Do Small Businesses Need Cybersecurity?
Yes. Small businesses are disproportionately targeted by cyber attacks because they typically have weaker defences than large organisations. The UK government's Cyber Security Breaches Survey 2025 found that 43% of UK businesses experienced a cybersecurity breach or attack in the past 12 months.
Direct Answer
Yes. Small businesses are disproportionately targeted by cybercriminals — 43% of UK businesses experienced a breach in 2025 (DSIT). SMEs hold valuable data but invest less in security than enterprises, making them attractive targets. The cost of a managed cybersecurity service (£15–£25/user/month) is far lower than the average breach cost of £3,550.
Why Small Businesses Are Targeted
Attackers target small businesses for several practical reasons.
Weaker Defences
Small businesses often lack dedicated security staff, relying on basic antivirus and hoping for the best. Attackers exploit this gap.
Valuable Data
Small businesses hold customer data, financial records, and intellectual property. This data has value to attackers whether through ransom, fraud, or resale.
Supply Chain Entry
Attackers compromise small businesses to gain access to their larger clients. If you work with enterprise customers, your security is their concern too.
Low Detection Rates
Without monitoring, small businesses may not detect a breach for weeks or months — giving attackers time to extract maximum value.

Frequently Asked Questions
Phishing emails are by far the most prevalent threat. 85% of businesses that experienced a breach identified phishing as the attack vector (DSIT 2025). Beyond phishing, small businesses face ransomware, business email compromise, and credential theft. Attackers favour smaller firms precisely because they tend to lack dedicated security staff and rely on basic controls that are easier to bypass.
Yes. Managed cybersecurity for small businesses typically costs £15-£25 per user per month, covering endpoint protection, email filtering, and monitoring. Compare this with the average cost of the most disruptive breach at £3,550 (DSIT 2025) — a figure that rises steeply when data loss or regulatory fines are involved. Prevention is considerably cheaper than recovery for businesses of any size.
At a minimum, every small business should have multi-factor authentication on all accounts, email filtering to block phishing, endpoint protection on every device, regular patching, and tested backups. Only 40% of UK businesses have two-factor authentication enabled (DSIT 2025), despite it being one of the most effective and affordable controls available. These basics stop the majority of commodity attacks targeting SMEs.
