FTP Brute-Force Protection for Windows - Block Repeated Login Attacks

Brute-Force Protection for Your FTP Server

If you are running FTP on your Windows Server, you may observe thousands of failed login attempts in your FTP logs.

Repeated failures across many usernames can be a sign of brute-force attacks on your FTP server. Attackers use automated tools and password dictionaries to try hundreds or thousands of combinations.

Selected IIS FTP log fields showing repeated failed logins (530).

Someday they may succeed and your server might be compromised! Even with a strong password, brute-force attacks consume your server resources: CPU, RAM, bandwidth and disk space.

RdpGuard allows you to protect your FTP server from brute-force attacks.

It reads supported FTP server logs, including FTPS login attempts, or monitors unencrypted FTP traffic on standard or custom ports.

If the number of failed login attempts from a single IP address reaches a set limit (three by default), the attacker's IP address will be blocked.

For 64-bit Windows and Windows Server. Supported Windows versions.

"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
