Safend Protector prevents internal and external data leakage by monitoring endpoint devices and data flow. It employs granular and customizable security policies to control access to physical and wireless ports, storage media, and devices, identifying and restricting them by class, vendor, model, or serial number. The product uses a kernel-level Digital Membrane technology to enforce policies, blocking unauthorized access and allowing only permitted devices through specified interfaces. It also provides features like AV SCAN for virus detection on removable devices, transparent encryption, and comprehensive reporting. Safend Protector complies with regulations such as PCI, HIPAA, SOX, and EU GDPR, ensuring protection of sensitive data across endpoints.
