Your cyber defense advantage
A distributor by structure. A technical partner in practice.
Yellow Cube brings global vendor innovation, hands-on engineering and a clear architecture for securing digitally sovereign networks across Central and Eastern Europe.
We do not sell a crowded catalogue. We help partners and organizations understand the operating capability they need, prove the technology in real conditions and keep expert support available after the purchase.
Built through partners
Customer projects are delivered with the local integrator or service provider—not around them.
Backed by engineers
Architecture, proof-of-concept work, training and escalation remain part of the engagement.
From the field · Cyber defense proving grounds
Ideas, tools and architectures under real load—in the open, with the people building them.

European & trusted cybersecurity
Credibility you can verify.
We prioritize technologies whose ownership, supply chain and certifications can withstand scrutiny. Stormshield—the flagship network-security vendor of Airbus CyberSecurity—is the longest-standing example of that approach in our portfolio.
Instead of a full-screen vendor video, the proof belongs next to the claim: deployed scale, trained engineers and certifications that matter in regulated environments.

Anatomy of the Treasury breach
When the actor behind the Magyar Államkincstár intrusion published 24 screenshots from inside the network, our team rebuilt the whole thing from the timestamps baked into them: 5.5 days from a nine-year-old WebLogic CVE to a public leak, across an inter-forest trust nobody was watching.
Every step of the attack chain is paired with the control that would have stopped it — and we show why the headline figure of 229.1 TB was never going out the door.
Straight answers
Questions partners and customers actually ask.
The operating model matters as much as the technology. These are the boundaries we make explicit before a project starts.
01What is Yellow Cube’s role in a customer project?+
We are a distributor by structure, with the technical depth most distributors do not maintain. The local partner owns the customer relationship. Yellow Cube adds vendor selection, architecture, pre-sales engineering, training and the SOC behind managed services.
02Does the Stormshield footprint mean Yellow Cube is mainly a firewall distributor?+
No. Stormshield is our longest-standing vendor and the largest by deployed footprint, but the portfolio covers the full stack—from identity, endpoint and email to OT, threat intelligence, validation and security operations. The requirement leads; the catalogue follows.
03What does trusted, sovereign-grade cybersecurity mean in practice?+
It means technologies that can withstand government, military, ownership and supply-chain scrutiny. Certifications such as NATO Restricted, EU Restricted and Common Criteria provide useful evidence when jurisdiction and long-term control matter.
04What happens when an end customer contacts Yellow Cube directly?+
The lead goes to the partner best matched to the customer’s geography, sector and size. Yellow Cube operates through the channel and does not undercut registered partner opportunities.
