Businesses face numerous challenges in implementing cybersecurity measures, including evolving threats, resource constraints, and compliance requirements. The constantly changing nature of cyber threats means that organizations must consistently update their defenses, often incurring high costs for advanced technologies and trained personnel. Additionally, achieving compliance with regulations like GDPR can burden smaller companies lacking adequate resources or expertise. Employee awareness and training are also essential, as many breaches result from human error. Thus, a comprehensive approach that combines technology, policy, and culture is vital for effective cybersecurity.
