Key Benefits of Secure Email Gateway

To reduce the chances of accidental data loss, the Secure Email Gateway controls messages based on the policies set by your organization and the content in the email communication. Granular policy control enables you to set policies for an individual, group (department or level of security clearance), or the whole organization.

The email body, subject lines, and attachments (such as PDFs, word documents, images) are all scanned for critical information like intellectual property, employee’s personal information or customer data with the optimal security treatment applied in real-time protecting your organization from financial loss and reputational damage.

With the choice of three cloud-assisted anti-virus engines, stop known and unknown malware infections with bi-directional scanning. In additional to the anti-malware features, protect against targeted attacks like ransomware, spyware and phishing by removing suspicious scripts, macros, URLs or HTML from communications.

Our deep content inspection engine can fully disassemble the communication flow in real time, providing a complete understanding of the critical information being shared both in and out of your organization. This solution is not limited by file size, zip/encryption, or multiple embedded document layers and provides high detection rates, which keeps data secure and keeps business operating.

Clearswift’s unique adaptive redaction technology modifies content in real-time making email communication and attachments safe per your organization’s security policies. Forgotten content like meta-data, revision history, properties and other hidden and unchecked information can be blocked or removed to protect your sensitive information from being exposed without disrupting the flow of communication.

Regulations like HITECH in the US and the GDPR in the EU require that sensitive data must be encrypted when sent via email. Supporting several different encryption options, TLS as standard with options for S/MIME and PGP, the Secure Email Gateway provides the flexibility required to provide the optimal format for the recipient.

The user interface of the Secure Email Gateway is powerful, yet simple to use. With roles-based access control and active directory authentication, automation and policy re-use, it’s quick and easy to build policy, manage violations, track messages and report on trends and behavior. This all contributes valuable insight without consuming valuable admin resource.

To help ensure you maintain compliance, included with Clearswift’s Secure Email Gateway are ready-to-use policies for regulations like HIPAA, GDPR, and SOX. Organizations that must adhere to PCI or PII standards can utilize the custom dictionary and any of the 200+ pre-configured tokens to simplify policy definition and enforcement.
