Cyber criminals now use artificial intelligence to automate phishing, scan for vulnerabilities, generate malware, and impersonate businesses at scale. In other words, the barrier to entry for cyber crime has dropped dramatically. Attacks that once required skilled programmers can now be launched using automated AI tools, meaning more criminals can operate faster and more cheaply. The UK government and its cyber defence agencies therefore face a new strategic challenge: protecting millions of small and medium-sized enterprises (SMEs) that often lack dedicated security teams or large budgets. Government cyber defences will need to evolve from reactive protection to proactive national resilience, combining intelligence sharing, automation, regulation, and stronger digital infrastructure. The Scale of the Threat Facing UK Businesses SMEs are the most frequent targets According to the UK Cyber Security Breaches Survey 2025, around 43% of UK businesses reported experiencing a cyber attack or breach in the previous year, representing roughly 612,000 businesses. For medium-sized firms the situation is worse, with a majority experiencing cyber incidents annually. AI is accelerating cyber crime The UK National Cyber Security Centre (NCSC) warns that AI tools will “almost certainly enhance threat actors’ capability” and increase the volume and speed of cyber attacks in the coming years. AI can now be used to: Generate convincing phishing emails and fake messages Identify vulnerabilities in networks rapidly Create adaptive malware Automate cyber reconnaissance Produce deepfake voice or video impersonations As a result, attacks can be launched faster than organisations can patch systems, shrinking the response window dramatically. What UK Government Cyber Defences Must Do Next 1. Build a National “Active Cyber Defence” Shield Automated national protection The UK already operates the Active Cyber Defence (ACD) programme through the NCSC, designed to automatically block common cyber attacks at national scale. Future improvements should include: Automatic blocking of known malicious domains Real-time phishing detection systems Rapid shutdown of fake websites impersonating UK companies AI-based monitoring of malicious infrastructure This model is effective because it protects millions of businesses simultaneously, including those without their own security teams. Why it matters If cyber criminals are using AI to automate attacks, government defences must automate protection at equal or greater scale. 2. Use Defensive AI to Detect Attacks Earlier AI can also work for defenders. Government cyber defence systems should deploy AI-driven detection tools that can: Identify abnormal network behaviour Detect credential theft attempts Spot ransomware activity early Analyse global threat intelligence in real time AI is particularly useful for detecting patterns humans might miss in large datasets. Expert view Cyber security researchers emphasise that AI must be used for automated threat analysis and anomaly detection to counter large-scale automated attacks. In simple terms, AI vs AI cyber defence is becoming inevitable. 3. Strengthen the Cyber Security Baseline for All Businesses One uncomfortable truth of cyber security is that most successful attacks exploit simple weaknesses. Common entry points include: weak passwords unpatched software phishing emails insecure remote access Government policy should therefore push wider adoption of baseline protections such as: multi-factor authentication (MFA) secure cloud configuration regular patching phishing awareness training encrypted backups Phishing remains the most common cyber attack method affecting UK organisations. Government role Government initiatives like Cyber Essentials need stronger incentives so more SMEs adopt them. 4. Improve National Cyber Intelligence Sharing Cyber criminals operate internationally, so intelligence sharing must happen quickly. Government cyber defence must provide real-time threat information to: businesses managed service providers cloud platforms security vendors This could include: live alerts about ransomware campaigns lists of malicious IP addresses new phishing domains targeting UK businesses Faster intelligence distribution helps organisations block threats before they reach networks. 5. Strengthen Software Supply Chain Security Many cyber attacks exploit weaknesses in software suppliers rather than the business itself. Government cyber defence policy must therefore ensure: stronger secure-by-design software standards mandatory vulnerability disclosure faster patching processes better security testing for digital suppliers Supply-chain attacks have become one of the fastest-growing threats globally. 6. Improve Law-Enforcement Disruption of Cyber Criminals Stopping cyber crime also means attacking the criminal infrastructure behind it. Government and law enforcement should focus on: shutting down ransomware groups seizing malicious servers and domains freezing cryptocurrency used for extortion arresting cyber criminals through international cooperation Cyber crime thrives because it is profitable. Reducing the financial incentive is essential. 7. Build Stronger National Cyber Resilience Even the best cyber defences cannot prevent every attack. Government cyber strategy must therefore focus on resilience and recovery, ensuring businesses can recover quickly. This includes promoting: offline backups rapid incident response support clear reporting mechanisms cyber insurance awareness national cyber emergency support teams The goal is simple: make attacks less damaging and recovery faster. Expert Perspective Cyber security specialists widely agree that AI will not necessarily create completely new forms of cyber crime, but it will dramatically increase the scale and speed of existing attacks. The NCSC warns that AI will likely increase the volume of cyber threats and lower the technical barriers for criminals, meaning many more attackers may enter the field. At the same time, the number of significant cyber incidents affecting the UK is rising, reinforcing the urgency of stronger national cyber resilience. The Most Effective Strategy for the UK To protect SMEs from AI-driven cyber crime, UK government cyber defences must focus on five key pillars: Automated national protection systems AI-powered cyber defence tools Mandatory security baselines for businesses Rapid cyber threat intelligence sharing Strong law-enforcement disruption of cyber criminals Secure software supply chains National cyber resilience and recovery planning In short, the UK cannot eliminate cyber attacks entirely. No country can. What it can do is make the country far harder to hack, far faster to detect attacks, and far quicker to recover when breaches occur. Not glamorous. Not cinematic. Just disciplined cyber defence at national scale, which tends to beat dramatic speeches and shiny press conferences most of the time.
