Asset Discovery

SNOK gives visibility of endpoints in the network and their communication patterns.

Real Time Monitoring

SNOK monitors industrial networks and endpoints in real time for all types of cyber attacks.

Enterprise Solutions

SNOK scales hierarchically for large, complex multi-site industrial infrastructures.

Critical Infrastructure

Hacking, malware and viruses have attacked IT systems for decades. Recently, cyberattacks has grown into a serious threat to critical industrial infrastructure as well. What has happened and how can infrastructure be protected?

Oil & Gas

Assets in the Oil & Gas Industry are attractive targets for cyber-attacks with potentially severe consequences. Combined with strong digitalization and automation trends the cyber risk is rapidly increasing. Read about what regulators and the industry itself is doing to reduce its risk exposure.

Electric Power

Today, society reliable operation of the power grid is critical for our society. The tolerance for major outages is low. At the same time, operation of the grid relies heavily on automated control systems that are vulnerable to cyber attacks.


Traditionally, security risks to Water Management Systems have been mitigated through maintaining an “air-gap” from other computer systems. Today technical similarity and interconnectivity with IT systems are increasing and so is the exposure to the global cyber threat landscape.


Railway signaling, flight control, traffic light control and other transportation management systems depends on automated systems. Some of these systems may be vital to a nation’s security. For all, safe and reliable operation is essential.


Modern manufacturing rely on inter-connected power-driven machinery. With the transition to Industry 4.0’s massive interconnectivity, questions arise of how to prevent cyberattacks to avoid manufacturing downtime, damage to equipment as well as safety risks to personnel.

Process industry

PLCs are the automation workhorses of  processing plants. These rugged, reliable devices control often critical processes. Traditionally, PLCs are not designed with security in mind. A cyber attack or tampering with PLCs can cause downtime or even destruction and accidents.


Ships are becoming increasingly connected and reliant on software intensive systems. Combined with continued use of legacy systems not designed to be secure and generally low cybersecurity awareness among seafarers, maritime vessels are vulnerable to cyber attacks.
We in Secure-NOK™ have designed our solutions bottom-up for industrial purposes. SNOK™ Cybersecurity Monitoring System can be deployed to all types of facilities from large plants to remote, unmanned stations. It provides you with automatic early warning of malware/virus, unauthorized changes and all stages of hacking attempts on your system.
