## Summary

[4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

## What Is Alliance Risk?

Alliance Risk suits tech startups from pre-seed through IPO that want a broker to review their tech E&O policy for free and shop specialist insurers; if you want to buy online in minutes, use a digital insurer. Quotes take 24 hours to ten business days, depending on your risk. [1](https://joinalliancerisk.com/technology-insurance/ "Technology Insurance") [2](https://joinalliancerisk.com/technology-errors-omissions-insurance-tech-eo/ "Tech E&O Insurance") [3](https://joinalliancerisk.com/get-a-quote/ "Get a Quote")

[Alliance Risk profile](https://spot.insure/insurance-providers/alliance-risk)

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [6](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [7](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## What Is Directors and Officers Insurance?

D&O insurance can help pay covered defense costs and losses from claims against company leaders over management decisions. If your organization has a board or executives, check whether the company itself is insured and whether legal bills reduce the limit. [9](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [10](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [11](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage")

## Key Differences in D&O Insurance

### Limit Guidance and Buyer Profile

Alliance Risk recommends D&O limits by employee count and location, including higher ranges for multistate and California or New York risks. Aon explains Side A, B and C structures but does not state buyer-specific limits. Compare Alliance Risk’s starting guidance with the actual limit and exclusions in the carrier quote Aon proposes. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

### Broker Structure and Quote Terms

Alliance Risk describes small-business management-liability placements, while Aon discusses public and private company program design. Ask Alliance Risk whether D&O shares limits with EPL or fiduciary coverage, and ask Aon to identify the carrier and structure for each layer. The published summaries do not settle those terms. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance")

## What to Confirm in D&O Insurance Quotes

- Ask Alliance Risk whether D&O shares an aggregate with EPL or fiduciary; ask Aon for insurer, Side A/B/C limits and exclusions. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)")

## Offering Details

| Criteria | Alliance Risk Directors & Officers (D&O) Insurance | Aon Directors and Officers Liability brokerage and risk-advisory offering |
| --- | --- | --- |
| Role in This Line | Alliance Risk places D&O insurance as a broker: it reviews a company's existing D&O program and markets the risk to carriers that specialize in management liability. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page; Alliance Risk does not underwrite the policy itself..) | Aon markets D&O broking and advisory services, including insurer selection and program design. It does not issue the described coverage or name the carrier for a buyer’s placement. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance..) |
| Issuing Insurer | The reviewed D&O page does not name the insurer that would issue a policy; it says Alliance Risk markets a company's risk to carriers that specialize in management liability, so the issuing insurer depends on the placement. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Not publicly disclosed; scope: D&O product page as read on 2026-09-23..) | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Not found in reviewed sources; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed. This does not establish that no insurer or producing entity is available..) |
| Who It’s For | Alliance Risk says D&O is relevant to venture-backed and public companies, high-risk industries such as fintech, healthcare, real estate and financial services, companies going through M&A, IPO or leadership changes, nonprofits, and small private companies without outside investors. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page; eligibility for a particular company depends on underwriting..)<br><br>Alliance Risk says a company should turn on D&O coverage at its first priced funding round, because institutional investment brings personal exposure for directors and officers from day one. [5](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: Management liability page's program-staging guidance, describing D&O specifically among the three bundled lines..) | Aon describes D&O services for public and private companies and discusses executives, directors, managers and board members. This is a target-audience description, not an underwriting eligibility schedule. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Audience stated by Aon on its global capability page; this does not establish a specific applicant’s eligibility or placement availability by U.S. state..) |
| Coverage Features | Alliance Risk describes D&O policies it places as having three parts: Side A for individual directors and officers when the company cannot indemnify them, Side B reimbursing the company for indemnification costs, and Side C covering the company directly for certain liabilities. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page; actual policy structure and whether sides are combined or separately limited depend on the carrier and the policy as issued..)<br><br>Alliance Risk lists standard D&O exclusions it sees, including fraud and intentional misconduct, criminal acts, bodily injury and property damage, and often prior acts before the policy started; it says employment practices and ERISA benefit-plan claims are typically excluded and need separate EPLI or fiduciary liability coverage. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page; exclusion wording varies by carrier and the policy as issued..) | Aon explains D&O policies generally through Side A individual protection when company indemnity is unavailable, Side B reimbursement when the company indemnifies a director or officer, and Side C entity coverage, with different descriptions for public and private companies. It notes exclusions can apply; an issued policy determines the actual scope. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control..) |
| Limits and Retentions | Alliance Risk publishes indicative Side A limit and premium ranges: mid-size companies ($5M-$50M revenue) typically carry $2M-$5M in Side A limits, and larger private companies $5M-$25M or more. It shows overall D&O premium bands from $2,500-$10,000 for small private companies up to $50,000-$500,000 for large private companies, noting fintech, crypto and venture-backed companies often pay 2-3x more. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page; illustrative bands, not a quote for any particular company..)<br><br>Alliance Risk says entry-level management-liability packages that bundle D&O with EPLI and fiduciary often share a single aggregate limit, so a large EPLI or fiduciary settlement earlier in the policy year can reduce what is left for a later D&O claim; it says a specialist broker structures shared versus separate limits to manage that risk. [5](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: Management liability page's discussion of bundled D&O, EPLI and fiduciary programs..) | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Not publicly disclosed; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed..) |
| Risk Services | Alliance Risk offers a no-charge review of an existing D&O policy, identifying gaps in the Side A/B/C structure and missing endorsements and comparing the program to market options. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page, Get Your D&O Risk Review section..) | Aon says its brokerage and claims teams collaborate on coverage negotiations and describes insurer-selection analytics and a D&O Risk Analyzer. Those are broker services, not an insurer claim decision or guarantee. [8](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Company-reported brokerage and advisory services. Account-specific service terms are not stated..) |
| How to Apply | For a D&O quote, Alliance Risk asks for company revenue, industry and stage, board composition, investor structure, current D&O coverage and carrier, five-year claims history and upcoming events such as M&A or an IPO, and says it typically delivers proposals within a few business days. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Company-reported; scope: D&O product page, What We Need for Your Quote section; timing is a company estimate, not a guarantee..) | Confirm in your quote. |
| Claims Support | The reviewed D&O page does not describe an Alliance Risk claims-handling or claims-advocacy process; it discusses what a D&O policy covers rather than how Alliance Risk itself supports a claim. [4](https://joinalliancerisk.com/directors-officers-insurance-do/ "Directors & Officers Insurance (D&O)") (Evidence: Not found in reviewed sources; scope: D&O product page as read on 2026-09-23..) | Confirm in your quote. |

## Alliance Risk Reviews

Review Score: not enough ratings.

Alliance Risk has no customer ratings on the review sites we checked, so there's no Review Score yet. That says nothing bad about the company; it means you'll need to ask for references.
