Network scanning refers to the use of a computer network to gather information regarding computing systems. Network scanning is mainly used for security assessment, system maintenance, and also for performing attacks by hackers.
Network scanning is an important part of network security that any system administrator must be comfortable with. Network scanning usually consists of a port scanner and vulnerability scanner.
Here we are listing the top 4 Network Vulnerability Scanners:
Netsparker finds and reports web application vulnerabilities such as SQL Injection and Cross-site Scripting (XSS) on all types of web applications, regardless of the platform and technology they are built with. Netsparker’s unique and dead accurate Proof-Based Scanning Technology does not just report vulnerabilities, it also produces a Proof of Concept(POC) to confirm they are not false positives.
Basically there are two version of Netsparker tool are available –

Nessus is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network.
Nessus is a proprietary vulnerability scanner developed by Tenable Network Security. It is free of charge for personal use in a non-enterprise environment.
According to surveys done in 2009 by sectools.org, Nessus is the world’s most popular vulnerability scanner, taking first place in the 2000, 2003, and 2006 security tools survey. Tenable Network Security estimated in 2005 that it was used by over 75,000 organizations worldwide.
Nessus allows scans for the following types of vulnerabilities:
- Vulnerabilities that allow a remote hacker to control or access sensitive data on a system.
- Misconfiguration (e.g. open mail relay, missing patches, etc.).
- Default passwords, a few common passwords, and blank/absent passwords on some system accounts. Nessus can also call Hydra (an external tool) to launch a dictionary attack.
- Denials of service against the TCP/IP stack by using malformed packets
- Preparation for PCI DSS audits
