DATA DIODES

One-Way Network Security

Advenica data diodes are hardware-enforced one-way communication devices that allow data to flow securely between networks while completely blocking reverse traffic.

Unlike firewalls, they provide physical network separation, eliminating the risk of external attacks.

Key features:

  • Guaranteed one-way data transfer,
  • Protection against cyber intrusion and malware,
  • Hardware-based security (no software vulnerabilities).

Available models:

  • DD1000i – High-assurance data diode with proxy functionality,
  • DD500E – Industrial data diode designed for OT environments,
  • DD1G – Reliable core data diode solution,
  • DDSFX-10G – High-speed (10 Gbps) secure data transfer,
  • DD1000A – Maximum security one-way communication.

Data Diode Services

Advenica Data Diode Services are software applications that enable structured information exchange over data diodes.

  • Convert bidirectional protocols into unidirectional communication,
  • Enable integration with legacy and modern systems,
  • Support file transfer, logging, and system data exchange.

Secure remote access

Controlled access without compromising security

The Advenica Remote Access Device delivers secure, controlled access to sensitive systems without exposing them to cyber risks.

It enables operators to perform maintenance, troubleshooting and administration while maintaining strict separation from corporate and public networks.

Key advantages:

  • Secure remote maintenance,
  • Reduced exposure to internet-based threats,
  • Controlled administrator access,
  • Support for highly sensitive environments,
  • Improved operational resilience.

Perfect for industrial environments, utilities, and critical infrastructure operators.
