Key Differences in Cyber Insurance
Broker Strategy and Product Placement
Marsh McLennan Agency describes arranging cyber coverage alongside a cyber-risk management strategy within its executive and professional risk offering. Liberty Mutual lists Liberty Cyber Resolution as its commercial product and directs buyers to a broker or agent. MMA’s reviewed overview does not name a carrier or exact policy form, so ask its adviser to identify the placement; ask Liberty Mutual which entity would issue its quote. 6 3
Public Coverage Detail
MMA identifies cyber liability and risk-management strategy as part of its offering but does not itemize events or terms. Liberty Mutual’s record describes first- and third-party coverage and proactive risk mitigation, without listing limits or covered expenses. Neither overview answers whether a specific event, such as ransomware interruption or regulatory defense, is covered. Request the full form and coverage schedule from both. 6 3
Adviser-Led Application and Limits
MMA invites organizations to discuss placement with an adviser or specialist; its overview sets no universal limit or retention. Liberty Mutual also routes buyers through an agent or broker and does not publish buyer-specific terms. Compare how each adviser gathers underwriting information and have both quote the same limit, retention, and coverage structure. 6 3
What to Confirm in Cyber Insurance Quotes
- Ask MMA to name the insurer, policy form, cyber limit, retention, and risk-management services included in the placement. 6
- Ask Liberty Mutual to identify its issuing entity and detail the events and expenses within its first- and third-party grants. 3
- Send both advisers the same ransomware, interruption, notification, and regulatory scenarios and compare written answers in the quoted forms. 6 3
