Email Security Solutions

As enterprise email security threats continue to evolve and become more sophisticated, your employees’ inboxes also become more vulnerable. According to Gartner, email is the most commonly used channel for cyber-attacks as well as a significant point of egress for sensitive content. And with the average cost of a data breach now at almost $4 million, securing your email communications with the right solution has never been more important.

You need robust protection from a wide range of email-based threats – malware, ransomware, phishing, business email compromise (BEC), spam, and data loss. You also need to balance security with the need to continuously collaborate. Any delays to email communications can be costly and frustrating.

Clearswift’s Email Security Solutions offer a unique and effective layer of real-time, signature-less inspection to detect and sanitize evasive threats, delivering highly secure email without delays. Whether deployed on-premise on in the cloud, working alone or alongside cloud-based email applications such as Office 365, Clearswift’s Secure Email Gateway keeps your organization’s email well protected.

Superior anti-malware protection is provided through Avira or Sophos anti-virus software engines that update signatures every fifteen minutes. Heuristics and behavioural analysis enhance detection capability even if no signature is present, preventing any known or unknown malware from entering or leaving the network.

For maximum defense against embedded Advanced Persistent Threats (APTs), these technologies are supplemented with the real-time sanitization of any active content within email messages or attachments, including the detection and removal of scripts, macros and objects from common Office 365 files and PDFs. Protection against attachment-based advanced threats is recommended in the Gartner Market Guide for Email Security.

Ransomware is often released by unsuspecting employees who click on a malicious URL within a phishing email. To neutralize this threat, the Secure Email Gateway uses a real-time URL look-up tool to rewrite or sanitize confirmed or suspicious URLs.
 

The threat of data loss through email is a major compliance concern for organizations. Recent statistics show that 24% of all data breaches are the result of human error, while 34% involved internal actors. Secure Email Gateways can protect against accidental or malicious data leaks by automatically inspecting outgoing email messages and attachments for any sensitive data.

Clearswift’s Email Security solutions use powerful lexical analysis and regular expression rules to search for key words and phrases and when found, the sensitive data can be automatically removed or managed by a system administrator or line manager. To mitigate the risk of data loss through images and scanned documents, Optical Character Recognition (OCR) technology allows the solution to redact sensitive data from images and scanned documents. It also inspects incoming emails and attachments to ensure the threat of any unwanted data acquisition is removed.

As part of the content inspection process, the Clearswift Secure Email Gateway recognizes data classification labels and ensures the correct security treatment is applied, this includes checking the recipients are authorized to receive the data and encrypting it before it sends.

For additional protection from data being harvested and used in phishing attacks, hidden document metadata (author, usernames, server names, etc.), comments and revision history is automatically removed from documents as they are sent and received. To prevent internal actors from exfiltrating data using steganography, images are also sanitized.

More organizations are moving to email providers, such as Microsoft Office 365, for cloud-based email. Cloud-based email allows more file storage, easier file sharing, and the ability to protect files by backing up data. Convenience should not overlook email security, which is why the need for cloud-based email security solutions only increases. These cloud-based email security solutions protect against email threats such as phishing and malware in a flexible environment to give a more comprehensive protection.
