About

Sentry Shield

Read full description

Sentry Shield is an enterprise-grade device management application designed for organizations that demand uncompromising security and control over their iOS fleet. Built for IT administrators, security teams, and B2B operators, Sentry Shield transforms standard iPhones into hardened, policy-enforced devices through a unique combination of physical NFC security cards and centralized management. KEY CAPABILITIES - NFC Security Card Binding Pair each device to a physical SENTRY security card. Only an authorized cardholder can bind, unbind, or unlock the device โ€” a tangible second factor that complements digital credentials. - Hardware Button Lockdown Disable the volume buttons, power button, and silent switch when Security Mode is active. Ideal for kiosk deployments, point-of-sale terminals, examination devices, and field operations where tampering must be prevented. - Multi-Code Unlock System Configure multiple four-digit codes with role-based scoping. Set distinct codes for device unlock, administrator override, and emergency exit. - MDM-Native Deployment Designed from the ground up for Jamf, Microsoft Intune, Mosyle, Kandji, and other MDM platforms. Deploy via VPP, push managed configurations, and integrate with your existing endpoint management workflows. - Tenant-Aware Backend The Sentry Shield client speaks fluently with multi-tenant SENTRY UEM backends. Devices automatically route to the correct tenant API based on configuration โ€” no manual server selection required. - Demo Mode for Trials and Reviews Toggle Demo Mode to evaluate the full user experience without requiring physical NFC cards or backend connectivity. Perfect for procurement evaluations and onboarding sessions. PRIVACY AND COMPLIANCE Sentry Shield transmits only the minimum data required for operation: device identifier, hashed NFC tag UID, and tenant credentials. All traffic uses TLS 1.2+. No third-party analytics or advertising SDKs are embedded. For organizations evaluating Sentry Shield for fleet deployment, contact your customer representative for technical onboarding, Jamf integration documentation, and pilot program enrollment. Requires iOS 18.5 or later. iPhone with NFC tag reading support required for production use; Demo Mode runs on any supported device.
