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.

The project was a success. I recommend Nessus.

The soft is very useful to identify and manage vulnerabilities. The implementation was fast. Easy to scan and easy to generate reports. Predefined report for the management. Also you can generate compliance reports.

We did not find problems. Nessus is working very well.

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.

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.

The Console . The Tenable Nessus console has all the modules like M, PC ,Discovery . The Same agent can be used to perform all these tasks and scan for vulnerabilities . Its pretty straightforward and easy.Plus Integration it offers with other tools is awesome to have.

Tenable helps companies discover, design, diagonoze,defend and monitor their business assets and corresponding threats .

Reporting format is a bit shaggy if you would ask me ..But having said that , the addition and deletion of controls also has to be more easily doable.

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.

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.

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.

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

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

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

Simply love using this tool

Perfect tool for consultants as you can load it on a laptop and move from client to client. Without paying for more licenses

Reporting is a little lacking and can do with some rework.

Good canned reports and dashboards, which show where your critical risks are. Ability to export date into CSV or Excel format was welcome and made manipulating data easier.

What I like most about Nessus is that they have many plugins available for the various vulnerabilities that are out there. The ability to scan static and dynamic asset lists is great. The ability to schedule recurring scan jobs is helpful and aids in the scanning of systems. Integration with ticketing systems such as ServiceNow is also great.

It would be nice if their website had the published or revised date of their plugins. Resolving issues related to their Nessus Agents would also be nice. The UI could be improved so that queries didn't take so long. It would be nice if there was an easy way to purge old data associated with particular IPs.

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

That it was really easy to implement and use

The reports are very basic and need to improve.

Nessus is one of the best vulnerability scanning tools in the Cyber Security field. There are no arguments with the functionality of the tool providing itself. As an overall comment, Nessus is very good to manage your infrastructure assets from cyber attacks.

Nessus is very unique and has a user-friendly interface. Also, the deployment is very easy and we can update plugins by using GUI.

As per my 2+ years of experience with the Nessus tool, sometimes it contains false-positive results. Therefore, we need to manually go through all results before submitting them to our customers.

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

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.

I have a very good experience with Nessus . I highly recommend it.

This is a one of best software for the vulnerability assessments. It ha lot of functions and features to do the tasks.

Sometimes it's getting slow to conduct the scans and also I think it need to contain more attractive reporting methods.

Nessus allows you to perform both authenticated and unauthenticated scans for a list of hosts within your network to check for potential vulnerabilities and missing patches, out dated software etc. The post presentation so nicely done and all referrals are there to plan out the remediation process if there are any.

You have to have a powerful rig to get the most out of this software since it's a bit CPU hungry. It'll get days to run a scan for 100 hosts if you have low end system.

This is a really useful scanning software to help us detect any vulnerabilities in our network that need to be patched.

The software can be difficult to use sometimes and it doesn't always scan with the credentials needed to have compliant scans.

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

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

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