Rolloos Cyber Security DataDiode

Prevent your rig from being hacked

As the importance of digital information grows and the world becomes increasingly dependent on interconnected systems. The damages that are caused by a computer virus or a hacker grow exponentially. You don’t want your drilling equipment to be hacked. In order to protect your assets and operation against cyber-crime, cyber security needs to have the highest priority.


  • Drilling equipment that is hacked might end up in an uncontrolled situation
  • 81% of large companies have been under attack, causing exponentially increasing consequential costs
  • Common solutions are vulnerable: air gaps introduce delays, data leakage and spreading of viruses and malware, any (software) firewall can be hacked



  • Maximum protection - Against viruses, hacking activity and espionage
  • Hardware based solution - Eliminates all external software vulnerabilities
  • Real-time monitoring - Of your systems while being fully secured
  • Supports most protocols - Modbus, OPC UA, DNP3 and more
Rolloos DataDiode Hardware


The DataDiode one-way data connection protects the integrity and availability of critical assets in Industrial Control System (ICS) networks. Due to its one-way character it allows you to monitor your (drilling) operation and BOP, but ensures that all cyber-attacks are unsuccessful. Other than a Firewall, the DataDiode is a purely hardware 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 DataDiode is placed between your key critical systems (e.g. BOP, drilling equipment, thrusters, etc.) and your corporate (office) network
  • Easy to implement: all major data protocols and transfer modes can be handled (Modbus, OPC UA, DNP3 and more)
Rolloos DataDiode Highest Certified


The recommended set-up includes the DataDiode 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
