Brute-force protection for Remote Desktop Web Access
Remote Desktop Web Access (RD Web Access), formerly Terminal Services Web Access (TS Web Access),
enables users to access RemoteApp and Desktop Connection through the Start menu on a computer
that is running Windows 7 or through a Web browser.
If you have RD Web Access enabled on your server, you may notice a lot of brute-force attempts
that look like below in your Security Event Log:

"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. :-)"
