What Are the Key Differences Between Aon and Markel Insurance Crime Insurance?

Standalone crime versus cyber eCrime

Aon identifies Crime as a coverage area within its professional-services practice. Markel Insurance describes eCrime within Cyber 360, including expenses from unauthorized money transfers and fake payment instructions, subject to policy terms. This is a meaningful scope distinction: buyers needing broader employee dishonesty, forgery or property protection should not treat a cyber eCrime feature as a full crime policy without reviewing its wording. [1] [4]

What the cited descriptions establish

Aon describes arranging or advising on crime as a brokerage service, not issuing the underlying policy. Markel Insurance says its described resources and coverages are for Cyber 360 policyholders and that availability and terms require the quoted policy. Ask Markel whether eCrime is available in the specific cyber form and whether a separate crime product is available; ask Aon for its proposed insurer and form. [1] [4]

What Should You Confirm in Aon and Markel Insurance Crime Insurance Quotes?

  • Ask Markel whether the quoted Cyber 360 eCrime section responds to employee theft, forged instructions and other events your crime program must address. [1] [4]
  • Ask Aon for covered crime events, insurer and placement entity; ask Markel for Cyber 360 limits, conditions and availability in your jurisdiction. [1] [4]
