Why Email Server Security is Crucial in 2025

According to the Verizon Data Breach Investigations Report, over 90% of cyberattacks start with a phishing email. With the rise of remote work and cloud-based collaboration tools, email systems have become more exposed than ever before.

Top threats to email servers today:

Ransomware: Often delivered via infected attachments or links
Business Email Compromise (BEC): Sophisticated social engineering attacks targeting executives
Data leaks: Sensitive information sent without encryption or filtering
Spam overload: Costing companies time, bandwidth, and productivity

Additionally, regulations like GDPR, HIPAA, and PCI-DSS demand strict control over how email communications are secured. Failure to comply could result in hefty penalties.
