Customers Challenges

A recent FM Global Survey of 200 business leaders at Fortune 500-size organizations found 84% of them categorize a cyber-attack on industrial control systems as a “major concern” for their business. Read FM Global survey

Since over a decade ago, cybersecurity has become a significant factor in the overall risk management cycle for industrial installations, process plants, and other critical assets (i.e. sensors, motors, and other control devices). Among our customers, there is a wide understanding of the potential benefits of the IIoT (Industrial Internet of Things), Cloud, and Industry 4.0 transforming operations bringing industry innovations, better products, smarter services, and higher work efficiency. At the same time, posing cybersecurity risks for safety and business continuity has challenged customers to open a new digitalized world securely.

Customer Benefits of Cybersecurity Lifecycle Management

Yokogawa’s Cybersecurity Lifecycle Management is a comprehensive security suite of indispensable solutions for the sustainability and efficiency of your control system.

  • Security Program will align and improve the capabilities of the plant’s key elements-people, process, and technology to reduce the cybersecurity risk. It helps to overcome the great challenge of closing the gap between these three key elements.
  • Taking individual plant’s lifecycle perspective, a developed security roadmap will support companies to create a mid to long term plan on how to carry on the security program lifecycle for their plant and in which manner to implement the countermeasures in achieving the company goals so that it is easy to understand the security journey by all the stakeholders.
  • As a result, the security program brings more effective organizational team effort involving all employees. It greatly helps to strengthen employees’ higher commitment in their daily security performance as well.
  • This program is run on a global methodology, executed in the same manner, following international security standards IEC 62443, a global standard for the security of Industrial Control Systems. Hence, no matter where the customer site across the world, the global Yokogawa team can reach out and deliver the same result.

Nitrogen Fertilizer Manufacturer Cyber Security Implementation Success Story


This white paper provides an overview of how Yokogawa believes its customers can best prepare for and position themselves to benefit from IIoT-enabled technology and solutions and digitalization in general to emerge as the successful connected industrial enterprises of the future.


yi-MAC stands for YOKOGAWA Innovative Main Automation Contractor:

  • Full control of scope and schedule across packages
  • Realization of customer expectation
  • Single point of responsibility
  • Providing fully integrated solutions

The ability to deliver a full scope of project execution capabilities is becoming more important than ever for automation suppliers that wish to compete on a global scale. Process automation suppliers have always had some degree of project execution capabilities, but only recently have suppliers and end users begun to realize the true economic impact that precise and comprehensive execution capabilities can have on the success of an automation project and on plant lifecycle costs.

White Paper

The number of incidents involving attempted unauthorised access to computer systems via the internet as reported by CERT (Computer Emergency Response Team) was 137,539 in 2003. Statistics show an exponential increase in the number of reported incidents in the last five years. Although this can be partly explained by the increase in the number of computer systems in the world that are connected to the internet, it is nevertheless an alarming fact.


Yokogawa’s industrial automation (IA) product and service offerings, industry domain knowledge, and VigilantPlant approach – which emphasizes safe, secure, and uninterrupted operations -- provide a solid foundation for an Industrial Internet of Things that specifically addresses the requirements of process automation, particularly for the OT side of the equation. To be able to provide an equally solid foundation for the IT side, Yokogawa is partnering with Cisco Systems and other industry leaders.


Network and system security is now a necessity in process automation industry. YOKOGAWA provides a service lifecycle solution for cyber security to ensure that the security measures and deployments are continuously enhanced, monitored and inspected.

This white paper explains the details of the security design, implementation, operation and validation solutions from the technical perspective.


Initially when control and safety systems moved away from being hardwired and relay-based to computerized systems, vendors and asset owners were more interested in functionality than security. Typically, especially in high risk environments in refineries and off-shore oil installations, the systems were standalone with a dedicated Safety Instrumented System.


Over the last ten years more security solutions have available, and more industrial end users have implemented them to protect their businesses. Today nearly all companies use an anti-virus product installed on their industrial control system (ICS), as well as having their ICS segregated from the business network and the Internet by a firewall.

    ICS Cybersecurity Solutions for Unsupported Operating Systems

    A unique challenge facing operators of industrial networks is the limited ability to update the operating systems (OS) in servers and workstations.  In many cases, the OS can be upgraded only during a plant shutdown. In today’s industry, plant wide shutdowns for a variety of maintenance activities and upgrade projects might not take place any more often than every 5-10 years.
