Business Network Interruption coverage is a critical component of many cyber insurance policies, designed to protect organizations from financial losses resulting from a disruption to their computer systems or networks due to a cyber event. This coverage typically reimburses lost income, extra expenses, and operational costs incurred when a business is unable to operate normally following a cyberattack, such as ransomware, DDoS attacks, or other malicious incidents that disable critical systems.
Unlike traditional insurance, which generally requires physical damage to trigger coverage, business interruption coverage responds to virtual disruptions. It may also extend to include outages at third-party providers, such as cloud services or IT vendors that an insured uses and whose systems are essential to an insured’s business operations. This is especially important in today’s interconnected environment, where many companies rely on external platforms to deliver services or maintain data integrity.
Cyber insurance policies vary by carrier in terms of business interruption coverage definitions, liability limits, waiting periods before claims can be filed, and the types of incidents covered. Therefore, it’s essential for businesses to evaluate their specific risk exposures and review policy details carefully. With the rise in frequency and sophistication of cyber threats, having business network interruption coverage can be vital in ensuring financial stability and operational resilience after a network disruption.

Example: e-Commerce Business Network Interruption
Scenario:
A mid-sized e-commerce company relies heavily on its online platform for daily sales. One morning, the company’s IT team detects a ransomware attack that encrypts critical files and brings down the entire website. Customers are unable to place orders, and internal systems used for inventory and order processing are inaccessible.
Impact:
The outage lasts for 5 days while cybersecurity experts work to contain the breach, restore backups, and secure the network. During that time, the business loses approximately $150,000 in revenue and incurs an additional $30,000 in costs related to IT forensics, temporary call center support, and expedited shipping to fulfill delayed orders.
Business Network Interruption Coverage Response:
The company files a claim under its cyber insurance policy, which includes Business Network Interruption coverage. After a 12-hour waiting period (as outlined in the policy), the insurer reimburses the company for lost income during the downtime, extra expenses incurred to resume operations, and the cost of emergency IT services.
Outcome:
Thanks to Business Network Interruption coverage, the company receives a claim payment totaling $180,000. This financial support helps the business recover quickly, maintain customer trust, and avoid a significant long-term financial setback.
