Wärtsilä taps Tenable to help solve OT asset management challenges

Tenable®, the Exposure Management firm, 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. Wärtsilä can now answer clients’ queries around asset delivery, cut supply chain risks and take a proactive stance on cybersecurity.

What does the partnership mean for Wärtsilä’s clients?

Wärtsilä will extend the Tenable solution to its customers, allowing them to visualize their own OT environments. Wärtsilä is a global provider of innovative tech and lifecycle solutions for the marine and energy markets and was seeking to address three key challenges:

  • Automated asset inventory collection
  • Compliance reporting — IEC 62443, etc.
  • OT vulnerability reporting

Prior, information was collected manually with the data being reported using spreadsheets. This was time consuming and susceptible to errors and the data could have inconsistencies 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, communicate risk and prioritise action all while enabling its IT, security and OT teams to work better together.

According to Amir Hirsch, General Manager of OT at Tenable, “As operational technology networks continue to grow, converge with IT and become more complex, they introduce new risks and challenges for the firm to address. Understanding the nuances within the organisation 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,” Hirsch further added.

What does the partnership mean for Wärtsilä?

“We tested multiple tools and found Tenable OT Security to have great discovery via vendor specific protocols. The workflow of the tool was a great fit for our own needs but, beyond that, we realized that using the solution allowed us to develop and introduce new services to benefit our customers too,” commented Ross Bailey, Cyber Security Expert at Wärtsilä.

“With Tenable, we can help clients visualize their OT environment. This allows them to adhere to the evolving compliance landscape and assists in protecting critical infrastructure.”

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