Comparison Table
Frosted
SMBScreen sharing privacy tool that creates a 60fps mirror of your display with selected apps masked at the pixel level.
Active-window reveal keeps the selected Mac window usable while Frosted obscures surrounding desktop content.
Frosted focuses on macOS desktop privacy rather than browser-only masking. The app applies an adjustable frosted overlay that obscures inactive windows while preserving access to the selected window. A quick toggle supports short privacy events such as screen sharing, coworking, and in-person presentations.
The active-window approach reduces visual clutter, but it depends on the correct window remaining selected. Frosted is best suited to individual Mac users who need rapid desktop masking, not organizations requiring centralized policies, endpoint administration, or audit logs.
- +Active-window reveal keeps the current task readable
- +Menu bar access enables quick privacy activation
- +Keyboard shortcut supports rapid desktop masking
- +Works without modifying files or application content
- –macOS focus limits compatibility with Windows teams

Cloaky
SMBmacOS app that places resizable blur or solid overlays on any part of the screen for privacy during demos, recordings, and screen sharing.
Endpoint agent automation that turns masking on when sensitive content is detected, with manual toggle overrides for edge cases.
Cloaky runs as an endpoint privacy screen agent that enforces visual obfuscation without requiring users to remember hotkeys for every context. Automation is driven by trigger logic that activates masking when sensitive UI is present, and users can still use a manual toggle for quick control. The tool supports multi-monitor setups so masking can remain consistent across common workspace layouts.
A tradeoff is that reliable masking depends on accurate trigger detection for the specific applications users run. Cloaky fits best when organizations need standardized privacy screen behavior for knowledge work and customer support roles that frequently switch between video calls and sensitive systems.
- +Automated privacy detection reduces reliance on user hotkey discipline
- +Manual privacy toggle supports quick override during meetings
- +Multi-monitor masking keeps obfuscation consistent across displays
- +Centralized policy rollout standardizes behavior across endpoints

How to Choose the Right Privacy Screen Software
Privacy screen software options differ mainly in how reliably and controllably they enforce privacy on-screen. Focus on criteria like Screen lock behavior and Update frequency so you know what happens during real demos, not just on paper.
Screen lock behavior on focus loss
Why it matters
Screen lock behavior on focus loss matters because privacy tools fail at the moment you switch apps or screens. If the lock timing is off, you get brief oversharing windows even in normal use.
How to check
Start a privacy session, then switch between apps and back quickly while watching what appears. Ask whether there’s a configurable delay and whether the screen returns instantly on focus regain.
Mask coverage for dialogs and popups
Why it matters
Mask coverage for dialogs and popups matters because sensitive content often appears in overlays you didn’t plan for. If popups, password prompts, or permission dialogs bypass the mask, privacy breaks.
How to check
During the demo, open common UI elements like a browser print preview, a login prompt, and a document viewer popup. Confirm the protected area stays masked and does not re-expose content when the dialog loads.
Protection scope for screenshots and recording
Why it matters
Protection scope for screenshots and recording matters because many privacy leaks happen after the fact. If capture controls are partial, users may still export or record what should be hidden.
How to check
Try to capture via the OS screenshot function and start a screen recording in a controlled demo. Check whether the tool blocks capture, blurs content, or produces a blank/gray output, and whether behavior matches its documentation.
User controls for privacy on demand
Why it matters
User controls for privacy on demand matter because teams need predictable behavior during calls, walkthroughs, and quick check-ins. Controls that are confusing or unreliable lead to accidental exposure.
How to check
Ask for the exact workflow to enable and disable protection during a live session. Test that the control works consistently across app switches and that state is obvious (for example, a clear indicator).
Update frequency for OS and app changes
Why it matters
Update frequency matters because privacy behavior often depends on how apps render content. When browsers or OS components change, outdated tools can stop masking correctly.
How to check
Review the product’s changelog history and look for updates tied to recent OS or major app changes. Ask what their maintenance cadence is for fixes when a masking regression is reported.
Audit log and admin visibility
Why it matters
Audit log and admin visibility matter when you need proof that privacy was applied in practice. Without logs, it’s hard to answer “Was protection active during this session?”
How to check
In a demo or admin view, look for event history that records enable/disable actions and any failures. Ask whether logs can be exported and retained and whether roles limit who can change settings.
Red flags
- Masking briefly fails when switching apps or windows
- Capture protection is only partial or unclear in real tests
- No recent updates for OS or major app rendering changes
Fit by situation
- If people frequently switch between apps during calls, prioritize Screen lock behavior on focus loss.
- If your work involves popups like logins and print previews, prioritize Mask coverage for dialogs and popups.
- If you need proof of protection during reviews, prioritize Audit log and admin visibility.
