Email is a major attack surface for organizations, exploited through methods like ransomware and phishing. IBM’s 2024 report highlights a 15% increase in data breach costs, underscoring the importance of robust email security. Effective solutions prevent malicious emails from reaching inboxes without disrupting legitimate communication. Free email services like Gmail and Yahoo have spam folders but can’t stop all threats.

The Need for Email Security

Effective email security stops harmful messages from entering the inbox without disrupting legitimate communications. Small businesses receive hundreds of emails daily, while large enterprises handle thousands, all needing screening for malicious content. Free email services like Gmail and Yahoo have spam folders but cannot block all threats.
