“"An Outstanding on-premises Email Security Solution"”

5.0
Jun 1, 2026
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.

    Exceptional Spam Filtering and Proven Stability

    4.0
    Apr 27, 2026
    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.

    A five stars antispam

    5.0
    Apr 15, 2025
    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

Symantec Messaging Gateway (SMG) Likes & Dislikes

Like

Our IT security team benefits from its near-perfect spam and threat detection accuracy paired with rock-solid operational stability, therefore our private emails rarely get trapped in quarantine by mistake. Also, through the absolute standout filtering effectiveness feature, our team easily catches 98% or more inbound spam, phishing and malware right out of the box.

Like

no thing to like it with this brand

Like

The service has provided easy access to configuration parameters due to its ease of deployment and management, as well as its user-friendly interface. Also, with the systems highly configurable policy engine, our workers are able to create custom filtering rules and controls based on our organizational needs.

Dislike

Irrespective of its high capabilities in virtual appliance on major virtualization platforms, the user interface sometimes feels slow when loading and hides critical settings behind a complex web of nested menus that requires more clicks than they would on modern, cloud-native security platforms.

Dislike

support is very bad

Dislike

While I feel secure and confident using the service, Technical support particularly on acquiring post-Broadcom does not feel satisfying.
