Email remains the primary communication tool for businesses of all sizes. Unfortunately, threat actors are experts at evading secure email gateways, making email the most exploited entry point for cybercriminals. Recent history is littered with examples of devastating attacks that started with a seemingly innocuous email. Consider these incidents from just the past year:

• Office of the Comptroller of the Currency (OCC) Email Espionage (ending early 2025): For over a year, hackers infiltrated the email accounts of more than 100 U.S. bank regulators at the OCC, gaining access to approximately 150,000 sensitive emails.
• Orion BEC Attack ($60 million loss - August 2024): The chemical manufacturing firm Orion suffered a staggering $60 million loss due to a Business Email Compromise (BEC) attack.
• Ongoing Russian Phishing Campaigns Targeting Ukraine (2024-2025): Throughout the ongoing conflict, Russian state-sponsored actors have relentlessly used advanced phishing campaigns as a primary method to infiltrate Ukrainian government and military networks.

These incidents are stark reminders that traditional email defenses are often insufficient against the ever-evolving tactics of cybercriminals. Protecting your organization starts with robust email security. Here's why MailMarshal is the comprehensive email security service you need:

1. Proven, Layered Protection

MailMarshal has protected email systems for over 20 years without a major breach. It uses advanced, multi-layered email protection backed by Trustwave SpiderLabs – a global team of 150+ security researchers who constantly update MailMarshal to defend against the latest threats.

2. Strong Defense Against Email Attacks

MailMarshal, as a leading secure email gateway, helps stop phishing, ransomware, and malicious links or attachments before users even open them. Built-in warnings and optional encryption keep users protected without slowing them down.

3. Adds Muscle to Microsoft 365

Microsoft 365 only handles basic threats. MailMarshal fills the gaps by adding stronger email protection and works seamlessly with Microsoft’s E1, E3, and E5 plans – and other email platforms too.

4. Supports Global Data Privacy

With both on-prem and hybrid cloud options, you control where your email data lives. MailMarshal Cloud supports data sovereignty laws (like GDPR) with hosting in the U.S., UK, EU, and Australia.

5. Built-In Data Loss Prevention (DLP)

MailMarshal scans outgoing emails and attachments to prevent accidental or intentional sharing of sensitive data. You can set rules to block risky messages – like someone trying to send a customer list.

6. Stops Blended Threats

Some attacks use a mix of email and malicious websites. MailMarshal’s blended threat module analyzes links in real time, blocking harmful content before users can access it – from any device, anywhere.

7. Flexible Deployment Options

Choose from cloud-based, on-premise, or hybrid setups – whatever fits your environment. MailMarshal adapts to your email infrastructure.

8. Easy to Set Up and Manage

The on-prem version installs in minutes with a setup wizard. The cloud version requires no install – just update your MX record. Both offer a simple control panel and 130+ pre-built rule sets.

9. Expert Help Available

Need help with setup, design, or policy rules? Trustwave’s Consulting & Professional Services (CPS) team is ready to assist at any level.

10. Solves Cloud Email Limitations

Email systems like Microsoft 365 struggle with certain automated messages – like those from helpdesks or billing systems. MailMarshal handles them all in one portal with full policy and compliance control.

11. Secure Email for Sensitive Info

With an optional add-on, users can safely send confidential emails and documents without making the recipient download anything. It’s simple, secure, and global.
