Infrastructure and the services on top of it, since 2012
We run the machines, and everything on them.
For Austrian businesses that means servers, MS365, NextCloud, database clusters, backup, MDM, networking and AI: fully managed, ISO 27001 certified, with your data inside the EU.
For institutional participants in decentralised networks it means Ethereum validator nodes on our own hardware at three sites in Austria. The same craft, two very different customers.
Based in Stockerau, Lower Austria since 2012. You know who runs your infrastructure, and you do not end up in a ticket system on another continent.
Fully managed IT
Servers, endpoints, MS365, NextCloud, backup, MDM and network: we run all of it. You focus on your business.
Data inside the EU
Our own data centre in Austria, Proxmox, NextCloud and Linux stacks, clear data flows. No CLOUD Act, no grey areas.
ISO 27001 certified, NIS2 prepared
Risk management, logging and incident plans are daily work for us, not a project. What the regulator expects, we already enforce on ourselves and bring into your setup.
AI with substance
Claude or another strong model, RAG over your documents, local models. Introduced pragmatically, with clear confidentiality and GDPR limits.
DevOps and open source
We build software ourselves, from Stereum to StereumLabs. The same automation discipline goes into your infrastructure.
About us
Read more →Who we are
RockLogic is a self-funded, multinational team of IT experts based in Stockerau (Korneuburg district, Lower Austria). Since 2012 we run IT infrastructure, software development and specialised validator hosting for Ethereum. With our own data centre in Austria, ISO 27001:2022 certified, and independent of US hyperscalers.
What we do
From the first laptop to servers, MS365, NextCloud, backup, firewalls and GDPR-compliant AI: we build, run and document it from one hand, automated and supported around the clock when you need it.
We are small enough to know you personally and large enough to address compliance, growth and downtime contractually.

Ethereum infrastructure
Node operations: validator infrastructure for decentralised networks
Since 2020 we have been running nodes that verify transactions on the Ethereum network and co-sign the consensus. With our own open-source software (Stereum), our own data centre in Austria and institutional partners such as Lido, Obol and SSV. A business line of its own, serving different customers than our SME practice, built on the same data-centre discipline.
