Darktrace PREVENT™

PREVENT empowers the CISO and the security team to reduce cyber risk by continuously monitoring the organization’s internal and external attack surface, highlighting and prioritizing risks, and then autonomously hardening defenses as part of Darktrace’s Cyber AI Loop. PREVENT, which is now generally available, is already proving its value to early-adopter customers. 

“We know that the bad guys are gaining knowledge every day. We need to as well. And I think that this type of proactive approach is a requirement now. I don’t think it is an option,” said Jim Davies, the Director of IT at US supply chain management company Ongweoweh.

PREVENT brings together several capabilities, including attack surface management, attack path modeling, breach and attack emulation, and pentest augmentation. By combining these into one end-to-end solution, the system and the humans who use it benefit from a full understanding of which countermeasures will mitigate risk to the greatest extent. 

While the security team works on these countermeasures, PREVENT feeds its findings into Darktrace’s DETECTTM and RESPONDTM capabilities, which in turn harden defenses by heightening their sensitivity around risky assets. This happens autonomously, so the human security team can prioritize other work while the AI continuously hardens the security stack.

Surfacing Risks on the External Attack Surface

The Darktrace PREVENT product family currently consists of two interconnected modules: PREVENT/Attack Surface ManagementTM (ASM) and PREVENT/End-to-EndTM (E2E). 

PREVENT/ASM uses AI to distinguish the company’s external assets on the internet, while only requiring the company’s brand name as input. Early adopters saw it reveal 30-50% more assets than they realized they had. 

“As early as the proof of concept, there was demonstrated value with PREVENT which revealed some attack surface opportunities that none of our other security providers had come across.” said Jenny Moshea, Direct of Technology for Sellen Construction.

PREVENT/ASM is now being adopted by organizations large and small across a number of industries, revealing a wide range of surprising risks and vulnerabilities the security team was not previously aware of. 

In one trial at a utilities organization, PREVENT/ASM identified unexpected access to a control system that was mission critical and could potentially impact the water facilities. Another customer was testing a new project in a cloud environment that was not meant to be publicly visible, let alone accessible. After PREVENT/ASM revealed that sensitive data was exposed and at risk of falling into the wrong hands, the security team was able to proactively get ahead of this risk by reconfiguring the system. 

A Level Deeper: An Internal View of Risk

While PREVENT/ASM examines a company’s external assets, PREVENT/E2E leverages the AI understanding of a company’s internal digital infrastructure. This industry-first product consolidates and optimizes several risk management capabilities, including attack path modeling, pentest augmentation, breach and attack simulation, security awareness training, and cyber risk prioritization. 

One early adopter benefited from PREVENT/E2E’s evolving insights, finding that it filled in the gaps of unknown risk between pentests.   

“We’ve run pentests maybe four times a year, that’s at that point in time. We go correct those issues and then we’re basically waiting for the next one before we dig into it. As soon as we saw the tool, we were like wow this is a continual test every day, we’re able to go take a quick peek, see what’s going on out in the environment,” said Mike Sherwood, the Chief Information Officer for the City of Las Vegas.

After assessing the exposure, likelihood, and potential damage of every single device and attack path in the organization, PREVENT/E2E uncovered a major risk in one customer’s environment:  a patch had failed to install on the disaster recovery domain controller – a vulnerability which the security team had not previously been aware of. With PREVENT’s findings, the team was able to quickly address and close this significant risk. 

Another customer deployed PREVENT/E2E and discovered that the building’s air conditioning system was accessed by an account that had domain admin privileges. PREVENT/E2E informed the security team of this configuration, which would have allowed a threat actor easy lateral movement after targeting the IoT device. 

An End-to-End Solution

Having established the most critical attack paths, PREVENT/E2E enables customers to test the validity of these attack paths through emulated attack campaigns. One customer was amazed to discover that the technology had learned the idiosyncrasies of a user’s communication patterns and launched an emulated social engineering attack that reflected the common spelling mistakes of the user being impersonated. 

