Secure communications for voice and data

NOX is an encrypted communications application for voice, messages, files and groups. It is built for units and organisations that need to control who talks to whom, not just “a private chat”.

Why NOX

Security is the product, not an add-on

Consumer apps were not designed for institutional control. In NOX nobody invites themselves: access is granted by the organisation and the directory lives separate from the phone’s address book.

  • Users onboarded by an admin
  • Contacts outside the phone

NOX Studio

Who gets in and who gets out is decided by command

Onboarding, offboarding, groups and privileges from a single console. If a phone is lost or stolen, the account is closed or revoked in minutes. That is governance, not just “a padlock on the chat”.

  • Revocation in minutes
  • Privileges by group or role

Designed for those who operate

Less noise. More control.

Fewer in-person meetings held only to avoid “talking over WhatsApp”. It uses the phone they already have, without requiring a dedicated radio for every message.

The problem

Why use secure communications?

Encryption is not enough if the directory stays mixed in with WhatsApp. Control begins long before the message.

01

Most sensitive conversations already happen on the phone.

02

Consumer apps were not designed for institutional control.

03

A lost device or a leaked group compromises the mission.

04

Verifiable identity and the ability to revoke an account are needed.

05

A record of who administers is required, not just of who chats.

06

Encryption is not enough if the directory stays mixed in with WhatsApp.

Capabilities

NOX capabilities for secure communications

Secure contacts

The NOX directory lives inside the app, separate from the phone’s address book. When the session ends, the contacts do not stay on the device. The administrator creates and removes users from NOX Studio.

Secure voice calls

Voice is encrypted at the source and decrypted only at the destination. During the call you can switch to conference, mute the microphone, use the speaker or move to Bluetooth.

Secure messages

Content is encrypted before it is sent and the sender defines when it is deleted at both ends. Forwarding, screenshots and taking the file out of the app can be restricted.

Files and lost devices

A NOX session does not leave the history mixed in with Photos or WhatsApp. If the phone is lost, the account is revoked from Studio and the session material must not remain usable on the device.

Deployment

Multiplatform solution

Deployment target: the systems the organisation already uses. Commercial phones, no dedicated hardware.

  • iPhone
  • Android
  • iPad
  • Windows

Administration console

NOX Studio

Studio has authority over the user, not the other way round. From the console you decide who gets in, who gets out and what may leave the app.

Impact

Designed for those who operate

Faster

Fewer in-person meetings held only to avoid “talking over WhatsApp”.

Cheaper

It uses the phone they already have. No dedicated radio for every message.

More order

Who gets in, who gets out and what can leave the app is decided by command.

Use cases

The same weak point, wherever coordination happens

The sector changes, the gap does not: the conversation that connects everything ends up in an app nobody authorised.

Defence and field

Point-to-point encrypted voice on the phone they already carry, no dedicated radio.
