## Offering Details

| Criteria | AIG CyberEdge, CyberEdge Plus and CyberEdge PC | Marsh McLennan Agency cyber (official overview) |
| --- | --- | --- |
| Role in This Line | AIG markets three distinct cyber forms: CyberEdge, CyberEdge Plus and CyberEdge PC. AIG says coverage may be bought as a standalone CyberEdge policy or endorsed onto selected Financial Lines, Property and Casualty policies; the forms are not interchangeable descriptions of one coverage grant. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: AIG’s U.S. CyberEdge page; endorsement availability is stated only for selected policies. AIG’s legal footer says policies are written by subsidiaries or affiliates and coverage depends on underwriting and policy language..) | Marsh McLennan Agency describes arranging cyber for the audience stated on the cited product page. [6](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Company-reported; scope: cyber marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Who It’s For | AIG describes cyber coverage and risk services for organizations and clients. The reviewed product page does not publish a complete eligible-industry, revenue or security-control appetite; a particular applicant’s eligibility remains subject to underwriting. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: Audience stated by AIG on its U.S. CyberEdge marketing page; no application eligibility schedule was reviewed..) | Organizations managing cyber exposure; exact insurer, policy form, and eligibility are placement-specific. [6](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Company-reported; scope: cyber marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Coverage Features | AIG describes CyberEdge as addressing breach-related financial costs such as response, data restoration, network interruption and cyber extortion. CyberEdge Plus is described for physical-world losses caused by a cyber event, including business interruption, property damage and physical injury; CyberEdge PC is described as excess of traditional property and casualty policies on a difference-in-conditions/difference-in-limits basis. The page says actual coverage depends on the facts and policy terms, conditions and exclusions. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: Product summaries on AIG’s U.S. page, preserving differences among the three forms. Examples are not a promise that any loss or expense is covered under an issued policy..) | The cited product page describes cyber liability and a cyber-risk management strategy as part of the executive and professional risk offering. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [6](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Company-reported; scope: cyber marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience.

Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [6](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| Risk Services | AIG describes cyber risk assessment, threat intelligence, alerts about known vulnerabilities, and a Cyber Resiliency Program. The page says these services help clients assess and improve cyber resilience; it does not promise that they prevent a breach or are available on identical terms with every form. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: Company-described cyber risk services on AIG’s U.S. CyberEdge page; product and account applicability should be confirmed in the quote..) | Confirm in your quote. |
| How to Apply | AIG links a U.S. Cyber underwriting application and invites brokers to contact its national product and distribution teams. The page does not say that submitting an application results in a quote, acceptance or binding. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: Application and broker contact links on AIG’s U.S. CyberEdge page; no completed application or binding workflow was reviewed..) | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement. The page does not establish a quote, bind, or coverage-effective timeline.

| Claims Support | AIG says its cyber insureds can use a 24/7 claims hotline and that its claims team works with specialized legal and forensic firms on incident response. AIG’s example also describes assistance with regulatory disclosures and notifications. These service statements do not guarantee claim acceptance, payment or a particular response time. [3](https://www.aig.com/us/CyberEdge "Cyber Insurance — CyberEdge") (Evidence: Company-reported; scope: Company-reported services and example on AIG’s CyberEdge page; policy terms and the circumstances of a loss control any claim..) | Confirm in your quote. |

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.
