Blacklisting apps or app whitelisting on Android and iOS devices is crucial for enterprises to ensure that the productive employee time is not wasted on non-work apps. As digital transformation is embraced by enterprises, employees often have access to various apps, including entertainment and gaming, available through platforms like the Google Play Store and the Apple App Store.
Furthermore, having access to untrusted apps can result in malware installation on devices, causing a serious threat to critical corporate data. For preventing access to unauthorized apps on enterprise devices, a mobile device management (MDM) tool can come to the rescue.
With Scalefusion MDM, IT administrators can create comprehensive device policies that define which apps are to be allowed and which are to be blocked. By defining the policies for enterprise devices, IT administrators can whitelist apps on Android as well as iOS devices with ease.
While kiosk software can support app whitelisting or blacklisting on Android and iOS devices, Scalefusion helps achieve extensive remote management with added kiosk management capabilities.
In this article, we will be discussing how to whitelist or blacklist apps on Android and iOS devices managed MDM.
What is app whitelisting?
App whitelisting or allowlisting is a security technique that allows only a pre-approved list of software apps, libraries, or scripts to execute on a network or device. If a user attempts to install or launch an app that is not on the whitelist, it is blocked.
App whitelisting acts as a deny-by-default policy, ensuring only trusted apps run. It enhances security, boosts productivity, prevents unauthorized software installation, and eliminates bloatware.
Commonly used for kiosk mode or in corporate environments, app whitelisting is often used in combination with other security policies to fully lock down a device. This ensures that no unauthorized apps, including malware or distracting apps, can be utilized.
What is app blacklisting?
App blacklisting is a cybersecurity practice that prohibits specific unauthorized software or executable files from running on a network or computer. It acts as a deny list, blocking known malicious or unwanted programs while allowing all other apps by default.
App blacklisting is a security filter that checks launched apps against a database of prohibited items in real-time. It helps with security, productivity, and maintaining organizational security and policy compliance.
Methods of app whitelisting
1. File path-based whitelisting
When you whitelist apps using file path, they are allowed to run only if they exist in a specific directory or file path.
Drawbacks:
- Easy to bypass by copying malware into an approved folder.
- Fails if the app is updated and installed in a different location.
- Not practical for dynamic mobile environments like Android and iOS.
- No centralized visibility or control.
2. File name-based whitelisting
This method allows apps to run based on their file name (e.g., app.apk or app.exe).
Drawbacks:
- Extremely easy to bypass by renaming malicious files.
- No validation of file integrity.
- Cannot detect tampered or repackaged apps.
- Ineffective against modern mobile threats.
3. File size-based whitelisting
Apps are approved only when their file size matches a predefined specification.
Drawbacks:
- Minor updates change file size and break policies.
- Malware can mimic file size to evade detection.
- No verification of authenticity.
- Not scalable for enterprise app ecosystems.
4. Cryptographic hash/digital signature-based whitelisting
Apps are approved only if their cryptographic hash or publisher signature matches a trusted value.
Drawbacks:
- Every app update changes the hash, requiring manual reconfiguration.
- Operationally heavy for large fleets.
- Does not simplify deployment or policy management.
- Lacks device-level enforcement on mobile without a management framework.
5. MDM-based app whitelisting (recommended approach)
Apps are whitelisted through centralized policies enforced via an MDM platform like Scalefusion. Administrators define approved apps once and push policies remotely across Android and iOS devices such as Samsung and Apple.

Why MDM whitelisting is a strategic choice
Unlike static methods (file path, name, size, or hash), MDM-driven whitelisting operates at the device control layer, not the file level.
- Eliminates manual effort: No need to track hashes or reconfigure policies after every app update.
- Enforces real-time control: Instantly block unauthorized apps across your entire Android or iOS fleet.
- Scales effortlessly: Apply consistent app policies to thousands of devices in minutes.
- Reduces security risk: Prevents sideloading, shadow IT, and unauthorized installations.
- Enables compliance & audit readiness: Maintain centralized visibility and reporting.
For enterprises managing corporate-owned, kiosk, or BYOD devices, MDM-based whitelisting is convenient, operationally efficient, risk-reducing, and future-proof. If the goal is secure, scalable app control across Android and iOS, MDM is non-negotiable

How to whitelist Apps on Android devices
1. Get started by enrolling your Android devices in Scalefusion. Navigate to the Device Management section of the Scalefusion dashboard. Choose the device profile to start whitelisting apps. Set Scalefusion as a launcher.
2. Set Scalefusion as a launcher. In the Select Apps section of the Device Profile, select apps that are to be whitelisted on the select device profiles. The apps that are not selected are automatically blacklisted.
3. Alternatively, you can block apps on Android devices by blacklisting the apps in the Edit Device Profile section.
4. You can also search for apps and whitelist them.
How to whitelist apps on iOS devices
1. Navigate to the Device Profiles & Policies section of the Scalefusion dashboard. Select the iOS device profile to whitelist or blacklist apps.
2. In the Select apps section, choose the apps that you want to whitelist. App whitelisting is only available on supervised iOS devices.
3. Alternatively, you can block apps on iOS devices by blacklisting the apps in the Edit Device Profile section.
4. You can look up available apps to blacklist or whitelist apps.
Simplify app allowlisting & blocklisting with Scalefusion
Scalefusion offers comprehensive app management for Android and iOS devices, giving IT teams a centralized and consistent way to control what runs across their device fleet. App whitelisting can help significantly in ensuring that your employees are not distracted, the enterprise devices are not misused, and the data costs are always under a check. By allowing only approved applications and blocking unnecessary or risky ones, organizations can create a more secure, focused, and policy-driven digital environment. This not only improves productivity but also strengthens overall device security and simplifies ongoing device management at scale.
FAQs
1. How do I whitelist an app?
You can whitelist an app by adding it to the device’s allowed apps list in your management settings. In business environments, this is typically done through an MDM to enforce policy across devices.
2. How do I add an app to my whitelist?
Select the app and include it in your approved or allowed apps policy. With MDM, you can push this configuration remotely to multiple devices at once.
3. What is whitelist mode?
Whitelist mode allows only pre-approved apps to run on a device. It is commonly enabled via MDM for kiosk, corporate-owned, or dedicated-use devices.
4. How do I allow apps from unknown sources?
Organizations usually deploy apps from approved sources only to avoid security risks. In managed deployments, MDM lets administrators securely control and restrict unauthorized app installation.
