Uncover strategies to protect your business after SolarWinds with Darktrace. Get actionable insights for enhanced cybersecurity."

Insights from City of Tyler CIO Benny Yazdanpanahi, who keeps several Texas cities safe in the rapidly evolving and unpredictable threat landscape of today’s world.

The City of Tyler is the largest city in Northwest Texas, with a population of more than 100,000, and home to several major financial, health, and educational institutions. As such, it is an attractive target for cyber-criminals.

Although we were not a full SolarWinds customer, the recent breach illuminated the fundamental flaws in a rules and signatures based security approach. Cyber security must be adaptive for you to mitigate ever-present risk. As IT professionals, I believe we have a responsibility to educate business leaders – and ultimately the SolarWinds attack should serve a wakeup call to all organizations, no matter what providers they use, to reevaluate and strategize security beyond signature-based tooling. Cities must protect constituents from threats that are impossible to predict, often on small budgets and with lean teams. Here is how we do it.

Cyber AI as the key layer to an organization’s security

In order to protect your organization, you have to understand your entire digital enterprise. You have to understand what is happening within your infrastructure. If someone is uploading videos all the time and that is normal, my security technology needs to understand that. Robust security must know that if something comes from a certain resource, in a certain way, then it is okay in that context. But if these parameters subtly shift, it might be an indicator of an active threat. This is where Cyber AI becomes critical – it looks at human and enterprise behavior, and learns and grows with the organization. When something is anomalous, it does that threat investigation and response automatically. And importantly – it’s not black and white.

We originally turned to AI because heuristic tools were limiting. Most security vulnerability comes from people’s behaviors. Although we train our staff about phishing and other vulnerabilities, having an intelligent security solution is necessary. AI has become popular, but Darktrace Cyber AI truly self-learns all the subtleties of our evolving digital infrastructure.

In our Proof of Value with Darktrace Cyber AI, it actually showed us information we didn’t see before with our existing tools, and this proved to be information that was critical to monitor to stay ahead of unseen threats. Armed with Darktrace, we now know what is happening across all our environments, down to if a new device is on the network that isn’t a part of our IT. If anything is deemed a significant deviation from the normal, it is flagged immediately. This is the power of Darktrace’s machine learning. It learns the DNA of your organization and allows you to see what is most pertinent. This is a crucial and necessary ability for every organization. You can buy all kinds of products, but you must understand your network to know which threats you need to pay most attention to.

Being proactive: Fighting threats with AI

At the City of Tyler, we believe that security is layered. It is not enough to just have a firewall. You have to be proactive and have multiple layers. You have to do the basics, like patching software and educating the workforce – but all of this is just one layer of security. What Darktrace does which makes it stand out from the pack, is that it gives us the ability to react and fight back with Autonomous Response. This is critical when working to mitigate risk.

Antigena Email scrubs our email, seamlessly complementing our existing tools and strategy. The AI actually looks at the way people write emails and knows if their style is different. Antigena Email learns the human behind the accounts on City of Tyler’s infrastructure, using Darktrace’s Cyber AI to learn a unique sense of ‘self’ for the city’s email communications. By understanding what is ‘normal’ for every internal user, external sender, and all the complex relationships between them, Antigena Email neutralizes threats before they even reach the city’s users. It is the only tool that intelligently actions threats in the inbox in this way.

Antigena Network provides this proactive protection to the entire infrastructure, no matter the environment. As our employees moved to remote working, understanding what is normal across contexts has been imperative to our cyber strategy. We have a 24-hour staff rotation and I like to be a hands-on CIO, but Antigena, a solution that actually acts on all the information we have, is crucial in securing our city day in and day out. It is our on-going goal to be proactive about threats – Antigena drives this forward.

Stronger security with collaboration

Municipalities generally don’t have large budgets for cyber security, and small cities may have the purchasing power to buy only a few products. With AI achieving so much in one solution, an organization can do a lot with a single technology, as opposed to piling on tools meant to mitigate particular known risks.

We work with other cities, and share our best practices, because we don’t operate on an island by ourselves. We live in a community, and IT is often the catalyst for collaboration. Other smaller cities might not have as many resources, but sharing our use cases and what we think works can help our sister cities. This community collaboration is how we can help. It makes everyone safer.

