As the CEO of ClickDo, I’ve seen the digital landscape evolve dramatically over the years. The internet has empowered UK businesses to scale, connect, and innovate like never before. But with these opportunities come significant risks, cybersecurity threats that can cripple operations, erode customer trust, and cost millions.
In 2024, the UK saw a staggering 74% of businesses affected by cyber incidents, according to the UK Government’s Cyber Security Breaches Survey. The stakes are high, and as a business owner, you can’t afford to leave your digital doors unlocked.
At ClickDo IT Support, we’ve made it our mission to protect UK businesses from these ever-growing dangers. Cybersecurity isn’t just a technical issue, it’s a business imperative.
In this guide, I’ll walk you through the most pressing cybersecurity threats facing UK businesses today and share actionable steps to safeguard your organisation. I’ll also explain why entrusting cybersecurity to IT experts like us is the smartest move you can make. Let’s dive in.
The Cybersecurity Threat Landscape in 2025
Cybercriminals don’t discriminate, they target businesses of all sizes, from startups to FTSE 100 giants. The threats are diverse, sophisticated, and constantly evolving. Here are the most common cybersecurity risks UK businesses face today:
1. Phishing Attacks
Phishing remains the most prevalent cyber threat. These attacks trick employees into sharing sensitive information like login credentials or financial details through fake emails, texts, or websites. In 2024, phishing accounted for 83% of cyber-attacks on UK businesses, per the UK Government’s survey.
Example: A small retail business in Manchester received an email pretending to be from their supplier, requesting urgent payment for an invoice. The email looked legitimate, but it directed funds to a hacker’s account, costing the company £20,000.
2. Ransomware
Ransomware locks businesses out of their systems or data, with criminals demanding payment to restore access. The average ransom demand in the UK soared to £850,000 in 2024, according to Sophos’ State of Ransomware report.
Example: A London-based law firm had its client data encrypted by ransomware. Unable to access critical case files, they faced a £500,000 ransom demand. Even after paying, recovery wasn’t guaranteed, and their reputation took a hit.
3. Malware
Malware, including viruses, worms, and spyware, infiltrates systems to steal data or disrupt operations. It often spreads through malicious downloads or unsecured websites.
Example: A UK manufacturing company downloaded a seemingly harmless software update, only to find it was malware that compromised their supply chain data, leading to weeks of downtime.
4. Insider Threats
Not all threats come from outside. Disgruntled employees, careless staff, or contractors can expose sensitive data, intentionally or accidentally. Insider threats caused 20% of UK data breaches in 2024, per Verizon’s Data Breach Investigations Report.
Example: An employee at a Birmingham consultancy shared login details on a phishing site, unknowingly giving hackers access to client contracts worth millions.
5. Distributed Denial-of-Service (DDoS) Attacks
DDoS attacks overwhelm websites or servers with traffic, rendering them unusable. E-commerce businesses are prime targets, losing revenue during downtime.
Example: A UK online retailer was hit by a DDoS attack during Black Friday, crashing their website and costing £100,000 in lost sales.
6. Supply Chain Attacks
Hackers target weaker links in your supply chain to gain access to your systems. With UK businesses increasingly reliant on third-party vendors, these attacks are on the rise.
Example: A Bristol-based logistics firm was breached when a supplier’s outdated software was exploited, exposing shipment data to criminals.
Why Cybersecurity Is a Job for Experts?
Running a business is hard enough without trying to become a cybersecurity expert overnight. The threats I’ve outlined are complex, requiring specialised tools, knowledge, and constant vigilance to counter.
At ClickDo IT Support, we’ve seen businesses try to handle cybersecurity in-house, only to realise too late that it’s a full-time job. Patching software, monitoring networks, and training staff isn’t something you can squeeze into a busy schedule, it demands dedicated expertise.
Cybersecurity isn’t just about installing antivirus software; it’s about building a fortress around your data, systems, and reputation. Mistakes can be costly, not just financially but legally. Under the UK’s Data Protection Act 2018 and GDPR, businesses can face fines of up to £17.5 million or 4% of annual turnover for data breaches. That’s a risk no business should take lightly.
