What Is Nationwide?
Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business. 9,10,11
What Is Cyber Insurance?
Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. 13,14
Key Differences in Cyber Insurance
Marsh Publishes a Large Excess-Capacity Figure
Marsh says its Cyber ECHO excess facility can provide more than $200 million of cyber capacity per client, with one free reinstatement and a paid second reinstatement for separate events in a policy year. Nationwide’s reviewed overview does not publish a limit or retention. Large organizations should ask whether the Marsh facility can sit above their existing program and obtain a specific Nationwide proposal before comparing available capacity. 6 12
MMA Details Middle-Market Coverage Categories
Marsh McLennan Agency lists investigation and response, network interruption and extra expense, extortion and ransomware payments, data restoration, and security and privacy liability as core coverages; media liability and regulatory defense are additional options. Nationwide describes cyber and data-breach expenses without itemizing agreements. Ask Nationwide to map its policy to the same events and compare which MMA options require endorsements. 8 12
Marsh Describes Claims Advocacy Alongside Placement
Marsh says its claims specialists support litigation management, work with forensic accountants on proof of loss and advocate with insurers. Nationwide’s reviewed cyber overview directs buyers to an agent but does not describe a cyber-specific claims advocacy team. If post-incident support is material, ask Nationwide who will assist with documentation and insurer negotiations, and clarify the scope of Marsh’s services. 7 12
What to Confirm in Cyber Insurance Quotes
- Ask Marsh whether Cyber ECHO is available for your underlying program and how reinstatement pricing works; ask Nationwide to quote its actual primary and excess capacity. 6 12
- Compare which response, interruption, extortion, restoration and regulatory costs are included versus optional, plus any broker claims services. 8 12
