For over 6 years now MIMEsweeper for SMTP has been securing our business from email based threats, without so much as a hiccup! This product and the company behind it do a wonderful job of adapting the program to the latest threats out there!

Years ago I implemented MIMEsweeper at a previous company and I was pleased with the capabilities. With G&T Conveyor Company MIMEsweeper has been working great for us since 2003 and as we've learned more about it we've taken advantage of more of it's capabilities. SPAM and e-mail viruses continue to multiply and yet MIMEsweeper is keeping up with the increase and helping us continue to protect and defend our end-users.

10! Clearswift is a good company! We run Websense product for web filtering and 2 times I told them that their tech support sucked compared to you guys. When I call I want to talk to a technician NOW. So never stop putting money in that area. You guys are doing an amazing job!

For over 2 years our MSW Appliance has done a fantastic job of preventing masive amounts of SPAM from reaching user mailboxes, and has required very little admin intervention. Great product and worth every dollar.

We have been using MimeSweeper for SMTP for many years and I would happily recommend it. MimeSweeper offers me the flexability I need to keep our mail traffic moving, or not depending on the content at the same time as protecting our internal mail servers from attack.

Wayne Siegler
Systems Administrator, Pensacola Christian College
Because of its scenario-based architecture, MIMEsweeper for SMTP has given us the most control in managing our complex e-mail filtering policies. Although we've had some installation and upgrade hiccups over the years, MIMEsweeper's technical support has been very helpful in solving issues that arose. MIMEsweeper for SMTP's performance has been good overall. MIMEsweeper was also a significant savings over the competition making it an easy choice.

We've been Clearswft customers for some time, but we really like the latest version ( easy to find what you need - much more user friendly). The Edge solution is doing a great job at stopping spam and the amount of time we need to spend managing & tuning email has dropped considerably.

I worked previously as an IT consultant and had always recommended Clearswift's MIMEsweeper for SMTP software because I considered it to be head and shoulders above the competition. So when I came to Towergate I immediately rolled out the software across the organisation.
