"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. :-)"
