What is a Network Vulnerability Scanner?

The network perimeter of a company is the 'wall' which isolates the internal network from the outside world. However, because the outside world needs to access various resources of the company (ex. the website), the network perimeter exposes some network services (ex. FTP, VPN, DNS, HTTP, and others).
A Network Vulnerability Scanner is designed to map all the services exposed on the network perimeter and detect if they are affected by vulnerabilities.

Details about our scanner

The Light version of our Network Vulnerability Scanner performs a very fast security assessment with minimum interaction with the target system. It starts by first running Nmap to detect the open ports and services. Then, based on the results returned by Nmap, our network scanner interrogates a database with known vulnerabilities to see if the specific versions of the services are affected by any issues.
This detection method, while being very fast, it is prone to returning false positives because it relies only on the version reported by the services (which may be inaccurate).
The Full version of the Network Vulnerability Scanner uses OpenVAS as a scanning engine. OpenVAS is the most advanced open-source vulnerability scanner, which can actively detect thousands of vulnerabilities in network services such as SMTP, DNS, VPN, SSH, RDP, VNC, HTTP, and many more. OpenVAS does vulnerability detection by connecting to each network service and sending crafted packets to make them respond in certain ways. Depending on the response, the scanner reports the service as vulnerable or not.
We have pre-configured and fine-tuned OpenVAS on our servers and have also added a very simple interface on top of its complex functionalities. The engine is running in a distributed environment and it can perform multiple parallel scans.
