Symantec Messaging Gateway (SMG)

Symantec Messaging Gateway being an outstanding on-premises email security solution, we use the Data Loss Prevention (DLP) feature in our organisation to monitor outbound emails and prevent accidental or suspicious leakages of sensitive or confidential data, which has helped us to achieve a 98%+ spam catch rate with remarkably low false-positive counts.

As a regular user of Symantec Messaging Gateway, I have benefited from its ability to protect email systems by filtering spam, malware, phishing and targeted attacks by providing data loss prevention and content control. With this experience, I have felt secure and confident in the Service.

Overall, I like Symantec Messaging Gateway since you can access any configuration parameters with a web interface. It's a powerful tool that allows you to integrate with other software for security checks.

It is one of the top and well-known on-premise gateway solutions. Truly exceptional in spam filtering - I think that no other solution can compare in this matter. SMG functions as a highly reliable sentry for corporate email.

SMG is a vm machine that comes with a simple interface (you manage it via https) . It is a really good antispam, we usually configure it to scan emails to on premise exchange server. there are several tabs with many functions: you can have look at quarantine, release mails, add good senders and new spam criteria. Of course you can search for messages and have look at logs. The mail domain addresses receive quarantine notification that inform they hold mails in spam. The main dashboard displays a summary with release version, license expiry, statistics. Updates are easy to do, sometimes they take 10-20 minutes, so plan them not in work hours. And take a snapshot before proceeding. on internet you can find a lot of information and support about SMG. Remember to add your SSL certificate and keep your product updated, I suggest to create a snapshot before update it (update may take a lot of time). You can create a "list" of good and bad senders and create your own policies (e.g. emails containing certain word must be quarantined). The interface looks a bit old (i mean spartan) but personally i prefer this way
