Key Differences in Cyber Insurance
Published Coverage Detail
Markel’s Cyber 360 page names options including business interruption, eCrime, privacy/security liability, PCI liability, media liability, and technology professional liability. Marsh McLennan Agency describes cyber liability and a cyber-risk management strategy within its executive and professional risk offering, but its overview does not itemize insured events or terms. Markel provides a more specific public menu; an MMA buyer should request the proposal and policy form to see which grants and conditions apply. 3 6
Placement and Consultation
MMA invites organizations to contact an adviser or specialist to discuss placement and does not establish a quote or binding timeline. Markel also invites prospective customers or brokers to contact its underwriting team. The routes are both conversation-led in the reviewed records, but MMA places cyber within an executive-risk practice while Markel presents Cyber 360 as its cyber product; ask which team will handle the account and what application materials are needed. 6 3
Limits and Policy Terms
Neither provider’s overview sets a universal cyber limit or retention. Markel cautions that its Cyber 360 terms depend on the issued policy, and MMA likewise directs buyers to the proposal for actual terms. Request limits, retentions, exclusions, and any sublimits before comparing coverage labels. 3 6
What to Confirm in Cyber Insurance Quotes
- Ask Markel which Cyber 360 options are included and the limit and retention for each. 3
- Ask MMA for the proposed cyber form, included insuring agreements, and adviser responsible for placement. 6
- Compare the named insurer, exclusions, incident-response costs, and any cyber-risk services in the two proposals. 3 6