How UK Businesses Can Prevent Cybersecurity Attacks?
As daunting as these threats sound, there’s plenty you can do to protect your business. Below, I’ve outlined practical steps that every UK business should take, informed by our experience at ClickDo IT Support and industry best practices. These measures are most effective when implemented by professionals, but they’re a great starting point for understanding what’s needed.
1. Conduct a Cybersecurity Risk Assessment
You can’t protect what you don’t understand. Start by auditing your systems, networks, and data to identify vulnerabilities. A risk assessment helps you prioritise investments in security.
Action: Map out your digital assets customer databases, payment systems, employee records and evaluate how they could be exploited. IT experts use tools like penetration testing to simulate attacks and uncover weak spots.
Reference: Check the National Cyber Security Centre’s (NCSC) guide on risk management: NCSC Risk Management.
2. Implement Strong Access Controls
Limit who can access sensitive data. Use multi-factor authentication (MFA) to add an extra layer of security beyond passwords. Role-based access ensures employees only see what they need to do their jobs.
Action: Enable MFA on all critical systems, like email and cloud platforms. Regularly review user permissions to prevent unauthorised access.
Example: A Leeds-based charity avoided a breach by requiring MFA, stopping a hacker who had stolen an employee’s password.
3. Train Your Staff
Your employees are your first line of defence and your biggest vulnerability. Regular training on spotting phishing emails, securing devices, and reporting suspicious activity is non-negotiable.
Action: Run quarterly cybersecurity workshops and simulate phishing attacks to test employee awareness. At ClickDo, we offer tailored training to keep staff vigilant.
Reference: The NCSC’s free training resources are a great starting point: NCSC Training.
4. Keep Software Updated
Outdated software is a hacker’s dream. Regularly update operating systems, applications, and security tools to patch vulnerabilities.
Action: Use automated patch management tools to stay current. IT experts can monitor updates to ensure nothing slips through the cracks.
Example: A Nottingham retailer avoided a ransomware attack by updating their point-of-sale system, which had a known exploit.
5. Deploy Advanced Security Tools
Firewalls, antivirus software, and intrusion detection systems are your digital bodyguards. Endpoint detection and response (EDR) tools can stop threats before they spread.
Action: Invest in enterprise-grade solutions like CrowdStrike or Sophos, managed by professionals who can configure and monitor them effectively.
Reference: Sophos’ cybersecurity solutions are highly rated: Sophos Solutions.
6. Back Up Data Regularly
If ransomware strikes, backups can save your business. Store data securely offsite or in the cloud, and test restores to ensure they work.
Action: Schedule daily backups and encrypt them to prevent unauthorised access. IT experts can set up automated, secure backup systems.
Example: A Cardiff-based consultancy recovered from a ransomware attack in hours thanks to robust backups, avoiding a £200,000 ransom.
7. Develop an Incident Response Plan
No system is 100% secure. A clear plan for responding to breaches minimises damage and downtime.
Action: Create a step-by-step guide for identifying, containing, and reporting incidents. Include contact details for IT support and legal advisors. Test the plan annually.
Reference: The NCSC’s incident management guide is invaluable: NCSC Incident Management.
8. Secure Your Supply Chain
Vet third-party vendors for cybersecurity standards. Ensure contracts include clauses for data protection and regular audits.
Action: Ask suppliers to provide evidence of compliance with standards like ISO 27001. IT experts can assess vendor security on your behalf.
9. Comply with Regulations
GDPR, the Data Protection Act, and industry-specific regulations (like PCI DSS for payment processors) aren’t optional. Non-compliance can lead to fines and reputational damage.
Action: Work with IT professionals to audit compliance and implement necessary controls, like data encryption and privacy policies.
Reference: The Information Commissioner’s Office (ICO) offers GDPR guidance: ICO GDPR Guide.
10. Partner with IT Experts
Cybersecurity is a marathon, not a sprint. Partnering with a trusted IT provider ensures your defences stay ahead of threats. At ClickDo IT Support, we offer end-to-end cybersecurity services, from risk assessments to 24/7 monitoring.
Action: Schedule a consultation with an IT provider to review your current setup and build a tailored security strategy.
