Introduction
The CYRUS Unidirectional Gateway is a next-generation data diode solution, engineered to provide absolute data security combined with exceptional high-performance transfer capabilities. Unlike traditional firewalls, CYRUS ensures that information flows in a strictly one-way direction—from isolated networks to IT networks—completely eliminating the risk of external cyber threats.
With its high throughput and protocol-level intelligence, CYRUS is designed to safeguard critical infrastructures, sensitive government environments, financial networks, and enterprise systems. Customers benefit from seamless integration, unmatched reliability, and guaranteed isolation security.
Key Features
- High Performance: Supports large-scale data transfers at speeds up to ۱۰ Gbps, ensuring files of several gigabytes are transmitted within seconds.
- Absolute One-Way Security: Hardware-enforced data flow guarantees that no reverse communication is possible, preventing operator errors or insider sabotage.
- Protocol-Level Control: Blocks any unauthorized protocol before entering the device, not after. Only approved traffic is allowed to pass, increasing system-wide resilience.
- High Availability (HA) at Data Diode Level: Using modular diodes and link aggregation, bandwidth can be increased, and in case of a diode failure, communication continues without interruption.
- Multi-Protocol Handling: Simultaneous support for Database, Syslog, and File Transfer protocols (FTP, TFTP, SFTP, FTPS, TLS, UDP, TCP) with full compatibility and conversion options.
- Future Expandability: Additional protocols can be integrated based on customer requirements and joint technical sessions.
- Flexible Deployment: HA support also exists at the appliance level, allowing critical infrastructures to scale securely.
Applications
- Critical Infrastructure Protection: Energy, utilities, and transportation sectors requiring strict data isolation.
- Government & Defense: Secure communication in classified and sensitive environments.
- Financial Institutions: Secure database replication and log transmission in banking networks.
- Industrial Enterprises: Protection of isolated OT/ICS environments while enabling secure data exchange with IT systems.
- SIEM & Monitoring Systems: Reliable one-way Syslog transfer to SIEM without exposing the source network.
Unique Advantages
- True hardware-enforced one-way communication, eliminating operator or configuration errors.
- Protocol-level security filtering, blocking all unauthorized protocols at the LAN input stage.
- High bandwidth and reliability, ensuring business continuity and uncompromised data security.
