Spam firewall recommendations

Spam Firewall
Looking for a spam firewall. We previously used SonicWall but looking at other options. Can anyone recommend alternatives? I'm looking for something hardware based for around 200 employees but scalable. Looking to spend under $4k.

I absolutely love our Barracuda Spam Firewall 300. It is way under 4 grand even with 2 years of support and updates.

You can find out specific information about it and even request an evaluation unit by going to Barracuda Networks.

It does spam and virus catching via hourly updates and a bayesian database/filter. You train it and it works.


I’ve worked with the Barracuda solution and it works great. Models from 300 and above in addition to the spam and virus features provides you the capability to reduce directory harvesting attacks (random e-mail address generation) against your internal Email server. One feature of this product is that there is no “per user” license. You just buy the box for your environment dependin gon how many e-mails you expect per day (example) and that’s it. Most other products charge you per user which brings the price way up there. There are Outlook plug-ins so you users can send “spam” e-mails that bypassed the barracuda and it will send a copy to Barracuda’s SPAM Central for analysis so other companies are protected as well.

I would highly recommend you go this way!


We are currently using McAfee’s email gateway. We purchased it when it was called IronMail and was owned by Secure Computing. McAfee just recently acquired Secure Computing. The unit works great and blocks a lot of email spam from getting in.

I am also testing out a product called Untangle. They have a free product that includes:

* Web Filter
* Virus Blocker
* Spam Blocker
* Attack Blocker
* Phish Blocker
* Spyware Blocker
* Protocol Control
* Routing & QoS
* Firewall
* Intrusion Prevention
* OpenVPN
* Reports

and then you can add on purchased items such as:

* Live Support
* eSoft Web Filter
* Kaspersky Virus Blocker
* Commtouch Spam Booster
* WAN Balancer
* WAN Failover
* Policy Manager
* AD Connector
* Remote Access Portal
* PC Remote
* Branding Manager

it is a great product. check it out.

See this previous question for other hosted alternatives – why pay for bandwidth at your network’s edge when you can have this done “in the cloud”?

    We use a spam filter provided by MX logic, and it is the best filter that I have seen in the last 6 years. We had tried several over the past 6 years only to be dissapointed. We finally found MX Logic and Spam is no longer an issue, it is pricey but in my opinion worth every penny. We have used it for the last 2 years with no issues whatsoever . The way it works is all mail goes through their filters first prior to being delivered to our exchange server. If it finds any Spam it quarantines it and then sends an email with a link to the quarantine so you can decide wether or not to release it or not.
