### "Nessus Vulnarability Scanning Tool"

June 22, 2021

5.0

Nessus is #1 Vulnerability scanning tool which I ever seen and also Nessus tool has given fullest support to get PCIDSS certificate to our organization. I strongly commanding others to protect there organization with Nessus tool.

Pros

Administrator can simply use predefined policy and easy to apply related product as a template. Also the reporting is 99.99% accuracy and easy to understand and easy to find a solutions.

Cons

When we define a bulk scan, Nessus tool is getting more Computer/Server resources.

Reason for choosing Nessus

While compare with reviews and others recommendations.

### "If you are not already using Nessus as a core product for security scanning, you should start today. "

August 11, 2026

5.0

We have been using Nessus for years, and run full scans on a regular basis. Issues are resolved as soon as possible after detection and ones that cannot be resolved are documented and reported to management.

Pros

Nessus is an excellent vulnerability assessment tool that can be purchased at very low cost and provides tremendous value and protection to an organization. Their support is excellent, licensing is simple, and the product is always up to date with scanning for zero-day issues.

Cons

The only thing I wish Nessus would improve upon would be the ability to add devices into a custom group, and then be able to select that group for different scans and reports.

### "Decent product with awful price tag"

May 8, 2025

3.0

Solid product, minus reporting. But massively overpriced and undermaintained.

Pros

good for discovery, fingerprinting, and finding CVEs for systems/software

Cons

performance is pretty poor, licensing experience is poor, does not normalize scope data, does not always show its work in scan output, lots of typos in finding text, filtering does not work as well as one would hope

### "A Must have for MSSP"

4.0

Pros

A Professional tool that gives stellar results

Cons

Price can be a bit steep for small businesses

Alternatives considered

[Nexpose](https://www.capterra.com/p/238841/Nexpose/)

As an MSSP, we need to give results to the customer and keep them safe from all vulnerabilities. We cannot choose an inferior product and negotiate with results.

### "Nessus: Vulnerability Scanner with Appealing Reporting Capabilities"

July 29, 2023

4.0

Nessus is a must for network security testing and vulnerability analysis. Together with Nmap, Nessus gives a much better penetration testing and vulnerability analysis of networks and virtualized cloud infrastructures.

Pros

I used Nessus with nmap for testing the vulnerability of virtualized networks in controlled environments. The main motivation behind the selection of Nessus is to have a user-friendly vulnerability report with categorized network exploits and OS weaknesses. Nessus provides accurate results (though some false positives are noticed in hardened Linux environments). The advanced reporting capabilities in Nessus makes the vulnerability results easily exported and documented to relational databases. Moreover, the various Nessus reports can be compared after hardening the OS with different security configurations.

Cons

Nessus is very accurate but sometimes, especially with latest versions of Ubuntu, many false positives are noticed. Still Nessus results are considered highly informative and the false positives can be autonomously filtered to provide more accurate vulnerability analysis and reporting.

### "Nessus Professional Gets The Job Done"

August 25, 2020

5.0

This product does a great job of informing your IT and security groups on what may be vulnerable in your environment. Especially if your organization is looking to begin a program, start small and use this service to build up your processes and program before sinking large amounts of money into other services or products.

Pros

Nessus is still the industry leader in this arena, and the ability for the product to identify vulnerabilities accurately is still the high water mark to beat. You can be up and running in just a few minutes, and the ability to have recurring scans is a great way for this product to help you with your security program. The "Plugin Output" fields help greatly when trying to determine if tests are a false positive, and lends additional credence to your system administrators when you can show them exactly \*why\* something has been detected as a vulnerability.

Cons

There are no ways to track vulnerabilities or your efforts to monitor them over time; this truly is just a point-in-time view of your environment unless you upgrade to a much more expensive product.

Alternatives considered

[InsightVM](https://www.capterra.com/p/169723/InsightVM/)

Reason for choosing Nessus

The cost was a no-brainer; by paying one low fee instead of a per-IP address model we can ensure that there are no hidden surprises and that we have enough money to address other security projects at our organization.

### "Nessus for vulnerability scanning"

July 17, 2019

5.0

After our first major client security audit, we implemented Nessus to run weekly internal and external vulnerability scans. Not only does this help satisfy our client demands, but it helps us find vulnerabilities in our systems and helps us find patches and solutions to the vulnerabilities.

Pros

Easy to set up, use and report on. We started using this application after our first major client security audit a few years ago. It's a been great tool.

Cons

Not much to dislike with Nessus. Maybe some better reports, and the cost could always be better, although it's not bad.

### "Tenable Nessus: Excellent tool for security testing"

February 3, 2025

5.0

This is one of the best tool I've used, very competent and shows great results. Accuracy of scans are good and detects most vulnerabilities like SQL injection, XSS, and other misconfigurations. Automated scans are very friendly to setup and compares scope to OWASP top 10 vulnerabilities. Overall performance is good and also doesn't overload website. We even have multiple tenable products and it's integration with tenable.io ecosystem is great.

Pros

API support for automation and integration into CI/CD pipelines. Great scanning capabilities with form based and token based authentication. Reporting of results with CVSS scoring are accurate and remediation fixes are provided by this tool itself

Cons

Handling of dynamic applications with complex authentication needs improvement. Scan timings takes more than ETA

### "Great Software to Detect Vulnerabilities"

December 12, 2024

5.0

Nessus has been a great tool for the company I work at. Deploying it is just a matter of installing it, and putting in the right information in the installation, which can be automated. Once it's installed, it just works. It detects every known vulnerability there is.

