Infrastructure. Intelligence. Independence.

We build systems that keep working when everything else stops. On-premises AI, industrial control, and infrastructure designed for independence.

Lead Offering

On-Premises AI Integration

Run 70B-class language models on your own hardware. No cloud dependency, no data leaving the building. We assess your needs, design the architecture, deploy a working pilot, and hand you the keys.

For Whom
Organizations handling sensitive data — legal, medical, financial, government — who want AI without cloud exposure. Anyone concerned about GDPR, data sovereignty, or vendor lock-in.
Evidence
Running 70B-class Llama models locally on a single workstation with full desktop workload. Production-proven AI workflows across dozens of projects. No cloud dependency whatsoever.

How It Works

  • Needs assessment — we map your workflows, data sensitivity, and hardware to determine the right model and architecture
  • Architecture design — local inference stack tailored to your environment, with security and maintenance in mind
  • Pilot deployment — working system installed on your hardware, tested with your actual use cases
  • Handoff — full documentation, operations manual, and training for your team. You own everything.

Deliverables

  • Needs assessment report
  • Architecture design document
  • Working pilot installation on your hardware
  • Operations manual and team training
  • Post-deployment support period
Timeline
2–4 weeks, assessment through pilot handoff
Investment
From 1.5M HUF, depending on scope and complexity

In Practice

A single workstation running 70B-parameter language models locally, handling full desktop workload in parallel — no cloud calls, no data leaving the premises. Deployed for production use across multiple knowledge-intensive workflows, replacing cloud API dependencies entirely.

SCADA / ICS Modernization

Legacy SCADA systems are a ticking clock — aging software, security gaps, lost institutional knowledge. We analyze your current state, identify risks, and design a migration path. No downtime. No disruption.

For Whom
Industrial operators running aging control systems — water management, manufacturing, energy. Contractors serving critical infrastructure clients.
Evidence
Complete SCADA modernization delivered for active critical infrastructure. Proven zero-downtime parallel-running methodology. 20+ years in industrial systems.

How It Works

  • System analysis — full documentation of current SCADA/PLC architecture, communication protocols, and software stack
  • Risk assessment — security vulnerabilities, obsolescence risks, single points of failure, institutional knowledge gaps
  • Migration roadmap — phased plan with technology recommendations, cost structure, and risk mitigation for each stage
  • Parallel-run implementation — new system runs alongside the old one until proven, then cutover. Zero surprise downtime.

Deliverables

  • Comprehensive system analysis report
  • Risk and vulnerability assessment
  • Technology stack recommendation
  • Phased migration roadmap with cost estimates
  • Implementation available separately
Timeline
Assessment: 2–3 weeks · Implementation: 3–6 months
Investment
Assessment from 1M HUF; implementation quoted separately

In Practice

A critical infrastructure water management operator with 11 remote PLC stations needed their legacy SCADA system assessed before NIS2 deadlines. We delivered a comprehensive system analysis covering architecture, communication protocols, security gaps, and a phased migration roadmap — without a single hour of unplanned downtime.

NIS2 Readiness & OT Security

NIS2 deadlines are here and most organizations aren't ready. We help you prepare — practical gap analysis, security hardening, and the documentation you need before the auditors arrive. Not a checkbox exercise.

For Whom
Critical infrastructure operators and their contractors preparing for NIS2 compliance. Water management, energy, transport, manufacturing. Anyone who needs to get audit-ready.
Evidence
9 ITSEC planning documents authored covering IEC 62443, ISO 27001/27019, and NIS2 mapping. Hands-on OT security hardening across production SCADA systems. Presented at Magyar Hidrológiai Társaság.

How It Works

  • Current state assessment — mapping your IT/OT landscape, existing security measures, and organizational readiness
  • Gap analysis — systematic comparison against NIS2 requirements, IEC 62443, and applicable standards
  • Prioritized remediation plan — what to fix first, what's critical vs. nice-to-have, realistic timelines
  • Documentation preparation — the evidence package your auditors will need to see

Deliverables

  • NIS2 gap analysis report with severity rankings
  • Prioritized remediation roadmap
  • Security hardening implementation guidance
  • Compliance documentation package
  • Ongoing support available for remediation phase
Timeline
1–3 weeks depending on scope
Investment
From 800K HUF, depending on scope

In Practice

Authored 9 ITSEC planning documents for a critical infrastructure operator, mapping IEC 62443 zones/conduits, ISO 27001/27019 controls, and NIS2 requirements to their actual OT environment. Hands-on security hardening across production SCADA systems — not theoretical compliance, but tested configurations on live infrastructure.

Infrastructure Architecture & Hardening

You've outgrown the single server. We audit your infrastructure, find the single points of failure and security gaps, then design and build something production-grade.

For Whom
Growing organizations with fragmented infrastructure. Companies preparing for compliance audits or scaling operations.
Evidence
Scaled single-office setup to 10-server enterprise supporting 300+ users. Docker-first architectures, multi-tier security, 1PB+ managed storage with automated backup.

How It Works

  • Infrastructure audit — full inventory of servers, networking, storage, backup, monitoring, and security posture
  • Risk and bottleneck analysis — single points of failure, capacity limits, security gaps, compliance readiness
  • Redesign proposal — target architecture with technology choices, migration path, and effort estimates
  • Implementation — hands-on build-out available, or detailed enough specs for your team to execute

Deliverables

  • Infrastructure audit report
  • Architecture redesign proposal
  • Implementation plan with phases and priorities
  • Monitoring and backup strategy
  • Hands-on implementation available separately
Timeline
Audit + design: 2–3 weeks
Investment
Audit + design from 1M HUF; implementation quoted separately

In Practice

Scaled a single-office setup into a 10-server enterprise architecture supporting 300+ users. Docker-first containerization, 802.1X network access control, multi-tier security zones, VPN mesh, automated monitoring, and 1PB+ managed storage with automated backup — built incrementally without disrupting daily operations.
