SMEs, or Small and Medium-sized Enterprises, are businesses with a limited number of employees and revenue compared to large corporations. In cybersecurity, SMEs are particularly vulnerable because they often lack the resources, expertise, and dedicated IT staff necessary to implement robust security measures. This makes them attractive targets for cybercriminals, who may exploit their weaker defenses through phishing, ransomware, or other cyberattacks. Protecting SMEs requires tailored security solutions, employee awareness training, and sometimes external support to ensure data and operational security. Governments and industry bodies often provide guidelines and assistance to help SMEs improve their cybersecurity posture.
