What Can Clearswift Secure Email Gateway do for you?

Clearswift's Secure Email Gateway (SEG) not only protects against spam, viruses, and advanced threats including phishing, ransomware, and spyware, but layers on the next-gen Cloud Sandbox from Sophos. This offers machine learning to provide an additional layer of security for content or communications deemed suspicious.

The functionality of the Fortra Secure Email Gateway and its web-based interface have always been key strong points for us. The solution’s integration with Microsoft 365 was a real bonus. We now have peace of mind that our new cloud email platform has the same level of protection that we'd become accustomed to.

Key Features of Clearswift's Secure Email Gateway

Clearswift's SEG is mail system-agnostic, scalable from SMEs to enterprises, and complementary either to a cloud-based solution, such as Microsoft 365 and Google Workspace, or for on-premise systems like Microsoft Exchange.

Inbound threat protection

Using multiple Anti-virus Engines, the SEG 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.

Data Loss Prevention

Data Loss Prevention (DLP) is not just an outbound problem. Depending on your business, you might need to control the content of what’s being received by your employees.

It is imperative that a thorough understanding of the message is performed by the deep content inspection capabilities in order to understand the email body, subject lines, and attachments (such as PDFs, Word documents, and images). This way, they can be scanned for critical information like intellectual property, employee’s personal information, or forgotten content like metadata, revision history, or customer data.

Metadata can include document classification tags from Titus and Boldon James solutions which can signify whether the content is unclassified, classified, or even top secret.

The understanding of the content and the context is then applied into configured policies to determine if the message should be rejected, held, delivered, delivered encrypted, or sanitized in some way prior to delivery.

Sanitization can take the form of automatic redaction of text with message bodies and attachments including images (such as screen shots) using OCR technology, or document sanitization which can remove hidden metadata, revision information, and auto-saved data associated with documents and images.

The SEG enables compliance with regulations (GDPR, HIPAA, etc.) – detects, protects, and audits emails, and attachments to validate sensitive data. Then it applies the appropriate security remediation according to the specific regulation standards.

Safe Delivery

Encryption provides security and regulatory compliance needed to keep data secure. Multiple encryption options provide many ways to secure email content by verifying that messages cannot be read by the wrong recipients, and the message stays intact - not modified by anyone from sender to recipient.

The SEG encryption options allow policies to be based on sender, recipient, subject content, message body, attachment types, attachment content, message header or document metadata. Using encryption guarantees confidentiality, integrity, and availability of organizational data.

Unparalleled Deep Content Inspection

A Deep Content Inspection Engine detects and analyzes the content of incoming and outgoing emails down to 50 levels.

Game-Changing Adaptive Redaction

Sensitive data is automatically removed from documents and images. Text in images is identified using Optical Character Recognition (OCR).
Metadata, change history and properties are removed from files, including content embedded in images using steganography tools.
URLs are rewritten before they cause harm and active code (macros, scripts and Active/X) is removed from Microsoft Office, Open Office, and PDF files.

Multi-Layered Spam Defences

Dual anti-spam engines reduce the amount of spam reaching the end user and the number of false positives.

Outbound Data Loss

Powerful lexical analysis and regular expression rules search messages and content for key words and phrases. When policy violations are found, sensitive data can be automatically removed, or managed by System Administrators or Line Managers.
