Business Problem

Organizations globally are moving corporate email to the cloud, but the same cyber threats and data loss risks still exist in a cloud email deployment. Subsequently, there is requirement to enable the same level of security and protection as a traditional deployment. This can be delivered in different ways:

• Hosted: Where the email application is hosted in the cloud, but all administration is done by the organization.
• Managed: Where the email application is hosted in the cloud and the management of the services is carried out by a third party.

Architecture

The solution consists of deploying a Clearswift Secure Email Gateway in front of the cloud based email service, such as Microsoft Office 365. Requirements around scalability, availability and the number of users will determine the exact architecture. Clearswift has customers with more than 100,000 users of its Secure Email Gateway.

A number of records are needed to be changed to reflect the new security, these include: DNS records such as MX records, but could also include SPF, DKIM and DMARC records as well. The changes to records can be easily and quickly carried out.

In addition to the Secure Email Gateway managed service option, ARgon for Email can also be deployed as a managed service to enhance an existing email gateway with Adaptive Data Loss Prevention capabilities.

Deployment

Cloud based deployment requires a standard RHEL operating stack. This includes Microsoft Azure and Amazon’s AWS. Other more localized cloud providers can also be used. Clearswift will take care of the installation and upgrades across all platforms.

Compatibility with Microsoft Office 365

With organizations moving to Microsoft’s Office 365, it is good to know that you can take Clearswift security and data loss prevention technology with you. Clearswift Professional Services can migrate your Clearswift policy from an on-premise solution to a cloud based one.

By using Clearswift’s Adaptive Redaction options, organizations gain instant risk mitigation against sensitive data loss, Ransomware and other Advanced Persistent Threats (APTs).
