How It Works


Secure Email Gateway


Advanced Protection

Protect your users from the latest identity theft, password and banking scams, and other incidents. Keep users productive by intercepting all emails containing suspicious content, attachments, or URLs.

We employ the latest antivirus and phishing detection technology that constantly updates in real-time to detect the latest threats. We also block unwanted content using MIME type and extension filters.

Sophos Sandstorm

Effective Anti-Spam

Keep your inboxes free of spam and phishing attacks.

  • Reputation filtering blocks 90% of spam at the gateway, before it consumes any of your network resources
  • An anti-spam engine catches the rest, including the latest phishing attacks
  • Filters incoming email using a variety of advanced detection methods, across dozens of languages

Transparent DLP and Encryption

Encrypt and digitally sign your sensitive email automatically and transparently. Stop inadvertent data leakage and make compliance easy with our advanced DLP and policy-driven encryption.

Message bodies and attachments are automatically scanned for sensitive data. You can easily establish policies that determine if those emails are blocked or encrypted with just a few clicks. Alternatively, give users the option to encrypt emails themselves with our Outlook plugin.

The best part: our unique patent-pending SPX Encryption allows users to manage their encrypted mail in their preferred email client. Online, offline, desktop, or mobile – it doesn’t matter. Email encryption has never been simpler for users or administrators.

Simple Management

At Sophos, simplicity is our mantra. You’ll have complete control over all the security features you need all in one place, with none of the complexity.

We've invested heavily in streamlining our interface. This way you won't have to reach for the manual every time you need to update a policy or change a setting, so you're never more than a couple clicks from completing your task.

Complete On-Box Reporting

Our built-in reporting means you’ll know exactly what's happening with your users. Fix problems fast and shape your policies, keeping your users secure while boosting network performance. Plus, you get detailed reports as standard, stored locally with no separate tools required.

At-a-glance flow graphs show usage trends with predefined and customizable reports, providing key web activity. Anonymized reports hide user names, requiring the four-eyes-principle to unhide them.
