Lock Any Device.
From Anywhere. In Seconds.

Clicks for the Attacker

One click. Four steps. Locked.

STEP 01

Issue the Command

Click Lock in your Sentinel dashboard. No confirmation dialogs. No IT tickets. The command is signed, queued, and dispatched in under 500ms.

STEP 02

Server Queues Instantly

The command waits securely in the server queue, encrypted with the device's unique JWT token. If the device is offline, the command is held until it reconnects.

STEP 03

Device Executes

On the next poll cycle — typically within 15 seconds — the device fetches, verifies, and executes the lock command. The screen locks immediately.

STEP 04

Confirmation Logged

The dashboard confirms execution with a timestamp. All commands are logged with IP, operator identity, and device acknowledgement for audit purposes.

Why Enterprises Rely on Remote Lock

Lost Laptop on Transit

Executive leaves laptop in a taxi at Jomo Kenyatta Airport. By the time they land, the device is locked and the thief sees nothing but a custom security message.

Enterprise

Employee Termination

HR notifies IT of a termination at 9am. By 9:01am, the employee's work device is locked before they reach the car park. Access revoked instantly, no negotiation.

HR & Compliance

Stolen Phone with CRM Data

A sales team's Android with a full customer database is snatched. Lock it within minutes. Your CRM data stays yours. Customer list doesn't end up for sale.

Data Protection

Unattended Field Device

A data collection tablet left at a remote survey site. Lock it remotely after hours. Unlock in the morning for the field team. No keys, no physical retrieval needed.

Field Operations

Built to Deliver Under Every Condition

Delivery Model
Secure poll (device pulls from server). The server never holds an open connection. Every poll is authenticated with a signed JWT.
Offline Queuing
If the device is offline, the lock command is held in the queue indefinitely. The moment the device connects to any network, the command executes.
Authentication
Each device has a unique HS256 JWT token with version control. Revoking a token invalidates all prior device commands.
Custom Lock Message
Include a custom message on the lock screen — IT contact number, recovery instructions, or a warning. Configurable per command.
Platform Support
Android phones and tablets, Windows laptops and workstations, Linux servers and desktops, macOS (beta).
Unlock
Issue the Unlock command from the same dashboard. The device unlocks on next poll — no physical access required to recover a falsely locked device.
