Cyber Insurance Requirements Are Tightening: What Your Architecture Needs to Prove

Cyber insurance applications have transformed from simple questionnaires into detailed technical audits. Insurers are no longer satisfied with a "yes" on a form — they want evidence. Some now conduct pre-binding technical assessments or require attestation from independent parties. If your architecture cannot prove compliance with insurer requirements, you face coverage denial, exclusions on critical scenarios, or premiums that make coverage uneconomical.

This guide maps the most common insurer requirements to Azure technical controls and shows you how to build continuous evidence collection.

The Insurer's Perspective

Understanding why insurers require specific controls helps you prioritise implementation. Insurers base their requirements on claims data. The controls they mandate are the ones whose absence correlates most strongly with successful attacks and large claims.

Top claim drivers in 2025-2026:

• Business email compromise (BEC) — often enabled by lack of phishing-resistant MFA
• Ransomware — typically exploiting unpatched vulnerabilities, weak remote access, or compromised privileged accounts
• Data exfiltration — enabled by inadequate logging and slow detection
• Supply chain compromise — enabled by insufficient third-party risk management

Every technical requirement an insurer imposes maps directly to one of these claim categories.

Requirements to Controls Overview

Mapping Requirements to Azure Controls

Requirement 1: MFA for All Users and Remote Access

What insurers ask:

• Is MFA enforced for all users accessing email and cloud applications?
• Is MFA enforced for all remote access (VPN, RDP, SSH)?
• Is MFA enforced for all administrative access?

Azure implementation:

Create three Conditional Access policies covering these scenarios:

All users — all cloud apps:

• Target: All users (exclude break-glass accounts only)
• Cloud apps: All cloud apps
• Grant: Require authentication strength — MFA

Remote access:

• Target: All users
• Conditions: Any location except trusted (corporate) locations
• Grant: Require authentication strength — Phishing-resistant MFA

Administrative access:

• Target: Directory roles (all admin roles)
• Cloud apps: All cloud apps
• Grant: Require authentication strength — Phishing-resistant MFA

Evidence collection:

• Export Conditional Access policy definitions (JSON) from Entra ID
• Pull the Entra ID sign-in logs showing MFA completion rates
• Generate the Authentication Methods Activity report showing registration coverage
• Screenshot the Conditional Access "What If" tool confirming enforcement for sample users

Requirement 2: Endpoint Detection and Response (EDR)

What insurers ask:

• Is EDR deployed on all endpoints (workstations, servers, mobile)?
• Are EDR alerts monitored 24/7?
• Is automated response enabled for high-confidence threats?

Azure implementation:

Deploy Microsoft Defender for Endpoint across all managed devices via Intune. For servers, enable Defender for Servers Plan 2 in Defender for Cloud.

Create an Azure Policy that audits EDR deployment:

{
  "if": {
    "allOf": [
      { "field": "type", "equals": "Microsoft.Compute/virtualMachines" },
      { "field": "Microsoft.Compute/virtualMachines/storageProfile.osDisk.osType", "equals": "Windows" }
    ]
  },
  "then": {
    "effect": "auditIfNotExists",
    "details": {
      "type": "Microsoft.Compute/virtualMachines/extensions",
      "existenceCondition": {
        "allOf": [
          { "field": "Microsoft.Compute/virtualMachines/extensions/type", "equals": "MDE.Windows" },
          { "field": "Microsoft.Compute/virtualMachines/extensions/provisioningState", "equals": "Succeeded" }
        ]
      }
    }
  }
}

Evidence collection:

• Defender for Cloud coverage report showing all subscriptions with Defender for Servers enabled
• Intune device compliance report showing Defender for Endpoint onboarding status
• Defender for Endpoint device inventory showing sensor health for all devices
• Sentinel incident log showing 24/7 alert triage activity

Requirement 3: Backup Testing and Isolation

What insurers ask:

• Are backups performed for all critical systems?
• Are backups tested regularly (restore tests)?
• Are backups isolated from the production network (air-gapped or immutable)?
• What is the recovery time objective and has it been validated?

Azure implementation:

Use Azure Backup with immutable vaults:

• Enable immutable vault property on all Recovery Services vaults — this prevents backup data from being deleted or modified, even by administrators
• Configure soft delete with a 14-day retention period as a minimum
• Enable multi-user authorization for critical backup operations (delete, reduce retention)
• Use cross-region restore for geo-redundant disaster recovery

For backup testing, build an automated monthly restore test:

1. Azure Automation runbook triggers a restore of the latest backup to an isolated resource group
2. Post-restore validation script checks data integrity and application health
3. Results are logged to a Log Analytics workspace
4. Restored resources are automatically cleaned up after validation

Evidence collection:

• Azure Backup reports showing backup success rates and compliance with policy
• Restore test logs from the automation runbook (dates, systems tested, results)
• Immutable vault configuration screenshots
• Recovery time measurements from actual restore tests

Requirement 4: Privileged Access Management

What insurers ask:

• Are privileged accounts managed separately from standard accounts?
• Is just-in-time access implemented for administrative roles?
• Are privileged access sessions monitored and recorded?
• How many users have standing Global Administrator access?

