A critical mission: Securing public utility systems
This company manages essential utility infrastructure across more than 100 distributed sites, resulting in a wide attack surface spanning both information technology (IT) and operational technology (OT). With attacks on critical infrastructure rising, the company wanted to strengthen defenses.
The limits of traditional tools
The existing mix of conventional tools for visibility and security monitoring posed numerous limitations:
- Fragmented tools required switching between dashboards to piece together insights
- Multiple tools were required to both identify and take action on potential incidents
- Integration between IT, OT, cloud and email required heavy manual effort
- Existing cybersecurity investments were failing to deliver favorable ROI
A security team of one
For the company’s one-person security team and Vice President of IT, juggling multiple tools and switching between platforms were drains on his time and impacted threat detection and response times. “If an unknown actor attempts to connect to our networks, I need to know immediately and have the ability to stop them before they can do damage.”
Unified, AI-driven defense with Darktrace
The company wanted to unify IT and OT security, reduce manual workload and deliver actionable intelligence in real time. “Darktrace offered the visibility and autonomous capabilities we needed for a proactive defense, including the ability to both see incidents and take action through a single-pane-of-glass.”
Today, the company is using the Darktrace ActiveAI Security Platform™ as the cornerstone of its defense strategy, including:
- Darktrace / EMAIL™
- Darktrace / IDENTITY™
- Darktrace / NETWORK™
- Darktrace / OT™
- Darktrace Cyber AI Analyst™
Real-time protection without the overhead
When compared to a security operations center, the VP said Darktrace is faster, more efficient and more accurate – delivering holistic protection without the high cost or risk of human error.
Darktrace’s Autonomous Response has been a game changer for a shop our size. It stops attacks in real time, before they can move laterally. As a team of one, I can adjust Darktrace’s autonomous actions, ensuring the AI automatically takes stronger actions during off hours to contain threats.”
A single platform for holistic visibility and resilience
Initially licensed under an OT-only pricing model, the company quickly recognized the broader value of Darktrace Self-Learning AI – extending deployment across its IT, cloud, email and endpoint environments and consolidating multiple tools. This holistic visibility is also helping the company to meet ISO and SEC compliance requirements.
A rapid, guided and streamlined deployment
The VP described the Darktrace rollout as smooth and highly collaborative, noting that Darktrace, “Held our hand throughout the process and was genuinely interested in making sure our experience with the platform and the company was top notch.” Despite the complexity of managing multi-connectivity for 100 sites, rollout took less than one week, guided by a clear plan from the Darktrace implementation team.
From barriers to breakthroughs
A seamless security ecosystem
With Darktrace, the company now operates a seamless, AI-driven security ecosystem that combines deep threat validation, intuitive user experience, and a single pane of glass for holistic cyber defense. What began as an OT-focused deployment has grown into a platform that unifies IT, OT, cloud, email and endpoint visibility, delivering comprehensive protection without the overhead of managing multiple tools.
From false positives to real-time, autonomous precision
Since using Darktrace, the company’s false positives have decreased to single digits per day. Within three months, Darktrace conducted 1,470 total investigations, resolving 92% of those autonomously. And Darktrace consistently catches threats that other tools miss:
- When a remote call center agent landed on a malware-laden site using their company device, the company’s endpoint solution failed to catch it. But Darktrace / ENDPOINT detected the malicious traffic in real time, immediately cutting the connection and blocking the machine from the home network – stopping the attack before it could spread.
- Darktrace / EMAIL has consistently flagged suspicious messages other tools missed, including credential harvesters or malware disguised as legitimate emails. “Occasionally users request the release of a legitimate email, whether it’s a blocked link or a message diverted to junk. But 10% of those messages could have caused real harm,” said the VP. “And because Darktrace AI is always learning and adapting, it will identify similar legitimate emails in the future, reducing false positives. That tradeoff is well worth it.”
Time saved, confidence gained
For the VP, one of the biggest benefits is time. In less than one month, Darktrace saved the company 264 analyst hours spent on investigations, only escalating 8% of suspected threats for further review. And with Darktrace’s unified dashboard and real-time monitoring, the VP said, “I no longer have to spend time verifying each security tool is working because I can see everything in one location. And, if there is an issue, Darktrace will let me know. That gives me confidence to let the system handle threats while I focus on other priorities.”
Strengthening OT without complexity
The VP said Darktrace / OT has become one of the most valuable aspects of the deployment. Darktrace / OT provides visibility into firmware levels, PLC communications and unusual device interactions that even dedicated OT tools miss. And using Darktrace, the company can segment OT networks securely while still monitoring them through a single interface, strengthening resilience without adding complexity.
Turning cybersecurity into a business catalyst
By reducing tool sprawl, automating responses, and adapting to the unique rhythms of the organization, Darktrace has transformed the company’s cybersecurity from a constant worry into a reliable foundation.
For us, cybersecurity isn’t just about blocking threats, it’s about building resilience that frees us to focus on growth and innovation. With Darktrace as a trusted partner, we’re no longer stuck reacting to problems; we’re shaping a future where security is a catalyst, not a constraint.”
