What is cloud migration?

Cloud migration, in its simplest form, refers to the process of moving digital assets, such as data, applications, and IT resources, from on-premises infrastructure or legacy systems to cloud computing environments. There are various flavours of migration and utilization, but according to a survey conducted by IBM, one of the most common is the 'Hybrid' approach, with around 77% of businesses adopting a hybrid cloud approach.

There are three key components of a hybrid cloud migration model:

  1. On-Premises (On-Prem): Physical location with some amount of hardware and networking, traditionally a data centre.
  2. Public Cloud: Third-party providers like AWS, Azure, and Google, who offer multiple services such as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS).
  3. Private Cloud: A cloud computing environment where resources are isolated for one customer.

Why does cloud migration matter for enterprises?

Cloud adoption provides many benefits to businesses, including:

  1. Scalability: Cloud environments allow enterprises to scale resources up or down based on demand, enabling them to quickly adapt to changing business requirements.
  2. Flexibility and Agility: Cloud platforms provide greater flexibility and agility, enabling enterprises to innovate and deploy new services more rapidly compared to traditional on-premises infrastructure.
  3. Cost Efficiency: Pay-as-you-go model, allowing enterprises to reduce capital expenditures on hardware and infrastructure.
  4. Enhanced Security: Cloud service providers invest heavily in security measures to protect data and infrastructure, offering advanced security features and compliance certifications.

The combination of these benefits provides significant potential for businesses to innovate and move quickly, ultimately allowing them to be flexible and adapt to changing market conditions, customer demands, and technological advancements with greater agility and efficiency.

Cloud migration strategy

There are multiple migration strategies a business can adopt, including:

  1. Rehosting (Lift-and-shift): Quickly completed but may lead to increased costs for running workloads.
  2. Refactoring (Cloud Native): Designed specifically for the cloud but requires a steep learning curve and staff training on new processes.
  3. Hybrid Cloud: Mix of on-premises and public cloud use, offering flexibility and scalability while keeping data secure on-premises. This can introduce complexities in setup and management overhead and requires ensuring security and compliance in both environments.

It is important to note that each strategy has its trade-offs and there is no single gold standard for a one size fits all cloud migration strategy. Different businesses will prioritize and leverage different benefits, for instance while some might prefer a rehosting strategy as it gets them migrated the fastest, it typically ends up also being the most costly strategy as “lift-and-shift” doesn’t take advantage of many key benefits that the cloud has to offer. Conversely, refactoring is a strategy optimized at making the most of the benefits that cloud providers have to offer, however the process of redesigning applications requires cloud expertise and based on the scale of applications that are required to be refactored this strategy might not be the quickest when it comes to moving applications from being hosted on premise to in the cloud.  

Phases of a cloud migration

At the highest level, there are four main steps in a successful migration:

  1. Discover: Identify and categorize IT assets, applications, and critical dependencies.
  2. Plan: Develop a detailed migration plan, including timelines, resource allocation, and risk management strategies.
  3. Migrate: Execute the migration plan, minimizing disruption to business operations.
  4. Optimize: Continuously optimize the cloud environment using automation, performance monitoring, and cost management tools to improve efficiency, performance, and scalability.

While it is natural to race towards the end goals of a cloud migration, most successful cloud migration strategies allocate the appropriate timelines to each phase.  

The “Discover” phase specifically is where most businesses can set themselves up for success. Having a complete understanding of assets, applications, services, and dependencies needed to migrate however is much easier said than done. Given the pace of change and how laborious of a task inventorying everything can be to manage and maintain, most mistakes at this stage will propagate and amplify through the migration journey.  

Risks and challenges of cloud migration

Though cloud migration offers a wealth of benefits, it also introduces new risks that need to be accounted for and managed effectively. Security should be considered a fundamental part of the process, not an additional measure that can be ‘bolted’ on at the end.

Let’s consider the most popular migration strategy, using a ‘Hybrid Cloud’. A recent report by the industry analyst group Forrester cited that Cloud Security Posture Management (CSPM) tools are just one facet of security, stating:

"No matter how good it is, using a CSPM solution alone will not provide you with full visibility, detection, and effective remediation capabilities for all threats. Your adversaries are also targeting operating systems, existing on-prem network infrastructure, and applications in their quest to steal valuable data".

Unpacking some of the risks here, it’s clear they fall into a range of categories, including:

  1. Security Concerns: Ensuring security across both on-premises and cloud environments, addressing potential misconfigurations and vulnerabilities.
  2. Contextual Understanding: Effective security requires a deep understanding of the organization's business processes and the context in which data and applications operate.
  3. Threat Detection and Response: Identifying and responding to threats in real-time requires advanced capabilities such as AI and anomaly detection.
  4. Platform Approach: Deploying integrated security solutions that provide end-to-end visibility, centralized management, and automated responses across hybrid infrastructure.

