Stop ransomware and other threats

Forcepoint Email Security uses the Advanced Classification Engine (ACE) to identify threats ranging from annoying spam to advanced malware, phishing, and Business Email Compromise (BEC) attacks.

Block data theft with content-aware DLP

Advanced capabilities detect data theft concealed in images or custom-encrypted files, even when gradually transmitted in small amounts to evade detection.

Identify high-risk user behavior

The rich data collection capability can quickly generate a report on Indicators of Compromise to identify infected systems and suspicious user behavior.



Email security describes various techniques for keeping sensitive information in email communication and accounts secure against unauthorized access, loss, or compromise. Email is a popular medium for the spread of malware, spam, and phishing attacks, using deceptive messages to entice recipients to divulge sensitive information, open attachments or click on hyperlinks that install malware on the victim’s device. Email is also a common entry vector for attackers looking to gain a foothold in an enterprise network and breach valuable company data.

Email security is necessary for both individual and business email accounts, and there are multiple measures organizations should take to enhance email security.

How Secure Is Email?

Email was designed to be as open and accessible as possible. It allows people in organizations to communicate with each other and with people in other organizations. The problem is that email is not secure. This allows attackers to use email as a way to cause problems in attempt to profit. Whether through spam campaigns, malware and phishing attacks, sophisticated targeted attacks, or business email compromise (BEC), attackers try to take advantage of the lack of security of email to carry out their actions. Since most organizations rely on email to do business, attackers exploit email in an attempt to steal sensitive information.


Because email is an open format, it can be viewed by anyone who can intercept it. This became an issue as organizations began sending confidential or sensitive information through email. An attacker could easily read the contents of an email by intercepting it. Over the years, organizations have been increasing email security measures to make it harder for attackers to get their hands on sensitive or confidential information.

Email Security Best Practices

One of the first best practices that organizations should put into effect is implementing a secure email gateway. An email gateway scans and processes all incoming and outgoing email and makes sure that threats are not allowed in. Because attacks are increasingly sophisticated, standard security measures, such as blocking known bad file attachments, are no longer effective. A better solution is to deploy a secure email gateway that uses a multi-layered approach.

It’s also important to deploy an automated email encryption solution as a best practice. This solution should be able to analyze all outbound email traffic to determine whether the material is sensitive. If the content is sensitive, it needs to be encrypted before it is emailed to the intended recipient. This will prevent attackers from viewing emails, even if they were to intercept them.


Training employees on appropriate email usage and knowing what is a good and bad email is also an important best practice. Users may receive a malicious email that slips through the secure email gateway, so it’s critical that they understand what to look for. Most often they are exposed to phishing attacks, which have telltale signs. Training helps employees spot and report on these types of emails.