By learning how susceptible users are to social engineering attacks, the system gains an even better idea of how likely a particular attack path is, and factors this into the prioritization of its risk mitigation advice. This is yet another indicator of how combining different preventative cyber security measures into one solution gives the security team the insights they need to take practical, effective action to reduce cyber risk. 

PREVENT has already boosted the cyber security postures of its early adopters, surfacing misconfigurations, brand abuse, shadow IT, and other significant risks. 

“PREVENT is an incredibly helpful way to understand risk, particularly when comparing changes over time,” said Klint Price, the Head of Technology & Cybersecurity at facilities management company Vixxo. “Understanding vulnerabilities is one thing, but actually being able to digest and prioritize them is even better.”

Darktrace named a Leader in the 2026 Gartner® Magic Quadrant™ for Network Detection and Response (NDR) For the Second Consecutive Year

garnter ndr magic quadrantDefault blog imageDefault blog image

Continued recognition in NDR  

Darktrace has been recognized as a Leader in the 2026 Gartner® Magic Quadrant™ for Network Detection and Response (NDR), marking the second consecutive year in the Leaders quadrant.

We believe this consistency reflects sustained ability to execute, adapt, and deliver outcomes as the market evolves.

While we are immensely proud to be recognized by industry analysts as a Leader in NDR, that's just part of the story. Darktrace was also Named the Only 2025 Gartner® Peer Insights™ Customers’ Choice for Network Detection and Response based on direct customer feedback and real-world experience.

We believe the combination of these two signals is important. One reflects how the market is evaluated. The other reflects how technology performs in practice.

Why Darktrace continues to be recognized as a leader

We believe our position as a Leader for the second consecutive year reflects a combination of our sustained ability to execute in NDR, continued AI innovation, and proven delivery of security outcomes for customers and partners worldwide.

We also feel that our leadership in the NDR market is a testament to our unique and multi-layered AI approach, for which we were recognized as No.7 on Fast Company’s Most Innovative AI Companies of 2026 list, plus one of the hottest AI cybersecurity companies in CRN's AI 100.

Adapting to complex, real-world environments

Organizations are no longer protecting a single network perimeter. They are securing a mix of users, devices, applications, and data that move across hybrid environments.

Darktrace has focused on maintaining visibility and detection across these conditions, allowing security teams to understand activity as it scales.

Supporting organizations globally, not just technically

Security outcomes are shaped as much by deployment and support as they are by detection capability.

Darktrace continues to invest in regional presence across 29 countries around the world, helping organizations operationalize NDR in ways that align with local requirements, internal processes, and team structures.

Continuing to push AI beyond detection

AI in cybersecurity is often positioned as a way to improve detection accuracy. But the more important shift is how AI can influence decision-making and response.

Darktrace continues to develop models that learn from both live environments and historical incident data, combining real-time behavioral analysis with insights derived from prior attack patterns.

Using technologies such as the Incident Graph and DIGEST (Darktrace Incident Graph Evaluation for Security Threats), activity is not analyzed in isolation. Instead, relationships between users, devices, connections, and events are mapped over time, allowing the system to reconstruct how an incident is unfolding and how similar incidents have progressed in the past.

By evaluating these patterns, Darktrace can assess the likelihood that an incident will escalate, prioritizing the activity that poses the greatest risk and surfacing the most relevant context for investigation.

This shifts security operations from simply identifying anomalies to understanding their trajectory, helping teams anticipate potential impact and respond earlier with greater precision.

Why NDR is shifting from reactive detection to proactive, AI-driven security

Traditional approaches to NDR have been built around reactively identifying threats once they become clearly visible. That model is increasingly difficult to rely on.

Attackers are no longer operating in ways that stand out. They use valid credentials, trusted tools, and low-and-slow techniques that blend into everyday activity. By the time something looks obviously malicious, the impact is often already underway.

