NDR部門での継続した評価  

ダークトレースは2026年Gartner® Magic Quadrant™レポートのNetwork Detection and Response(NDR)部門において、2年連続でLeaderの1社に認められました

この継続的評価は、変化を続けるNDR市場における安定した実行力、適応力、成果が反映されたものと私たちは確信しています。

業界のアナリストによりNDR分野のLeaderの1社と認識されたことを大いに誇りに思う一方で、これは当社に対する評価の1部にすぎません。ダークトレースは2025年Gartner® Peer Insights™ のNDR部門において、顧客の直接のフィードバックおよび現実世界での体験に基づき、唯一Customers’ Choiceに選出されています。

私たちはこれら2つの指標の組み合わせが重要であると考えています。1つは市場がどのような評価をしたかを反映しています。もう1つは、テクノロジーが実際にどのように機能しているかを反映したものです。

ダークトレースがリーダーとして評価され続けている理由

当社が2年連続でLeaderの1社との評価を受けたことは、NDR分野での継続した実現力、絶え間ないAIイノベーション、および世界中の顧客やパートナーに対してセキュリティの成果を提供してきた実績が反映されたものであると私たちは確信しています。

私たちはまた、NDR市場におけるリーダーとの位置づけは、当社の独自で多層的なAIアプローチの証であると感じており、このアプローチのためにFast Companyの2026年度Most Innovative AI Companies(最も革新的なAI企業)リストで第7位に選ばれ、さらにCRNのAI 100において最も注目されるAIサイバーセキュリティ企業の1社と認められています。

複雑な現実世界のさまざまな環境に適応

組織が防御しているのはもはや1つのネットワーク境界だけではありません。多様なユーザー、デバイス、アプリケーションの混在、そしてハイブリッド環境間を移動するデータを保護しなければならないのです。

ダークトレースはこうした条件下においても可視性と検知能力を維持し、拡大するアクティビティをセキュリティチームが理解できるようにすることに集中してきました。

世界中の組織を柔軟にサポート

セキュリティの成果は、検知能力と同じように運用とサポートによっても左右されます。

ダークトレースは世界29か国で現地展開への投資を続けており、組織がその地域の要件、社内プロセス、チームの構成に沿った形でNDRを運用できるよう支援しています。

検知を超えてAIを応用

サイバーセキュリティにおけるAIは、多くの場合検知精度を向上させる手法として位置付けられています。しかし、より重要な技術革新はAIを意思決定や対応に生かすことです。

ダークトレースは、リアルタイムのビヘイビア分析と過去の攻撃パターンから得られた情報を組み合わせ、ライブ環境と過去のインシデントデータの両方から学習するモデルの開発を続けています。

インシデントグラフやDIGEST(Darktrace Incident Graph Evaluation for Security Threats)などの技術を利用し、アクティビティは単独で分析されることはありません。ユーザー、デバイス、接続、およびイベント間の関係が継続的にマッピングされることで、システムは過去にあった類似のインシデントの進展も含めてインシデントの進行状況を把握し、再構築することができます。

これらのパターンを評価することにより、Darktraceはインシデントがエスカレートする可能性を評価し、最もリスクの高いアクティビティを優先づけ、最も関連性の高いコンテキストを提示して調査することができます。

これによりセキュリティオペレーションは単に異常を識別することから、それらの軌跡を理解することへとシフトし、潜在的な影響を予期するとともに、より早期に、より正確に対応することが可能になります。

NDRは受け身の検知からプロアクティブなAI駆動のセキュリティへ

従来のNDRへのアプローチは脅威が明らかに確認できるようになってから受動的に識別することが中心でした。しかしこのモデルに頼ることは次第に困難になっています。

攻撃者はもはや、目立つ形で作戦を展開していません。彼らは正規の認証情報や信頼されるツールを利用し、日常の活動に紛れ込むローアンドスロー型のテクニックを駆使しています。何かが明らかに悪意のあるものに見えるとき、その影響は既に進行中であることがしばしばです。

これが受動的な検知の根本的な限界です。既に脅威と見えるものを識別することに依存しているからです。

その結果、最も重大なインシデントの多くが完全に漏れ落ちてしまいます。

内部関係者の活動、漏洩した認証情報、そして新手の攻撃は、従来のアラートをトリガーすることはめったにありません。既知のパターンに沿っていないからです。それらは表面上、正規の動作に見えることがしばしばであり、より深いコンテキスト情報がなければ通常の振る舞いと区別することは困難です。

このことが、今回のGartner社による評価がNDR全体の自律的、プロアクティブかつ先制的なセキュリティオペレーションへのシフトを反映したものと私たちが考えている理由です。

