Ciphermail Appliance
in-put
Email encryption with CipherMail Most emails are sent in plain text. This means that anyone who has access to the data stream can read the content of the emails. This is unacceptable for most companies, institutions and organizations and may also violate applicable law. E-mail encryption ensures security and trust in communication. CipherMail is a central mail transfer agent (MTA) that works on the “store and forward” principle. Incoming e-mails, regardless of whether they are from internal or external sources, are only saved until they have been encrypted / decrypted and can be forwarded to the recipient. This happens without changing the email client and is possible in combination with any SMTP server! E-mail encryption can be done using S / MIME, PGP or in a PDF file - in principle or triggered by a trigger in the subject line. CipherMail also includes a Data Leak Prevention (DLP) module.Starting Price: $670 one-time payment -

ScanMail
Trend Micro
More than 90 percent of targeted attacks begin with a spear phishing email, which means your mail server security is more important than ever. Unfortunately, most mail server security solutions, including the limited set of built-in protections in Microsoft® Exchange™ 2013 and 2016, rely on pattern file updates, which only detect traditional malware. They don’t include specific protections to detect malicious URLs or document exploits commonly used in targeted attacks or advanced persistent threats (APTs). ScanMail™ Suite for Microsoft® Exchange™ stops highly targeted email attacks and spear phishing by using document exploit detection, enhanced web reputation, and sandboxing as part of a custom APT defense, protection you don’t get with other solutions. In addition, only ScanMail blocks traditional malware with email, file, and web reputation technology and correlated global threat intelligence from Trend Micro™ Smart Protection Network™ cloud-based security. -
