Millions of applications are released each year for various operating systems, some of which may have vulnerabilities that could make it easier for hackers to break into the network. This has made network security, especially computer networks in companies and organizations, a major challenge to counter these threats.

Security teams and corporate network administrators need a tool that allows them to quickly and automatically identify and report network vulnerabilities. In this way, the network can be protected against potential threats before threats occur.

Nessus License

Nessus Vulnerability Scanner is a powerful product of the security company Tenable. Every year, various licenses are released for this product to keep this tool completely up to date. Nessus Vulnerability Scanner is one of the most widely used vulnerability scanners in the world. This product currently has two licensed versions which are “Nessus Home” and “Nessus Professional”. The Nessus Home version is for home users and comes with limited features. The commercial version of Nessus, Nessus Professional, however, has all the features and add-ons for enterprise applications.

This software, with its professional search algorithms and high accuracy, provides its performance results to network administrators with the least false positive errors. Nessus software has a modularly design. This architecture consists of servers that perform the process as well as agents who are responsible for reporting and managing. One of the advantages of the Nessus Vulnerability Scanner over other competitors is that it uses its own scripting language called NASL to assess vulnerabilities. Using this unique scripting language, Nessus License is the best way to deal with possible malicious attacks by hackers.

Nessus Professional has no limit on the number of IP scans or diagnostics. One of the advantages of this software is that the prepared license can be easily transferred to another system if needed. It is also very easy to evaluate the results in this software and it is possible to send reports via email.

Why Nessus License?

Organizational Vulnerability Scanning is an organized approach to testing, identifying, analyzing, and reporting network security issues. Many people confuse the term Vulnerability Scanning with Penetration Testing. While the two are different from each other. Vulnerability scanning is a non-destructive test performed by an automated tool with minimal human intervention. Finally, the purpose of this experiment is to identify systems that are exposed to known vulnerabilities. Based on the results of the vulnerability scan, security officials and IT managers in organizations can take immediate action to repair the vulnerabilities. Vulnerability scanning should be done regularly and as part of the application software development cycle to be effective. It is important to know that vulnerability scanning is a requirement of the PCI DSS standard.

In addition to assessing vulnerabilities, the Nessus License also manages them. These tools automatically prioritize identified vulnerabilities. Therefore, it is easy to decide which vulnerabilities have priority in the investigation.

Why should we use the Nessus License?

Licensed Nessus software allows IT managers and security officials in organizations to identify and repair vulnerabilities, bugs, uninstalled security patches, malware, and network configuration issues.

The Nessus Management Dashboard has several templates for pre-built scenarios, allowing network administrators to perform scans faster and more efficiently. The dashboards in this program also allow the user to personalize. With the help of its powerful plugins, this software scans various vulnerabilities and assets in the network.

First in trust

Nessus Security Scanner has been downloaded and used more than two million times worldwide by 30,000 public and private organizations.

First in accuracy

The Nessus Vulnerability Scanner, with an accuracy of 99.99966%, has the lowest number of false positives in the evaluation results of vulnerabilities among other competitors.

First in proper coverage of vulnerabilities

With more than 60,000 CVEs detected, this scanner has the highest detection of network vulnerabilities and software among other similar products. Nessus add-ons will also be available to owners within 24 hours of the release of the vulnerabilities.


Hardware and software requirements for using the Nessus License

The Nessus scanner requires different hardware depending on the number of hosts to scan. For example, for scanning vulnerabilities up to a maximum of 50,000 hosts per scan, Nessus can perform well with processors with a processing power of at least 4.2 GHz and 4 GB of RAM. If the number of hosts is more than 50,000, it is recommended that the system has an 8.2 GHz processor and 8 GB of RAM.

If you intend to use the Nessus License, you should note that the declared value is the minimum resources required to run this software, and if more resources are allocated, the scanning speed will be much higher.

Nessus software can also be installed on a virtual machine such as VMWare. But the manufacturer recommends that the network card be set to Bridge mode for better performance and more accurate software. Nessus Security Scanner can be installed and run on most 32-bit and 64-bit versions of Windows, Linux and Mac.

Nessus License

Nessus was launched in 1998. It was originally developed as a free remote security scanner software, but was later developed by Renaud Deraison, the developer of Nessus and owner of a company called Tenable Network Security. For personal use, the scanner software is free, but for commercial use, you only need to pay $1,200 per year for one scanner. Nessus was originally designed to be able to scan user security. Like Nmap which can do network discovery. Unlike Nmap, this tool is designed to identify vulnerabilities by scanning the network.

In this tool, when checking some vulnerabilities, if Safe Mode is disabled, it may damage the system, so network administrators expose a system to scan before it enters the production cycle.If you are a security activist, you must have heard of Nessus Scanner, software that detects and reports vulnerabilities on various platforms such as network and operating system. Nessus is an open source software that provides security enhancements by identifying vulnerabilities. Nessus has a special language for assessing vulnerabilities called NASL, which stands for Nessus Attack Scripting Language, which security company executives can use NASL to customize scripts and assess security vulnerabilities.

Nessus Scanner History

Interestingly, this popular software has a specialized language for assessing vulnerabilities called NASL, which has designed the acronym Nessus Attack Scripting Language. Contrary to many people’s beliefs, Nessus has a modular architecture consisting of centralized servers that perform the scanning process and remote clients that report and Perform management processes, security managers can use NASL to customize scripts and vulnerabilities, the most important features of Nessus are as follows:

The Nessus 2 software engine and a number of add-ons are still GPLs, leading to Nessus-based forked open source projects such as OpenVAS and Porz-Wahn. Today, this product is available in two types. A free limited edition and a full subscription option Nessus is available for Linux, Windows and Mac OS X.