環境内での正常な振る舞いを理解することにより、脅威が発生している中で確認を待つのではなく、かすかな逸脱を識別することができるようになります。

Darktraceの自己学習型AIは行動を理解するために設計されています。それぞれの組織の通常のパターンを継続的に学習することでリアルタイムに逸脱を検知し、セキュリティチームがリスクの初期兆候に対応して攻撃が進行する時間を短縮する、プロアクティブかつ先制的なNDRモデルを実現します。

複数の事例において、このビヘイビアベースのアプローチが早期の脅威検知につながっており、DarktraceはCVE公開前のゼロデイ脅威を含む完全に未知の脅威を検知しています。脆弱性が公開され広く理解される前からわずかな挙動の変化を検知することで、組織は被害が出る前に脅威を軽減することができます。

この違いは目立ちませんが非常に重要です。現代のNDRソリューションは、何が起こったかを説明するシステムから、脅威が発生するのを未然に防ぐのを支援するシステムへとシフトしなければなりません。ダークトレースはこの変革の最前線に立ち、プロアクティブなネットワークレジリエンスの構築および維持を支援しています。

NDRの最前線でイノベーションを継続

私たちは、リーダーとしての評価は現在の市場の状況を反映したものと考えています。そして今後の状況はイノベーションの継続により決まるでしょう。

ビジネスの進化により、AIツールやエージェント等の新たなテクノロジーが新たなセキュリティリスクや課題をもたらしており、セキュリティチームは単なる検知以上のものを必要としています。リスクの進行に対する完全な理解、コンテキストを考慮して調査し、マシンスピードで脅威を封じ込める能力が必要なのです。

Darktrace / NETWORK はこれらを包括的に提供するよう設計されています。自己学習型AIは、それぞれの組織の環境に継続的に適応し、新たな脅威をの兆候であるわずかな挙動の変化を識別します。統合された調査機能と自律遮断により、検知から対応までの時間が短縮され、セキュリティチームはより迅速かつ自信を持って行動できるようになります。

この組み合わせにより、組織は既知および未知の脅威、内部関係者による脅威を発生とともに検知および封じ込めることができると同時に、全体のレジリエンスを強化していくことが可能になります。

Gartner® Magic Quadrant™のNDR部門で2度Leaderの1社と評価され、2025年Gartner® Peer Insights™において唯一のCustomers’ Choiceに選ばれたダークトレースは、現代の多様な環境の要求に応えるためにプラットフォームを進化させ続け、ネットワークセキュリティに対してより包括的かつ適応型のアプローチを提供しています。

The Problem of Re-defining Human Value in the Agentic Age

Default blog imageDefault blog image

Newsfeeds are constantly informing us about the rapid escalation of agentic AI systems. These systems move far beyond simple machine-based computations, and  the focused, defined and bounded assistance that most AI systems started out as.

The next evolution of AI will harness the agentic properties of orchestration, automation, and heightened value-chains in IT, taking on the burden of workflow management, not just workflow delivery.

In nearly all of these instances, promises are made such as ‘this will free up human time’ or ‘this will allow people to focus on higher-order strategy’. However that message is delivered, one thing is clear: in ceding the orchestration and management of work to increasingly sophisticated AI agents and agentic systems, human value will be elevated to a particular and specific layer: the ability to judge its outputs.  As AI takes on more tasks, humans should be able to focus on a higher level of governance; making sure the decisions that AI offers us are ethical, responsible and worthwhile.  

But there are two major problems with that approach.

This blog discusses the problem of how Agentic systems are re-shaping how we review information, where we fit in, and when we make decisions.  It also discusses the problem of how the increased flow of confident, generated information affects the way we make judgement.  This blog considers how human judgement needs to adapt, and how a behavioral defense approach – using techniques pioneered by Darktrace – can help us do that.

The challenge of knowing where human judgement belongs

As we confer more automated decision-making to agentic systems, it might look increasingly less like ‘granting permissions’, and more like ‘surrendering authority’.  

The judgement layer for AI-generated work is not a fixed boundary. We have become used to the idea of a ‘human in the loop’ (HITL) and, historically, relationships between humans and IT systems were reasonably clear and bounded.  Computer and software systems were programmed to carry out certain tasks or automated functions, and humans could control the gates and decision points where actions were undertaken. Even across highly complex computational workflows, human interaction was a controllable node within the process; we were able to configure and regulate. But in the agentic age, where that human interaction sits, and what it can influence shifts every time AI systems are granted autonomy.  

