Appgate SDP is a free utility designed for Windows that provides secure access to enterprise and cloud-based resources. It generates a unique encrypted 'segment of one' for each user session, ensuring that access is strictly controlled based on various criteria, including device, location, and time. This dynamic approach significantly enhances security by making network resources invisible to unauthorized users, thereby reducing potential attack surfaces.

The software supports a Zero-Trust security model and is built to be scalable and resilient, accommodating mobile and desktop users across various environments, including on-premises and hybrid setups. Appgate SDP integrates seamlessly with existing business systems, allowing for the creation of dynamic access rules tailored to organizational needs. This makes it a robust solution for securing sensitive data and resources.
