DER Security Corp is delivering a revolutionary technology capable of securing Distributed Energy Resources (DER) and the energy grid against the world’s most sophisticated adversaries.
Born from the standards-setting organizations that built the distributed energy grid. Our founders didn’t just implement SunSpec Alliance and Sandia National Laboratories protocols — they architected them. With proven leadership from AutoGrid (DERMS/VPP), NTT, and IBM, plus successful M&A and exit experience, DERSec delivers enterprise-grade security that’s protocol-native at its core.
Our founders don’t just understand the protocols — they wrote them. That depth of standards expertise combined with proven enterprise execution is what makes DERSec uniquely positioned to secure the distributed energy revolution.
Years architecting the communication standards that power today’s DER ecosystem
Of distributed energy deployments worldwide rely on communication standards pioneered by our founding team
Founding leadership in SunSpec Alliance, IEEE 2030.5, and grid interoperability protocols worldwide
By building cybersecurity that’s as native to the grid as the standards that define it. The energy transition is the most critical infrastructure shift of our lifetime. As central power plants are replaced by millions of solar inverters, batteries, and electric vehicles, the grid’s attack surface is exploding. DERSec exists to secure this new landscape.
We envision a future where distributed energy resources are not just clean and efficient, but inherently resilient against the evolving threat landscape — where every solar inverter, battery, and EV charger is monitored, protected, and trusted.
Our leadership team combines decades of experience across energy systems, national laboratories, cybersecurity, and enterprise technology — united by a shared mission to secure the distributed energy revolution.
Tom Tansy is the CEO and co-founder of DER Security Corp (DERSec), where he leads the company’s strategic vision and technical direction. A serial entrepreneur, Tom previously founded several companies that achieved successful exits to Microsoft and Cisco before turning his focus to the energy sector. He went on to found the SunSpec Alliance, the industry consortium he helped grow into an internationally recognized standard body, defining interoperability standards — including SunSpec Modbus and IEEE 2030.5 — for solar, storage, and other grid-edge devices. Tom’s rare combination of enterprise technology pedigree and deep energy standards expertise gives DERSec a strong foundation at the intersection of cybersecurity and the modern grid edge.
