Growing UK businesses are facing a widening cybersecurity gap as recruitment, remote access and cloud operations expand faster than internal teams can establish clear responsibility for protecting them.
The pressure is particularly acute for smaller companies, where a limited IT function may already be responsible for onboarding staff, handling helpdesk requests and changing systems during the working day. Monitoring logs overnight and responding to alerts at weekends require dedicated capacity, rather than an assumption that someone will notice a problem.
The issue is becoming more significant as hybrid working makes the traditional office perimeter less relevant. Employees may connect through home broadband, shared routers or public Wi-Fi, while personal laptops and phones can introduce uncertainty over software updates, encryption and what happens when a device is lost.
A broader attack surface
The 2025 UK Government Cyber Security Breaches Survey found that 43% of businesses had identified a breach or attack during the preceding year. The figure illustrates the scale of the challenge facing companies that are expanding their digital operations without necessarily expanding their security resources at the same pace.
Remote access also changes how phishing attempts reach employees. An unusual request for information or a payment may be harder to challenge when staff are working away from colleagues who might otherwise question it. Security planning therefore needs to cover not only company equipment, but also the networks and working arrangements through which business traffic travels.
For directors, that creates a series of practical questions about the controls supporting hybrid work. These include whether virtual private network and remote-desktop connections use multi-factor authentication, whether unmanaged devices are prevented from accessing business systems, and who checks permissions for cloud services.
Cloud responsibility must be defined
Cloud operations bring a separate set of risks. Companies can place too much confidence in default settings, while broad sharing permissions or unclear ownership of user access can leave sensitive systems exposed. The central management issue is not simply whether a provider operates secure infrastructure, but which security tasks remain with the customer.
The cloud shared responsibility model separates the protection of the provider’s infrastructure from customer-side duties such as identity and access management. Provider documentation should make that boundary clear, but businesses still need to establish who is responsible for checking permissions and ensuring that security arrangements keep pace with growth.
| Area of exposure | Management issue |
|---|---|
| Home and public networks | Business traffic may travel outside direct company control |
| Personal devices | Updates, encryption and lost-device procedures may be uncertain |
| Cloud services | Access ownership and sharing permissions can become unclear |
| Out-of-hours alerts | Monitoring requires separately allocated capacity |
Growth is also a capacity decision
The risks do not follow normal office hours. A company that adds employees, accounts and systems must decide who will review alerts, manage access and respond when something appears abnormal. Treating these duties as an informal extension of an already busy IT role can leave important activity uncovered overnight or at weekends.
For UK SME directors, the technology challenge is therefore closely linked to operational planning. Every recruitment or systems decision can increase the number of accounts, devices and connections that need protection. Without clearly assigned ownership, the business may know that security matters while still lacking a reliable process for maintaining it.
Hybrid working and cloud adoption can support expansion, but they also distribute responsibility across staff, devices, networks and service providers. Establishing the boundary between those responsibilities, and ensuring that monitoring has dedicated capacity, is becoming a necessary part of managing growth rather than a separate technical concern.