Since the cloud doesn’t operate in a vacuum, businesses will always have a myriad of 3rd party applications, users, endpoints, external services, and partners connecting and interacting with their cloud environments. From this perspective, being able to correlate and understand behaviors and activity both within the cloud and its surroundings becomes imperative.

It then follows that context from a business wide perspective is necessary. This has two distinct implications, the first is application or workload specific context (i.e. where do the assets, services, and functions alerted on reside within the cloud application) and the second is business wide context. Given the volume of alerts that security practitioners need to manage, findings that lack the appropriate context to fully understand and resolve the issue create additional strain on teams that are already managing a difficult challenge.  

Conclusion

With that in mind, Darktrace’s approach to security, with its existing and new advances in Cloud Detection and Response capabilities, anomaly detection across SaaS applications, and native ability to leverage many AI techniques to understand the business context within your dynamic cloud environment and on-premises infrastructure. It provides you with the integrated building blocks to provide the ‘360’ degree view required to detect and respond to threats before, during, and long after your enterprise migrates to the cloud.

Bringing Together SOC and IR teams with Automated Threat Investigations for the Hybrid World

Default blog imageDefault blog image

The investigation gap: Why incident response is slow, fragmented and reactive

Modern investigations often fall apart the moment analysts move beyond an initial alert. Whether detections originate in cloud or on-prem environments, SOC and Incident Response (IR) teams are frequently hindered by fragmented tools and data sources, closed ecosystems, and slow, manual evidence collection just to access the forensic context they need. SOC analysts receive alerts without the depth required to confidently confirm or dismiss a threat, while IR teams struggle with inconsistent visibility across cloud, on‑premises, and contained endpoints, creating delays, blind spots, and incomplete attack timelines.

This gap between SOC and Digital Forensics and Incident Response (DFIR) slows response and forces teams into reactive and inefficient investigation patterns. Security teams struggle to collect high‑fidelity forensic data during active incidents, particularly from cloud workloads, on‑prem systems, and XDR‑contained endpoints where traditional tools cannot operate without deploying new agents or disrupting containment. The result is a fragmented response process where investigations slow down, context gets lost, and critical attacker activity can slip through the cracks.

What’s new at Darktrace

Helping teams move from detection to root cause faster, more efficiently, and with greater confidence

The latest update to Darktrace / Forensic Acquisition & Investigation eliminates the traditional handoff between the SOC and IR teams, enabling analysts to seamlessly pivot from alert into forensic investigation. It also brings on-demand and automated data capture through Darktrace / ENDPOINT as well as third-party detection platforms, where investigators can safely collect critical forensic data from network contained endpoints, preserving containment while accelerating investigation and response.  

Together, this solidifies / Forensic Acquisition & Investigation as an investigation-first platform beyond the cloud, fit for any organization that has adopted a multi-technology infrastructure. In practice, when these various detection sources and host‑level forensics are combined, investigations move from limited insight to complete understanding quickly, giving security teams the clarity and deep context required to drive confident remediation and response based on the exact tactics, techniques and procedures employed.

Integrated forensic context inside every incident workflow

SOC analysts now have seamless access to forensic evidence at the exact moment they need it. There is a new dedicated Forensics tab inside Cyber AI Analyst™ incidents, allowing users to move instantly from detection to rich forensic context in a single click, without the need to export data or get other teams involved.

For investigations that previously required multiple tools, credentials, or intervention by a dedicated team, this change represents a shift toward truly embedded incident‑driven forensics – accelerating both decision‑making and response quality at the point of detection.

Figure 1: The forensic investigation associated with the Cyber AI Analyst™ incident appears in a dedicated ‘Forensics’ tab, with the ability to pivot into the / Forensic Acquisition & Investigation UI for full context and deep analysis workflows.

Reliable automated and manual hybrid evidence capture across any environment

Across cloud, on‑premises, and hybrid environments, analysts can now automate or request on‑demand forensic evidence collection the moment a threat is detected via Darktrace / ENDPOINT. This allows investigators to quickly capture high-fidelity forensic data from endpoints already under protection, accelerating investigations without additional tooling or disrupting systems. Especially in larger environments where the ability to scale is critical, automated data capture across hybrid environments significantly reduces response time and enables consistent, repeatable investigations.

Unlike EDR‑only solutions, which capture only a narrow slice of activity, these workflows provide high‑quality, cross‑environment forensic depth, even on third‑party XDR‑contained devices that many vendor ecosystems cannot reach.

