Our customers say

"This sotware is really great. It's a relief. Because my server is constantly under attack. Thanks RdpGuard" - Joaquim De Sousa Marques

"Nice product. I used to implement something similiar in a low-tech and cumbersome manner via a script called TSBlock (not mine). This makes it much easier and is well worth the pricetag for SMB's." - J. Johnson

"Absolutely amazed at your product. We are a church in the North Dallas area, and I discovered this morning multiple failed logon attempts via our Remote Access Server. A friend suggested your product, so I immediately downloaded the trial. It had a list of about five blocked IP addresses in minutes, and that was enough to lead me to push the BUY button. Over the past 10-15 minutes the list is now about thirty with at least a third being international attempts to break into our system. Thanks for a great product. You may have just saved us much grief." - John Hallford

"Love the software. RDP on our Windows servers is just ridiculous. We would block it in the router but we have lots of old-time customers that would have issues." - Scott Hirsch

"Love the software! Makes it easier than tailoring VB Scripts!!" - Nick Brennan

"It's a great product - really stopping those RDP attackers :-)" - Dave, UK

"First of all: Your application is very (!!!) useful and I like it very much securing my 2012 R2 server. RdpGuard is the best solution, I found on the market and after 10 minutes of testing it I ordered the fully-featured version. :-)" - Carsten Baltes