This leads us to the first problem: if humans are moving themselves (or are being moved) into the ‘judgement’ part of the value chain, exactly where and when do we exercise that judgement?  

Humans are no longer the sole shepherds of computer-based or software-controlled outputs.  We are at times at least one step further (and slower) behind the new agentic shepherds.  We might also be blind to what they are doing.  Not only might we be removed and blind to the actions of our AI shepherds, but with the challenge of unknown, unapproved AI systems operating beyond our control, humans might not even know that our work is being shepherded by an AI at all.  Simply put, with the advent of greater levels of autonomy and orchestration, humans are at risk of not even knowing where to apply our newly-extended powers of strategic judgement.

Shadow AI – the use of unapproved AI systems or processes – is a growing threat to the role of effective governance and oversight. Shadow AI isn't just the AI you can't see. Its the AI you already know about being used in an unapproved way. The ability to generate effective oversight of the AI systems you use (or that are used on your behalf) will be increasingly important to ensure that human judgement in the AI value chain is effective, and deliberately placed.

The problem of what makes good judgement

The second problem lies in how flawed human judgement can be.  Humans are historically, notoriously, and, sometimes dangerously, unreliable when it comes to exercising judgement.  Humans are prone to the worst kinds of bias, the seduction of malign influence, and the sometimes-overwhelming urge to succeed. AI has long had a known flaw of operating with sycophancy, providing outputs that tend to agree with or flatter the human user.  But as AI grows ever more effective, there is a risk of both hyper-enablement (where humans increasingly and knowingly enable AI despite potential harm), as well as the greater risk of suggestion. Both of these aspects could skew the newly-elevated input of human judgement.

Imagine a highly competent AI system that has just orchestrated and managed a dizzying array of processes and workflows.  The AI is designed to present the human decision-maker with recommendations; based on analysis, comparison and other programmed factors.  This is where the human judgement layer is enabled.  But what if that judgement is summarily diffused by an AI-based recommendation that emulates the decision, provides plausible but unattractive alternatives, then suggests (or, worse, directs) the human end-user to take a particular course of action.

The risk here is that you are given a recommendation, tailored to your preferences (which the AI has learned, or which you have divulged), and which appears to make perfect sense.  It appears to be a well-weighted recommendation, with sound arguments that tap into our inherent biases or inclinations so that a specific decision-path is followed. With the growth of agentic systems specifically designed to match user profiles (from Cowork agents to ‘digital twin’ models), the likelihood of agentic influence could badly skew human judgement or, at the least, devalue the proposition that humans are taking a higher-layer of strategic control over AI-based decisions.

If AI convincingly recommends something that may be problematic, it can be difficult to discern both accurate data, and the context required to make the right judgement.

Given the two problems described above, the job of exercising valuable human judgement in the agentic age can draw down to these two questions:

  • When should humans intervene in the agentic process?  
  • How can we make the best possible judgement calls?

What humans contribute that AI cannot

For all the flaws that make human judgement unreliable, people have the edge over even the most sophisticated and powerful AI systems when it comes to issues such as ethics and social context.  An AI system can, with startling granularity, rank the value of adopting a new business proposal: offering predictive metrics on costs, returns, market value, time-to-deliver operations, conformance with legal registers, etc.  But it can’t tell if the business proposal is ethically sound, or if the business venture will potentially affect groups outside of the analyzed proposal. It can’t tell you if the CEO has a ‘bad feeling’ about this effort.  It can’t tell you if this is the right thing to do.  

The ability to add social context, balance complex interpersonal dynamics, understand nuance, and to go beyond what seems economically reasonable is where human judgement can add value.  

Human judgement is difficult to encapsulate in metrics. And the way we train our development may need to adapt too. Rather than building up a gradual, experiential knowledge base, we should think about training the skill of judgement itself; especially for an agentic age.

How behavioral security strengthens AI governance

If this all feels like a vicious circle (‘I need AI help to make good judgements’ / ‘AI can twist what I need to judge’) it needn’t be. The key to this is having a defense-in-depth approach, with tools that can actually help.

This is precisely where behavioral security becomes important. The complex and nuanced way that humans exercise judgement is often rooted in our ability to recognize behavior that doesn't look right. We may not always be able to articulate it immediately, but we can often identify when an action, recommendation, or outcome feels inconsistent with the context around it. As AI systems take on more responsibility across the decision chain, preserving that ability to recognize meaningful deviations becomes increasingly important.

