Small businesses are increasingly vulnerable to cyber threats. With limited resources and often less robust security measures, small and medium-sized businesses become prime targets for cybercriminals. Recent data underscores the urgency, with 50% of small businesses in the UK experienced a cyber attack in 2024.
Understanding the most prevalent cyber threats for businesses is the first step towards knowing how to implement total safeguarding. We have compiled a handy list of the top five cyber security threats for small businesses today, so that you can stay updated and in the know:
The 5 Most Common Cyber Threats Facing Small Businesses
1. Phishing Attacks
Phishing remains one of the most common cyber security threats, accounting for 93% of cyber crimes experienced by UK businesses. These attacks involve deceptive emails or messages that trick employees into revealing sensitive information or clicking malicious links.
Protective Measures:
- Implement comprehensive email filtering solutions.
- Opt for HornetSecurity spam and malware protection.
- Conduct regular employee training on identifying phishing attempts.
- Establish clear protocols for reporting suspicious communications.
2. Ransomware
Ransomware attacks have seen a significant uptick, with the percentage of businesses experiencing such crimes doubling from less than 0.5% in 2024 to 1% in 2025. These attacks encrypt business data, demanding payment for its release. This leads to significant operational disruptions and financial losses.
Protective Measures:
- Maintain regular, secure backups of critical data.
- Opt for HornetSecurity 365 Total Backup.
- Keep all systems and software up to date with the latest security patches.
- Utilise advanced endpoint protection solutions.
3. Supply Chain Attacks
Supply chain attacks where cybercriminals infiltrate a business through its third-party vendors account for 15% of small business breaches in 2025. This is a very specific and targeted way that criminals can break a business down, and demonstrates why cyber security measures for businesses are crucial to prevent these various methods of attack.
Protective Measures:
- Conduct thorough due diligence on all third-party vendors.
- Implement strict access controls and monitor third-party activities.
- Establish clear security requirements in vendor contracts.
4. AI-Powered Cyberattacks
Cybercriminals are increasingly leveraging artificial intelligence to conduct sophisticated attacks, including crafting highly convincing phishing emails and automating vulnerability detection. Nearly 90% of UK businesses are vulnerable to such AI-driven cyberattacks.
Protective Measures:
- Stay informed about emerging AI-related threats and adapt security strategies accordingly.
- Foster a culture of continuous learning surrounding business IT security.
5. Deepfake Technology
Deepfake technology, which uses AI to create realistic fake videos or audio, poses a growing threat. These can be used to impersonate company executives or manipulate employees into divulging sensitive information. The number of deepfakes online surged by 550% from 2019 to 2023.
Protective Measures:
- Implement verification protocols for sensitive communications.
- Educate employees about the existence and risks of deepfakes.
- Utilise authentication tools to confirm the identity of individuals in communications.
