Today’s workforce is more dispersed and mobile than ever before, with critical operations increasingly residing in a diverse patchwork of cloud services and endpoints. This architectural shift has been met by attacks that have scaled up to capitalize on insufficiently protected data and devices, emphasizing the need for enterprise security to be adaptive, autonomous, and ubiquitous.

Increasing demands placed on the SOC have stretched security teams to breaking point, and CISOs now progressively seek to streamline workflows by favoring self-learning enterprise-wide security platforms over disparate and siloed point solutions with limited visibility.

Version 5 offers a series of innovations across Darktrace’s Immune System platform, bringing critical value to security teams grappling with the new normal. This free upgrade for existing customers allows for on-demand automated investigations, supports one-click integrations with a wide range of technologies, and showcases an improved Model Editor that allows security teams to tailor Darktrace even further to their specific business risks.

Darktrace’s Immune System has been enhanced in three critical areas: in the augmentation of its core AI capabilities, in extended coverage to SaaS applications and zero-trust environments, and an open architecture which streamlines workflows across the cyber security stack.

AI augmentation

Last year saw the introduction of new technologies, services, data flows, and topologies. Static rules and signature-based defenses were unable to adapt to changing users and working practices, no matter how diligently and rapidly they were rewritten. We have seen an urgent need for augmentation, and to that end Version 5 enhances Darktrace’s self-learning capabilities across two core areas of the platform: Autonomous Response and AI Investigation.

By containing machine-speed threats like ransomware in seconds, Autonomous Response enables security teams to prioritize strategic work even as the volume and speed of attacks continues to rise. Darktrace Antigena can either take self-directed action or integrate with existing investments, informing third-party systems about in-progress cyber-attacks.

With Version 5, Antigena can now neutralize attacks in a wide variety of SaaS services like Zoom and Microsoft Teams, as well as cloud file storage applications like SharePoint and OneDrive. In cases of account takeover, Antigena can autonomously respond, protecting sensitive data in the cloud without any human intervention.

Cyber AI Analyst also now automates investigations beyond network events to SaaS applications, cloud infrastructure, and cyber-physical systems. Version 5 enables on-demand investigations into users and devices of interest, the ingestion of third-party alerts to trigger new investigations, and seamless integration with any SIEM, SOAR, or downstream ticketing system.

Customers have already found that the new capabilities in Cyber AI Analyst have added substantial value, especially in the ability to launch on-demand investigations and query SaaS data at any time.

Dynamic workforce protection

In addition to the extension of AI-enabled investigations and response, Darktrace Version 5 complements native cloud and SaaS defenses with a range of critical enhancements, including a dedicated SaaS Console, and integrations with Zoom, Okta, Microsoft Teams, Slack, Duo, and more. Equally, new ingestion capabilities for zero-trust technologies enable Darktrace to protect employees wherever they operate.

Customers can also now choose to purchase Client Sensors that extend the Immune System’s visibility of the dynamic workforce on and off the VPN. With Client Sensors, organizations can take Darktrace’s existing real-time analysis and tie it in with risky or malicious behavior that may be occurring off the VPN.

Antigena Email, the world’s first self-learning email security solution, has also been enhanced with Version 5. Not only does the technology detect the subtle deviations in threatening emails that other tools miss, but with text-based summarization, the story behind every email is automatically generated in plain English so that even a non-technical reader can fully understand why specific actions were taken.

Open architecture and interoperability

Flexibility and the ability to integrate with existing enterprise security investments lie at the core of the Darktrace Immune System, and Version 5 extends its open and extensible architecture to seamlessly integrate with your existing investments. New functionality enables customers to enhance and extend their Darktrace deployment via one-click integrations. This includes the ability to immediately extend coverage to new cloud services, and enrich the platform’s analysis with new sources of log ingestion.

Version 5 also sees the introduction of bespoke new interfaces that cover the different areas of the digital infrastructure – from the aforementioned SaaS Console to a specialized OT Engineer View. These inclusions represent an overarching design principle of unification, and the interfaces are harmonized accordingly to facilitate seamless investigations and simplified workflows.

Our customers are increasingly using the Immune System protect their business across email, SaaS, and industrial systems as well as the corporate network, and Version 5 makes it easier than ever to defend these environments.

Version 5 not only expands the Darktrace Immune System to new areas of the business, but also ensures that this expansion delivers a seamless experience for customers, regardless of where they start their journey with the platform. Delivery and expansion are entirely flexible, with the option of 100% cloud-delivered deployments, or hybrid deployments that cover on-premise and cloud environments.

Enterprise security: Innovating through times of change

As organizations accelerate digital transformation and prepare for the future of work, the ability to quickly adapt and integrate their security defenses will be more critical than ever. And with the new AI augmentation and extended coverage of Darktrace’s core self-learning technology, Version 5 ensures that customers can detect, contain, and investigate threats wherever they arise, without placing any additional burden on security teams.

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.
