DigiCert to Supply Digital Certificate Infrastructure for Australia's National Energy PKI
By News Desk ·
Key takeaways
- DigiCert was selected by Australia's National Energy PKI to provide digital certificate infrastructure for rooftop solar and battery systems.
- More than 4.2 million Australian homes have rooftop solar, and 44 manufacturers accounting for about 94% of the market have been onboarded.
- The deployment uses the CSIP-AUS standard and DigiCert Device Trust Manager, which can move to quantum-resistant cryptography.
DigiCert has been selected by Australia's National Energy Public Key Infrastructure to provide the digital certificate infrastructure that lets rooftop solar and battery systems communicate securely with electricity distribution networks across Australia. GlobeNewswire announced the selection on November 1, 2026.
How the National Energy PKI Deployment Works
DigiCert is a privately held provider of public key infrastructure and digital trust services, founded in 2003 and headquartered in Lehi, Utah. The initial deployment will help devices and network operators verify each other's identities and help protect the data and emergency control commands they exchange.
The National Energy PKI was established as a not-for-profit to provide a consistent national framework for digital identity in the energy sector. This first use case creates a common way for energy devices, manufacturers, distribution network operators, energy retailers, and technology providers to authenticate and communicate securely within the ecosystem. Since launch, 44 solar and battery manufacturers have been onboarded and account for approximately 94% of the Australian market.
Following a rigorous selection process, the National Energy PKI selected DigiCert to provide the expertise and PKI infrastructure to support secure communications under the Common Smart Inverter Profile-Australia standard, enabling consistent device authentication across participating networks.
"Australia's energy transition has moved quickly, and the cybersecurity systems supporting it are now set up to keep pace," said Naomi Wynn, CEO of the National Energy PKI. "With millions of devices connecting to our electricity grid, Australia must have a harmonized, sovereign and cyber secure approach."
Daniel Sutherland, Area Vice President, ANZ at DigiCert, said the company's Device Trust Manager "is helping lay a shared foundation that automates certificate renewals and can move to quantum-resistant cryptography without being rebuilt."
DigiCert's Scale Behind the Energy Contract
According to akta.pro company records, DigiCert serves more than 90% of the Fortune 500 across 180 countries and secures more than 3 billion identities through its DigiCert ONE platform. The same records list five funding rounds, the most recent a $9.3 million debt-funded round in October 2025 led by Runway Growth Capital. DigiCert's revenue is estimated at $500 million to $1 billion, with a valuation estimate of $5 billion to $10 billion.
Earlier DigiCert Moves in 2026
DigiCert launched Quantum Central, a tool for managing post-quantum cryptography transitions, now generally available as part of DigiCert ONE, SecurityBrief Australia reported in October 2026. That month, DigiCert also achieved ISO/IEC 27001:2022 certification for its information security management system supporting global certificate operations, covering 11 countries and over 125,000 customers, SecurityBrief Australia reported.
In September 2026, Newfold Digital selected DigiCert to provide SSL/TLS certificate infrastructure for its Bluehost and Network Solutions businesses, covering services used by about 6 million customers, Channellife reported.
What Comes Next for the Energy PKI
The National Energy PKI is delivered by funding from distributed network operators and by the Australian Renewable Energy Agency. DigiCert said the deployment can move to quantum-resistant cryptography without being rebuilt.
