Available on both iOS and Android, Proxi provides a digital alternative to physical privacy screens, enhancing personal data security in public environments.

SiteKiosk is a kiosk lockdown software primarily designed to secure public access terminals by replacing the Windows shell and restricting user interactions. While not a dedicated privacy screen tool with features like gaze detection or dynamic screen dimming, it enhances privacy through content restriction, automatic logoff, and prevention of OS access on shared devices. It's best suited for controlled environments like kiosks where visual privacy is achieved via limited visibility rather than real-time user detection.

KioWare is a kiosk lockdown software solution designed to secure devices by restricting access to specific applications, websites, or content, ideal for public-facing deployments. As a privacy screen tool, it provides idle timeout features that can blank the screen, launch a screensaver, or lock the kiosk after inactivity to prevent shoulder surfing or unauthorized viewing. It supports remote configuration and monitoring across Android, Windows, and Linux platforms, making it suitable for enterprise kiosk management.

TeamViewer is a versatile remote access and support platform that includes a Privacy Mode feature, which blacks out the remote computer's physical screen during sessions to prevent unauthorized viewing by others nearby. This capability protects sensitive data from shoulder surfing on the remote end, making it useful for secure remote IT support and troubleshooting. While primarily designed for remote desktop control rather than standalone privacy screening, its privacy tools integrate seamlessly with cross-platform connectivity.

AnyDesk is a high-performance remote desktop software that allows users to securely access and control another computer over the internet with low latency. It features end-to-end encryption and permission controls for remote sessions, which can indirectly support privacy by limiting who can view or interact with screens remotely.

This positions it as a poor fit for traditional privacy screen software needs.

Splashtop is primarily a remote desktop and access software that includes a screen blanking feature, functioning as a privacy screen by blacking out the local display during remote sessions to prevent shoulder surfing.
