It’s hard to imagine getting work done without email. Every day, hundreds of messages fly in and out — project updates, financial reports, client notes, and everything in between. Email has become the heartbeat of enterprise communication: fast, convenient, and accessible from anywhere. But behind that convenience lies a big risk — email is still the easiest way for cybercriminals to break in. 

According to IBM’s 2025 Cost of a Data Breach Report, phishing is now the leading cause of data breaches, responsible for 16% of all incidents and costing organizations an average of USD 4.8 million per attack. It’s a clear reminder that every company needs a truly secure business email system to stay protected in today’s threat landscape. 

Wondering how to keep your company’s email both secure and efficient? Discover how Zimbra and Sophos combine enterprise-grade collaboration with powerful protection — helping you work smarter and safer. 

 

Why Business Email Is Still the #1 Target for Cyberattacks 

“Email is a huge cybersecurity threat — a single click on a malicious link can bring down an entire network.” 

— Kevin Mandia, CEO of Mandiant 

Even with the rise of modern communication platforms, email remains the primary channel for business communication. From customer data and invoices to confidential corporate files—everything flows through the inbox. For attackers, it’s the easiest “front door” to knock on. 

The reason is simple: email depends on human interaction, and humans are the hardest element to secure. That’s why organizations must see email not just as a communication tool, but as a critical part of their cybersecurity strategy.
