You are reading Part 5 of our 12-part Insurance Agency Authority Series.
A modern cybersecurity stack for an insurance agency should protect five layers: devices, users, identities, cloud applications, and business data. For an agency with 15 to 30 employees, the stack should include antivirus, Endpoint Detection and Response, email filtering, security awareness training, Microsoft 365 management, backup, monitoring, patching, documentation, and incident response procedures. Some agencies also need Business Continuity and Disaster Recovery, penetration testing, or compliance management. No single product provides complete protection. The stack must be layered, monitored, maintained, and aligned with the agency’s actual risks.
The 5-Layer Insurance Agency Security Stack
A complete security strategy should address:
- Device protection
- User and email protection
- Identity and cloud protection
- Data protection and recovery
- Monitoring, documentation, and response
Each layer addresses a different attack path.
Layer 1 – Device Protection
Every managed workstation and server should have:
- Antivirus
- Endpoint Detection and Response
- Patch management
- Remote monitoring
- Device backup where applicable
- Standard security configurations
- Local administrator controls
Traditional antivirus looks for known threats. EDR adds behavioral monitoring and can help identify suspicious activity that traditional antivirus may miss.
Device protection should be verified continuously.
The agency should know:
- How many devices are managed
- Which devices are missing tools
- Whether agents are reporting
- Whether critical patches succeeded
- Whether unsupported systems remain
- Whether security alerts were investigated
An unmanaged laptop can create an entry point into the broader environment.
Layer 2 – User and Email Protection
Users are frequently the primary target.
Insurance employees regularly receive messages involving:
- Policy renewals
- Client attachments
- Claims information
- Vendor invoices
- Carrier communications
- Banking details
- Password resets
- Document signatures
Attackers imitate these normal workflows.
User and email security may include:
- Inky email protection
- Spam filtering
- Phishing detection
- Link and attachment inspection
- BullPhish ID awareness training
- Phishing simulations
- Dark Web ID monitoring
- Reporting procedures
- Executive impersonation protection
Training should be ongoing. A single annual video may not be enough to change behavior.
Layer 3 – Identity and Cloud Protection
Microsoft 365 and other cloud platforms should be protected with:
- Multi-factor authentication
- Conditional access
- Administrative account separation
- Secure password practices
- SaaS Alerts
- Login monitoring
- External sharing controls
- User lifecycle management
- Microsoft 365 maintenance
