March 7, 2018 4.0 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. Review Source Mohamed E. IT Retail Used the software for: I used a free trial ### "Scanner vos défauts IT" July 19, 2023 5.0 Pros facile a installer et a utiliser dans un centre SOC Cons parfois il y a des faux positifs qu'il faut les separer manuellement Review Source VR Verified Reviewer Information Security Analyst Management Consulting Used the software for: 6-12 months ### "Scanning for vulnerabilities" January 27, 2019 5.0 Even though it is time consuming when a scan is running, the end result is pretty amazing. It's great using Nessus. Pros 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. Cons It takes a really long time when doing a scan but Review Source MR Manish R. Project Manager Mechanical or Industrial Engineering Used the software for: 2+ years ### "Excllent VA tool" March 7, 2023 5.0 its very nice and scans all vulnerabilities Pros vulnerability scans and classification is nice with poc Cons vulnerability management is not included in nessus pro, only io or sc has it Reason for choosing Nessus ease of use Review Source CE Chris E. Security Engineer Hospital & Health Care Used the software for: 2+ years ### "Nessus, Finding all those vulnerabilities!" September 10, 2019 5.0 Tenable is one of the best scanners out there to me. Easy to use and easy to hire people with experience in it Pros Nessus is great about releasing new plugins for vulns. It's lightweight and has an agent option or a hardware scanner option. The cost is pretty standard. Cons The reports that tenable can generate are lack luster at best. We use the API to pull the info we want, but that takes more work and development time than we like Reason for choosing Nessus The price and scalability were what we liked the most Review Source VR Verified Reviewer Manager, Information Security Hospital & Health Care Used the software for: 2+ years ### "THE vulnerability scanning software to beat" 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. Review Source VR Verified Reviewer Director Of Information Technology Construction Used the software for: 6-12 months ### "It's a vulnerability scanner" December 10, 2020 4.0 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. Pros 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 Cons 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. Review Source Pasan S. Quality Control Manager National Support Team Information Technology and Services Used the software for: 2+ years ### "Essential tool for Vulnerability scanning " October 5, 2018 5.0 Overall it is a great tool for basic vulnerability scanning and because of plug and play ready to use feature of it Security teams use it often. Pros It's Simplicity of use to the user, great tool for vulnerability scanning for any enterprise. the reports are detailed and easy to understand Cons So far there is not much but if it has the function to record the previous records it will be better Review Source TM Thomas M. Responsable sécurité des systèmes d'information Civic & Social Organization Used the software for: 1-2 years ### "Très bon logiciel" December 7, 2022 5.0 Nessus est en globalité un très bon logiciel que nous utilisons afin d'avoir une couverture de notre infrastructure. Pros Sa facilité d'installation et d'utilisation. Cons Certains paramètres essentiels sont manquants ou mal documentés Review Source VR Verified Reviewer Information Security Analyst Management Consulting Used the software for: 2+ years ### "Effectiveness" April 10, 2020 4.0 I have a very good experience with Nessus . I highly recommend it. Pros This is a one of best software for the vulnerability assessments. It ha lot of functions and features to do the tasks. Cons Sometimes it's getting slow to conduct the scans and also I think it need to contain more attractive reporting methods. Review Source DL Derek L. Network Security Engineer Retail Used the software for: 2+ years ### "Its Great!" May 24, 2022 5.0 Pros Easy to use, and seems to find vuln's on more things than other scanners. Also seems to be updated more frequently. Cons I wish there was a way to combine data from multiple scanners into one report or view. Review Source Darshana K. SOC Analyst Computer & Network Security Used the software for: 2+ years ### "Excellent Visibility" August 23, 2019 5.0 Vulnerability assessments in client domains both internal and external have been highly simplified with the usage of Nessus, making security recommendations easier. Pros It is relatively straightforward to scan an entire enterprise network due to the ease-of-use with the policies that are available. Customized creation enhances the overall process. Cons Configuration expertise is required when it comes to specifically tailored assessments in separate domains. This can be slightly tedious with expected results; but once you get it right, the scans are highly effective. Review Source Gianni G. CEO and Principal IT Security Consultant Computer & Network Security Used the software for: 1-2 years ### "Nessus is the best tool for vulnerability assessments" August 20, 2018 5.0 Pros Nessus has the largest database of vulnerabilities and will most likely find any known vulnerability. Cons 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. Review Source TK Thusitha K. Information Security Analyst Computer & Network Security Used the software for: 2+ years ### "Best Vulnerability Scanner" May 15, 2021 4.0 