Calibre One Intelligence Cloud Protection


RDPGuard is a host-based intrusion prevention system (HIPS) that protects your Windows Server from brute-force attacks on various protocols and services (RDP, FTP, IMAP, POP3, SMTP, MySQL, MS-SQL, IIS Web Login, ASP.NET Web Forms, MS Exchange, RD Web Access, VoIP/SIP, etc). It monitors the logs on your server and detects failed logon attempts. If the number of failed logon attempts from a single IP address reaches a set limit, the attacker’s IP address will be blocked for a specified period of time. This is important in protecting your servers against brute force password-guessing attempts, which are a method of gaining access to your secure servers. Most servers are constantly under attack, and RDPGuard is one option in protecting your servers from this specific type of attack. RDPGuard is a very good reactive way of protecting your servers, if you’d like a solution that is both proactive and reactive, C1 Guard may be right for you.

C1 Guard

Calibre One has found that the implementation of a commercial product such as RDP Guard was not enough for our customers. This application was able to reactively block external attacks after a number of attempts. However, that put a lot of load on the server if the external intruder was using any sort of botnet. Remember that a botnet is a network of computers which are used to target a specific network device. For that reason, Calibre One designed, coded and implemented C1 Guard, the first fully Cloud Intelligence Solution. C1 Guard is a cloud based solution which uses the data collected from RDP Guard, and  clever analytics is able to block up to 80% of the external intruders reducing the load on the servers dramatically. C1 Guard is like a standard antivirus, the agent connects to Calibre One cloud intelligent solution using a secure link to retrieve a list of bad actors and with that information, update the server where the agent is deployed. This update happens automatically every 15 minutes. That means, that if a new bad actor is detected in Customer A, the customer B will be protected 30 minutes after RDP Guard + C1 Guard are synchronized. Calibre One Cloud Intelligence Solution has already collected more than 300,000 records in the cloud. That amount of data is periodically analysed in Microsoft Azure and reduced to a manageable size for the C1 Guard agent. Do you have a Windows Server which is exposed to the world and offering services for your business? Then you may need to discuss this with our Sales team which will be more than happy to understand and design a solution for your need.


The cost of C1 Guard is $8.50 per server, and includes reporting and maintenance for C1 Guard/Server. It also includes monthly reporting and updates on the installed server.
