“Nessus, a great tool for the analysis and remediation of vulnerabilities”

OverallTenable, 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.
ProsNessus 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.
ConsFor 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 for vulnerability scanning”

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

“Easy to Use Vulnerability Scanner”

OverallGood 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.
ProsWhat 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.
ConsIt 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.

“One of the best vulnerability scanners”

OverallNessus 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.
ProsThis 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.
ConsThe 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”

OverallBest money/capabilities balance.
ProsTenable 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.
ConsIt misses some interesting predefined reports and usefull configuration options comparing to Tenable.io.

“Best tool in the market for Vulnerability scanning ”

OverallIt is very much efficient than any other tools offered by the competitors in scanning. Overall Value for money solution for VA scans in enterprise
ProsIt has up to date plugins to scan latest vulnerabilities or malwares are in the market. Plugins are updated every week to cover latest vulnerabilities. It can scan the scope system based on various standards like PCI DSS and HIPAA which other scanners in the market don't have. It performs credentials scans which other scanners like Qualys,Openvas doesn't offer.
ConsNessus doesn't detect any active protection on scope system which can block the credential scan. It cannot scan device if the 2FA is implemented on the scope system.

“Nessus, Finding all those vulnerabilities!”

OverallTenable is one of the best scanners out there to me. Easy to use and easy to hire people with experience in it
ProsNessus 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.
ConsThe 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

“Nessus Vulnerability Scanner”

OverallIts a good tool but in my personal opinion using the free version of software is enough for testing purposes.
Pros- Ease of use for non-authenticated scans - Trusted in case of Network Infrastructure Scanning - Can scan almost everything on a network - Can take a subnet or range for scanning in one go
Cons- Needs improvement in case of web application scan and authenticated scan. - Very difficult to schedule an authenticated scan for a web application - There are some other tools that take login URL and landing URL. Meanwhile prevents the logout URL for session termination itself which increses ease for users

“Vulnerability Management from the Pioneers of VM”

OverallVulnerabilities across the network, devices and the whole environment. Secyrity needs to be based on several systems that can consolidate data about your security posture and with NEssus is a great place to start when you do not have visibility on what is happening further that your PC and internet.
ProsTrust on leader on VM market and movement Plugins updated daily so, threats and breaches can be identified as they are scanned into the environment Using Nessus Manager you can deploy scanners and agents across subnets, you can schedule multiple scans in your environment Best in class configuration audit data base for compliance check Credential and uncredential scans Agents for sensitive devices or services that can be affected by an active scan or are in transit
ConsNessus in the Pro version is limited to one user Not follow up or comparison between latest scan and recent IP address Change on the network or location increase the IP count even when it is the same device reports customizing can be difficult depending on what is expected to have invasive scan. you are not aware that a specific device or service can be sensitive to Nessus untill you finish with the service stopped or the performance of a service gets compromised.

“Great vulnerability assessment tool”

OverallVery good tool to perform vulnerability assessment for home users to business users.
ProsIt 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.
ConsThe 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 An Excellent Tool For The Vulnerability Management Process Of Any Company.”

OverallNessus 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
ProsThat it was really easy to implement and use
ConsThe reports are very basic and need to improve.

“Enterprise-grade vulnerability scanner”

OverallNessus 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.
ProsVery 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.
ConsMost 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).

“Vulnerability Scanner”

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

“Nessus Professional On Premise”

OverallI 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).
ProsVery frequent vulnerability database updates Easy to use Good pricing
ConsSome 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

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

“Run and Gun!”

ProsNessus 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.
ConsYou 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.

“Excellent Visibility”

OverallVulnerability assessments in client domains both internal and external have been highly simplified with the usage of Nessus, making security recommendations easier.
ProsIt 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.
ConsConfiguration 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.

“Vulnerability scanning at its finest”

OverallVery 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.
ProsEase 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.
ConsSometimes 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.

“Nessus is the best tool for vulnerability assessments”

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

“Amazing Security Tool”

OverallOverall 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.
ProsNessus 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.
ConsFor 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.

“Worth it”

OverallA very good vulnerability scanner
ProsI've been using Nessus since it's very beginning. Frankly speaking, I like the older implementations more. But the recent developments are more mainstream and corporate ready It's fast, comprehensive, and up to date vulnerability scanner that save huge deal of manual testing
ConsSome plugins are buggy and can crash the testing system. Also licensing is a bit of a turn off, even though it's really worth it for professionals

“excellent tool to mitigate security breaches”

OverallWith 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.
ProsThat 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.
ConsSo 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.

“Great vulnerability audit tool”

ProsProbably 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.
ConsSome 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.
