⚠️ Common Mistakes to Avoid
🚫 Coverage Coordination Pitfalls
❌ Assuming cyber insurance covers all technology risks
Software errors that aren't caused by cyberattacks need E&O coverage
❌ Buying from different carriers without coordination
Creates potential coverage gaps and claim coordination issues
❌ Mismatched policy limits
$5M cyber coverage with $1M E&O creates unbalanced protection
❌ Not disclosing one policy to the other carrier
Can void coverage for failure to disclose other insurance
❌ Different policy periods
Creates coverage gaps when policies renew at different times
🎯 The Bottom Line
Cyber insurance and E&O insurance protect against different types of business risks. Most professional service businesses need both—cyber insurance for criminal attacks, E&O insurance for professional mistakes. The key is coordinating coverage to avoid gaps while maximizing value through package discounts.
