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. -

Most spam filters work like this: receive e-mail, queue, filter, deliver or send a non-delivery reply. The problem with this model is that mail is delayed and senders/recipients may never realize that wanted messages were blocked. PerfectMail works in real-time meaning that it filters messages as they are received - without queuing. This means that PerfectMail tells the sender if their message is being blocked. - PerfectMail's antispam engine is programmed C - the fastest programming language in the world.Starting Price: $499 one-time payment -

Warmup Inbox
Warmup Inbox
Warmup Inbox automatically raises your email sending reputation through our network of inboxes that talk to each other. The process of preparing an email address for general use or email outreach is commonly referred to as “Warming Up” an inbox, where you take a number of steps to ensure that an email address does not become deactivated, blacklisted, or automatically marked as spam when it begins to send outgoing messages to other recipients. This process is typically done with newly created email addresses but also benefits older email addresses who have been having issues with email deliverability, in that a noticeable portion of their outgoing mail is either landing in a spam folder or blocked entirely by an email server due to either being blacklisted or associated with a domain that has a poor reputation. Warming Up an email inbox essentially is recreating the way a typical person will use an email address.Starting Price: $19 per inbox per month -