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. Pros Nessus is very unique and has a user-friendly interface. Also, the deployment is very easy and we can update plugins by using GUI. Cons 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. Review Source VR Verified Reviewer Network and System Administrator Education Management Used the software for: Less than 6 months ### "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. Review Source JA Josh A. CEO Retail Used the software for: 1-2 years ### "We use and we like it" May 23, 2019 5.0 We implemented Nessus very easy, with the support from the vendor. Good price and very good solution. Pros We use Nessus because is very good tool to manage you vulnerabilities. Fast scan and easy to make reports and to monitor vulnerabilities. Easy to adjust the profile scan, easy to add scan targets. Good price and a lot of features. Cons We did not find any problems with the Nessus vulnerability management. Alternatives considered [Acunetix](https://www.capterra.com/p/171379/Acunetix/) Reason for choosing Nessus The features. Easy installation. Mature tool. Very good support from the vendor. Review Source Ben S. IT Consultant Information Technology and Services Used the software for: Less than 6 months ### "Amazing Security Tool" September 26, 2018 5.0 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. Pros 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. Cons 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. Review Source DO Darius O. CEO Information Technology and Services Used the software for: 1-2 years ### "Good vulnerability manager" May 20, 2019 5.0 The project was a success. I recommend Nessus. Pros 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. Cons We did not find problems. Nessus is working very well. Alternatives considered [Acunetix](https://www.capterra.com/p/171379/Acunetix/) Reason for choosing Nessus Very good price. Easy to use. Fast scans. Very good reports. Review Source Mairina V. Líder de Proyectos Used the software for: Less than 6 months ### "excellent tool to mitigate security breaches" July 25, 2018 4.0 With this software it is possible to perform network analysis to determine if there are vulnerabilities in the systems, malware, among other types of ramsomware. It also allows analyzing web environments and ensuring that companies know what threats and vulnerabilities are present in their information assets. Pros That I can analyze networks, web applications, elements in the cloud and customize the type of output or analysis that will be executed, either manually or I can program it. Additionally I like the section to make scanners and comply with PCI policies. Cons So far the tool has covered my expectations. So far the tool has covered my expectations. I usually use it to perform advanced scans where I can select which elements I want to enable. Review Source LF Luca F. IT security consultant Computer & Network Security Used the software for: 2+ years ### "Nessus Professional On Premise" October 10, 2018 5.0 I currently use it to perform vulnerability assessments towards the customers' targets. The results are usually accurate but it's always better to evaluate them manually to confirm/deny their existence. The readability of the results is much easier through the Nessus interface than via the exported reports (PDF or HTML). Pros Very frequent vulnerability database updates Easy to use Good pricing Cons Some false positives Some false negatives Running it in a virtual machine in NAT configuration sometimes does not give results as good as in bridge mode The reporting phase could be much better and should be more customizable Review Source VR Verified Reviewer IT Security Auditor Hospital & Health Care Used the software for: Less than 6 months ### "Best tool for vulnerability scanning" November 13, 2018 4.0 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. Review Source HH Houcem H. Information Security Manager Telecommunications Used the software for: 2+ years ### "One of the best vulnerability management solutions" January 21, 2021 5.0 An excellent vulnerability management tool, with reasonable pricing Pros Rich set of plugins and scan templates Frequent updates Ease of use Fair pricing Free version available Cons Not the best tool for scanning web applications Free version is quite limited (e.g. does not allow CIS benshmark scanning) Review Source VR Verified Reviewer QA Engineer Internet Used the software for: 1-2 years ### "Great vulnerability audit tool" 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. Review Source VR Verified Reviewer Senior IT Systems Engineer Computer Software Used the software for: 1-2 years ### "Great scanning tool!" February 12, 2019 4.0 pen testing our network Pros Really comprehensive and tons of scan and reporting options, easy to start a basic scan or get into the weeds with customizing a more complex scan Cons The cost, the more advanced options are harder to set up and not always clear exactly what you are doing Review Source Similar Products Featured ## Related categories [Vulnerability Scanner](https://www.capterra.com/vulnerability-scanner-software/)[Vulnerability Management](https://www.capterra.com/vulnerability-management-software/)[Network Security](https://www.capterra.com/network-security-software/) ## Send me user reviews about this product ### Fill out the form and we'll send a list of the top-rated software based on real user reviews directly to your inbox.
