overcyte
Our story.
Overcyte is a cyber risk and compliance platform built in New Zealand for critical infrastructure. It’s used by operators across New Zealand, Australia and the UK.
Our founder, Aaron Gayton, spent 20 years protecting the systems that run power and water networks. He kept seeing the same problem. Cyber risk was managed in spreadsheets and scattered processes, using tools that were never designed for these environments.
So we built one that was. Overcyte helps teams understand their risk, check their progress against frameworks like AESCSF and NZ MCSS, and report clearly to their board. It covers the whole year, not just audit season.
Today Overcyte is used by lines companies including Northpower, Top Energy, Electra, EA Networks and vGRID, as well as Coastguard and The Warehouse Group. Our goal is to help them protect the essential services their communities rely on every day.
