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.

Why attack-centric approaches to email security can’t cope with modern threats

Default blog imageDefault blog image

What’s the problem with an attack-centric mindset?

For decades, traditional email security strategies have been built around an attack-centric mindset. Secure Email Gateways (SEGs) and other legacy solutions operate on the principle of identifying and blocking known threats. These systems rely heavily on predefined threat intelligence – blacklists, malware signatures, and reputation-based analysis – to filter out malicious content before it reaches the inbox.

While this approach was sufficient when email threats were relatively static and signature-based, it’s increasingly ineffective against the sophistication of modern attacks. Techniques like spear phishing, business email compromise (BEC), and supply chain attacks often bypass traditional SEG defenses because they lack obvious malicious indicators. Instead, they leverage social engineering, look-alike domains, and finely tuned spoofing tactics that are designed to evade detection.

The challenge extends beyond just legacy SEGs. Many modern email security providers have inherited the same attack-centric principles, even if they've reimagined the technology stack. While some vendors have shifted to API-based deployments and incorporated AI to automate pattern recognition, the underlying approach remains the same: hunting for threats based on known indicators. This methodology, though it’s undergone modernization using AI, still leaves gaps when it comes to novel, hyper-targeted threats that manipulate user behavior rather than deploy predictable malicious signatures. Attack-centric security will always remain one step behind the attacker.

By the way, native email security already covers the basics

One of the most overlooked realities in email security is that native solutions like Microsoft 365’s built-in security already handle much of the foundational work of attack-centric protection. Through advanced threat intelligence, anti-phishing measures, and malware detection, Microsoft 365 actively scans incoming emails for known threats, using global telemetry to identify patterns and block suspicious content before it even reaches the user’s inbox.

This means that for many organizations, a baseline level of protection against more obvious, signature-based attacks is already in place – but many are still disabling these protections in favour of another attack-centric solution. By layering another attack-centric solution on top, they are effectively duplicating efforts without enhancing their security posture. This overlap can lead to unnecessary complexity, higher costs, and a false sense of enhanced protection when in reality, it’s more of the same.

Rather than duplicating attack-centric protections, the real opportunity lies in addressing the gaps that remain: the threats that are specifically crafted to evade traditional detection methods. This is where a business-centric approach becomes indispensable, complementing the foundational security that’s already built into your infrastructure.

Introducing… the business-centric approach

To effectively defend against advanced threats, organizations need to adopt a business-centric approach to email security. Unlike attack-centric models that hunt for known threats, business-centric security focuses on understanding the typical behaviors, relationships, and communication patterns within your organization. Rather than solely reacting to threats as they are identified, this model continuously learns what “normal” looks like for each user and each inbox.

By establishing a baseline of expected behaviors, business-centric solutions can rapidly detect anomalies that suggest compromise, such as sudden changes in sending patterns, unusual login locations, or subtle shifts in communication tone. This proactive detection method is especially powerful against spear phishing, business email compromise (BEC), and supply chain attacks that are engineered to bypass static defenses. This approach also scales with your organization, learning and adapting as new users are onboarded, communication patterns evolve, and external partners are added.

In an era where AI-driven threats are becoming the norm, having email security that knows your users and inboxes better than the attacker does is a critical advantage.

Why native + business-centric email security is the winning formula

By pairing native security with a business-centric model, organizations can cover the full spectrum of threats – from signature-based malware to sophisticated, socially engineered attacks. Microsoft 365’s in-built security manages the foundational risks, while business-centric defense identifies subtle anomalies and targeted threats that legacy approaches miss.

Layering Darktrace on top of your native Microsoft security eliminates duplicate capabilities, costs and workflows without reducing functionality

Rather than layering redundant attack-centric solutions on top of existing protections, the future of email security lies in leveraging what’s already in place and building on it with smarter, behavior-based detection. The Swiss Cheese Model is a useful one to refer to here: by acknowledging that no single defense can offer complete protection, layering defenses that plug each other’s gaps – like slices of Swiss cheese – becomes critical.

This combination also allows security teams to focus their efforts more effectively. With native solutions catching broad-based, known threats, the business-centric layer can prioritize real anomalies, minimizing false positives and accelerating response times. Organizations benefit from reduced overlap, streamlined costs, and a stronger overall security posture.
