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 VR Verified Reviewer Assistant Manager - IT Network and Operations Banking Used the software for: 2+ years ### "Nessus - Stay compliant" July 12, 2021 4.0 When it comes to compliance, Nessus really plays major roll. Nessus ensures that your network is accurately assessed. Pros Nessus gives you scan presets that are designed for each compliance body such as PCI, HIPAA, NIST etc. Administrators can easily select the patch level and run the vulnerability assessments. And even you can customize it as per your requirement too. Cons Nessus scanner becomes bit laggy when it comes to scanning of nodes with large data sets and applications. 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 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 Sa facilité d'installation et d'utilisation. Cons Certains paramètres essentiels sont manquants ou mal documentés Review Source VR Verified Reviewer Associate Consultant - Cyber Security Services Information Technology and Services Used the software for: 1-2 years ### "Run and Gun!" June 30, 2019 5.0 Pros 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. Cons 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. 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 .

CISO Banking Used the software for: 1-2 years ### "Nessus - best vulnerability manager" April 2, 2021 5.0 We use Nessus and we are very satistied. Pros The price. Dashboards. Very fast scans and very detailed reports. Cons User group management can be more efficient. Alternatives considered [Invicti Web + API (formerly Acunetix)](https://www.capterra.com/p/171379/Acunetix/) Reason for choosing Nessus The price and the functionalities. 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 IT Lead Aviation & Aerospace Used the software for: I used a free trial ### "Bang for your buck!" November 26, 2019 5.0 Overall, we have been very pleased with the trial. The software has helped us identify and re-mediate vulnerabilities in our environment and fills a gap in our security requirements. Pros We are currently trying out Tenable.io and using the Nessus scanner to run local vulnerability scans and remediation at our company. I like the ease of setup and use of the Nessus scanner and the detailed reporting that is available with Tenable.io (cloud version). Cons The Nessus scanner does utilize a lot of system resources and the scan (less than 50 nodes) can take up to 2 days to complete. It would be nice if the scan was faster. Reason for choosing Nessus We had a conference call with the BreachLock CEO and felt we were brushed to the side due to the size of our company and the timing of our purchase. We went with Nessus instead. 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 [Invicti Web + API (formerly Acunetix)](https://www.capterra.com/p/171379/Acunetix/) Reason for choosing Nessus Very good price. Easy to use. Fast scans. Very good reports.

It also allows analyzing web environments and ensuring that companies know what threats and vulnerabilities are present in their information assets.

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.

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 MW Matthew W. AM Automotive Used the software for: 1-2 years ### "Nessus Review" June 6, 2024 5.0 Pros I like the ability to scan everything on the network and get a report on vulnerabilities. Cons Sometimes the vulnerability scan is a little too picky. Review Source Fábio S. Senior Software Security Analyst Computer Software Used the software for: 6-12 months ### "Good automated tool, but lots of false positives" February 17, 2023 5.0 Pros 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. Cons 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. 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 JV Joevanne V.
