"Security Gateway Is a Great Choice for Hosted Email Protection"
5/5
What do you like best about Security Gateway?

First of all, this excellent company offers a very accurate spam filter. Their well-designed security system has a full line of custom settings to make sure even the most aggressive spammers don't put any of their garbage spam in your inbox. Secondly, their spam filter makes sure your valid emails don't end up in the quarantine area. False positives are a weakness of many competitors. Adding in protection for many other forms of email assault, such as phishing and viruses, you now have the best security system for your email. The cost of their Security Gateway is much more competitive than any of the other security vendors. If you are looking for high-quality security protection at a very fair price, you must give these folks a try. Their personalized tech support is also top-shelf and very refreshing. In my opinion, tech support is just as important as the product itself is. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

"Great Solution to SMTP traffic"
4.5/5
What do you like best about Security Gateway?

Security Gateway is a very easy platform to install, very light and with a very friendly administration.

Something positive is that it does not consume many server resources, I have validated it in a physical and virtual environment, its impeccable performance, to have historical logs if it occupies a lot of space.

Very few problems in its administration and operation, the integration with MDaemon Mail Server is great. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

The updates sometimes generate problems and the support is limited in schedule, the forums exist, but the times are very high.

Logs for review and monitoring is not as clear as MDaemon Mail Server. Review collected by and hosted on G2.com.

Response from Emma Washington of Security Gateway

Thank you so much for you positive feedback, as well as your constructive criticism! We will continue our work to always improve SecurityGateway.

"Security Gateway Very reliable to keep the company safe. !!"
4.5/5
What do you like best about Security Gateway?

In our company we can stay more calm because we implement its security measures that are highly reliable and capable of protecting all our emails, blocking threats in a detailed way, managing to eliminate the maximum possible amount, among these are viruses, spam, phishing, ransomware that are the ones that most try to filter in our system. We implement this solution as the main source of threat detection to nourish ourselves with its tools and improve our workflow thanks to its rapid analysis of emails. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

It is an application that in terms of function and efficiency has no problems, however, visually it is not a powerhouse on the market. Certainly this type of software is more sought after due to the powerful of its tools and the quality of results, but there are companies that also want to implement innovative platforms in all aspects, but it is not a feature of great relevance for us, and therefore we can navigate in it in search of its great management results.

"Flexible, Inexpensive and Efficient"
4.5/5
What do you like best about Security Gateway?

I like the fact that you can give domain admins access to their specific domains, global or domain specific functions, and that there are a lot of options for fine tuning. It works well for spam filtering.

--Edit 9-24-2020--

Since I wrote this, MDaemon has updated their product to include high availability and thus I've moved that from the "dislike" to the "like" category. Thanks guys for listening to your feedback and creating features that we are looking for! Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

They need to work with interfacing with 3rd party antiviruses and separate command line functions that can run external scripts against the email before delivery. Lastly, it needs a service/backup/issue monitoring tool that will notify admins if there are problems. When problems do pop up, we have to use a 3rd party tool to recognize them (such as the service dying for no reason) as SG doesn't send us any warnings. Review collected by and hosted on G2.com.

Response from Emma Washington of Security Gateway

Thank you for your feedback David!

-Edit-

And thank you for your update! We try very hard to listen to our users and make changes and updates based on that feedback.

"Mail protection !!"
4/5
What do you like best about Security Gateway?

It is an easy platform to implement, configure and use. It works perfectly as a filter for spam, phishing and virus emails. Once the configuration is completed successfully, no further intervention is required. Its cost is really good, accessible for all the benefits it provides. Notifications are explicit so it is easy to know what the problem is. The support is excellent, the few problems that came our way were fixed in a very short time. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

It is not a problem in itself but we would like them to add an integration with Outlook or Gmail that allows to automatically include emails to a white or black list. Apart from this we do not have any other type of problem with Security Gateway, they have met our expectations. Review collected by and hosted on G2.com.

Response from Emma Washington of Security Gateway

Thank for your feedback Alexandre, we're so glad Security Gateway is helping your team tackle your phishing, spam, and virus problems!

"Light weight super robust product!"
5/5
What do you like best about Security Gateway?

Simple and easy to setup and get working. You can totally have mail flowing through Security Gateway within 10 minutes of install/config. When fine tuning, the options are well defined. The application is light weight and does not require lots of resources. I like the AD integration for authentication sources so that you can have multiple servers for multiple domains. This solution works for hosting and also for individual organizations. I have used Security Gateway for about 5 years and watched the product evolve. MDaemon Technologies definitely stays on top of the email game and totally incorporates the latest features into their product. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

The envelope encryption is being offered through a 3rd part subscription service and there is no option to host yourself. The support is still at an early stage and I hope that hosting the back end yourself will someday be a possibility. Aside from that, the product is very reliable. Review collected by and hosted on G2.com.

Response from Emma Washington of Security Gateway

Thank you for your comments Shaun, as well as your constructive feedback. We will keep your ideas in mind as we continue to improve Security Gateway.

"Security Gateway protects your organization's email from any threat"
4.5/5
What do you like best about Security Gateway?

It is a powerful email protection for the entire organization with which our workflow has been strengthened thanks to the improvement of our security measures. Its tools are capable of protecting all the email platforms we use, to avoid dealing with conflicts caused by viruses, spam, phishing, data leaks, ransomware, and other network threats. By using Security Gateway, the detection of email threats is much more possible, and in turn, we use their policy enforcement tools to maintain a good flow of emails to and from users. It is a platform that can be accessed in the cloud if preferred, which makes it much faster and lighter. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

The appearance of the interface is not the most up-to-date, there are several aspects that can be worked on to make it more attractive, and it can be better viewed by users who are driven by the visual aspect and not by the functions. All the staff is focused on the tools and the quality of results it offers, so we are very satisfied with the use we have given it so far and it has been positive.

"Trustworthy and reliable email server software."
4.5/5
What do you like best about Security Gateway?

My favourite feature of Security Gateway is the system administration tools that is very easy to configure and maintain the system. Setting up accounts, removing inactive accounts, configuring dial-up access to remote SMTP servers, managing mailing lists, and checking for software updates is just completed by a few clicks. I love that remote administration is supported via the web application. It protects our servers against multiple attacks by offering tools that stop theft, abuse, and unauthorized access to servers or accounts. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

I do not have anything I dislike about the software only that it requires someone with IT knowledge to run the system well. Review collected by and hosted on G2.com.

Response from Emma Washington of Security Gateway

Thank you so much for your feedback Manish, I'm so glad Security Gateway has been an easy, effective solution for you!