The result is a single, unified process for capturing the forensic context analysts need no matter where the threat originates, even in third-party vendor protected areas.

Figure 3: A Linux device that has the Darktrace / ENDPOINT agent installed has been acquired and processed by / Forensic Acquisition & Investigation

Investigation‑first design flexible for hybrid organizations

Luckily, taking advantage of automated forensic data capture of non-cloud assets won’t be subject to those who purely use Darktrace / ENDPOINT. This functionality is also available where CrowdStrike, Microsoft Defender for Endpoint, or SentinelOne agents are deployed.  In the case of CrowdStrike, Darktrace / Forensic Acquisition & Investigation can also perform a triage capture of a device that has been contained using CrowdStrike’s network containment capability. What’s critical here is the fact that investigators can safely acquire additional forensic evidence without breaking or altering containment. That massively improves investigation and response time without adding more risk factors.

Figure 5: Successful triage capture of contained endpoint ‘cado.xdr.test2’ using / Forensic Acquisition & Investigation

The benefits of extending forensics to on‑premises and endpoint environments

Despite Darktrace / Forensic Acquisition & Investigation originating as a cloud‑first solution, the challenges of incident response are not limited to the cloud. Many investigations span on‑premises servers, unmanaged endpoints, legacy systems, or devices locked inside third‑party ecosystems.  

By extending automated investigation capabilities into on‑premises environments and endpoints, Darktrace delivers several critical benefits:

  • Unified investigations across hybrid infrastructure and a heterogeneous security stack
  • Consistent forensic depth regardless of asset type
  • Faster and more accurate root-cause analysis
  • Stronger incident response readiness

Figure 6: Unified alerts from cloud and on-prem environments, grouped into incident-centric investigations with forensic depth

Simplifying deep investigations across hybrid environments

These enhancements move Darktrace / Forensic Acquisition & Investigation closer to a vision out of reach for most security teams: seamless, integrated, high‑fidelity forensics across cloud, on‑prem, and endpoint environments where other solutions usually stop at detection. Automated forensics as a whole is fueling faster outcomes with complete clarity throughout the end-to-end investigation process, which now takes teams from alert to understanding in minutes compared to days or even weeks. All without added agents, disruptions, or specialized teams. The result is an incident response lifecycle that finally matches the reality of modern infrastructure.

How to Secure AI and Find the Gaps in Your Security Operations

secuing AI testing gaps security operationsDefault blog imageDefault blog image

What “securing AI” actually means (and doesn’t)

Security teams are under growing pressure to “secure AI” at the same pace which businesses are adopting it. But in many organizations, adoption is outpacing the ability to govern, monitor, and control it. When that gap widens, decision-making shifts from deliberate design to immediate coverage. The priority becomes getting something in place, whether that’s a point solution, a governance layer, or an extension of an existing platform, rather than ensuring those choices work together.

At the same time, AI governance is lagging adoption. 37% of organizations still lack AI adoption policies, shadow AI usage across SaaS has surged, and there are notable spikes in anomalous data uploads to generative AI services.  

First and foremost, it’s important to recognize the dual nature of AI risk. Much of the industry has focused on how attackers will use AI to move faster, scale campaigns, and evade detection. But what’s becoming just as significant is the risk introduced by AI inside the organization itself. Enterprises are rapidly embedding AI into workflows, SaaS platforms, and decision-making processes, creating new pathways for data exposure, privilege misuse, and unintended access across an already interconnected environment.

Because the introduction of complex AI systems into modern, hybrid environments is reshaping attacker behavior and exposing gaps between security functions, the challenge is no longer just having the right capabilities in place but effectively coordinating prevention, detection, investigation, response, and remediation together. As threats accelerate and systems become more interconnected, security depends on coordinated execution, not isolated tools, which is why lifecycle-based approaches to governance, visibility, behavioral oversight, and real-time control are gaining traction.

From cloud consolidation to AI systems what we can learn

We have seen a version of AI adoption before in cloud security. In the early days, tooling fragmented into posture, workload/runtime, identity, data, and more. Gradually, cloud security collapsed into broader cloud platforms. The lesson was clear: posture without runtime misses active threats; runtime without posture ignores root causes. Strong programs ran both in parallel and stitched the findings together in operations.  

Today’s AI wave stretches that lesson across every domain. Adversaries are compressing “time‑to‑tooling” using LLM‑assisted development (“vibecoding”) and recycling public PoCs at unprecedented speed. That makes it difficult to secure through siloed controls, because the risk is not confined to one layer. It emerges through interactions across layers.

