Secure Email Gateway

Protect against inbound email cyberattacks and outbound data loss prevention 

As the number one method of communication for most organizations, email has become one of the top sources for cybercriminals to infiltrate your systems and take hold of your critical data. Clearswift's Secure Email Gateway protects against spam, viruses, and advanced threats including phishing, ransomware, and spyware. Layering on the next-gen Cloud Sandbox from Sophos offers machine learning to provide an additional layer of security for content or communications deemed suspicious.

IT teams need to ensure that information being shared across email both inside and out of the organization is not only secure, but appropriate and compliant. Clearswift’s unparalleled level of inspection and granular policy controls apply the optimal security treatment to your emails in real time reducing the risk of data loss. This keeps your communications safe and flowing, without business disruptions. 

Deployment Options

  • Managed or hosted in ISO-certified data centers
  • Public cloud deployment on Microsoft, Azure, or Amazon Web Services
  • Private cloud virtual environment running VMware/Hyper V
  • Own or packaged hardware

Requirements for Deployment

A standard RHEL operating stack is required, which includes Microsoft Azure, Amazon’s AWS, or localized cloud providers. Clearswift will take care of the installation and upgrades across all platforms.

Key Features of the Secure Email Gateway

Clearswift's Secure Email Gateway is mail-system agnostic, scaling from SME to Enterprises, complementing cloud-based solutions such as Office 365 and Google Workspace, or for on-premise systems such Exchange.

Inbound threat protection

Using multiple Antivirus Engines, the Secure Email Gateway provides inbound threat protection using traditional signature, heuristic, and cloud assisted lookups to deliver protection against malware, ransomware, and spyware.

Augment the AV engines with Active Code detection and an Active Code removal option or a cloud-based Sandbox to detonate the file to ensure no Zero-day threats get through.

Malicious URLs in messages and attachments can be checked using several threat feeds, which can cause the message to be blocked, the URL to be sanitized, or the URL be rewritten so that if the link is clicked the URL will be processed by a Browser Isolation solution.

Spam and phishing emails are dealt with by a multi-engine, multi-layered spam filtration system, incorporating Signature Engines with machine learning, DMARC, DKIM, SPF, IP Reputation, Greylisting and URL analysis. This provides a highly accurate and flexible approach where messages can be blocked, held, or delivered with warnings — all based on policy.