This is the core limitation of reactive detection. It depends on recognizing something that already looks like a threat.

As a result, many of the most consequential incidents today fall into a gap.

Insider activity, compromised credentials, and novel attacks rarely trigger traditional alerts because they do not follow known patterns. On the surface, they often appear legitimate, making them difficult to distinguish from normal behavior without deeper context.

This is why we believe this Gartner recognition reflects a broader shift in NDR toward autonomous, proactive and pre‑emptive security operations.

By understanding normal behavior within an environment, it is possible to identify subtle deviations rather than waiting for confirmation of threats as they are taking place.

Darktrace’s Self-Learning AI is designed for behavioral understanding. By continuously learning each organization’s normal patterns, it can detect deviations in real time, enabling a proactive and pre-emptive model of NDR where security teams can respond to early signs of risk as they emerge, reducing the window in which attacks can develop.

In multiple cases, this behavioral approach has led to early threat detection where Darktrace identified completely unknown threats, including pre-CVE zero-day activity. By detecting subtle behavioral changes before vulnerabilities were publicly disclosed or widely understood, organizations can mitigate threats before they do damage.

This shift is subtle but important. Modern NDR solutions must shift from a system that explains what happened to one that helps prevent threats from developing in the first place, and Darktrace is proud to be at the forefront of this shift - helping organizations build and maintain a state of proactive network resilience.

Continuing to innovate at the forefront of NDR

In our view, recognition as a Leader reflects where the market is today. Continuing to innovate defines what comes next.

As businesses evolve, new technologies like AI tools and agents introduce new security risks and challenges; security teams need more than simple detection. They need a complete understanding of risk as it develops, the ability to investigate it in context, and to contain threats at machine speed.  

Darktrace / NETWORK is built to deliver across that full spectrum. Its Self-Learning AI continuously adapts to each organization’s environment, identifying subtle behavioral changes that signal emerging threats. Integrated investigation and autonomous response reduce the time between detection and action, allowing teams to move with greater speed and confidence.

This combination enables organizations to detect and contain known, unknown, and insider threats as they develop, while also strengthening resilience over time.

As a two-time Leader in the Gartner® Magic Quadrant™ for NDR and the only 2025 Gartner® Peer Insights™ Customers’ Choice, we feel Darktrace continues to evolve its platform to meet the demands of modern environments, delivering a more complete and adaptive approach to network security.

Prompt Security in Enterprise AI: Strengths, Weaknesses, and Common Approaches

prompt securityDefault blog imageDefault blog image

How enterprise AI Agents are changing the risk landscape  

Generative AI Agents are changing the way work gets done inside enterprises, and subsequently how security risks may emerge. Organizations have quickly realized that providing these agents with wider access to tooling, internal information, and granting permissions for the agent to perform autonomous actions can greatly increase the efficiency of employee workflows.

Early deployments of Generative AI systems led many organizations to scope individual components as self-contained applications: a chat interface, a model, and a prompt, with guardrails placed at the boundary. Research from Gartner has shown that while the volume and scope of Agentic AI deployments in enterprise environments is rapidly accelerating, many of the mechanisms required to manage risk, trust, and cost are still maturing.

The issue now resides on whether an agent can be influenced, misdirected, or manipulated in ways that leads to unsafe behavior across a broader system.

Why prompt security matters in enterprise AI

Prompt security matters in enterprise AI because prompts are the primary way users and systems interact with Agentic AI models, making them one of the earliest and most visible indicators of how these systems are being used and where risk may emerge.

For security teams, prompt monitoring is a logical starting point for understanding enterprise AI usage, providing insight into what types of questions are being asked and tasks are being given to AI Agents, how these systems are being guided, and whether interactions align with expected behavior. Complete prompt security takes this one step further, filtering out or blocking sensitive or dangerous content to prevent risks like prompt injection and data leakage.

