The need for scalable cloud-native security

The cybersecurity landscape is undergoing a rapid transformation driven by the accelerated adoption of cloud computing, compelling organizations to reevaluate their security strategies. According to Forrester’s Infrastructure Cloud Survey, 2023, cloud decision-makers who are moving to a cloud computing infrastructure estimated they have already moved 39% of their application portfolio to the cloud and intend to move another 53% in the next two years [1].

This explosive growth underscores not only the increased dependency on cloud services, but also the evolving sophistication of cyber threats targeting these platforms, and the critical need for dedicated security measures tailored to cloud infrastructures — thereby making cloud security a pivotal focus for Security Operations Center (SOC) teams.

As organizations increasingly migrate to cloud environments and their reliance on cloud infrastructures deepens, they encounter new security challenges that require reevaluating their security strategies. Traditional measures like Network Detection and Response (NDR) are being reassessed in favor of more dynamic, scalable cloud-native solutions.

However, can we truly say that cloud detection and response (CDR) is fundamentally different? Or is it simply an evolution of NDR tailored for the cloud?

Cloud Detection and Response (CDR) vs Network Detection and Response (NDR)

Cloud Detection and Response (CDR) has emerged as a pivotal technology in the race against threat actors targeting cloud assets. CDR is typically centered around the same foundational principles as NDR. As such, NDR providers are well placed to provide these capabilities within dynamic cloud environments – particularly those providers that are built upon the foundation of understanding your business, its digital footprint, and leveraging that understanding to detect subtle deviations and highlighting anomalies as opposed to pre training or relying on rules and signatures.

However, there are unique challenges within cloud environments that require a wider, richer, context-aware approach.

Why SOC Teams Care

Widespread UseThe shift towards cloud services is no longer a trend but a standard practice across industries. Organizations increasingly rely on cloud infrastructures for essential operations across IaaS, PaaS, and SaaS platforms. According to Gartner, worldwide end-user spending on public cloud services is forecast to grow 20.4% to total $678.8 billion in 2024, up from $563.6 billion in 2023 [2]. This widespread adoption necessitates a security approach that can operate seamlessly across varied cloud environments, addressing both the scalability and the agility that these platforms offer.

Sophisticated AttacksCyber threats have evolved in sophistication, specifically targeting cloud platforms due to their growing prevalence. Attackers exploit the dynamic nature of cloud services, where traditional security measures often fall short. The cloud has emerged as a major target for threat actors who want to control access to, manipulate, and steal that data. This makes cloud resources a bigger target than ever for attackers. According to the IBM Cost of a Data Breach 2023 report, 82% of breaches involved data stored in the cloud [3]. Examples include data breaches initiated through misconfigured storage instances or through the exploitation of incomplete data deletion processes, highlighting the need for cloud-specific security responses.

Dynamic EnvironmentsCloud environments are inherently dynamic, characterized by the rapid provisioning and de-provisioning of resources, this fluidity presents a significant challenge for maintaining continuous security oversight, organizations need to be able to see what individual assets in the cloud look like at any given moment, who or what can access those, but also to be able to detect and respond to changes in real time. Unlike traditional infrastructure, detection and response in the cloud is challenging because of the ephemeral nature of some cloud assets and the velocity and volume of new app deployment – traditional signature-based detections will often struggle to work with such data.

What SOC Teams Need

Centralized VisibilityEffective security management requires a comprehensive, unified view spanning all operational environments including multi-cloud platforms and on-premises datacenters. Furthermore, in today's complex IT landscape, where organizations operate across both on-premises and various cloud environments, the need for centralized visibility becomes paramount. This comprehensive oversight is crucial for detecting anomalies and potential threats in real time, allowing SOC teams to manage security from a single source of truth, despite the dispersed nature of cloud assets and the heterogeneity of on-premises resources. By integrating these views, organizations can ensure a seamless security posture that encompasses all operational environments, enhancing their ability to respond swiftly to incidents and reduce security gaps.

AutomationGiven the vast scale and complexity of cloud operations, automation in detection and response processes is indispensable. Automated security solutions can instantly respond to threats, or adjust permissions across the cloud, enhancing both the efficiency and effectiveness of security measures.

Containment and RemediationThe capability for swift containment and remediation of security incidents is vital to minimize their impact on business operations. Automated response mechanisms that can isolate affected systems, revoke access, or reroute traffic until the threat is neutralized are essential components of modern CDR solutions.

Unpacking the Essentials: What Sets CDR Apart from NDR

While CDR and NDR share similar goals of threat mitigation, the context within cloud environments brings additional complexities:

Who: The identification of user roles and access patterns in cloud environments is crucial for detecting insider threats or compromised accounts. For example, an account behaving irregularly or accessing unusual data points may indicate a security breach.

What: Understanding what resources are deployed in the cloud (such as VMs, containers, and serverless functions) and the types of data they handle helps prioritize security efforts. Protecting data with varying sensitivity levels requires different security protocols.

Where: The geographic distribution of cloud datacenters affects regulatory compliance and data sovereignty. Security measures must consider these factors to ensure that data storage and processing comply with local laws and regulations.

How: Monitoring the configuration and usage of cloud services helps in identifying misconfigurations and anomalous usage patterns, which are common vectors for attacks. Tools that can automatically scan and rectify configurations in real time are particularly valuable in maintaining cloud security.

Key takeaways and benefits of CDR

As cloud adoption continues to surge, the strategic importance of CDR becomes increasingly evident. However, NDR vendors are well-positioned to provide these capabilities, especially those who deeply understand customer environments by learning the pattern of life of resources rather than relying on static rules and signatures.

Cloud environments, at their core, are still comprised of networks for communication. Interactions between cloud resources need to be monitored in real time, and access to these resources needs to be tracked and managed. As the cloud changes dynamically, the understanding and visualization of what is deployed and where needs to be updated quickly. Above all effective and proportional cloud-native response needs to be provided to mitigate threats and avoid business disruption.

Moreover, the ideal solutions will not only monitor network interactions but also bring in cloud contextual awareness. By combining these insights, SOC teams can gain a deeper understanding of permissions, assess risk vulnerabilities, and integrate all these elements into a single, cohesive platform. Importantly, SOC teams need to go beyond detection and response to actively mitigate potential misconfigurations and stay preventative. After all, proactive security is much better than reactive. By leveraging such comprehensive solutions, SOC teams can better equip themselves to tackle the modern cybersecurity landscape, ensuring robust, responsive, and adaptable defenses.

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.
