EDR EVIDENCE GUIDE
EDR Deployment Checklist
Map your endpoint detection and response coverage by asset type. Get deployment evidence requirements and carrier alignment for Hartford, Coalition, Beazley, and Travelers.
What this cyber insurance requirement is
Endpoint detection and response (EDR) deployment for cyber insurance means installing and actively monitoring EDR agents across all managed endpoints — workstations, servers, and laptops. Carriers want to see coverage percentages by asset type, confirmation that the EDR solution includes managed detection and response (MDR) or SOC monitoring, and evidence that agents are actively reporting. Most carriers treat EDR as a baseline control and will flag gaps in coverage during underwriting.
Create your EDR deployment checklist below
What you'll get
- EDR Coverage Matrix by asset type (Windows, macOS, Linux, mobile)
- Deployment Evidence Checklist (dashboard screenshot, agent versions, MDR agreement)
- MDR/SOC Evidence requirements and ownership map
- Carrier alignment (what carriers care about & what this doesn't prove)
What carriers are looking for
Each carrier asks slightly different questions. Here are some named artifacts by carrier.
Hartford
- Endpoint protection (EDR/MDR) across managed infrastructure
- Coverage matrix and agent status
Coalition
- EDR deployment across all managed infrastructure
- Agent coverage report and deployment timeline
Beazley
- Endpoint detection and response capability
- Coverage by asset type and MDR service documentation
Travelers
- Intrusion detection and response capability
- Alert review logs and evidence of 24/7 or business hours SOC monitoring
What to collect
Evidence artifacts your broker will need during the renewal process.
EDR dashboard screenshot
Show agent status (version, last check-in), deployment date, and coverage count.
Agent version report
Export device list with agent versions, OS, last seen date. Identifies stale/unmanaged devices.
MDR agreement
Service contract or SLA with managed vendor or internal SOC. Shows alert response commitment.
Alert review logs
Sample of escalation or closure records. Proves ongoing monitoring and incident response.
Coverage by OS report
Breakdown of agent deployment by operating system (Windows, macOS, Linux, etc.).
Detection activity log
Recent detections or suspicious activity. Shows tool is active and detecting issues.
Important: What this doesn't prove
Be upfront about these gaps. Carriers appreciate honesty over overstatement.
Agents functioning: Screenshot only proves agents installed, not that they're detecting threats or functioning correctly.
Timely review: Alert logs don't prove alerts are reviewed within SLA or investigated thoroughly.
Universal coverage: Coverage report doesn't prove all in-scope devices are managed (e.g., BYOD, contractors).
Vendor SLA: MDR contract doesn't prove vendor is actively responding or escalating appropriately.
Who owns what
Provides hardware/asset inventory, operating systems in use, list of contractors/remote workers. Responsible for agent deployment across all in-scope devices.
Owns agent deployment, version management, alert monitoring (or coordination with MDR vendor). Provides dashboard screenshots, coverage reports, alert logs.
Coordinates evidence collection from insured and MSP. Maps coverage to carrier questions. Ensures checklist is complete before submission.
Frequently Asked Questions
Do we need to cover contractors and BYOD devices?
Carriers expect coverage of all endpoints accessing company data. This includes contractor laptops and sometimes BYOD. The checklist should clearly state what's excluded and why (e.g., "Customer devices not covered; customers sign acceptable-use policy instead").
Is CrowdStrike vs SentinelOne vs Microsoft Defender a factor?
Carriers don't usually mandate vendor, but they do care about deployment completeness and MDR backing. Some prefer enterprise-grade EDR (CrowdStrike, SentinelOne) over built-in solutions. Best practice: pair any EDR with an active SOC or managed MDR service.
What if agents are installed but outdated?
Carriers will flag this as a gap. Your agent version report should show current versions deployed across 95%+ of devices. If you have stale agents, that's a remediation item before renewal.
Do we need 24/7 SOC or can we do business-hours monitoring?
Depends on your company's risk profile and carrier appetite. 24/7 is better, but business-hours + escalation procedures can work if documented. Critical systems should trigger out-of-hours alerts regardless.
How does this fit into the renewal timeline?
Collect this evidence 90+ days before renewal. If gaps exist (e.g., missing OS coverage, outdated agents), remediate immediately. By the time the carrier asks, your checklist should be straight-through.
Can I use this checklist across multiple carriers?
Yes. This evidence covers the common denominator for Hartford, Coalition, Beazley, and Travelers. You may need to supplement with carrier-specific questions (e.g., Beazley's endpoint detection SLA), but the core checklist is portable.