Darktrace’s / SECURE AI is designed to do exactly that. It applies behavioral security to AI ecosystems, helping organizations understand how people, AI tools, identities, and agents interact across the business. By learning the patterns of normal AI usage and surfacing activity that deviates from those patterns, it provides security teams with the context needed to investigate risk, understand unusual behavior, and make informed governance decisions. Rather than relying solely on predefined rules or assumptions, this behavioral understanding helps organizations distinguish between expected AI activity and behavior that warrants closer scrutiny.

This matters because we are already in an era of information overload. If humans are expected to elevate their value through strategic judgement, the ability to do this without being overwhelmed by data (good or bad) will be critical.  

We need the ability to discern when we're being misled by AI, and whether our judgement calls are being made on the basis of accurate, contextual information. Darktrace / SECURE AI provides that additional layer of defensive security for activity we cannot easily see. Whether it is suspected Shadow AI or skewed recommendations, the net result is a protected organization, where users can more effectively use AI to make positive judgements.

For those where that judgement is a critical skill (both individuals, as well as those working in security teams), improving our metacognition - the ability to understand information in a broader context - will supercharge the value of human judgement. When those judgements are grounded in context rather than assumptions we have better information to make sound decisions.

Conclusion

Human judgement is a skill that is honed over time and experience.  Darktrace’s / SECURE AI employs the same principles, but at machine-speed. Rather than influencing or directing, Darktrace / SECURE AI offers AI-enabled assurance; providing human-based judgement with the right context to make a balanced decision.  

What we judge can be valued by the legitimacy of its outputs. For AI, those outputs are valued on the speed and accuracy of the information provided.  Increasingly for humans, the value of our outputs will be based on the validity of our judgement, and how we justify our decisions in ways that engineer confidence.  

Humans often know more than we can express, while AI is prone to expressing more than it truly understands. Humans can bridge the context AI often fails to appreciate. When that judgement is supported by relevant, impartial AI systems, this is the future space where good AI governance will be exercised.

Darktrace Advances Incident Investigation and AI-Agent Security with OpenAI Daybreak Models

Default blog imageDefault blog image

Earlier this year, Darktrace joined OpenAI’s Daybreak Defense Network to explore how their cyber capabilities can be integrated within Darktrace products and services to transform how security teams move from signal to action.

At the heart of this work is Darktrace's behavioral understanding of customer environments and identification of complex security incidents, combined with OpenAI models that can add context to help explain why an incident matters and its potential impact on the business. By bringing these capabilities into defensive workflows security teams already use, the goal is to give defenders not just greater visibility, but the context and guidance they need to act with confidence.

Since joining the program, we've been working with OpenAI to explore how these capabilities can address specific security challenges for defenders.

The problem we're solving

Attackers continue to change how they operate, including by using AI to increase the speed and scale of some techniques. Security teams are already managing a large volume of alerts, and the question isn't just what's happening, but how it could affect the organization. Even when an incident is fully investigated and correlated, technical severity alone doesn't tell a security team how much it actually matters to the business. That same challenge extends to internal AI adoption. As organizations adopt more AI systems and agents, security teams need visibility into their behavior, access and activity, along with the broader business context needed to identify and investigate potential risk.

Darktrace's Adaptive AI™ builds a detailed, organization-specific picture of what's normal for each environment, and uses that picture to investigate threats and identify complex security activity across domains. OpenAI's models can build on Darktrace's correlated, technically prioritized incidents by adding context that can help defenders understand what may be at stake.

What we're building

Our work is focused on two areas: supporting security investigation and response, and helping defenders identify risky behavior across enterprise AI systems and agents.

The first aligns Darktrace's behavioral understanding with OpenAI models to support  security investigation and prioritization. Darktrace's Adaptive AI continuously learns the unique patterns of normal behavior within each customer it protects, creating a deep, organization-specific understanding of its digital estate. When unusual activity emerges, OpenAI's models can draw on that context to help analysts investigate the incident, understand its significance and assess potential business consequences — reducing the need to manually assemble context from fragmented signals.

Second, we are exploring how these capabilities can support AI-agent and runtime security through Darktrace / SECURE AI™. OpenAI’s Daybreak models can build on the detections and visibility Darktrace / SECURE AI provides, connecting signals across a customer's environment and help defenders identify potentially risky behavior involving AI systems and agents. Activity that might appear isolated can instead be connected with related signals, helping defenders investigate the broader context and determine appropriate remediation.

Darktrace brings deep cybersecurity expertise, an evolving understanding of each customer's environment, and AI-driven identification of threats across the digital estate. Through the Daybreak Defense Network, Darktrace is exploring how OpenAI models can augment those capabilities in defensive security workflows — supporting incident investigation and response and improving visibility into AI-agent and runtime risk.

These capabilities are still in development, and we're excited to continue building on this work.
