Tenable, in its variety of versions has a large section to train its customers, it is not a surprise that escalate positions with the passage of time and with every improvement that creates true expectations. Within the company we have deployed Nesss and it really has been helpful to fin every vulnerability that the scans throw at us, the information is very complete from the discovery stages, we feel very satisfied, that the tool has been implemented in other infrastructure and the results are very heplful.

Nessus and its graphical interface is attractive, I would say that minimalist but punctual and charming, it is very clean, it should be applauded that in each version they improve it and include some types of scans that can bring you more complete results when you carry out an analysis. It is very remarkable that the plugins in your database are up to date and that your community generates an adequate response on time.

For now all the experience I have with Nessus has been nice, with the constancy that you have in your team working every day to improve it I know it will be a good tool for vulnerability detection.

Nessus has done a spectacular job in vulnerability assessment in our company which has helped us to maintain secure environments in the cloud and on premise. Configuring nessus was a straightforward forward task and it carries out in depth scans within a short time. Nessus comes with build in vulnerabilities which you scan against your systems to find out if there are vulnerabilities present.

I like how you get an alert promptly when nessus detects an attack on any of your systems. I also like the wide variety of plug ins made available by nessus for specific vulnerabilities. I'm also impressed with how nessus allows you to create your own tests related to you company. I like how it is always releasing updates on new vulnerabilities which you can check in your systems. Nessus provides suggestions for alleviating detected vulnerabilities in your systems.

Nessus still has the issue of false positives which is common in most vulnerability scanners whereby nessus detects vulnerabilities that are not present. It is not user friendly in terms of costs since it is expensive if you want to access more features through the paid versions. Aside from that, I am certain that we have been able to get the best from this tool.

The client side agent is lightweight and easy to deploy once you get it successfully installed and reporting in. The adminstrative console is somewhat confusing, but provides very detailed reports that you can customize to your liking.

Does what it is supposed to. Provides a good overview of vulnerabilities across systems for internal security assessments and audits. Easy to deploy MSI package

Support is something to be desired. During initial setup in our environment, there were several complications when attempting to connect machines to the tenable.io cloud and provide the client machines with updates. The support group couldn't provide necessary assistance and we ultimately left to troubleshoot on our own.

Nessus is easy to use and easy to deploy vulnerability assessment solution available. One of the best features is nessus can be easily deployed to air gapped environments without much changes to the environment.

Nessus has limited reporting and vulnerability management features as compared to other tools.

Great tool for vulnerability scanning, easy to use, full of very useful features.

Nessus allows you to run vulnerability scans to multiple networks simultaneously. It has various features that can be used for specific scans (web, PCI DSS, etc), as well as generic scans. Very easy to use. The reporting feature is also great, as it is very well formatted and it's possible to export the results into various formats.

Everything is great as is in Nessus, especially if compared to other competitors. Nothing negative to say about it.

Among the strong points of Nessus we can certainly mention its user-friendliness, the easy deployment, and the very accurate reporting.

The only flaw of Nessus is that if you don't purchase the "Tenable Web App Scanning" subscription, doing authenticated scans on web apps (especially if they implement authentication mechanisms such as SSO) presents problems, since even specifying credentials (or cookies) it can happen that Nessus fails to authenticate.

Very good tool to perform vulnerability assessment for home users to business users.

It supports from simple host discovery scans to detailed vulnerability scans like malware scan, credential path audit. This tool can also perform scan to test the latest vulnerabilities like Meltdown and Spectre and WannaCry ransomware etc. This vulnerability scanner has almost up-to-date plugins. The plugins are updated almost daily to weekly to scan the latest vulnerabilities in the market. Nessus scanner can perform the vulnerability scan for various operating systems like: Windows, Amazon linux, CentOS, FreeBSD, MacOS, Redhat, Debian etc It also supports vulnerability scan for various compliance standards like PCI DSS. This scanner can also perform credential based scan on the target machine. The major advantage is, this scanner gives the most accurate vulnerability details about the machine with very few false positives which other scanners in the market fails to do.

The professional version of this tool is very costly. It yet doesn’t support credential based scan for machines which have 2 factor authentication implemented on it.

Nessus provides me with an in-depth overview of the vulnerabilities of every asset in the organization. The vulnerability management system integrated with it makes prioritization very easy, so you can quick work progressively towards a secure environment.

Very easy to use. Very easy to configure a scan. Very easy to export a report and data about a scan. Very easy to customize scan templates. You can also create your own audit templates, so you can customize this tool for the specific policies of the organization. If you get to know the ins and outs of the scanner, you can get the most value from it.