However, visibility only at the prompt layer can create a false sense of security. Prompts show what was asked, but not always why it was asked, or what downstream actions were triggered by the agent across connected systems, data sources, or applications.

What prompt security reveals  

The primary function of prompt security is to minimize risks associated with generative and agentic AI use, but monitoring and analysis of prompts can also grant insight into use cases for particular agents and model. With comprehensive prompt security, security teams should be able to answer the following questions for each prompt:

  • What task was the user attempting to complete?
  • What data was included in the request, and was any of the data high-risk or confidential?
  • Was the interaction high-risk, potentially malicious, or in violation of company policy?
  • Was the prompt anomalous (in comparison to previous prompts sent to the agent / model)?

Improving visibility at this layer is a necessary first step, allowing organizations to establish a baseline for how AI systems are being used and where potential risks may exist.  

Prompt security alone does not provide a complete view of risk. Further data is needed to understand how the prompt is interpreted, how context is applied, what autonomous actions the agent takes (if any), or what downstream systems are affected. Understanding the outcome of a query is just as important for complete prompt security as understanding the input prompt itself – for example, a perfectly normal, low-risk prompt may inadvertently result in an agent taking a high-risk action.

Comprehensive AI security systems like Darktrace / SECURE AI can monitor and analyze both the prompt submitted to a Generative AI system, as well as the responses and chain-of-thought of the system, providing greater insight into the behavior of the system. Darktrace / SECURE AI builds on the core Darktrace methodology, learning the expected behaviors of your organization and identifying deviations from the expected pattern of life.

How organizations address prompt security today

As prompt-level visibility has become a focus, a range of approaches have emerged to make this activity more observable and controllable. Various monitoring and logging tools aim to capture prompt inputs to be analyzed after the fact.  

Input validation and filtering systems attempt to intervene earlier, inspecting prompts before they reach the model. These controls look for known jailbreak patterns, language indicative of adversarial attacks, or ambiguous instructions which could push the system off course.

Importantly, for a prompt security solution to be accurate and effective, prompts must be continually observed and governed, rather than treated as a point-in-time snapshot.  

Where prompt security breaks down in real environments

In more complex environments, especially those involving multiple agents or extensive tool use, AI security becomes harder to define and control.

Agent-to-Agent communications can be harder to monitor and trace as these happen without direct user interaction. Communication between agents can create routes for potential context leakage between agents, unintentional privilege escalation, or even data leakage from a higher privileged agent to a lower privileged one.

Risk is shaped not just by what is asked, but by the conditions in which that prompt operates and the actions an agent takes. Controls at the orchestration layer are starting to reflect this reality. Techniques such as context isolation, scoped memory, and role-based boundaries aim to limit how far a prompt’s influence can extend.  

Furthermore, Shadow AI usage can be difficult to monitor. AI systems that are deployed outside of formal governance structures and Generative AI systems hosted on unknown endpoints can fly under the radar and can go unseen by monitoring tools, leaving a critical opening where adversarial prompts may go undetected. Darktrace / SECURE AI features comprehensive detection of Shadow AI usage, helping organizations identify potential risk areas.

How prompt security fits in a broader AI risk model

Prompt security is an important starting point, but it is not a complete security strategy. As AI systems become more integrated into enterprise environments, the risks extend to what resources the system can access, how it interprets context, and what actions it is allowed to take across connected tools and workflows.

This creates a gap between visibility and control. Prompt security alone allows security teams to observe prompt activity but falls short of creating a clear understanding of how that activity translates into real-world impact across the organization.

Closing that gap requires a broader approach, one that connects signals across human and AI agent identities, SaaS, cloud, and endpoint environments. It means understanding not just how an AI system is being used, but how that usage interacts with the rest of the digital estate.

Prompt security, in that sense, is less of a standalone solution and more of an entry point into a larger problem: securing AI across the enterprise as a whole.
