Scytale Armour Mobile

Scytale Armour Mobile provides all the functionality of consumer-grade apps, but with considerably greater security.

Most importantly it protects not only the content of communications, but also the associated meta-data. This means no-one even knows you are having a conversation, let alone what that conversation is about.

Scytale Armour Mobile provides secure voice calls, video calls, one-to-one and group messaging, conference calls, file attachments and sent/ received/read message status.

Scytale Armour Mobile prevents mobile communications whether voice, text, video or conference from being intercepted by devices such as IMSI catchers, or hacks using the SS7 protocol and others.

It enables secure collaboration between trusted colleagues when discussing commercially sensitive information such as corporate intellectual property, financial transactions, and customer details.

When being used on Samsung Mobile it can also provide an extra layer of hardware security using Samsung Knox.

Scytale Armour Desktop

Scytale Armour Desktop takes the functionality of Armour’s secure mobile communications technology and delivers it to the Enterprise via a Windows 10 softphone.

It allows users inside and outside the organisation to communicate transparently within a secure and private environment, ensuring valuable corporate assets are fully protected whilst maximising the productivity and flexibility for workers.

Organisations are able to take advantage of the reduced costs and increased flexibility provided by Voice over IP corporate communications.