Most of the time the documentation is incomplete if you get picky with the use cases. Support via Tenable Support Portal has been very slow lately, it seems like if they had a single person to handle all the support cases they have everyday. It used to be slow, but that's been improved a lot in the latest version I've used (7.0.2).

Ease of use and variety of dashboards we can make.

UI can be improved a bit features like customizing themes, colors/tool bars can be added more frequently.

I use Nessus for external vulnerabilities. It is reliable and easy to implement.

I don't think there is anything I don't like so far.

We use Nessus and we are very satistied.

The price. Dashboards. Very fast scans and very detailed reports.

User group management can be more efficient.

After comparing it with other tools, in relation to quality / price it is a great tool beating its competitors in price

A very low false positive rate and a very intuitive interface

It would be desirable to make comparisons possible between different audits over time

It is very useful for sever scanning for protecting user information. In addition, Nessus will give clear devices scanning for data base scanning and firewall scanning. This is very ideal for security auditors and cyber security analysts. Nessus tool gives recommendation for fixe the bug.

Nessus is a vulnerability Scanning tool helps to identify Known Vulnerabilities, Malware, Patches and etc. There is a free trial version every use can use. Nessus can work under any OS version. It is very helpful to protect our PC and Servers from any fraud or threat. Simply it’s very effective and compliance with user preference.

In the paid version includes more features than trial one but license cost is higher. It takes too much time to scan security devices.

Even though it is time consuming when a scan is running, the end result is pretty amazing. It's great using Nessus.

I use this scanner often to scan web application and also to run other scans. It provides the best results and it is really helpful as this also saves some time. There's are variety of scanning types available in this scanner and after scanning it gives a full report including the url when scanning a web application.

It takes a really long time when doing a scan but

Nessus proved to be an effective solution for identifying potential security weaknesses and ensuring compliance across our infrastructure. With advanced detection techniques and detailed reporting capabilities, Nessus facilitated streamlined remediation of identified issues.

For a small organization, the cost of the product can be too high to bear. At times the most recent CIS benchmarks may not be available to conduct compliance scans.

An excellent vulnerability management tool, with reasonable pricing

Rich set of plugins and scan templates Frequent updates Ease of use Fair pricing Free version available

Not the best tool for scanning web applications Free version is quite limited (e.g. does not allow CIS benshmark scanning)

We have an amazing scanning functionality with NESSUS and it's scheduled so all I have to do is look at the report then can use that to report to the committees

It can be troublesome to setup the very first time but when it is set up it is a breeze to use

Tenable offers great vulnerability management products and Security Center is very easy to use. Great reporting capabilities and an overall great product.

Ease of use Reporting

Lacking in application security

Nessus has the largest database of vulnerabilities and will most likely find any known vulnerability.

In some cases, Nessus assumes that a service is vulnerable to a vulnerability just because it is listening for incoming connections, so you always have to go through the results and carefully double check each finding.

Overall Nessus is incredibly powerful, it seems better setup for corporate environments and I think in that environment you could not ask for a better software.

Nessus is very easy to use and it houses a lot of known vulnerabilities. Reporting from a scan couldn't be easier. Timely updates are also necessary for any vulnerability scanner worth its salt, and Nessus updates regularly to cover any emerging threats in a timely manner.

For the paid version its pricey but you can't put a price tag on keeping things secure. My experience lies in the free version that is available for home use. It requires you to request a key, which is fine but it took close to 3 days for the email to be sent with the key. I'm hoping this was a fluke but it was unfortunate. Occasional bugs have also occurred, but what software doesn't have the occasional bug.

This is one of the best value for money network scanner out there.

Installation and Implementation is really easy Number of Plugins available to scan different environments The UI is very user friendly

Scan time can be improved. Progress of scans is can be improved and list can be broke to IP's finished vs IP's still being scanned

Nessus is an industry-standard tool for doing security evaluations. It is well known and does an admirable job and finding vulnerabilities. It provides clear and concise reports.

It does take some familiarization to new admins to create new scans. This process could be more intuitive.

its very nice and scans all vulnerabilities

vulnerability scans and classification is nice with poc

vulnerability management is not included in nessus pro, only io or sc has it

Nessus is the state of the art on automating vulnerability scans for networks and infrastructure. It has lots of customization options and can be deployed locally to make an active scan on the internal infra. or through the cloud.

It can be expensive to keep it running for smaller business. Also, many false positives can be encountered and then depends on the analyst to interpret and classify each vulnerability along with a more appropriate severity.

It was a quick process to get an overview of the systems on my LAN and turn that data into actionable insights.

Took some tuning to get reporting correct.
