OpenVAS and Nessus by Tenable are two of the leaders in the vulnerability scanning market. See below to learn all about how OpenVAS and Nessus compare against each other in the vulnerability scanning category:

When it comes to choosing an open-source vulnerability scanner, there are a lot of options. The two most popular are OpenVAS and Nessus, but they have very different approaches.

OpenVAS is an open-source vulnerability scanner with a wide range of features. The tool was developed by the Open Vulnerability Assessment System (OpenVAS) project, which started at the end of 2002. The main goal of OpenVAS is to provide a framework for managing vulnerabilities and publishing them in an easy-to-use format.

OpenVAS is an automated tool that scans for vulnerabilities in your system and plugins. It’s designed to be used by security professionals who want to keep their systems up-to-date without manually running a slew of different scanners one after another.

Nessus is another open-source tool created in 1998 by Tenable Network Security. It allows users to scan systems for vulnerabilities and perform other security tests, including port scanning and network mapping. It also offers a paid version that enables users to manage their vulnerability database — the vulnerability management platform (VMSP) — and monitor its performance using the Nessus Management Console (NMC).

Nessus is also an automated scanner that can scan for vulnerabilities in your system and plugins, but its focus is more on finding known vulnerabilities than detecting new ones. It’s also easier for non-security professionals to use than OpenVAS because it doesn’t require any configuration before running a scan; users can simply download the program and start scanning.

OpenVAS vs. Nessus: Partners

The OpenVAS Security Scanner is the core of the OpenVAS platform and provides an interface to manage their scan tasks and receive feedback on the results. The OpenVAS Manager is a web-based management console for the OpenVAS Scanner and can be installed on any machine in your network or cloud infrastructure. OpenVAS Manager provides a simple and intuitive interface for managing scans and events in one place.

OpenVAS has a wide range of partners who support the project with different services, including commercial support, development, and consulting, or by providing hosting for our software repositories or bug-tracking systems.

Nessus is committed to helping our customers get the most out of their vulnerability management solutions. That’s why it has partnered with McAfee, AWS, Siemens energy, Splunk, and Cyberark, which brings new insights into the latest vulnerabilities and provides customers with a wider variety of coverage options.

OpenVAS vs. Nessus: Use cases

OpenVAS utilizes a community-driven development process, which means anyone who wants to contribute can submit patches and fixes for bugs or new features. Anyone can download and run OpenVAS on their computer, but users must register with the project before they can contribute code changes back into the core product.

OpenVAS was created by a community of security professionals who wanted to ensure anyone could access the product without paying for it. This means there are no licensing fees or other costs associated with using OpenVAS — all users need is an internet connection.

Nessus is designed specifically for organizations with large networks, so they can identify vulnerabilities across multiple systems at once. The biggest drawback of using Nessus is that it requires a license fee in order for it to work properly.

Nessus offers more than just vulnerability scanning; it also has other security tools like intrusion detection and intrusion prevention systems (IDS/IPS) alerts, and firewall rule sets. The price of these additional features varies depending on what type of subscription plan you choose when purchasing an annual license agreement from Tenable.

OpenVAS vs. Nessus: Pricing

OpenVAS is free for anyone who wants to use it and can be downloaded from the OpenVAS website. It’s also open-source, meaning you can modify it if you want to. This makes it easy for people to start using the software without having to pay any money upfront.

Comparatively, Nessus isn’t free; it costs about $2,790 per year for each user. Put it another way: With Nessus, you have to pay for every person using the software. If your company has 100 employees, you must pay $100 per person per year plus maintenance fees.

OpenVAS vs. Nessus: Overall

Both OpenVAS and Nessus are excellent vulnerability scanners, but they’re also very different in many ways. It’s important to remember that both of these tools have strengths and weaknesses and that it’s up to you to decide which one best suits your needs.

For example, if you’re looking for a complete vulnerability management solution that includes vulnerability assessment, patch management, and compliance monitoring capabilities, then OpenVAS may be right for you. On the other hand, if you’re looking for a tool that finds vulnerabilities in particular software types, like Windows servers, then Nessus may be better suited for your needs.

Knowing these two great options can help you decide which tool is right for you.
