Cyber insurance is no longer optional for small and mid-sized businesses—it’s a requirement for survival.

But here’s the problem:

Most SMBs think they’re “covered” because they have antivirus or backups… and then get denied or excluded from coverage when it actually matters.

At Secure SMB, we’ve seen it repeatedly.

Below are the 5 most common cybersecurity mistakes that will either:

• Get your policy denied
• Void your coverage
• Or leave you exposed when a breach happens

---

❌ 1. No Enforced Multi-Factor Authentication (MFA)

This is the fastest way to get denied.

Most insurers now require:

• MFA on email (Microsoft 365 / Google Workspace)
• MFA on remote access (VPN, RDP)
• MFA for admin accounts

The mistake:
➡️ MFA is “enabled”… but not enforced everywhere

What happens:
Attackers log in with stolen credentials → insurer denies claim

✅ What to do instead:

• Enforce MFA across ALL users (not optional)
• Lock down legacy authentication
• Protect privileged/admin accounts first

---

❌ 2. Thinking “Backups” = “Disaster Recovery”

Having backups is not enough anymore.

The mistake:
➡️ Files are backed up… but you can’t restore quickly when ransomware hits

What happens:

• Business downtime lasts days (or weeks)
• Clients lost
• Insurance questions your recovery capability

✅ What to do instead:

• Use backup + rapid recovery (BCDR)
• Test restores regularly
• Know your recovery time (RTO) and data loss window (RPO)

---

❌ 3. No Endpoint Protection Beyond Basic Antivirus

Basic antivirus is outdated.

The mistake:
➡️ Relying on legacy AV instead of modern endpoint protection

What happens:

• Zero-day threats slip through
• No visibility into suspicious behavior
• Claims may be denied due to “inadequate controls”

✅ What to do instead:

• Deploy advanced endpoint protection (EDR/MDR)
• Monitor for behavior, not just known threats
• Centralize alerts and response

---

❌ 4. Unsecured Email (Still the #1 Attack Vector)

Most breaches start with email.

The mistake:
➡️ No protection against phishing, spoofing, or account takeover

What happens:

• Fake invoices
• Credential theft
• Business email compromise (BEC)

✅ What to do instead:

• Enable phishing protection & email security layers
• Use DMARC, DKIM, and SPF properly configured
• Train employees to recognize threats

---

❌ 5. No Documented Security Policies or Proof of Controls

This is the silent killer in claims.

The mistake:
➡️ You have tools… but no documentation or proof they’re properly configured

What happens:

• Insurer asks for evidence after a breach
• You can’t prove controls were in place
• Claim is reduced or denied

✅ What to do instead:

• Document your security controls
• Track compliance with insurer requirements
• Regularly review and update policies

---

✅ What This Means for Your Business

Cyber insurance isn’t just about buying a policy anymore—it’s about proving you’re secure enough to qualify.

If even one of these areas is weak, you’re at risk of:

• Denied claims
• Reduced payouts
• Increased premiums

💡 Final Thought

Most SMBs don’t lose coverage because they were unlucky.

They lose coverage because they missed the fundamentals.
