Coalition and At-Bay are the two names that come up first in modern cyber insurance, and for the same reason: both decided the policy shouldn't just pay for a breach — it should help prevent one. But they draw the line between insurance and security in different places. Here's how they actually compare.
This is an independent comparison from QuoteSweep, which maps the modern commercial insurance landscape. QuoteSweep does not compete with either company.
TL;DR: Both bundle cyber coverage with security services and sell through brokers. Coalition carries the broader product set (cyber, technology E&O, executive risks, MPL, and AI-threat coverage) on a large panel of A-rated capacity, with the deepest security platform. At-Bay leans hardest into bundled managed detection & response, packaged in tiers, on A++ rated capacity tied to Munich Re. Choose Coalition for breadth and platform; choose At-Bay for MDR built into the policy.
The one-line difference
- Coalition calls its model Active Insurance — coverage plus a security platform (Coalition Control, Wirespeed MDR, monitoring, and alerts) — and sells a wide range of lines beyond cyber.
- At-Bay calls its model InsurSec — insurance plus security — and packages managed detection & response into three coverage tiers, staying focused on cyber and adjacent professional lines.
Model and security bundle
Both give every policyholder security tooling, not just a policy.
- Coalition: the Coalition Control® risk platform, continuous vulnerability and dark-web monitoring, AI-powered email-fraud alerts, and Wirespeed MDR with 60+ integrations. When something breaks, Coalition Incident Response brings in digital-forensics expertise.
- At-Bay: a tiered bundle — Core (vulnerability monitoring, vCISO advisory, email-fraud security, awareness training), Advanced (adds MDR for endpoints, 24/7), and Complete (adds MDR for email). Everything sits in one dashboard.
The practical distinction: At-Bay makes the level of managed detection an explicit, tiered choice; Coalition folds a broad platform in and layers MDR through Wirespeed.
Coverage lines
| Coalition | At-Bay | |
|---|---|---|
| Cyber | ✓ (SME + enterprise) | ✓ |
| Technology E&O | ✓ | ✓ |
| Miscellaneous Professional Liability | ✓ | ✓ |
| Executive Risks (management liability) | ✓ | — |
| AI-threat coverage | ✓ | — |
Coalition's product set is wider — it can cover management liability and AI-specific threats that At-Bay's cyber-focused lineup does not.
Capacity and distribution
- Coalition: underwrites on a large panel — Allianz (A+), Arch, Ascot, Fortegra, Lloyd's, Swiss Re, Vantage, Zurich, and others. Broker-distributed.
- At-Bay: an insurance agency and surplus-lines broker licensed in all 50 states, writing on A++ (Superior) rated capacity tied to Munich Re's HSB. Broker-distributed, with a Broker Platform that quotes and binds in minutes.
Neither sells direct to most businesses, and neither publishes flat pricing — you go through a broker either way.
Funding and scale
- Coalition: per reporting, a $250M Series F at a $5B valuation in 2022 (led by Allianz X); roughly $800M+ raised in total. It is the category leader by policy count.
- At-Bay: per reporting, a $185M Series D at a $1.35B valuation in 2021 (co-led by Icon Ventures and Lightspeed); ~$296M total, with 40,000+ policyholders.
Both valuations are from earlier rounds, not fresh 2026 marks — read them as scale signals, not current prices.
Who each one fits
- Choose Coalition if you want breadth (cyber plus executive risks, MPL, and AI coverage) and the deepest bundled security platform, and you value the largest capacity panel.
- Choose At-Bay if you're a tech or mid-market company whose priority is real managed detection & response built into the policy, and you want to pick your security tier explicitly.
For most buyers the deciding factors are which lines you need (only Coalition writes executive risks and AI-threat coverage) and how much managed security you want bundled in. Your broker can quote both.
Frequently Asked Questions
Are Coalition and At-Bay carriers or brokers?
Both are cyber-focused managing general agents/underwriters that write on A-rated capacity partners and distribute through appointed brokers, rather than selling direct or carrying the risk on their own balance sheet.
What's the core difference between them?
Product breadth and security emphasis. Coalition writes a wider set of lines (including executive risks and AI-threat coverage) with a broad security platform; At-Bay stays focused on cyber and professional lines and leans hardest into tiered managed detection & response.
Which is cheaper?
Neither publishes flat pricing; premium depends on your business, security posture, and coverage. Compare quotes for the same limits through a broker.
Where can I compare more cyber insurers?

The bottom line
Coalition and At-Bay agree on the big idea — insurance should reduce risk, not just pay for it — and differ on execution. Coalition is the broader, platform-first leader; At-Bay is the MDR-first specialist. Match the choice to the lines you need and the amount of managed security you want in the policy.
