Key Differences in Cyber Insurance
Standard Product or Brokered Capacity
Liberty Mutual lists Liberty Cyber Resolution and describes first- and third-party coverage with proactive mitigation. Marsh’s cyber practice places and advises on policies without underwriting them; its Cyber ECHO facility can provide more than $200 million in excess capacity per client. That figure describes facility capacity, not a guaranteed limit for a buyer. Ask Marsh for the primary insurer and tower structure, and Liberty Mutual for its quote’s available limit. 3 8
Claims Advocacy and Incident Support
Marsh says its claims and incident-management specialists review cyber claims, support litigation management, prepare proof of loss with forensic accountants, and advocate with insurers. Liberty Mutual’s product page mentions proactive risk mitigation but does not describe cyber claims advocacy in the record. If support after a breach matters, ask Marsh how its specialists engage and Liberty Mutual who coordinates the claim. 10 3
Placement for Middle-Market Buyers
Marsh McLennan Agency lists incident response, interruption, extortion, data restoration, and security/privacy liability as core cyber coverages, with additional options available. Liberty Mutual’s page gives broad first- and third-party coverage labels without itemizing those terms. Ask for a side-by-side schedule of core and optional coverages, including ransomware and reputation-related income loss. 11 3
What to Confirm in Cyber Insurance Quotes
- Ask Marsh to name the primary and excess insurers, attachment points, reinstatements, and claims advocate contact. 9 10
- Ask Liberty Mutual for the specific first-party events, response services, and limits included in its proposed form. 3
- Confirm whether Marsh’s middle-market coverages and any optional media, regulatory, or reputation extensions are included in your quote. 11

Marsh’s global Trustpilot profile has a poor 1.3/5 score. Treat it as a service warning to investigate with your proposed team; it does not isolate US commercial accounts.[2][4][7]
