We build, configure and deploy private, on-premises, or air-gapped AI solutions on your dedicated hardware or secure virtual server. Designed for Irish businesses handling confidential data and trade secrets. Zero cloud leakage. 100% GDPR accountable.
We install and secure offline AI on existing machine. OS configuration, local LLM deployment, firewall hardening.
A turnkey build including hardware assembly, software setup, 3-day testing (optional, at no extra cost), and delivery.
Annual review of your server book, physical security seals, and network logs. We provide a comprehensive evidence report, including photographic proof and system snapshots for your Data Protection Officer (DPO) and insurance records. We verify the hardware and software compliance for your GDPR audits (staff training remains your responsibility based on your specific industry guidelines).
Continuous system health checks and critical security updates. This is included at no extra cost for our clients, as maintaining a secure, stable environment is our baseline standard, not a paid upsell.
For any requested, non-routine work, hardware repairs, or custom configurations. Billed transparently based on agreed-upon time.

ClosedNode is a specialized IT infrastructure service operated by Etonator (CRO Reg. No. 794031), based in Kilmallock, Limerick. We operate on a strict Zero Trust policy: we do not ask you to trust our word. We provide physical, verifiable proof of your system's security.
To guarantee this transparency, we build our systems primarily on open-source software.
Zero-knowledge policy. We don't access, view, or store your customers' personal data. Security first.
We assess your data security requirements and provide a precise, transparent infrastructure blueprint (physical or virtual) tailored to your specific workload and compliance needs.
We build and harden the system in our controlled environment. This includes OS installation, AMD or NVIDIA GPU tuning, local LLM (Large Language Model) deployment, and strict network isolation (e.g., encrypted VPN and outbound firewall blocking).
Upon deployment, we provide a signed "Server Book" (maintenance log), cryptographic software hashes, and secure system snapshots. For strict air-gapped builds, we also apply physical tamper-evident seals. This creates a permanent, verifiable record for your GDPR audits, with all annual maintenance checks jointly signed by our technician and your designated representative.
We leverage local, open-source AI tools in our own workflow to ensure efficiency and precision. The systems we deliver to you are configured for maximum data protection based on your specific business needs. Whether fully offline or securely network-isolated, we eliminate unnecessary telemetry and external dependencies by default.