Azure implementation:

Deploy Entra ID Privileged Identity Management (PIM):

• Convert all standing admin role assignments to eligible assignments
• Set maximum activation duration to 8 hours
• Require justification and approval for Global Administrator activation
• Require phishing-resistant MFA at activation time
• Configure access reviews quarterly for all privileged roles

Maintain only 2 break-glass accounts with standing Global Administrator access.

Evidence collection:

• PIM role settings export showing eligible (not active) assignments
• PIM activation audit logs showing justification and approval workflow
• Access review completion reports
• Count of standing vs. eligible privileged role assignments

Requirement 5: Patch Management

What insurers ask:

• What is your patch cadence for critical vulnerabilities?
• What is your SLA for zero-day and actively exploited vulnerabilities?
• Do you have visibility into patch compliance across all systems?

Azure implementation:

Use Azure Update Management Center:

• Configure maintenance windows for regular patching (monthly for standard, weekly for critical)
• Set assessment schedule to daily for all VMs
• Create compliance reports showing patch status across the estate

Define patch SLAs:

Evidence collection:

• Azure Update Management compliance dashboard (export monthly)
• Patch cycle reports showing time-to-patch metrics
• Emergency patch records showing adherence to 48-hour SLA
• Azure Policy compliance showing patch assessment coverage

Requirement 6: Email Security

What insurers ask:

• Is email filtering deployed with anti-phishing capabilities?
• Are DMARC, DKIM, and SPF configured?
• Is user security awareness training conducted?

Azure implementation:

Deploy Microsoft Defender for Office 365 Plan 2:

• Configure anti-phishing policies with mailbox intelligence and impersonation protection
• Enable Safe Links with URL detonation
• Enable Safe Attachments with dynamic delivery
• Configure DMARC with p=reject policy (after monitoring period)
• Enable attack simulation training with monthly phishing simulations

Evidence collection:

• Defender for Office 365 threat protection status reports
• DMARC aggregate reports showing policy enforcement
• Attack simulation training completion rates and phish-prone percentages
• Email filtering statistics (blocked threats per month)

Requirement 7: Incident Response Plan

What insurers ask:

• Do you have a documented incident response plan?
• Has the plan been tested in the last 12 months?
• Do you have relationships with IR and forensics firms?

Azure implementation:

Document your IR plan and integrate it with Azure tooling:

• Sentinel playbooks that implement the automated response steps in your IR plan
• Pre-configured investigation workbooks for common incident types
• Documented escalation matrix with contact details
• Retainer agreement with an external IR firm (document the firm and contact details)

Conduct tabletop exercises twice per year and at least one technical exercise annually.

Evidence collection:

• Dated IR plan document with revision history
• Tabletop exercise reports with dates, participants, and findings
• Technical exercise after-action reports
• External IR retainer agreement (redacted if needed)

Building a Compliance Evidence Repository

Create a structured evidence repository that maps each insurer requirement to:

1. Control description — what you do
2. Azure service — which Azure service implements it
3. Evidence source — where to pull the evidence
4. Collection frequency — how often evidence is refreshed
5. Current status — compliant / non-compliant / partial

Automate evidence collection using Azure Workbooks and scheduled Logic App exports. Aim to have every piece of evidence refreshable within 24 hours of an insurer request.

Azure Policy Initiative for Insurance Compliance

Create a custom Azure Policy initiative that encodes your insurer's requirements:

{
  "properties": {
    "displayName": "Cyber Insurance Compliance Controls",
    "policyDefinitions": [
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[mfa-policy-id]" },
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[edr-policy-id]" },
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[backup-policy-id]" },
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[patch-policy-id]" },
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[encryption-policy-id]" },
      { "policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/[logging-policy-id]" }
    ]
  }
}

Assign this initiative at the management group level and review compliance weekly. Trending compliance scores over time demonstrate to insurers that you are not just compliant today — you maintain compliance continuously.

Common Mistakes

Answering "yes" without evidence. Insurers increasingly verify claims. If you state that MFA is enforced for all users but your Conditional Access policies have broad exclusions, you risk coverage denial post-claim.

Neglecting backup restore testing. Having backups is not sufficient. Insurers want evidence that you can actually restore from them. An untested backup is not a backup.

Standing privileged access. If 15 people have permanent Global Administrator access, your answer to "Is privileged access managed?" is effectively "no" regardless of what else you have in place.

Ignoring the renewal timeline. Evidence collection takes time. Start gathering evidence 60 days before your policy renewal, not 5 days before.

Conclusion

Cyber insurance requirements are a forcing function for security architecture improvement. Rather than viewing them as a burden, use them as a prioritised checklist of controls that materially reduce your risk. The controls insurers require are the same controls that prevent the most common and most expensive attacks.
