OVERVIEW
Founded in 2005, DTEK is Ukraine’s largest private energy company. They power millions of homes and businesses through coal and natural gas extraction, thermal, solar, and wind generation, electricity distribution, retail supply, and wholesale energy trading. With over 55,000 employees, four data centers, more than 2,000 servers (just under 90% virtualized) and a growing public-cloud footprint, DTEK’s digital ecosystem is part of the nation’s critical infrastructure.
“Keeping Ukraine’s lights on is a mission that leaves no room for cyber compromise. Our security must be as resilient as our energy network,” notes the Head of Information Security Department at MODUS X (DTEK Group), underscoring why comprehensive security became an urgent strategic priority.
Cybersecurity and IT resilience across DTEK’s infrastructure are ensured by MODUS X — the Group’s dedicated internal company focused on enterprise IT and cybersecurity solutions.
With single, unified and consolidated Trend platform, we gained end-to-end visibility—from particular behavior on each workplace and covered services, including Microsoft 365 and Kubernetes, to hybrid-environment datacenters—so we can neutralize threats before they disrupt the energy supply.

CHALLENGES
Once adequate for eliminating a wide variety of malware, DTEK’s legacy endpoint detection and response toolset faltered against the multi-stage, intelligence-driven attacks now targeting critical infrastructure. Compounding the issue, security analysts had to juggle separate consoles for endpoints, servers, email, and cloud services.
“We were staring at hundreds of alerts a day with no unified context. Legacy tools left blind spots we simply couldn’t tolerate when nation-state adversaries probe our grid every day,” says the Head of Information Security Department at MODUS X (DTEK Group).
On the operational side, budget predictability suffered. Each new security service required a separate license SKU, leading to cost overruns and protracted procurement cycles—an unacceptable friction point in a military-time economy. DTEK needed a single, scalable solution that combined XDR-level analytics, hybrid-cloud reach, and more flexible licensing to accelerate protection without ballooning complexity or cost.
[With Trend Vision One,] we’ve cut investigation time by more than a third and expanded protection across every workload, all while simplifying our toolset.

WHY TREND
A rigorous proof of concept (PoC) with several leading vendors shows Trend delivering unmatched detection quality and scalability across on-premises and cloud assets. “Trend outperformed every competitor and backed it up with local experts who understand both our environment and our urgency,” says the Head of Information Security Department at MODUS X (DTEK Group). The platform’s comprehensive coverage and extensive roadmap, which includes concept of zero trust network access (ZTNA) and interaction control instruments with AI-platforms, aligns perfectly with DTEK’s hybrid architecture and long-term strategy.
SOLUTION
DTEK implemented an integrated stack consisting of on‑premises solutions and cloud services from Trend Vision One to bring risk visibility, evaluation, and prioritization.
This includes Trend Apex One for desktop malware protection, Deep Security to secure critical workloads, and Email and Collaboration Security to analyze and prevent threats in Microsoft 365 services. The Deep Discovery suite provides deep analysis of suspicious objects by sandboxing them to detect targeted attacks. Additionally, Trend Vision One™ Container Security tracks and prevents threats in service development, while Trend Vision One™ Cyber Risk Exposure Management (CREM) predicts and surfaces potential cyberattacks at early stages, enabling proactive responses.
“With single, unified and consolidated Trend platform, we gained end-to-end visibility— from particular behavior on each workplace and covered services, including Microsoft 365 and Kubernetes, to hybrid-environment datacenters— so we can neutralize threats before they disrupt the energy supply,” observes the Head of Information Security Department at MODUS X (DTEK Group).
The platform’s flexible credit-based licensing also lets DTEK scale protection on demand.
RESULTS
Since deploying Trend, behavioral analytics and in‑memory detection block advanced threats at the earliest stage, investigation times have dropped by roughly 35% thanks to correlated telemetry provided by Trend Vision One. “We’ve cut investigation time by more than a third and expanded protection across every workload, all while simplifying our toolset,” reports the Head of Information Security Department at DTEK.
A single-platform approach now secures Microsoft Windows, Linux, and macOS environments, as well as public clouds and Kubernetes R&Ds. Audit-ready reports streamline compliance and elastic licensing keeps costs predictable.
WHAT'S NEXT
Looking ahead, DTEK will extend Trend protection to additional Kubernetes clusters, run PoC of Trend Vision One™ Zero Trust Secure Access (ZTSA) to secure remote operations. Additionally, they plan to cover critical OT environments by leveraging Trend Vision One attack‑surface-risk-management modules for continuous posture improvement.
“Trend is now our strategic cybersecurity partner,” concludes the Head of Information Security Department at MODUS X (DTEK Group). “Next, we’re rolling out Kubernetes more roadly and implement ZTNA protection to stay ahead of an ever-evolving threat landscape.”