We are uniquely fortunate in that before the pandemic even happened, most of our staff were already educated on how to use remote working tools. We were always thinking about how we could make the office seamless, but in today’s world, it is becoming imperative to embrace dynamic collaboration. Many organizations are rapidly innovating to be effective whilst remote, and it has opened up a lot of new vulnerabilities very quickly. Cyber AI is perfectly positioned to support this given it is fundamentally adaptable. From virtual deployment to expert SOC handling from a mobile app, Cyber AI is the solution to secure major infrastructure shifts. With the Darktrace Mobile App, I have been able to monitor and protect the organization from anywhere and see what I need to see at the touch of a button.

I have been here for 19 years educating city leaders about new technologies. I believe cyber security resilience comes from three points: people, process, and technology. AI allows these three to work together in combination. With full visibility, you can pinpoint vulnerabilities before they are breached, whether they originate from the people, the process, or the technology. With the ability to respond to threats autonomously, you have a built-in process layer to protect your infrastructure when it counts the most.

Darktrace Named as Market Leader in the 2025 Omdia Market Radar for OT Cybersecurity Platforms

Default blog imageDefault blog image

We are pleased to announce that Darktrace / OT has been named a Market Leader in Omdia’s  2025 Market Radar for OT Cybersecurity Platforms. We believe this highlights our unique capabilities in the OT security market and follows similar recognition from Gartner who recently named Darktrace / OT as the sole Visionary in in the Magic Quadrant for Cyber Physical Systems (CPS) Protection Platforms market.

Historically, IT and OT systems have been managed separately, creating challenges due to the differences of priorities between the two domains. While both value availability, IT emphasizes confidentiality and integrity whereas OT focuses on safety and reliability. Organizations are increasingly converging these systems to reap the benefits of automation, efficiency, and productivity (1).

Omdia’s research highlights that decision makers are increasingly prioritizing comprehensive security coverage, centralized management, and advanced cybersecurity capabilities when selecting OT security solutions (1).

Rising productivity demands have driven the convergence of OT, IT, and cloud-connected systems, expanding attack surfaces and exposing vulnerabilities. Darktrace / OT provides a comprehensive OT security solution, purpose-built for critical infrastructure, offering visibility across OT, IoT, and IT assets, bespoke risk management, and industry-leading threat detection and response powered by Self-Learning AITM.

An AI-first approach to OT security  

Many OT security vendors have integrated AI into their offerings, often leveraging machine learning for anomaly detection and threat response. However, only a few have a deep-rooted history in AI, with longstanding expertise shaping their approach beyond surface-level adoption.

The Omdia Market Radar recognizes that Darktrace has extensive background in the AI space:

“Darktrace has invested extensively in AI research to fuel its capabilities since 2013 with 200-plus patent applications, providing anomaly detection with a significant level of customization, helping with SOC productivity and efficiency, streamlining to show what matters for OT.” (1)

Unlike other security approaches that rely on existing threat data, Darktrace / OT achieves this through Self-Learning AI that understands normal business operations, detecting and containing known and unknown threats autonomously, thereby reducing Sec Ops workload and ensuring minimal downtime

This approach extends to incident investigations where an industry-first Cyber AI AnalystTM automatically investigates all relevant threats across IT and OT, prioritizes critical incidents, and then summarizes findings in an easily understandable view—bringing production engineers and security analysts together to communicate and quickly take appropriate action.

Balancing autonomous response with human oversight

In OT environments where uptime is essential, autonomous response technology can be approached with apprehension. However, Darktrace offers customizable response actions that can be set to “human confirmation mode.”

Omdia recognizes that our approach provides customizable options for autonomous response:

“Darktrace’s autonomous response functionality enforces normal, expected behavior. This can be automated but does not need to be from the beginning, and it can be fine-tuned. Alternative step-by-step mitigations are clearly laid out step-by-step and updated based on organizational risk posture and current level of progress.” (1)

This approach allows security and production to keep humans-in-the-loop with pre-defined actions for potential attacks, enforcing normal to contain a threat, and allowing production to continue without disruption.  

Bespoke vulnerability and risk management

In the realm of OT security, asset management takes precedent as one of the key focus points for organizations. With a large quantity of assets to manage, practitioners are overwhelmed with information with no real way to prioritize or apply them to their unique environment.

Darktrace / OT is recognized by Omdia as having:

“Advanced risk management capabilities that showcase metrics on impact, exploit difficulty, and estimated cost of an attack […] Given the nascency of this capability (April 2024), it is remarkably granular in depth and insight.” (1)

Enabling this is Darktrace’s unique approach to AI extends to risk management capabilities for OT. Darktrace / OT understands customers’ unique risks by building a comprehensive and contextualized picture that goes beyond isolated CVE scoring. It combines attack path modeling with MITRE ATT&CK  techniques to provide hardening recommendations regardless of patching availability and gives you a clearer view of the potential impact of an attack from APT groups.

