What is Ostiarius FOR MAC?

Ostiarius FOR MAC

The Gatekeeper security feature introduced by OS X Mountain Lion helps you prevent unsigned applications from being launched, thus keeping malware at bay. It can, however, be bypassed, so a third-party tool may be required to ensure potentially harmful content is not installed.

Extra Layer of Security

• Verifies quarantine attributes


• Blocks unsigned binaries


• Utilizes kernel extension

The downloadable installer copies and starts a signed kernel extension that is launched automatically upon reboot and monitors activity in the background.

Automated Protection

• Runs at kernel level


• Protects all users


• No manual launch needed

Any unsigned application downloaded from the Internet is blocked by Ostiarius, without displaying any notifications, although these actions are logged and can be analyzed from the Console app.

Easy Installation

• Simple to install


• No additional configuration

Ostiarius provides a reliable alternative to macOS' Gatekeeper, as it blocks all unsigned applications from being executed, even those that may be missed by the native macOS security feature.
