Insurance Agency Owner Small-Business (50 or fewer emp.) 6/20/2021 "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?

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?

We will continue our work to always improve SecurityGateway. 5/18/2021 Current UserValidated ReviewerSource: Organic EI Erik I. Small-Business (50 or fewer emp.) 12/21/2020 "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, rasomware 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. Review collected by and hosted on G2.com. Recommendations to others considering Security Gateway: It is an optimal solution with which you can strengthen security and provide confidence to potential customers, especially around anti-spam threats, providing first-level results, thanks to its innovative and adaptable functions. way in which it works, in a fast and easy way, without complexity for all those who want to manage it, allowing scalable learning and development through it, it works in an excellent way in organizations of any nature and size. Review collected by and hosted on G2.com. What problems is Security Gateway solving and how is that benefiting you? The files we handle are now more protected, this includes all those that are attached or stored in the email route that we use most often, implementing Anti-Spam and antivirus filters that serve as a strong to detect all threats, even through a complete encryption that serves as a complement to the security of our system. We can in turn add all those suspicious senders to a black list, so that they cannot send any threat. Review collected by and hosted on G2.com.

CEO Small-Business (50 or fewer emp.) 2/18/2019 "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. Recommendations to others considering Security Gateway: I would recommend it, however make sure that you don't need to integrate another antivirus product into your gateway product or look at forums for ways to get around the 3rd party antivirus integration issues. Review collected by and hosted on G2.com. What problems is Security Gateway solving and how is that benefiting you? We are filtering our Exchange environment with SG for several domains. It works well and the anti-leak features is fantastic for several companies. Review collected by and hosted on G2.com.

SH Shaun H. Small-Business (50 or fewer emp.) 7/8/2020 "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. Recommendations to others considering Security Gateway: Download the 30 day demo and set it up. You have nothing to lose, it’ll take you 30 minutes tops providing you have general knowledge of your environment. Review collected by and hosted on G2.com. What problems is Security Gateway solving and how is that benefiting you? I am using Security Gateway in front of Microsoft Exchange Server to filter email and DDoS attacks at parameter. Security Gateway can also be used for a mail relay to keep the traffic away from your exchange organization if you have lots of SMTP traffic. Review collected by and hosted on G2.com.
