Prevent your SCADA from being hacked

To make things easier to control, the use of digital data becoming an integral part of business and increasingly integrated into all interconnected systems. High profile industries often fall prey to cyber attacks by damage caused by a hacker or computer virus aimed to erase data or malfunction equipments or infrastructure. In order to protect your assets and operation from cyber threats, organisation needs to rethink traditional solutions and place next generation cyber-security technology to defend industrial control systems.

Major threats for ICS 

  • Stolen intellectual property of gas field exploration chart.

  • Disruptive attacks on SCADA and ICS that sit out side of traditional security walls.

  • Hacker gaining full control of SCADA system to control energy, oil & gas, chemical and transportation sector.

  • Issues with traditional solutions: Air-gap introduce delay, any (software) firewall can be hacked, data leakage and infection of malware and viruses.  


  • Simplex Systems eliminates dangerous remote code execution holes.

  • 100 % data assurance. 

  • Transfer real time data one way

  • Hardware based solution eliminating all software base vulnerability.


Simplex System data diode one way characteristic allows you to monitor your operational technology but ensure that all cyber attacks are unsuccessful. Unlike software solutions, it is a hardware based ​solution that cannot be hacked. 

  • Based on a light emitter and a light receiver: two-way data transfer in front, one-way data transfer behind

  • The Simplex system data diode is placed between your key critical infrastructure (e.g. BOP, drilling equipment, thrusters, etc.) and your IT / corporate (office) network for monitoring.

  • Complete replication from source schema

  • High availability and historical backfill capabilities

  • Support multiple protocol - Modbus, OPC UA, DNP3 and many more ICS protocol.

System Setup

The recommended set-up includes the Simplex Systems hardware unit and a proxy server on each side of the unit in order to convert bi-directional protocols into a one-way protocol (on the upstream side) and vice versa (on the downstream side). These proxy servers are equipped with turnkey software solutions to hook into environments and provide secure one-way data transfer from production networks to a corporate environment.

The DataDiode solution consists of the following elements:

  • 2 historians - 1 historian to collect the original data and 1 replicator historian that can be accessed remotely

  • 2 proxy servers - On both ends of the DataDiode hardware

  • DataDiode hardware - The core  hardware-based security solution


Data Assurance

Simplex is the solution of choice for organisations across Malaysia, due to its ease of use, flexibility and impressive feature range.
