## What Is WTW?

## What Is Cyber Insurance?

Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. [10](https://www.ftc.gov/business-guidance/small-businesses/cybersecurity/cyber-insurance "Cyber Insurance") [11](https://www.aig.com/content/dam/aig/america-canada/us/documents/business/cyber/cyberedge-wording-sample-specimen-form.pdf "CyberEdge specimen policy")

## What Are the Key Differences Between Marsh McLennan Agency and WTW Cyber Insurance?

### Cyber within broader risk programs

WTW’s annual report lists cyber insurance among FINEX solutions, and its Digital Infrastructure Protector includes cyber protection within a broader data-center solution. MMA describes cyber liability and risk management as part of its executive and professional risk offering. A data-center operator should ask WTW how cyber fits the broader program; another buyer should ask both brokers to specify standalone and combined options. [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K") [3](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

### Binding and policy review

WTW’s North American terms say an insurer quote does not itself confirm coverage; after the client orders binding, WTW seeks a formal insurer commitment and reviews the binder and policy against negotiated terms. MMA’s claim directs buyers to an adviser to discuss placement. If timing matters, ask both who confirms binding and who checks the issued documents against the agreed coverage. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [3](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")

## What Should You Confirm in Marsh McLennan Agency and WTW Cyber Insurance Quotes?

- Ask WTW whether your risk fits its data-center cyber solution, who confirms binding and how it checks the final wording. [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K") [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")
- Ask MMA whether its proposal includes a broader data-center program, and who will verify the binder and policy against negotiated terms. [3](https://www.marshmma.com/us/solutions/cyber.html "Cyber | MMA")