Keep in mind, most modern attacks don’t succeed by defeating a single control. They succeed by moving through the gaps between systems faster than teams can connect what they are seeing. Recent exploitation waves like React2Shell show how quickly opportunistic actors operationalize fresh disclosures and chain misconfigurations to monetize at scale.

In the React2Shell window, defenders observed rapid, opportunistic exploitation and iterative payload diversity across a broad infrastructure footprint, strains that outpace signature‑first thinking.  

You can stay up to date on attacker behavior by signing up for our newsletter where Darktrace’s threat research team and analyst community regularly dive deep into threat finds.

Ultimately, speed met scale in the cloud era; AI adds interconnectedness and orchestration. Simple questions — What happened? Who did it? Why? How? Where else? — now cut across identities, SaaS agents, model/service endpoints, data egress, and automated actions. The longer it takes to answer, the worse the blast radius becomes.

The case for a platform approach in the age of AI

Think of security fusion as the connective tissue that lets you prevent, detect, investigate, and remediate in parallel, not in sequence. In practice, that looks like:

  1. Unified telemetry with behavioral context across identities, SaaS, cloud, network, endpoints, and email—so an anomalous action in one plane automatically informs expectations in others. (Inside‑the‑SOC investigations show this pays off when attacks hop fast between domains.)  
  1. Pre‑CVE and “in‑the‑wild” awareness feeding controls before signatures—reducing dwell time in fast exploitation windows.  
  1. Automated, bounded response that can contain likely‑malicious actions at machine speed without breaking workflows—buying analysts time to investigate with full context. (Rapid CVE coverage and exploit‑wave posts illustrate how critical those first minutes are.)  
  1. Investigation workflows that assume AI is in the loop—for both defenders and attackers. As adversaries adopt “agentic” patterns, investigations need graph‑aware, sequence‑aware reasoning to prioritize what matters early.

This isn’t theoretical. It’s reflected in the Darktrace posts that consistently draw readership: timely threat intel with proprietary visibility and executive frameworks that transform field findings into operating guidance.  

The five questions that matter (and the one that matters more)

When alerted to malicious or risky AI use, you’ll ask:

  1. What happened?
  1. Who did it?
  1. Why did they do it?
  1. How did they do it?
  1. Where else can this happen?

The sixth, more important question is: How much worse does it get while you answer the first five? The answer depends on whether your controls operate in sequence (slow) or in fused parallel (fast).

What to watch next: How the AI security market will likely evolve

Security markets tend to follow a familiar pattern. New technologies drive an initial wave of specialized tools (posture, governance, observability) each focused on a specific part of the problem. Over time, those capabilities consolidate as organizations realize the new challenge is coordination.

AI is accelerating the shift of focus to coordination because AI-powered attackers can move faster and operate across more systems at once. Recent exploitation waves show exactly this. Adversaries can operationalize new techniques and move across domains, turning small gaps into full attack paths.

Anticipate a continued move toward more integrated security models because fragmented approaches can’t keep up with the speed and interconnected nature of modern attacks.

Building the Groundwork for Secure AI: How to Test Your Stack’s True Maturity

AI doesn’t create new surfaces as much as it exposes the fragility of the seams that already exist.  

Darktrace’s own public investigations consistently show that modern attacks, from LinkedIn‑originated phishing that pivots into corporate SaaS to multi‑stage exploitation waves like BeyondTrust CVE‑2026‑1731 and React2Shell, succeed not because a single control failed, but because no control saw the whole sequence, or no system was able to respond at the speed of escalation.  

Before thinking about “AI security,” customers should ensure they’ve built a security foundation where visibility, signals, and responses can pass cleanly between domains. That requires pressure‑testing the seams.

Below are the key integration questions and stack‑maturity tests every organization should run.

1. Do your controls see the same event the same way?

Integration questions

  • When an identity behaves strangely (impossible travel, atypical OAuth grants), does that signal automatically inform your email, SaaS, cloud, and endpoint tools?
  • Do your tools normalize events in a way that lets you correlate identity → app → data → network without human stitching?

Why it matters

Darktrace’s public SOC investigations repeatedly show attackers starting in an unmonitored domain, then pivoting into monitored ones, such as phishing on LinkedIn that bypassed email controls but later appeared as anomalous SaaS behavior.

If tools can’t share or interpret each other's context, AI‑era attacks will outrun every control.

