Cyber-focused program or broader brokerage

Coalition requires an appointed broker to access its coverage; its disclosed U.S. producer arranges the policy while the insurer carries policy obligations. Coalition pairs cyber cover with Control security monitoring and offers Tech E&O as a related product, subject to policy terms. MMA describes a broad middle-market brokerage and lists cyber alongside property, workers' compensation, professional liability and auto on its U.S. small-business page. If cyber is the primary need, ask Coalition's broker how its security services are included and conditioned; if coordinating several lines, ask MMA for the proposed insurer and service plan for each. 3 7 8 20 33

Application and renewal work

Coalition says underwriting considers industry, finances, operations and security, and its technology application may need review before a price is released. The company describes cyber renewals beginning 90 days before expiry, with different response requirements for automatic, express and standard paths; automatic renewal does not promise the same premium. MMA's small-business page invites a call and contains a specialist form, but does not explain the form's function or an online bind route. Ask both teams who must complete applications and renewal documents, what deadline applies, and whether the policy renews automatically. 13 12 15 33

Response responsibilities

Coalition describes in-house cyber triage and a response team; this does not establish coverage or claim payment. MMA says it can advocate with insurers on complex business-interruption claims, which likewise does not make it the adjuster or insurer. For a quote, ask for the incident hotline, insurer notice requirements, response-vendor terms and the account team's role after a claim. 9 21