Pros

Vulnerability scanning in Nessus is very accurate, it rarely gets anything wrong. It is also easy to deploy.

Cons

The only downsides of Nessus that I have experienced are that sometimes it gets false positives, but not very often, and that the UI of the website can be finicky sometimes.

### "Nessus for buisness "

January 12, 2023

5.0

The vulnerability assessment and the scanning helps our buisness to grow much faster than the manual approch which also has the chances of human errors

Pros

The way thet the nessus scanner scans the web applications and the range of networks effectively and provides the analysis of the vulnerability present with the CVE codes and the ways to mitigate the vulnerability with the proper documentation report for the same which builds the trust on the nessus software and this capabilities are the main reason we recommend nessus scanner to each and every security teams

Cons

The nessus comes with the best available functionality and it is preferable over other tools but it also comes with the huge cost that is very high compared to other scanners

### "One of the best vulnerability scanners"

January 8, 2019

5.0

Nessus has allowed us in the company to develop a timely remediation system, since with the results of the scanners our clients can manage the remediation in a more timely manner without needing to apply more invasive policies on the client. Additionally it has helped us that the scans can be done in a short period of time in comparison to others in the market and in this way improve our service.

Pros

This product is one of the best network scanners on the market. After properly installing the server with the scanner in the network and placing the credentials of the administrator, the system works perfectly. Vulnerability scanning and compliance scanning are executed properly, all the standards included in Nessus are very useful.

Cons

The vulnerability scanner is not totally accurate in some situations and some results must be checked to verify the vulnerability. Therefore, it is possible that there are false positives. Many times the supplements are not updated in a timely manner and this hurts even more with the false positives generated.

### "Most comprehensive tool for security and compliance assesments"

March 21, 2019

5.0

Best money/capabilities balance.

Pros

Tenable products dictates market standard for securty assesment. Nessus Profesional is part of that family. It has simillar capabilities like Tenable.io but can be run inside your datacenter as a stand alone solution. It's easy to configure, reliable and what's most importand it will give you a hint how to solve every voulnerability detected inside your infrastructure.

Cons

It misses some interesting predefined reports and usefull configuration options comparing to Tenable.io.

### "Nessus An Excellent Tool For The Vulnerability Management Process Of Any Company."

January 14, 2019

5.0

Nessus it’s an excellent tool for the vulnerability management process of any company. Its super easy to use and implement on any network, and the tenable university and the community it’s a plus that make it even easier. There are many way how to export the result of any scan, but the best are in HTML and PDF, because are easy to understand and explain to any person. I really like it and going to continue using it

Pros

That it was really easy to implement and use

Cons

The reports are very basic and need to improve.

Pros

It did what it was advertised to do and did it well. The updates to the plugins were done regularly and it found everything out there that was a vulnerability

Cons

Lacked reporting module that helped show more of the picture for non technical people and pretty graphs. To get those you needed to move to Tenable.io or SecurityCenter.

April 5, 2019

5.0

Pros

Nessus is the gold standard of vulnerability scanning. A robust solution, highly customizable for every organization with cloud, on prem and client install options.

Cons

Without the local client or group policy that shuts off wifi when your on wired you may get hit with 2 licenses per device because it sees both the wireless and wired instance. Something to know going into it if you are buying.

### "Vulnerability scanning at its finest"

July 23, 2019

5.0

Very happy we purchased and implemented this software. It allows you to be proactive in locating vulnerabilities on the network and patching them before something bad happens. Well worth the cost.

Pros

Ease of use and simplicity. Rarely have had to reference online documentation. They make it very easy to figure out and use right away. For more specific sets of scans or devices, the documentation is helpful. There is also a very active community on their forums. Reporting is very informative, and scheduling makes it so you don't have to interact much after everything is all set.

Cons

Sometimes there are some false positives that take time to realize. Also seems to think many of the things they mark as medium risk are low risk. This depends on your situation and network, but for me most of the medium risks can be disregarded.

Pros

It is easy to use very intuitive, completely modular, mature and highly scalable from small networks to operational networks critical for security

Overall very helpful to understand your network security posture. Value for money at enterprise level.

Pros

Very handy, powerful and easy to use software for vulnerability scanning. This can be also utilize for web application scanning and system configuration review. One can schedule the scanning and get the report. It gives standard and custom reports which are helpful for presentation purpose. Nessus scanning reports suggest the required patch for their respective vulnerabilities. To get the best possible result plugins should be up to date with latest release.

Cons

Report doesn't show in graphical format. It doesn't scan system with 2FA enabled.

September 22, 2018

4.0

Pros

Probably the best vulnerability scanner out there. There are plugins for every vulnerability, and it can scan either credentialed or uncredentialed. It is very easy to use, and generates really good reports and provides good feedback.

Cons

Some things on the website are rather slow, and there could be better flexibility to manage older data, like from hosts that are no longer in service.

March 3, 2021

4.0

Nessus is my first local and network scanner. So far it's doing a pretty decent job!

Pros

For threats that are generally manageable and can easily be detected, Nessus is the to go-to scanner of choice

Cons

For novice administrator, more especially for those with less computer savviness, the configuration of this is very challenging
