Are You Uninsurable? The 2026 Cyber Insurance Readiness Checklist

The Hard Truth: In 2026, insurance carriers have moved from "trust" to "verification." According to recent industry audits, over 80% of denied cyber insurance claims share one common factor: a failure to fully implement the security controls promised on the initial application.

Take a look at the below insurance assessment. Are any of these required by your cyber insurance? There many be more requirements hidden in your policy. Are you prepared for a cyber security incident?


1. Identity: The New Perimeter

  • [ ] Phishing-Resistant MFA: Multi-Factor Authentication is no longer optional. For 2026, many carriers specifically require Phishing-Resistant MFA (like FIDO2 or Hardware Keys) for all administrative and remote access.

  • [ ] Service Account Lockdown: Non-human accounts (printers, scanners, cloud connectors) must be restricted to "Least Privilege" access.

2. Defense: Beyond Antivirus

  • [ ] EDR/MDR Deployment: 65% of insurers now mandate Endpoint Detection & Response (EDR). Traditional antivirus is reactive; EDR is proactive and identifies "live" movements within your network. [Source: AllCovered 2026 Insurance Trends]

  • [ ] 24/7 Monitoring: For high-risk industries (Medical/Legal), carriers often require human-led Managed Detection & Response (MDR) to stop attacks at 3:00 AM on a Sunday.

    • The Fact: AI-driven attacks have slashed the average "breakout time" (the time it takes a hacker to move from your email to your server) to just 48 minutes. [Source: CrowdStrike 2025 Global Threat Report]

3. Filtering: Screen the Gateway

  • [ ] Phishing Protection: Email is often a hacker’s gateway to your sensitive data. Strong email security protects against unauthorized access, phishing, spam and malware attacks.

4. Resilience: Protection from Ransomware

  • [ ] Immutable/Air-Gapped Backups: If your backups are connected to your main network, they will be encrypted by ransomware. Carriers now require "Immutable" backups that cannot be modified or deleted.

    • The Fact: 96% of ransomware attacks now actively target backup repositories to force a payout. [Source: Enterprise Strategy Group (ESG)]

  • [ ] Proof of Restore: You must be able to provide logs showing a successful data restoration test within the last 90 days.

5. Human Firewall: Training your Team

  • [ ] Security Awareness Training (SAT): 81% of insurers now require proof of annual employee training.

  • [ ] Monthly Phishing Sims: Carriers look for reporting that shows your "Phish-prone percentage" is decreasing over time. [Source: PhishingBox Industry Insights]

The Ohio Advantage: "Safe Harbor"
