Secure Communication for Mobile and Field Workforces
Field officers, clinical workers, site inspectors, emergency responders, and mobile sales teams carry sensitive operational information into unpredictable environments - across variable networks, on shared or personal devices, and often without IT support nearby. Sanket provides encrypted mobile-first communication designed for the security, reliability, and device trust requirements of distributed workforces operating in the field.
Offline queueing - no lost messages in poor signal
Remote revocation for lost or stolen field devices
Device trust controls for BYOD policy enforcement
End-to-end encrypted even on public Wi-Fi and 4G
The shift
Before Sanket vs. After Sanket
Before - current state risks
Mobile-first encrypted messaging built for field operations: works on 4G, Wi-Fi, and low-bandwidth connections
Offline message queueing: messages deliver securely when connectivity is restored - no lost communications
Device trust enrolment: approved devices get access; unenrolled personal devices can be blocked by policy
Remote device revocation: instantly cut access to a lost, stolen, or compromised field device
After - with Sanket
Encrypted file sharing lets field teams send photos, reports, and sensitive documents directly from the field
Push-to-group broadcasts for operational updates, safety alerts, and time-critical field instructions
End-to-end encryption protects sensitive communications even when field teams use public or untrusted networks
Built for this
The architecture that makes encrypted communication for mobile and field teams work
Mobile workforces operate in environments where device loss is a routine risk and network security cannot be assumed. Sanket's end-to-end encryption ensures that a lost or compromised device does not expose communication history, while offline queueing ensures that sensitive operational messages are never sent unencrypted over degraded networks.
Zero-Knowledge Server
The field workforce security challenge is device trust and network unpredictability. Sanket addresses both: device enrolment ensures only approved devices access company communication, remote revocation limits the damage from lost devices, and Signal Protocol encryption protects communication regardless of the network quality or security.
Signal Protocol E2E
Open-standard cryptography with Double Ratchet key derivation. Each message session generates unique ephemeral keys.
Admin Governance
Administrators control identity, groups, devices, retention, and access revocation - properties consumer apps cannot offer.
Sovereign Deployment
Sanket.Work is typically deployed as the field team communication platform with mobile-optimised apps for Android and iOS. Organisations with complex device management requirements can integrate Sanket with existing MDM solutions. For classified field operations, Sanket.Enterprise provides the same mobile capabilities in an isolated deployment.
The result
What organisations achieve
Eliminate the risk of sensitive operational information being exposed when field devices are lost, stolen, or used on untrusted networks
Provide field teams with reliable encrypted communication that works regardless of network quality - from strong 4G to intermittent rural connectivity
Enforce device trust across a distributed mobile workforce, ensuring only approved, enrolled devices can access company communication channels
Evaluation guide
Questions every buyer should ask
Does the platform support offline message queueing for field teams with intermittent connectivity?
Can administrators immediately revoke access from lost or stolen field devices?
Does device trust enrolment prevent unapproved personal devices from accessing company channels?
Is end-to-end encryption maintained even on public Wi-Fi and 4G networks?
Does the mobile app work reliably on Android and iOS devices used by field teams?
Can the platform integrate with existing MDM solutions for device management policy enforcement?
FAQ
Frequently asked questions
What happens if a field worker's device is lost or stolen?
Sanket.Work administrators can immediately revoke access for a specific device. The remote revocation is instant - the device loses all access to company communication channels. End-to-end encryption also means that message history on the device is encrypted and cannot be read without the device's private key.
How does Sanket handle intermittent mobile connectivity in the field?
Sanket queues messages securely when a device is offline and delivers them in order when connectivity is restored. Field workers do not lose incoming messages during network outages - they receive them when they reconnect.
Can Sanket work with our BYOD policy?
Yes. Sanket.Work supports device enrolment controls that can require approved device registration before access is granted. Administrators can configure policies that allow or restrict BYOD access based on the organisation's security posture.
Is Sanket secure enough for field workers on public Wi-Fi or untrusted networks?
Yes. Signal Protocol end-to-end encryption protects communication content regardless of network security. Even if an attacker intercepts the network traffic, they see only encrypted data that cannot be decrypted without the recipient's private device key.
Can field teams send photos and documents securely?
Yes. Sanket supports encrypted file and document sharing, including photos taken in the field, reports, and operational documents. Files are end-to-end encrypted like messages - accessible only to intended recipients.
