Why Insurers Are Denying Claims: The Security Controls You Must Have

Dental practices are discovering a harsh truth: the cyber insurance they've been paying for won't pay out when they need it most. Not because of fine print, but because they failed to implement the basic security controls their policies explicitly required as conditions of coverage.

Cyber insurance isn't like building insurance where coverage is automatic after a fire. It's conditional coverage that requires you to maintain specific security measures. Fail to implement those measures, and insurers will deny your claim—leaving you responsible for the full cost despite years of premium payments.

The Coverage-Denial Trend

After years of increasing claims from healthcare breaches, insurers are scrutinizing security practices before paying claims, sending forensic investigators to verify what controls were actually in place, and denying claims at increasing rates when they discover practices failed to maintain required protections.

Courts are consistently ruling that when a policy explicitly requires specific security measures, failing to implement them voids coverage.

The "Must Have" Security Controls

Multi-Factor Authentication (MFA): Required for all remote access, email, cloud services, and administrative accounts. Visit CISA's MFA guidance for implementation best practices. Common gap: MFA on some systems but not all. Any gap can void coverage.

Endpoint Detection and Response (EDR): Advanced security software on all computers and servers. Traditional antivirus isn't sufficient. Common gap: EDR on most systems but missing from remote workers or legacy servers.

Regular, Tested Backups: Daily backups with offline storage, tested quarterly. Follow CISA's ransomware guide for backup best practices. Common gap: Backups exist but aren't tested, or backup systems get encrypted during attacks.

Vulnerability and Patch Management: Continuous scanning with timely remediation of critical vulnerabilities. CISA's BOD 22-01 mandates 72-hour remediation for Known Exploitable Vulnerabilities. Common gap: Quarterly scans with patches applied during "convenient" maintenance windows.

Email Security: Advanced threat protection beyond basic spam filtering, including defenses against account takeovers, impersonation attacks, and AI-generated phishing that legacy filters simply weren't built to catch. Today's attackers use AI to craft convincing emails that bypass traditional detection — making AI-based email security tools an essential layer of protection. Common gap: Relying on basic spam filtering alone, leaving practices exposed to the sophisticated social engineering tactics most frequently used to compromise healthcare organizations.

Security Awareness Training: Annual training for all staff with simulated phishing tests. Common gap: Training completed once years ago, never refreshed, with no testing.

Logging and Monitoring: 24/7/365 SOC or MSSP monitoring of security events. Reference NIST SP 800-92 for logging guidelines. Common gap: Logs collected but only reviewed reactively when problems are reported.

Incident Response Plan: Documented, tested plan with annual tabletop exercises. Use NIST SP 800-61 as a framework. Common gap: Plan exists on paper but has never been tested.

The Application vs. Reality Gap

Practices answer insurance applications based on what they believe is in place. Then breach investigations reveal the gaps:

You reported: "MFA enabled on all remote access." Reality: MFA on VPN but not on remote desktop or cloud services.

You reported: "EDR deployed across all endpoints." Reality: EDR on 85% of workstations, missing from remote workers.

These gaps become material misrepresentation that insurers use to deny claims.

What "Compliance" Actually Means

Simply having these tools isn't enough—they must be properly implemented, configured, and actively used. MFA isn't compliant if users can skip it. EDR isn't compliant if alerts are ignored. Backups aren't compliant if they haven't been tested. Training isn't compliant if simulated phishing shows staff still clicking malicious links.

Making Sure You're Actually Covered

Review your policy requirements in detail. Verify current implementation for each required control using the NIST Cybersecurity Framework as a guide. Document everything proving compliance. Fill gaps immediately. Consider MSSP partnership to maintain required controls. Compare your application answers against current reality.

The Bottom Line

These requirements aren't arbitrary—they're the proven controls that prevent or contain breaches. Implementing them isn't just about satisfying your insurer; it's about actually protecting your practice.

The question isn't "do we have cyber insurance?" It's "if we had a breach tomorrow and our insurer investigated, would they find that we met all policy requirements?"

If the answer is no—or if you're not certain—you're at risk of paying for insurance that won't cover you when you need it most.

Unsure whether your practice meets cyber insurance requirements? Black Talon Security provides comprehensive security assessments that identify gaps in your insurance compliance while implementing the controls that both satisfy insurers and actually protect your organization.
