Encrypted
Most device management platforms store your photos, location, messages, and screen data in plaintext on their servers. They can read it, hand it to third parties, or get breached. Your most sensitive information is one subpoena or hack away from exposure.
On Android, every photo, location ping, screenshot, and message is encrypted before it ever leaves the device — using a key derived from your password, in your browser. The server stores opaque ciphertext it physically cannot open. Zero-knowledge by architecture, not by policy.
Built for every platform
Android phones, Windows PCs, and Linux desktops/servers — all from a single secure console.
Full device-owner control on Android — live location, on-screen text awareness with AI analysis, photo and screenshot check-ins, calls, SMS, contacts, app control, and remote commands. All encrypted before it leaves the device.

AI malware scans, behavioral EDR and ransomware defense, default-deny application control via AppLocker, AI screen-text capture, USB lockdown, and secure encrypted remote troubleshooting — all from the same secure dashboard.
Application allow-listing, USB device lockdown, IT audit mode, and encrypted remote troubleshooting for Debian-based Linux desktops and servers — from the same secure dashboard.

Why SentinelMDM
Android data is encrypted on-device before it ever leaves. The server stores ciphertext it physically cannot read, hand over, or sell.
Data minimization enforced in code. Every encrypted log and binary object auto-purges after 30 days — no indefinite retention.
On Android, Device Owner prevents removal. On Windows and Linux, behavioral detection and application control keep protection running.
The SentinelMDM difference
On Android, your data belongs to you. It's encrypted with a key derived from your password, in your browser, before it ever leaves the device. We physically cannot read it, hand it over, or sell it. Because the key never leaves you, we also cannot reset your password — true zero-knowledge.
How zero-knowledge worksAndroid

App control + USB lockdown
Android phones, Windows PCs, and Linux desktops/servers — all from a single secure console. No second console, no extra subscription, no fragmented visibility.
See all featuresOn Android, SentinelMDM runs as Device Owner — Android's built-in trusted-administrator role. It cannot be uninstalled, force-stopped, or evaded by powering the device off. On Windows and Linux, behavioral detection and application control keep protection running.
Learn about Device OwnerCommon questions
Yes, when used as intended: an account holder supervising devices they own or are authorized to administer, with the monitoring disclosed to the device user. SentinelMDM is built for disclosed, consent-based supervision — not covert tracking. Recording-consent and privacy laws vary by jurisdiction, so lawful use is the account holder's responsibility.

On Android, no. SentinelMDM uses zero-knowledge end-to-end encryption: photos, video, screenshots, audio, location, and on-screen text are encrypted on the device before they ever leave it, with a key derived from your password inside your browser. Our servers only ever store opaque ciphertext we cannot read, hand over, or sell. Because the key never leaves you, we also cannot reset your password or recover your Android data if you lose it. Windows and Linux telemetry travels over encrypted tunnels and is stored encrypted at rest. How zero-knowledge works →
SentinelMDM installs as a Device Owner on Android. Android itself shows a standard "This device is managed by your organization" notice in Settings — that's built into the OS and happens with any Device Owner app. Beyond that default Android notification, SentinelMDM runs silently in the background with no persistent icon, banner, or user-facing indicator. If you use our SentinelOS build (a custom-hardened OS flashed onto a Pixel), that Settings notice and other Device Owner alerts are removed entirely — the device looks and feels like a normal phone.
A complete picture from one dashboard. On Android: live map and location history, geofencing alerts, platform-level on-screen text awareness, on-demand photo and screenshot check-ins, calls, SMS and contacts, installed-app control with allow/block lists, and remote controls such as lock, factory-wipe, and a max-volume locate alarm. On Windows PCs: security and remote support — AI malware scans, behavioral EDR and ransomware protection, application control via AppLocker, AI screen-text capture, USB lockdown, and secure remote troubleshooting. On Linux desktops and servers: application control, USB lockdown, IT audit mode, and encrypted remote troubleshooting.
No. On Android, SentinelMDM runs as Device Owner — Android's built-in trusted-administrator role. It cannot be uninstalled, force-stopped, or evaded by powering the device off, so protection stays on.
All captured telemetry automatically purges on a strict 30-day TTL, aligned with COPPA data-minimization. SentinelMDM starts at $3/device/month and includes a 30-day free trial. See pricing →
Yes. After creating your account, you can permanently activate Business Account mode. This ensures compliance by disabling invasive captures (like audio/video and keylogging) and lets you create team sub-users to help manage your business devices, with end-to-end encryption intact.
Yes. Alongside Android monitoring, SentinelMDM supports Windows PCs and Linux desktops/servers from the same secure dashboard — AI malware scans, malware/ransomware protection, application allow-listing via AppLocker, screen-text capture, USB lockdown, IT audit mode, and secure remote troubleshooting.

Traditional antivirus mostly matches files against a database of known threats, so it's often blind to brand-new or custom malware. SentinelMDM instead uses behavioral detection (watching how processes actually act, not just known signatures), default-deny application control that blocks anything not explicitly approved from running at all, and ransomware canary files that detect the file-encryption pattern ransomware relies on and can automatically isolate the PC from the network. No security product can guarantee protection against every threat, but this layered, behavior-first approach catches classes of attacks signature-based antivirus commonly misses.
