As VAROPreem unites two major energy leaders, choosing the right partners becomes more important than ever. You need a solid foundation that can support you in expanding a resilient, sovereign, and future-ready European energy network.

Open Systems delivers exactly that. –> Can’t be bothered to read? Let’s talk instead.

We provide fully managed connectivity and security built for complex, highly regulated, critical-infrastructure environments. Customers with similar scale have cut costs, improved performance, and accelerated NIS2 compliance on our unified platform, all while retaining full data and security control.

After 35+ years of real-world operations, we understand what it takes to run securely in distributed, high-stakes environments, and we’re ready to support VAROPreem as you move into your next chapter.

Compliance Without the Compromise

NIS2 and digital sovereignty are rising to the top of the agenda for Europe’s energy sector. VAROPreem needs a strong, uniform compliance posture as EU and sector rules tighten.

Open Systems delivers one audit-ready policy model across all sites, with centralized evidence and consistent identity-based controls across cloud, IT, and OT.

As a Swiss-governed, European-sovereign security partner, we strengthen both compliance and sovereignty goals without adding complexity.

Predictable Costs, Zero Surprises

Most SASE and network-security contracts hide 30–50% of their real cost in fine-print fees: All of those operationally essential components that turn out to be billed as “extras”.

With Open Systems’ all-inclusive subscription model, the hidden layer disappears. We not only include what the service needs to run, but also what it needs to succeed. Configuration, patching, lifecycle management, 24×7 monitoring, unlimited third-level support, and dedicated success engineers are all part of the basic service, resulting in true cost certainty. And because pricing is consistent per site, expansions can be done without consulting projects and renegotiation cycles: You simply onboard the next location.

In an industry defined by volatility and factors you can’t control, Open Systems makes sure your network security costs aren’t one of them.

M&A Integration without the Friction

Merging two major energy companies creates massive complexity, especially across networks, tools, and critical infrastructure.

Open Systems removes that burden by giving VAROPreem one unified foundation for secure connectivity across refineries, terminals, offices, cloud workloads, retail, bunkering, and OT. We lead rollout, consolidation, and operations, so every site adopts the same secure model without straining internal teams. With one platform and consistent controls, future acquisitions shift from multi-year IT projects to fast, predictable integrations.

It’s an M&A-ready architecture built for VAROPreem’s new scale, engineered to support integration today and expansion tomorrow.

–> Keen to reduce complexity? It’s all in the white paper.
