"Great security product!"

5/5

What do you like best about Security Gateway?

Security Gateway is very easy to use. There is a lot of functionality that can be adjusted by the admin. Settings can be adjusted for exactly what your company needs. Excellent product - gives you a secure feeling concerning email. Our company was bought out recently and switched us to Office 365, which is terrible. I miss my Security Gateway!

What do you dislike about Security Gateway?

Can't think of any "cons" to the product. Review collected by and hosted on G2.com.

"Excellent edge spam/virus filter for the price."

5/5

What do you like best about Security Gateway?

Ease of installation, direct integration with mdaemon mail server. Simple and straight forward for end users to check and release any false positives. Ability to modify how often users receive notification of messages that were quarantined or otherwise not delivered. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

Yearly licensing can be costly especially when a large number is required. Some of the initial setup can be confusing if you are also using built in SPAM protection on an existing mdaemon mail server installation. Review collected by and hosted on G2.com.

Recommendations to others considering Security Gateway:

MDaemon has options to demo the product, it's definitely worth taking a look at. Quick to setup and easy to use. Review collected by and hosted on G2.com.

What problems is Security Gateway solving and how is that benefiting you?

Spam and virus detection and prevention. We've seen a substantial reduction in the amount of malicious/junk email, in the neighborhood of 90%. Review collected by and hosted on G2.com.

"SEcurity Gateway keeps me sane."

5/5

What do you like best about Security Gateway?

I get an enormous amount of junk mail. Security Gateway filters those out so I don't have to deal with them. They also spot the emails with viruses and weed those out. It will also track my company's email and stop any spam from being sent from one of my employees' email. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

There's not much I dislike about Security Gateway. I'm certain there are more tools and things happening behind the scenes that I don't know about. If anyone were to show me, I would probably get tired head and not fully understand the behind the scenes stuff. It would be exhausting for me to try to learn all it can do. Review collected by and hosted on G2.com.

Recommendations to others considering Security Gateway:

I would recommend Security Gateway to anyone with email. Review collected by and hosted on G2.com.

What problems is Security Gateway solving and how is that benefiting you?

With Security Gateway I don't have to weed through all those emails myself and have more time to do real work. I also don't have the downtime due to a virus. Review collected by and hosted on G2.com.

5/5

What do you like best about Security Gateway?

Unfortunately, every company has different requirements, Security Gateway makes an extremely flexible package. That is easy to use and set up. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

Not much to dislike. Software works great at what it does. Review collected by and hosted on G2.com.

"Great email filtering product, support staff are knowledgeable"

4/5

What do you like best about Security Gateway?

The flexibility of the filtering rules using the well understood SIEVE language. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

There are some weird quirks with advanced configurations that aren’t immediately obvious. Sometimes I end up rewriting built-in features in SIEVE to add more control. Review collected by and hosted on G2.com.

Recommendations to others considering Security Gateway:

Start simple, mirror your current configuration and be sure that if your existing mail server has any filtering (in particular SPF, EHLO, IP, etc) you bypass this filtering for mail coming from SecurityGateway. Review collected by and hosted on G2.com.

What problems is Security Gateway solving and how is that benefiting you?

Email filtering (spam filtering, virus scanning). Review collected by and hosted on G2.com.

"Don't worry"

4/5

What do you like best about Security Gateway?

We don't receive unwanted mails anymore, not mails from registered spam addresses, no outbreak mails - and only very few spam mails you have to treat manually. Review collected by and hosted on G2.com.

What do you dislike about Security Gateway?

When we receive mails from e.g. our payroll company, they are by default rated as spam, because the attachment (pdf) is password protected. Whitelist is ignored. Review collected by and hosted on G2.com.
