As VAROPreem unites two major energy leaders and continues building a resilient, future-ready European energy network, choosing the right technology partner becomes a strategic decision. You need a foundation that is predictable, ready to support growth at scale, and designed to give you clear control over the digital infrastructure your operations depend on.

Open Systems delivers exactly that.

We provide fully managed network and security services built for organizations that operate across multiple countries, regulatory environments, and critical infrastructure sites. Customers with a similar footprint have seen significant reductions in operational cost, major improvements in network performance, and faster NIS2 alignment after standardizing on our unified platform, all while retaining full control over their data and security, fully aligned with Europe’s growing digital sovereignty requirements.

Like VAROPreem, we understand what it takes to run securely in distributed, high-stake, and highly regulated environments. Our operating model spans OT, data centers, hybrid cloud, corporate offices, retail, and bunkering sites — all delivered through one partner, one platform, and one way of working. With over 36 years of handson operational experience, our services are designed not just to function in theory, but to perform in the real world.

Predictable Costs, Zero Surprises

Most SASE and networksecurity contracts hide 30–50% of their real cost in fineprint fees. What looks affordable upfront quickly becomes one of the biggest sources of budget drift: ticket charges, afterhour surcharges, lifecycle refreshes, “premium” support tiers, and a long tail of operationally essential tasks billed as extras.

With Open Systems’ all-inclusive subscription model, the entire hidden-markup layer disappears: we don’t just include what the service needs to run; but also what it needs to actually succeed. Configuration, patching, lifecycle management, 24×7 monitoring, unlimited third-level support, and a dedicated technical team that knows your environment inside out are all part of the service.

The result is true cost certainty, and the elimination of up to 50% in hidden fees that typically show up after signing with a provider. Your costs don’t accelerate from day-to-day operational use, because what other vendors spread across a dozen line items, we deliver in one predictable fee. And because pricing is consistent per site, you can expand 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.

Compliance Without the Compromise

NIS2 compliance is becoming one of the highest-visibility responsibilities for energy executives across Europe. As a leading European energy provider, VAROPreem must maintain a consistently strong compliance posture, especially as EU regulations and sector-specific frameworks continue to tighten expectations.

Open Systems provides a global, audit-ready policy model that applies uniformly across all your sites, countries, and environments. Evidence is consolidated through centralized logging, reducing manual effort, and ensuring alignment with NIS2 requirements.

Because identity-driven access and least-privilege controls are applied the same way across cloud, IT, and OT, you avoid the gaps and inconsistencies that typically trigger compliance findings.

And as a Swiss-governed, European-sovereign security partner, we add an extra layer of assurance: Switzerland’s long-standing independence, stability, and privacy tradition naturally strengthen digital sovereignty ambitions. This gives VAROPreem confidence that both compliance and sovereignty goals can be advanced – without adding complexity.

M&A Integration without the Friction

Uniting two major energy companies is challenging enough, but merging networks, tools, architectures, and operating models across countries, refineries, and critical infrastructure adds an entirely different level of complexity and risk.

Open Systems removes that burden. We give VAROPreem a single, unified foundation for connectivity and security across every environment you operate: refineries, terminals, offices, retail, bunkering sites, cloud workloads, and OT landscapes.

Our team leads the rollout, consolidation, and day-to-day operations. Each site adopts the same secure, standardized model, without pulling your internal teams into integration work or forcing them to reconcile incompatible technologies.

Because everything runs on one platform with consistent controls, future acquisitions stop being multiyear IT projects. They become faster, cleaner, more predictable, and far less resource intensive.

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