For insurance companies, email remains one of the most critical—and vulnerable—business communication channels. Claims documents, underwriting reports, policy renewals, financial records, customer information, and regulatory correspondence all move through corporate email systems every day.
Unfortunately, email is also the primary entry point for cyberattacks. Phishing campaigns, business email compromise (BEC), ransomware, credential theft, and account takeover attacks continue to target insurers because of the high value of the financial and personal information they manage.
To reduce these risks, many insurance providers evaluate Proofpoint and Mimecast, two of the most widely adopted enterprise email security platforms. Both solutions provide advanced protection beyond standard spam filtering, including threat detection, URL analysis, attachment sandboxing, impersonation protection, and user awareness capabilities.
While security effectiveness is essential, insurance organizations must also consider licensing costs, implementation effort, regulatory obligations, operational efficiency, and long-term scalability. This guide compares Proofpoint and Mimecast with a focus on the budgeting considerations that matter most to insurers.
Why Insurance Companies Require Advanced Email Security
Insurance businesses process large volumes of confidential information across multiple departments and communication channels.
Common email users include:
- Claims adjusters
- Underwriters
- Brokers
- Customer service teams
- Finance departments
- Legal teams
- Compliance officers
- Executives
- Third-party partners
A successful phishing attack against any of these users can expose sensitive customer records, disrupt operations, or result in financial fraud.
Modern email security platforms help reduce these risks by identifying malicious messages before they reach employee inboxes.
