Key Differences in Crime Insurance

Marsh Placement Versus Relm’s Crime Line

Marsh’s financial and professional liability practice places commercial crime, and Marsh McLennan Agency also places crime bundled with fidelity. You engage Marsh’s crime specialists directly. Relm lists Commercial Crime as one of three crime products on its crime insurance page, alongside Digital Asset Crime and Smart Contract Crime, and sells crime coverage through insurance brokers rather than a direct online quote. Neither reviewed page names a specific issuing insurer. 5 6 9

White-Collar and Hacking Risks Versus DeFi Methods

Marsh lists employee white-collar fraud, third-party fraud, collusion, hacking or computer-related crime, social-engineering fraud and tangible-asset theft, and notes that crime policies usually exclude ransomware though most cover funds stolen by hackers. Relm’s commercial crime coverage addresses embezzlement, forgery and funds-transfer fraud, alongside crime risks tied to digital infrastructure and alternative asset models. Relm says its crime underwriting considers flash-loan attacks that drain DeFi protocol liquidity and oracle manipulation. 5 9

Who It’s For

Not described in the reviewed sources.

Coverage Features

It notes that crime policies usually exclude ransomware, though most cover direct financial losses from funds stolen by hackers. 5Company-reported.

Crime page 'What is Commercial Crime Coverage?' section; the issued policy and declarations control.

Relm says its crime underwriting considers emerging attack methods such as flash-loan attacks that drain DeFi protocol liquidity and oracle manipulation that tricks smart contracts into faulty decisions, in addition to legacy fraud vulnerabilities. 9Company-reported.
