Why Are Medium-Sized Businesses Targeted for Cyber Attacks?

11 March 2026

At a Glance

The UK Cyber Security Longitudinal Survey 2026 showed that 82% of organisations reported at least one breach in the past year, with medium-sized firms disproportionately affected. Limited resources, supply chain exposure and human risk increase vulnerability. Strengthening detection, baseline controls, incident response planning and staff awareness is essential for long-term resilience.

UK SME Cyber Attack Statistics 2026

Accounting for 99.8% of the UK business market and 25% of GDP, small firms and mid-sized enterprises are the leading contributors to the UK economy. However, even with their mammoth contributions, they remain vulnerable to cyber threats.

The Cyber Security Longitudinal Survey 2026 has revealed that a staggering 82% of UK organisations have reported at least one cyber security breach in the past 12 months. This percentage concentrates on mid-sized firms, which power the economy.

But what does this number mean for a typical mid-sized organisation? And, why are medium-sized businesses targeted for cyber attacks so frequently?

In our guide, we address these questions and explore how Redpalm’s services can help your mid-sized organisation build stronger defences against cyber attacks.

What the Cyber Security Longitudinal Survey 2026 Reveals

The Cyber Security Longitudinal Survey 2026 is an ongoing study of organisations’ cyber security behaviours. It analyses the trends and links between policies and processes and the likelihood of a cyber security incident.

One of the key findings was that 82% of organisations experienced at least one cyber security incident in the last year. This finding highlights the penetrating nature of digital threats for UK firms, regardless of their size. Along with this staggering number comes the ground-breaking reality that medium-sized businesses are the primary target of attackers.

This survey also highlighted that organisations with better monitoring and certifications were more likely to report incidents with proactive detection and logging mechanisms in place. This may also serve as a wake-up call to firms under-reporting incidents due to poor detection capabilities.

Why Are Medium-Sized Businesses Targeted for Cyber Attacks?

Here are four key reasons why medium-sized businesses are targeted by cyber attacks.

1. Attractive and Easier Targets

Mid-sized firms have unique challenges. They have valuable data or workflows, but may lack the corresponding security and resilience capabilities to match. Compared to larger firms, these firms have limited security budgets or dedicated cyber security teams, which is why attackers may find them easier to breach.

2. Resource Constraints

With limited staff and resources dedicated to cyber security, there are inconsistencies in continuous monitoring, patch management, vulnerability scanning, and threat hunting. These wide security gaps open opportunities for attackers to exploit.

3. Human Element

Phishing attempts still succeed because humans are the weakest link. Attackers use sophisticated social engineering techniques to trick even the most experienced employees.

4. Supply Chain and Third-Party Exposure

Medium-sized UK firms often have multiple supply chain partners and third-party providers. Attackers can exploit these links to infiltrate one partner and reach another.

Lessons Learned from the 82% of Breached Firms

The Cyber Security Longitudinal Survey 2026 and UK SME cyber attack statistics 2026 reveal alarming truths, but more importantly, they bring lessons to be learnt.

1. Detection is as Important as Prevention

What the 82 per cent statistic also highlights is firms detecting and reporting incidents. Only when firms continuously monitor and audit their environment do they have visibility to deliver a quicker response.

Working with a cyber security partner like Redpalm with proactive monitoring and vulnerability assessment services allows organisations to identify threats early and understand weak links before they are exploited.

2. Baseline Security Matters

Following recognised standards such as Cyber Essentials can significantly reduce exposure to common attack vectors. Redpalm is a recognised certification partner for Cyber Essentials and Cyber Essentials Plus, offering firms assessment and remediation services. Having this certification improves your core security controls and demonstrates to your partners and clients that you take your commitment to security very seriously.

3. Plan For Incident Response

Breaches are becoming increasingly sophisticated, with even the strongest defences falling short. This makes incident preparation and response critical. Businesses that invest in structured incident response services are better positioned to contain an incident and recover from it. Our incident response team can offer immediate guidance, with access to digital forensics experts if required, to understand the cause and prevent it from recurring.

4. Integrate Cyber Awareness in Your Culture

Being technically prepared for the organisation is important. But it’s equally important to keep your teams aware and up to date on cybersecurity best practices. Conducting awareness training for staff through simulated exercises can reduce the success rate of attacks targeting human interactions.

Shifting from “If” to “When” in Your Security Strategy

The surveys and statistics speak for themselves. They’re not just a warning but an urgent call to action for businesses, particularly medium-sized UK firms. With a significant majority of firms experiencing cyber incidents, it’s not a matter of if you’ll be targeted, but when.

Now is the time for organisations to modify their cyber security strategy to include long-term resilience measures and integrate security across the board.

Building a resilient security strategy includes:

Proactive defence measures such as firewalls, vulnerability scanning, and endpoint detection
Continuous monitoring and threat detection
Meeting certification and compliance standards like Cyber Essentials
Planning for incident response and recovery
