MDM, organizations can enforce end-to-end data protection, securing sensitive conversations, reports, and dashboards across Microsoft Teams, Outlook, OneDrive, and SharePoint.
Leaving these actions unrestricted exposes organizations to serious risks, including:
Microsoft 365 provides a strong baseline security, but native controls often fall short in preventing insider threats and accidental data leaks. Here's where the gaps lie:
The "View Only" permission in OneDrive and SharePoint still allows users to take screenshots, copy content with third-party tools, or print files using workarounds. This creates loopholes for data exfiltration even when download and edit options are restricted.
Conditional Access policies control who can log in and from where, but they lack granular, content-level enforcement. For example, you can't block copy/paste actions in Word Online or Excel Online, leaving sensitive data exposed once access is granted.
Microsoft 365 auditing tools log activities like sharing or downloading, but they don't generate real-time alerts for copy, paste, or print attempts. Security teams often detect data leakage only after the incident, not while it's happening.
Native Microsoft 365 policies cannot differentiate between managed and unmanaged devices at the action level. A user accessing Teams or Outlook on a personal laptop or phone can still copy or transfer files, bypassing enterprise data security rules.
miniOrange Cloud Access Security Broker (CASB) extends Microsoft 365's native protections with granular, real-time data security controls. Unlike Microsoft's default policies, miniOrange enforces content-level restrictions, preventing insider threats and accidental data leakage across OneDrive, SharePoint, Teams, Outlook, and Office apps.
miniOrange CASB disables copy and paste actions in Word, Excel, PowerPoint, and Outlook Online, ensuring sensitive data cannot be copied into unauthorized apps, documents, or devices. This prevents data leaks even if users have "view only" permissions.
Organizations can block or restrict printing of confidential files directly within Microsoft 365 apps. miniOrange CASB ensures that sensitive reports, financial records, and customer data stay protected from unauthorized access.
miniOrange CASB enforces strict download restrictions, allowing admins to block downloads entirely or permit them only on managed devices.
Screenshot protection is handled by our Mobile Device Management (MDM) solution, which blocks screen captures across Microsoft Teams, Outlook, and Office mobile apps. By pairing MDM with CASB, enterprises can cover both data exfiltration risks (copy, paste, print, download via CASB) and visual leaks (screenshots via MDM), ensuring complete Microsoft 365 data security.
With miniOrange CASB, policies adapt dynamically based on user role, device type, IP range, and geolocation. For example, a user accessing OneDrive from a corporate laptop may be allowed to download, while the same user on a personal device is restricted.
miniOrange CASB delivers real-time monitoring and alerts for risky actions like copy, paste, print, or suspicious login attempts. Advanced UEBA (User and Entity Behavior Analytics) detects anomalies such as unusual file access or data transfer patterns, giving security teams immediate visibility and control.
miniOrange CASB stops sensitive data from being copied, pasted, printed, downloaded, or screenshotted across Microsoft 365 apps. By monitoring and controlling user actions in Teams, Outlook, OneDrive, SharePoint, and Office apps, it prevents both accidental leaks and malicious insider threats.
Regulatory compliance is critical for enterprises handling personal, financial, or healthcare data. miniOrange CASB enforces security policies that align with GDPR, HIPAA, and PCI DSS requirements, ensuring that sensitive files remain encrypted and access is fully auditable.
While Microsoft DLP provides basic protection, miniOrange CASB adds advanced, policy-driven enforcement. Organizations can set rules based on file type, sensitivity, user role, device, or IP, ensuring only the right people access the right data under the right conditions.
Data protection must cover every endpoint. miniOrange CASB extends consistent security to Microsoft 365 desktop apps, mobile devices, and web access. Whether users are working from corporate networks or personal devices, data remains protected everywhere.
IT admins and security teams gain complete visibility into user activity with a single, intuitive dashboard. Real-time monitoring, alerts, and detailed reports help identify risks early, accelerate incident response, and simplify compliance audits.
Imagine your company is drafting a confidential financial strategy document in Microsoft Word stored on OneDrive and SharePoint Online. Multiple employees, contractors, and third-party consultants are collaborating.
This leaves your business at risk of data leaks, insider threats, and compliance violations in Microsoft 365.
By combining CASB + MDM, miniOrange ensures your sensitive data in Microsoft 365 stays protected — across desktop, mobile, and web apps, without affecting collaboration.
Mobile devices are often the weakest link in securing Microsoft 365 apps like Word, Excel, Outlook, and OneDrive. Even if copy, paste, download, or print are blocked through CASB, a simple screenshot on a smartphone can still leak sensitive business data. This is where the Mobile Device Management (MDM) layer becomes critical, providing screenshot protection and device compliance for Microsoft 365 security.
With Mobile Device Management (MDM) policies, organizations can disable screenshots and screen recordings on managed Android and iOS devices. This ensures employees cannot capture sensitive content from Microsoft 365 apps such as Outlook emails, Teams chats, Word, or OneDrive files. Blocking screenshots at the device level provides security beyond CASB controls, preventing both accidental and intentional data leakage.
Organizations can enforce device compliance checks through enterprise mobility management before granting access to Microsoft 365 apps. Devices must meet security standards such as updated OS versions, encryption enabled, and secure passcodes before connecting. This ensures sensitive data stored in SharePoint, OneDrive, or Teams remains protected across mobile endpoints, while supporting regulatory frameworks like GDPR, HIPAA, and SOC 2.
When combined, CASB and MDM create a zero-trust security framework for Microsoft 365. CASB secures cloud data by controlling copy, paste, download, and print actions, while MDM addresses mobile screenshot and compliance threats. This dual approach ensures sensitive business data cannot escape through unmanaged devices, shadow IT apps, or weak mobile security, delivering end-to-end Microsoft 365 protection.
Protecting sensitive business data in Microsoft 365 apps, OneDrive, SharePoint, Teams, and Outlook goes beyond native controls, which cannot fully block risky actions like copy, paste, print, or download. With miniOrange CASB, enterprises can enforce granular, real-time policies that restrict copy/paste of confidential data, prevent unauthorized downloads, block printing of sensitive documents, and apply access rules based on user role, location, or device posture. CASB also provides deep visibility and compliance enforcement for frameworks like GDPR, HIPAA, SOC 2, and PCI DSS, making it the central layer of cloud security. For scenarios like mobile screenshot blocking, CASB seamlessly integrates with miniOrange MDM to extend protection to device level, ensuring complete Microsoft 365 security without disrupting productivity.
