An insurance product that comprehensively covers liability for damages, incident response costs, and business interruption losses arising from cyberattacks and data breaches. Against the backdrop of surging ransomware attacks and increasingly sophisticated phishing scams, demand is expanding beyond corporations to include sole proprietors and freelancers.
Coverage Scope and Risks Addressed by Cyber Insurance
Cyber insurance coverage is built on three pillars: "liability coverage," "expense coverage," and "profit coverage." Liability coverage pays damages owed to customers and business partners resulting from personal data breaches. Expense coverage compensates for forensic investigation costs, victim notification costs, call center setup costs, and legal consultation fees incurred during incident response. Profit coverage reimburses lost operating income due to system outages caused by cyberattacks.
Covered risks span a wide range, including data breaches from unauthorized access, data encryption by ransomware, financial losses from phishing scams, service outages from DDoS attacks, and data leaks caused by employee negligence. In recent years, supply chain attacks (intrusion via business partners) and business email compromise (BEC) are increasingly included in coverage as well.
How to Choose Cyber Insurance for Individuals and Small Businesses
When selecting cyber insurance, compare four dimensions: coverage scope, benefit amounts, deductibles, and bundled services. Bundled services are particularly important. Whether a 24/7 incident response team is available when an incident occurs, and whether the insurer arranges forensic investigations on your behalf, can make a decisive difference in minimizing actual damage.
Cyber insurance is worth considering even for sole proprietors and freelancers. In businesses that handle customer personal data (web development, e-commerce operations, consulting, etc.), liability for data breaches can exceed personal assets. Annual premiums vary by business scale and industry, but plans for sole proprietors start at roughly 50,000 to 150,000 yen per year. Combining strengthened security measures with cyber insurance as a safety net represents a realistic approach to risk management.
