Sys Defender Test Appliance


Identify and Remove Your Vulnerabilities
If your organization depends on the Internet and Modern Technologies to conduct business, you have to stay one step ahead of emerging hackers, viruses and threats. If you do not, your business will be disrupted and that could be very costly. It makes good business sense to periodically test your Internet, I/T Technologies and Communications services for vulnerabilities and risks.

Use the proven, Test - Patch and Repeat - security strategy for identifying system, network and software  Vulnerabilities. Thousands of tests (Nessus licensed) are performed with expert remediation advice provided.


This portable appliance reduces your cost of security testing. Reports are based on proven methods and reveal “Risk Levels”. Executive Summary and Detailed (HTML) Reports are delivered with CISSP consulting included. 

Some businesses need regular testing and/ or a Vulnerability Management system to help them better manage their security environment.  Having a SysDefender on your network, full time, helps xDefenders deliver its Monthly or Quarterly Subscription Service, for regular and adhoc vulnerability testing. 

Types of Vulnerability Assessments:

  1. External Vulnerability Assessment simulates a hacker trying to penetrate your firewall.
  2. Internal Vulnerability Assessment simulates a disgruntled employee, malicious contractor, competitor and attempts to exploit vulnerabilities inside your firewall and on your LAN.
  3. Host Benchmark Report Review to compare with best industry practices.
  4. Social Engineering attempts to gain access and vital knowledge by communicating with employees and business partners.
  5. Wireless Vulnerability Assessment uses drive-by and walk-by attempts to gain access to private wireless networks and assets, using modern technology.
  6. Database and Web Application Assessment to determine security protections at these levels of the business.
Nessus Test Appliance
For External and Internal Vulnerability Assessments, xDefenders offers our SysDefender, a hardened Linux based server with powerful open-source scanning software. The appliance is updated periodically to stay current with known vulnerabilities and vendor patches. Thousands of built-in tests automatically interrogate IP based network devices and servers. A database of findings is created with severity levels assigned to help network and system administrators quickly identify and remedy vulnerable ports, operating systems and applications. An Executive Summary and Technical Report are created and findings are reviewed with the client.

  • Plug-in architecture - Each security test is written as an external plug-in. This way, you can easily add your own tests without having to read the code of the testing engine.
  • ASL - The Security Scanner includes an Attack Scripting Language, designed to write security tests easily and quickly. Security checks can also be written in C.
  • Up-to-date security vulnerability database - We mainly focus on the development of security checks for recent security holes. Our security checks database is updated on a daily basis, and all the newest security checks are available, including FTP servers and mirrors.
  • Client-server architecture - The Security Scanner is made up of two parts : a server, which performs the attacks, and a client which is the front end. You can run the server and the client on different systems. That is, you can audit your whole network from your personal computer, whereas the server performs its attacks from the SysDefender, which is in the data center.
  • Concurrent Testing - Tests multiple hosts at the same time.
  • Smart service recognition - . SysDefender does not believe that the target hosts will respect the IANA assigned port numbers. This means that it will recognize a FTP server running on a non-standard port (31337 say), or a web server running on port 8080
  • Multiples services - Imagine that you run two web servers (or more) on your host, one on port 80 and another on port 8080. When it comes to testing their security, SysDefender will test both of them
  • Tests cooperation - The security tests performed by SysDefender coordinate with your configuration so that useless tests are not performed. If your FTP server does not offer anonymous logins, then anonymous-related security checks will not be performed.
  • Complete reports - : SysDefender will not only tell you what's wrong on your network, but will, most of the time, tell you how to prevent crackers from exploiting the security holes found and will give you the risk level of each problem found (from Low to Very High)
  • Exportable reports - : The Unix client exports SysDefender reports as an easy-to-parse file format.
  • Full SSL support - : SysDefender has the ability to test SSL services such as HTTP, smtps, imaps, and more. You can even supply SysDefender with a certificate so that it can integrates into a PKI-field environment
  • Smart plug-ins - (optional): SysDefender will determine which plug ins should or should not be launched against the remote host (for instance, this prevents the testing of Sendmail vulnerabilities against Postfix or "optimizations")
  • Non-destructive - (optional): To minimize the risk to bring down services on your network, xDefenders enables the "safe checks" option of SysDefender, which will make SysDefender rely on banners rather than exploiting real flaws to determine if a vulnerability is present
  • Independent developers - The SysDefender developers are independent. We will not suppress a vulnerability because we have a relationship with the authors.
