Neophytes and Professionals

There is a first time for everything. Your first steps, your first date, your first child, your first vulnerability assessment scan. A first time for everything. The Retina Network Security Scanner Unlimited makes taking the first step incredibly easy and affordable. For security professionals, it is just another step in making sure your assets are properly secured and is as easy as the first time you did it. While some reading this blog may be offended by the simplicity I am trying to convey, the reality of performing an accurate vulnerability assessment can be a daunting task. Consider all the things that you have to do first:

  • Unrestricted access to all targets in the scan for all TCP ports. No firewalls of IDS/IPS solutions should be blocking the scanner.
  • Verifying the targets will allow a scanner to assess for vulnerabilities and will not reject the scan with native OS tools like a firewall, SYN Flood Protection, or from a local EPP solution.
  • Starting key services such as SSH, Windows File and Print Sharing, and the Windows Remote Registry Service in order for a credentialed scan to authenticate and interrogate the system.
  • Credentials. A complete assessment requires remote login credentials to authenticate using the techniques above and to fully inspect the operating system and applications for vulnerabilities.

The reality is these pre-tasks are harder than actually performing a vulnerability assessment with the Retina Network Security Scanner. Just getting credentials to systems in itself may stop many organizations from even considering a credentialed scan and they may opt to only perform a null session scan against services and ports. While this is more akin to crawling than taking a first step, it is still better than nothing but not enough for best practices and regulatory initiatives like PCI.

Therefore, to help users with the assessments, Retina provides free auto discovery to identify all of the assets within your environment. In addition, when credentials fail or asset services are not available for remote authentication, Retina clearly indicates what the fault was and possible resolutions. In fact, we even provide a report that indicates this: The Access Report.



The Retina Network Security Scanner is designed to make vulnerability assessment simple and easy; even when environments are complex. It allows professionals to continuously assess their networks for security risks and provides beginners the tools needed to get started when best practices have never been performed before.
