Email encryption that makes compliance easy

secure-email-gateway-transparent-encryptionEmail is a common source of data loss. With governments across the globe increasing the penalties for breaches, encryption is the best way to secure data sent by email and comply with data security regulations.

Like everything else we do at Sophos, we’ve made protecting your email simple.

Sophos UTM Email Protection and our Sophos Email Appliances include our cutting-edge SPX technology that simplifies encryption without slowing down your business.

Our patent-pending Secure PDF eXchange (SPX) email encryption offers a better alternative to traditional encryption solutions, which are often hard to manage and disruptive to your workflow.

Conventional certificate-based systems force you to invest in expensive and complex infrastructure. And webmail services redirect users to portals outside their domain to retrieve confidential information, often triggering suspicions of phishing.

Our unique, password-protected SPX Encryption gives you the security you need, without the drawbacks of other solutions.

  • Setup is simple—just activate the SPX Encryption option on your Sophos Email Appliance.
  • Easily define encryption policies using the policy wizard. Establish rules based on attributes including the presence of sensitive data (as determined by the DLP engine), sender, recipient, message content, attachments, message header, and more.
  • No client software installation required. SPX Encryption uses built-in, cross-platform PDF reader software.
  • Flexible password management options to fit the user experience you want, such as user registration, auto-generated, and web services integration.
  • Promote trust and familiarity for recipients with the flexible branding options, including customizable templates, cover pages and portal sites.

A seamless user experience

SPX Encryption provides the best user experience in the industry. Users can work with their email as they always have, without disruptive changes to workflow.

  • When a user receives an encrypted message, they simply open the encrypted PDF attachment and enter their password to view attachments.
  • Off-line viewing allows mobile workers to access their email when they don’t have an Internet connection.
  • SPX encrypted messages are supported on all popular smartphone platforms with native or third-party PDF file support, including iPhone, BlackBerry and Windows Mobile.
  • Secure reply capability is integrated into all encrypted messages, so recipients can send an encrypted response through the appliance without any encryption infrastructure.

Easier compliance

SPX Encryption with Sophos DLP simplifies compliance with internal or external data protection regulations and privacy guidelines. A point-and-click policy engine integrates with Microsoft Active Directory services, making policy administration simple and effective.

We’ve integrated SPX Encryption with Sophos UTM Email Protection and our Sophos Email Appliances. Deployment, administration, and support couldn’t be simpler.

How can off-site users get their Outlook email encrypted by the office based Sophos SPX enabled firewall? Is this possible?


Certainly, if the user utilizes a VPN connection to connect to the office network. Other methods might work depending how things are setup, but that’s the sure way. I would encourage you to head to the community forums for more info…



I have looked at this solution for a while – SPX – and nowhere in the Sophos blurb does it mention if this supports Office 365 – i.e. encryption for on pemises Outlook connecting to Exchange in the 365 cloud.

Could you let me know and them ammend your sales literature to make it clear if this is just for on premises email servers or not.
