Every new platform, cloud migration or process change your business introduces creates additional points where data can be exposed. If your organisation is in the middle of a digital transformation, cybersecurity belongs in the conversation from day one.
Mid-market growth teams face a particular challenge. You are moving fast, connecting more tools and onboarding more users, often without a dedicated security function keeping pace. This article explains where the most common cybersecurity risks sit during a transformation programme and what you can do about them.
Cybersecurity in digital transformation means building protection into every stage of a change programme. Rather than treating security as a separate workstream, it becomes part of how new systems are selected, configured and adopted.
This matters because transformation projects change the way data moves through your organisation. New cloud applications, API connections and collaboration tools each add potential entry points. The UK Cyber Security Breaches Survey 2025/2026 found that 65% of medium businesses and 69% of large businesses identified a cyber breach or attack in the preceding 12 months.
When you migrate systems to the cloud, connect a new CRM to your email platform or introduce remote collaboration tools, each integration creates a new pathway that needs protecting. Permissions may be configured too broadly. Legacy credentials may carry over from old systems. Temporary workarounds often become permanent fixtures.
Growth-focused teams tend to prioritise speed over review. That urgency makes sense, but it frequently leaves gaps in identity and access management that attackers can exploit.
Adding security after a transformation is complete means fitting controls around systems already in production. That approach costs more, causes more disruption and delivers less protection than getting it right during the design phase.
When security is included from the start, you can evaluate each new tool against your risk profile, set access policies before users are onboarded and test your incident response plan before it is needed. Strata Digital helps organisations embed this thinking into transformation planning so that progress and protection move together.
Mid-market companies often have enough complexity to face serious threats but not always enough resource to watch every angle. Two areas are particularly easy to underestimate.
Every SaaS tool you connect to your environment introduces a dependency on that provider's security practices. The same UK government survey found that only 15% of businesses formally reviewed the cyber risks posed by their immediate suppliers, falling to just 6% for the wider supply chain.
A compromised integration can expose customer data, payment credentials or internal communications. Before connecting a new platform, check how it stores your data, what access it needs and whether its security controls meet your standards.
New workflows change the way people handle information. A finance team using a new approval process, a sales team moving to a different CRM or a marketing team adopting a new analytics platform all represent moments where familiar routines disappear and mistakes become more likely.
Phishing remains the most common attack method, affecting 38% of UK businesses according to the same government survey. During a transformation, when staff are learning new tools and receiving unfamiliar system notifications, the risk of someone clicking a malicious link increases. Practical training that relates to the tasks your people actually perform makes a measurable difference.
You do not need to be a security specialist to make cybersecurity part of your transformation plan. These steps give mid-market growth teams a practical starting point.
Before making changes, document your current environment. Map the systems you rely on, the data they hold, who has access and how that access is controlled. This baseline gives you a clear reference point for measuring improvement. It also helps you spot risks that might otherwise carry over into new systems.
Strata Digital approaches this through digital audit and advisory work that examines systems, processes and ownership together so recommendations connect to actual business risks.
Cybersecurity during a transformation is not just an IT responsibility. Leadership needs to understand the risk implications of each project phase. Operations teams need clear processes for reporting concerns. People across the business need guidance that fits the tools they are using.
The UK government's research found that only 19% of businesses provided any form of cyber security training in the past 12 months. For mid-market teams going through significant change, that figure should be far higher. Align your training programme with your transformation timeline so guidance arrives before the tools do.
Strata Digital supports organisations with digital business transformation, digital audit and digital training services. When your organisation is going through change, that combination helps you assess risks early, align teams and build stronger operating practices as new systems are introduced.
This advisory approach is useful when your team is balancing growth, governance and capability-building at the same time. It keeps cybersecurity tied to the business outcomes your transformation programme is supposed to deliver.
Expanding your attack surface through new integrations and cloud services without reviewing their security is the most common risk. Each new connection adds a potential entry point that needs appropriate controls and monitoring.
Start with a risk baseline and prioritise the gaps that carry the highest business impact. Strata Digital helps teams focus effort on the issues most likely to affect delivery, operations and customer trust.
People are learning new tools and processes, which makes them more susceptible to phishing and social engineering. Strata Digital connects training to practical day-to-day work so new habits are easier to adopt.
Before. A digital audit creates a baseline of your current risks and access arrangements. Building security into each phase of the transformation is more effective and less costly than applying controls after systems are live.
Strata Digital combines transformation advisory, digital audit and training services to help organisations plan change more carefully. That gives teams a clearer view of risk, priorities and execution before major digital decisions are locked in.
