Internet Message Access Protocol (IMAP) is one of the most popular protocols for email retrieval nowadays.
Almost every mail server supports IMAP.
Anyone is able to download ready-to-go tools and start abusing your server's resources.
Being so popular, it's no surprise that this protocol becomes the target for brute-force attacks very often
- the Internet is full of tools for IMAP brute-forcing. Anyone is able to download ready-to-go tools
and start abusing your server's resources.
If you are running IMAP on your server, you may notice thousands of repeating entries in your logs like the one below:
Those repeating failed login attempts are actually brute-force attacks on your IMAP service. These attacks consume your server's resources
such as bandwidth, RAM, CPU, and free disk space.
If some of your IMAP users have weak passwords, attackers may succeed in brute-forcing their way into the user's
mailbox and gain unauthorized access to their emails and other personal information.
RdpGuard
provides effective protection for your IMAP server against brute-force attacks by detecting invalid login
attempts and automatically blocking the attacker's IP address.
RdpGuard is compatible with all IMAP server software,
making it a versatile solution for protecting your email service.
RdpGuard monitors the IMAP port(s) or logs on your server and detects failed login attempts.
When the number of failed login attempts from a single IP address reaches a pre-set limit (by default, three),
RdpGuard automatically blocks the attacker's IP address.
For Windows Vista/7/8/8.1/10/11 and Windows Server 2008/2012/2016/2019/2022
"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
