Tenable chosen by Wärtsilä to solve Challenges

Tenable, the Exposure Management company, has confirmed that Wärtsilä has selected Tenable OT Security to manage its operational technology (OT) asset inventory collection and provide holistic visibility into its OT environment. The deployment allows Wärtsilä to answer its customers’ questions around asset delivery, reducing supply chain risks and taking a proactive stance on cybersecurity. Wärtsilä will extend the Tenable solution to its customers, allowing them to visualize their own OT environments.

Previously, this information was collected manually with the data being reported using spreadsheets. This process was time consuming and susceptible to errors and the data could have inconsistencies both in the way it was collected and reported.

With Tenable OT Security, an industrial security solution for the modern industrial enterprise, Wärtsilä can identify assets, com- municate risk and prioritize action all while enabling its IT, security and OT teams to work better together.

The detail provided by Tenable OT Security — which includes firmware versions, serial numbers, anomalous network activity and more — allows Wärtsilä to report to customers accurate and consistent information about their OT environment. This includes information about current project delivery whilst also detailing cyber risks within their environments that need to be addressed allowing both parties to move beyond reactive cybersecurity to a proactive exposure management program.

As OT networks continue to grow, converge with IT and become more complex, they introduce new risks and challenges for the organization to address. Understanding the nuances within the organization and broader industry is key to implementing an effective OT security strategy. All teams — those tasked with securing IT and OT — should have complete visibility of the entire infrastructure and relevant interdependencies. This means knowing exactly which assets exist, their configurations and full situational awareness of both sides of the house, empowering the security team to see and understand the big picture.
