In 2025, cybersecurity has evolved beyond technical considerations to become a fundamental business priority. Small businesses, mid-market companies, and enterprises alike face unprecedented digital threats that target sensitive information across networks, devices, and servers. Modern organisations require sophisticated, next-generation antivirus systems that protect comprehensively against evolving threats. This guide explores why robust cybersecurity solutions are no longer optional but essential for business continuity and competitive advantage in today's interconnected marketplace.
The numbers tell a compelling story. Between 43-45% of UK businesses reported experiencing a cyber attack or security breach in the past year, slightly improving from 50% in 2024, but still alarmingly high. Medium and large businesses continue to be primary targets, with 67-74% reporting breaches or attacks.
Phishing remains the dominant threat vector, affecting 83-93% of businesses that experienced cybercrime. Perhaps most concerning is the doubling ransomware incidents, now affecting approximately 19,000 UK companies. This is why advanced threat detection capabilities have become essential for business owners who want to keep their business secure.
Despite these sobering statistics, there's an apparent disconnect between risk and readiness:
This preparedness gap leaves many businesses unnecessarily vulnerable, highlighting why antivirus protection features that work best are crucial for businesses to protect themselves from cyberthreats.

These services can make the difference between vulnerability and security for medium-sized and small businesses.
Why do businesses need antivirus software?
Antivirus software is essential for companies because it helps protect sensitive data from malware, ransomware, and other cyber threats that can compromise operations. For small and medium-sized business owners, antivirus protection provides a critical first line of defence against increasingly sophisticated attacks.
What makes next-generation antivirus different from traditional antivirus solutions?
Next-generation antivirus uses advanced technologies like machine learning, artificial intelligence, and behavioural analysis to detect and block threats, rather than relying solely on signature-based detection. This proactive approach helps protect businesses from zero-day exploits and previously unknown threats that traditional solutions might miss.
How do I know which antivirus solution is right for my business?
Consider factors like the size of your business, industry-specific requirements, budget, and the types of devices you need to protect. Many providers offer solutions specifically built to help protect small businesses. Consider whether you need features like device security, server antivirus, or additional online protection capabilities.
Do I need an antivirus if I have a firewall?
Yes. Firewalls and antivirus software perform different functions in your business network security. Firewalls control incoming and outgoing network traffic, while antivirus software detects and removes malicious code that has already entered your system. Your business needs both for comprehensive protection.
How often should I update my antivirus software?
Most modern solutions update automatically. However, it's best practice to verify that your protection features are current at least weekly. Regular updates ensure your defence against cyberthreats includes the latest threat intelligence.
What happens if my business gets hacked despite having an antivirus?
Even with the best antivirus protection, breaches can still occur. This is why it's crucial to have an incident response plan. A comprehensive security strategy includes threat detection, backup solutions, recovery procedures, and staff training. Businesses that prepare for potential breaches recover more quickly and with less financial impact.
Can small businesses afford comprehensive antivirus protection?
Yes. There are many antivirus solutions designed for small businesses with various price points. The cost of protection is significantly lower than the potential cost of a breach. Many providers offer scalable solutions that grow with your business, allowing you to safeguard your operations without unnecessary expense.
How do I choose between cloud-based and on-premise antivirus solutions?
Cloud-based antivirus typically offers better protection for remote workers, easier management capabilities, and automatic updates without straining your IT resources. On-premise solutions may provide more customisation options and can work in environments with limited internet connectivity. The best choice depends on your specific business model, IT infrastructure, and security requirements.
What protection features should I look for beyond basic antivirus?
Look for solutions that include advanced threat detection, ransomware protection, network monitoring, email security, and centralised management dashboards. For businesses with remote workers, features like VPN services and online privacy protections are also valuable additions that help secure your network regardless of where your team works.
Do I need different antivirus solutions for other devices?
Ideally, choose a comprehensive security solution that protects all types of devices, including Windows servers, workstations, mobile devices, and macos systems. Unified protection across platforms simplifies management and ensures consistent security policies across your entire business infrastructure.
Don't wait for a breach to prioritise your cybersecurity. Whether you run a small business antivirus system or need enterprise-level solutions, taking proactive steps today will help protect businesses from the growing landscape of cyber threats.