Modular, scalable security for industrial environments

Organizations need flexibility when it comes to OT security, some want a fully integrated IT-OT security stack, while others prefer a segregated approach due to compliance or operational concerns. The Darktrace ActiveAI Security Platform offers integrated security across multiple domains, allowing flexibility and unification across IT and OT security. The platform combines telemetry from all areas of your digital estate to detect and respond to threats, including OT, network, cloud, email, and user identities.

Omdia recognizes Darktrace’s expansive coverage across multiple domains as a key reason why organizations should consider Darktrace / OT:

“Darktrace’s modular and platform, approach offer’s integrated security across multiple domains. It offers the option of Darktrace / OT as a separate platform product for those that want to segregate IT and OT cybersecurity or are not yet in a position to secure both domains in tandem. The deployment of Darktrace’s platform is flexible—with nine different deployment options, including physical on-premises, virtual, cloud, and hybrid.” (1)

With flexible deployment options, Darktrace offers security teams the ability to choose a model that works best for their organization, ensuring that security doesn’t have to be a “one-size-fits-all” approach.

Conclusion: Why Darktrace / OT stands out in Omdia’s evaluation

Omdia’s 2025 Market Radar for OT Cybersecurity Platforms provides a technical-first, vendor-agnostic evaluation, offering critical insights for organizations looking to strengthen their OT security posture. Darktrace’s recognition as a Market Leader reinforces its unique AI-driven approach, flexible deployment options, and advanced risk management capabilities as key differentiators in an evolving threat landscape.

By leveraging Self-Learning AI, autonomous response, and real-world risk analysis, Darktrace / OT enables organizations to detect, investigate, and mitigate threats before they escalate, without compromising operational uptime.

Fusing Vulnerability and Threat Data: Enhancing the Depth of Attack Analysis

Default blog imageDefault blog image

Cado Security, recently acquired by Darktrace, is excited to announce a significant enhancement to its data collection capabilities, with the addition of a vulnerability discovery feature for Linux-based cloud resources. According to Darktrace’s Annual Threat Report 2024, the most significant campaigns observed in 2024 involved the ongoing exploitation of significant vulnerabilities in internet-facing systems. Cado’s new vulnerability discovery capability further deepens its ability to provide extensive context to security teams, enabling them to make informed decisions about threats, faster than ever.

Deep context to accelerate understanding and remediation

Context is critical when understanding the circumstances surrounding a threat. It can also take many forms – alert data, telemetry, file content, business context (for example asset criticality, core function of the resource), and risk context, such as open vulnerabilities.

When performing an investigation, it is common practice to understand the risk profile of the resource impacted, specifically determining open vulnerabilities and how they may relate to the threat. For example, if an analyst is triaging an alert related to an internet-facing Webserver running Apache, it would greatly benefit the analyst to understand open vulnerabilities in the Apache version that is running, if any of them are exploitable, whether a fix is available, etc. This dataset also serves as an invaluable source when developing a remediation plan, identifying specific vulnerabilities to be prioritised for patching.

Data acquisition in Cado

Cado is the only platform with the ability to perform full forensic captures as well as utilize instant triage collection methods, which is why fusing host-based artifact data with vulnerability data is such an exciting and compelling development.

The vulnerability discovery feature can be run as part of an acquisition – full or triage – as well as independently using a fast ‘Scan only’ mode.

Figure 1: A fast vulnerability scan being performed on the acquired evidence

Once the acquisition has completed, the user will have access to a ‘Vulnerabilities’ table within their investigation, where they are able to view and filter open vulnerabilities (by Severity, CVE ID, Resource, and other properties), as well as pivot to the full Event Timeline. In the Event Timeline, the user will be able to identify whether there is any malicious, suspicious or other interesting activity surrounding the vulnerable package, given the unified timeline presents a complete chronological dataset of all evidence and context collected.

Figure 3: Pivot from the Vulnerabilities table to the Event Timeline provides an in-depth view of file and process data associated with the vulnerable package selected. In this example, Apache2.

Future work

In the coming months, we’ll be releasing initial versions of highly anticipated integrations between Cado and Darktrace, including the ability to ingest Darktrace / CLOUD alerts which will automatically trigger a forensic capture (as well as a vulnerability discovery) of the impacted assets.
