Power grid operators can use PatchAssure to leverage Doble's extensive cybersecurity experience and expertise. Doble's PatchAssure ensures that all types of updates are accounted for including: security, functional, and workarounds.

"There is a gap in cybersecurity that leaves critical substations vulnerable to attack," said Gowri Rajappan, director of technology and cybersecurity at Doble. "Assets that are in remote substations often go unpatched and provide the type of opportunity hackers are looking for to gain access to a network. Using our in-depth knowledge of the asset management work processes, we've responded with PatchAssure to give utilities an effective and easy-to-use update management tool."

Doble PatchAssure also delivers the following benefits:

  • Offers an efficient, cost-friendly and turnkey program for strained internal teams, especially in identifying and deploying security and software patches from a variety of vendors.
  • Manages risk quickly and allows asset managers to redirect focus on more complex field tasks due to fast and accurate vulnerability and patch detection.
  • Reduces infrastructure and resource costs by addressing all aspects of patch management, from discovery to delivery, and all substation devices such as relays and network switches.

On-demand provision of extensive evidence for every aspect of the patch management process makes Doble PatchAssure the ideal solution for NERC CIP compliance. With the consistent and reliable monitoring capabilities of PatchAssure, utilities can focus on the complexities behind grid operation.
