Security Strategy

Sheltor Security Strategy

Sheltor is a voice and IP messaging solution that uses the Internet to transfer data. Voice calls and messages are end-to-end encrypted at the hardware level using AES 256 along with any other standard simultaneously along with as three basic technologies for different areas of communication - symmetric encryption, asymmetric encryption, and public key distribution. This ensures that the conversation is accessible only to authorized parties during a communication session.

Sheltor servers, mobile and stationary devices are designed and manufactured using our own technology from proven components that guarantee the absence of hardware “bookmarks.” Encryption of messages and voice communications takes place inside proprietary chips and ensures complete secrecy.

supports LTE, Wi-Fi and Bluetooth LE.

Modular cryptography

Sheltor’s modular cryptography allows you to use one or more types of encryption, either individually or in combination (sequential encryption). Sheltor servers are secured against brute force and DDoS attacks and can be cloned to ensure continuous operation while being located all around the globe. The servers can be placed at any site at the client’s discretion to ensure full security. Nobody — not even the equipment supplier — will be able to access the data.

In the Sheltor ecosystem you can transfer and store media-rich data such as photos and videos using the untrusted cloud services like Amazon. In addition to unprecedented security, we are also focused on user-friendliness and have implemented both voice conferencing and convenient group chats. We have developed a simple and clear network administration system with the ability to connect friendly Sheltor networks to ensure secure communications between different companies.

Connect

Sheltor Connect

Sheltor Connect is data transfer solution with voice, messaging and multimedia support. Depend-ing on the necessary security level, Sheltor Connect solutions may include software and hardware prod-ucts. Voice and text messages are point-to-point encrypted using AES-256 hardware algorithms. Three component technologies are used for various communication scenarios: symmetric encryption, asym-metric encryption and open key distribution. Sequential real-time encryption by several algorithms significantly increases cryptographic strength.

Sheltor Connect provides secure communication both between company employees and customers. Its rich business functionality allows both communication using voice and messaging as well as document creation, transmission, and editing in a secure cloud.

Sheltor's modular cryptography allows the use of one or more encryption algorithms, either individually or sequentially. In this way, Sheltor protects data from possible vulnerabilities in the encryp-tion algorithms themselves.

Diode

Sheltor Diode

The Sheltor Diode crypto complex is designed to organize communication between local area networks and is used for protecting information while transferring data over open channels. Communication solutions are selected in the design stage based on the kind of traffic, network topology and bandwidth required for the networks, their segments and individual users.

Sheltor Gate Diode is intended for guaranteed unidirectional transfer of data from open networks to confidential networks, which may be used for classified information transfer at the state secret level. In addition, the data diode can be used to transfer information between networks to ensure the integrity and availability of the transmission network in the absence of confidentiality requirements. In the first case, unidirectional transfer of data to restricted-access networks avoids leakage of confidential information. In the second case, Diode provides protection to the transmitting network from the possibility of external influence.

Sheltor 1G/10G

The Sheltor 1G/10G high-speed gateway is intended for unidirectional transfer of data from open networks to confidential networks, suitable for classified information transfer at the state secret level. Two network segments can be connected through the information diode if integrity and/or availability must be ensured. In the first case, the guarantee of unidirectional data transmission prevents information leakage from the confidential network. In the second case, undesirable external impact on important infrastructure located in the transmitting network segment can be avoided.
