Nozomi says Trustpower, a leading New Zealand power, gas, broadband and phone company, had already invested heavily in its security systems, focusing on areas such as prevention and firewalls, “but this traditional approach offered little-to-no visibility into what was really happening in the network”.
“As we continued to expand, digitise and add to our operational environment, this lack of visibility presented a major challenge,” said Marty Rickard, Delivery Manager - Operational Technology, Trustpower.
“We needed a new approach to cut through the noise, gain real insights into our network and ensure we were protected from cyberattacks.”
Nozomi says Guardian, a monitoring solution that protects control networks from cyberattacks and operational disruptions by providing complete industrial control system (ICS) visibility and security in a single solution, was chosen by Trustpower after a competitive bidding process.
“Guardian was put to the test in a lab environment where it was able to capture live traffic and see virtually all devices in the network and how they communicated. The system was tested with up to five times its node capacity and was still able to deliver results, providing never-before-seen insights into Trustpower’s network and a near-complete asset register in minutes,” Nozomi said.
“Now deployed across Trustpower’s operational network, Guardian provides deep asset discovery, inventory and operational visibility; automatic real-time notification of industrial events of interest, including alerts triggered by custom-designed rules and constraints; and traffic analysis for current and future investigations,” says Nozomi.
The announcement comes as cybersecurity awareness and governance become a higher priority in New Zealand, with the Government’s Communications Security Bureau (GCSB) recently launching a resource for company boards to help improve cybersecurity governance, following an assessment of cybersecurity resilience across 250 of New Zealand’s nationally significant organisations.
“Nozomi Networks has enabled us to meet New Zealand’s Voluntary Cyber Security Standards for Industrial Control Systems (VCSS-OCS),” said Matt van Deventer, Head of Technology, Trustpower.
“Maintaining and exceeding these standards is a key priority for Trustpower and Nozomi Networks enables us to comfortably achieve that.”
“Cyber security – like cybercrime and the threat landscape – needs to continually evolve,” said Andrea Carcano, Nozomi Networks Co-founder and Chief Product Officer.
“New Zealand businesses need visibility into their networks and awareness of who has access, and to what extent, to ensure they are protected. Advanced OT-IoT visibility and security technology is essential to achieve this. Trustpower recognises that and has now created a better operating environment for its business, customers and third-party suppliers.”