Tests you can run

  1. Shadow Identity Test
  • Create a temporary identity with no history.
  • Perform a small but unusual action: unusual browser, untrusted IP, odd OAuth request.
  • Expected maturity signal: other tools (email/SaaS/network) should immediately score the identity as high‑risk.
  1. Context Propagation Test
  • Trigger an alert in one system (e.g., endpoint anomaly) and check if other systems automatically adjust thresholds or sensitivity.
  • Low maturity signal: nothing changes unless an analyst manually intervenes.

2. Does detection trigger coordinated action, or does everything act alone?

Integration questions

  • When one system blocks or contains something, do other systems automatically tighten, isolate, or rate‑limit?
  • Does your stack support bounded autonomy — automated micro‑containment without broad business disruption?

Why it matters

In public cases like BeyondTrust CVE‑2026‑1731 exploitation, Darktrace observed rapid C2 beaconing, unusual downloads, and tunneling attempts across multiple systems. Containment windows were measured in minutes, not hours.  

Tests you can run

  1. Chain Reaction Test
  • Simulate a primitive threat (e.g., access from TOR exit node).
  • Your identity provider should challenge → email should tighten → SaaS tokens should re‑authenticate.
  • Weak seam indicator: only one tool reacts.
  1. Autonomous Boundary Test
  • Induce a low‑grade anomaly (credential spray simulation).
  • Evaluate whether automated containment rules activate without breaking legitimate workflows.

3. Can your team investigate a cross‑domain incident without swivel‑chairing?

Integration questions

  • Can analysts pivot from identity → SaaS → cloud → endpoint in one narrative, not five consoles?
  • Does your investigation tooling use graphs or sequence-based reasoning, or is it list‑based?

Why it matters

Darktrace’s Cyber AI Analyst and DIGEST research highlights why investigations must interpret structure and progression, not just standalone alerts. Attackers now move between systems faster than human triage cycles.  

Tests you can run

  1. One‑Hour Timeline Build Test
  • Pick any detection.
  • Give an analyst one hour to produce a full sequence: entry → privilege → movement → egress.
  • Weak seam indicator: they spend >50% of the hour stitching exports.
  1. Multi‑Hop Replay Test
  • Simulate an incident that crosses domains (phish → SaaS token → data access).
  • Evaluate whether the investigative platform auto‑reconstructs the chain.

4. Do you detect intent or only outcomes?

Integration questions

  • Can your stack detect the setup behaviors before an attack becomes irreversible?
  • Are you catching pre‑CVE anomalies or post‑compromise symptoms?

Why it matters

Darktrace publicly documents multiple examples of pre‑CVE detection, where anomalous behavior was flagged days before vulnerability disclosure. AI‑assisted attackers will hide behind benign‑looking flows until the very last moment.

Tests you can run

  1. Intent‑Before‑Impact Test
  • Simulate reconnaissance-like behavior (DNS anomalies, odd browsing to unknown SaaS, atypical file listing).
  • Mature systems will flag intent even without an exploit.
  1. CVE‑Window Test
  • During a real CVE patch cycle, measure detection lag vs. public PoC release.
  • Weak seam indicator: your detection rises only after mass exploitation begins.

5. Are response and remediation two separate universes?

Integration questions

  • When you contain something, does that trigger root-cause remediation workflows in identity, cloud config, or SaaS posture?
  • Does fixing a misconfiguration automatically update correlated controls?

Why it matters

Darktrace’s cloud investigations (e.g., cloud compromise analysis) emphasize that remediation must close both runtime and posture gaps in parallel.

Tests you can run

  1. Closed‑Loop Remediation Test
  • Introduce a small misconfiguration (over‑permissioned identity).
  • Trigger an anomaly.
  • Mature stacks will: detect → contain → recommend or automate posture repair.
  1. Drift‑Regression Test
  • After remediation, intentionally re‑introduce drift.
  • The system should immediately recognize deviation from known‑good baseline.

6. Do SaaS, cloud, email, and identity all agree on “normal”?

Integration questions

  • Is “normal behavior” defined in one place or many?
  • Do baselines update globally or per-tool?

Why it matters

Attackers (including AI‑assisted ones) increasingly exploit misaligned baselines, behaving “normal” to one system and anomalous to another.

Tests you can run

  1. Baseline Drift Test
  • Change the behavior of a service account for 24 hours.
  • Mature platforms will flag the deviation early and propagate updated expectations.
  1. Cross‑Domain Baseline Consistency Test
  • Compare identity’s risk score vs. cloud vs. SaaS.
  • Weak seam indicator: risk scores don’t align.

Final takeaway

Security teams should ask be focused on how their stack operates as one system before AI amplifies pressure on every seam.

Only once an organization can reliably detect, correlate, and respond across domains can it safely begin to secure AI models, agents, and workflows.
