Strong and deep scanning, against all types of threats that may affect the vulnerability of any of the services we are running, this security system, has an advanced detection of hacker attacks of all kinds, the updates are constant and automatic, plus if you wish it can be updated manually, in case of finding any vulnerability that the tool has not detected due to any lack of update, it is an exception, but the possibility of doing so exists, something I like very much are the notifications, that really they have importance, since they warn of some type of vulnerability that may exist in the network, and this system warns you before it can touch you, to update the databases, and have a protection against these attacks, which are just emerging.

The creation of reports from the analysis performed, lacks necessary data, to perform a deeper analysis of how to detect and prevent some incidents of this type, would like to obtain much more detailed reports, where each vulnerability is detailed, with statistical data, possible origin of the vulnerability, and recommendations, of blockages for this type of vulnerability.

**Reviewed by:** Lidia  M. | Marketing analyst, Mid-Market (51-1000 emp.)

**Reviewed Date:** February 19, 2019

**What do you like best about Tenable Nessus?**

Nessus offers enormous flexibility in how it tracks vulnerabilities across the network. The scan is multiplatform, it can be executed in local, network objectives or as an agent. You can launch the scan from outside the firewall, which offers the real visibility of the company. The implementation and configuration of Nessus is very simple, we like to use the agents to create groups of scans and in this way automate the process. Everything works very well and the creation of reports is perfect to keep track of remediations. I like that we can do the compliance analyzes.


**What do you dislike about Tenable Nessus?**

We had a problem with a client where the requirements to deploy Nessus could not be applied, the Tenable team has not yet been able to give us a strong response to resolve the situation. The information provided to perform the remediation is not the best possible, I would like to improve on new updates a better tool for this. The automatic updates of the supplements should be more consecutive.

**Recommendations to others considering Tenable Nessus:**

I recommend Nessus and Tenable because with them we have been able to establish an important service within our company. It is an excellent tool to scan objectives and present reports.

**What problems is Tenable Nessus solving and how is that benefiting you?**

With Nessus we carry out the vulnerability and compliance scan, to then carry out the remediation cycles in our clients' networks. With Tenable's enormous base of knowledge and threats, we make sure to attend to every detail that could be a cause of attack on the network. Thanks to the agents we can also evaluate the host in particular to have a more granular scheme..

**Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.)

  ### 24. Good overall product with room for improvement

**Rating:** 3.5/5.0 stars

**Reviewed by:** Jon K. | Mid-Market (51-1000 emp.)

**Reviewed Date:** December 12, 2018

**What do you like best about Tenable Nessus?**

Nessus includes some good functionality to enable integration with a larger suite of vulnerability management systems and help facilitate some light automation. The performance is generally consistent and the interface is intuitive and easy to use. 

**What do you dislike about Tenable Nessus?**

The plugins are not always updated in a timely fashion, which results in unnecessary false positives and time spent researching and documenting. The API functionality is tied to a Tenable.io subscription, limiting automation and integration to the more expensive subscription model, and the accompanying analytics are superficial and don't tie to good key risk indicators. 

**What problems is Tenable Nessus solving and how is that benefiting you?**

As a consultant, I'm helping my clients assess where they may have shortfalls in their vulnerability management, patch management, and system hardening programs. The overall ease of use and ability to deploy remote virtual systems allows us to work with clients without being on site the entire time, improving our efficiency and controlling costs.

**What do you like best about Tenable Nessus?**

Cost is the biggest factor, the functionality is on par with other commercial solutions but at a reasonable price point and licensing model.  The solution is also extremely stable.  The information presented in reports is easy to understand and can be put infront of a non-technical audience, a junior admin, network engineer or audit team.  

**What do you dislike about Tenable Nessus?**

Nessus professional lacks robust data management and compression, scan history can grow rapidly out of control.  We have been forced to implement so scripting outside of the tool to perform housekeeping activities that would be better served natively.   

**Recommendations to others considering Tenable Nessus:**

Evaluate what you plan to do with the information you receive from the tool, prioritize information that is highest risk and be sure to get support from you business to move toward integrating Nessus into your risk programs life cycle

**What problems is Tenable Nessus solving and how is that benefiting you?**

Nessus is our primary risk analysis tool and is the foundation of how we demonstrate risk mitigation to our Clients.  We can rapidly get Client security buy in to go live once we present the Nessus compliance and vulnerability reports.  By reducing the time to get Client sign off we are able to realize revenue sooner.

  ### 36. De Facto Standard in Vulnerbility Scanners - Best Vulnerbility Scanner for the price.

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Government Administration | Mid-Market (51-1000 emp.)

**Reviewed Date:** December 12, 2018

**What do you like best about Tenable Nessus?**

Nessus Professional  is an Intelligent and highly customizable security product. Our team gets very accurate scan results. The security plugins are always current. The compliance templates provided can be customized to reflect the our regulatory and security needs.   

**What do you dislike about Tenable Nessus?**

Improve the Web GUI:
The Nessus Web GUI does take some getting used to. Additionally, advanced configuration settings could be better organized and contextual help should be added / improved when navigating the web GUI. More report customization would aid in providing better management reporting.  Disk space utilization and system health should be added to the web GUI as this would help to alert administrators and users if and when system logs require pruning or to proactively clean old scan jobs that are consuming disk space. 

Security Compliance:
The security compliance templates are very useful but the compliance templates could be expanded to cover more vendor products and the compliance templates should be maintained at current levels to reflect changing compliance standards. 

Mobile App: 
There are times when I am away from my desk and we would like to have a mobile version that would run on a portable platform such as a Android phone or tablet.

**Recommendations to others considering Tenable Nessus:**

Must be comfortable with customizations. Should have a strong understanding of networking technologies.

**What problems is Tenable Nessus solving and how is that benefiting you?**

With respect to patch management, we use Nessus to validate new server and network appliance builds. As a government organization, we are required to adhere to security policies pertaining to security compliance and cyber security. To us, Nessus definitely fills are security compliance needs. 

  ### 37. Great tool for self-assessments and scanning new deployments

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.)

**Reviewed Date:** December 12, 2018

**What do you like best about Tenable Nessus?**

Great interface, portable (I run it on a laptop), and the reporting format has been great for developing a methodology with which I can track my organization's security posture over time.

**What do you dislike about Tenable Nessus?**

Very little to dislike here.  I think the only thing I'd like to see is a summary interface that does some of my reporting work for me, instead of me having to review the reports and create totals for each vulnerability category (critical, high, etc.).

**Recommendations to others considering Tenable Nessus:**

You should consider this a must-have in your security toolbox.  You can use it to self-assess as well as a check against third party assessments.

**What problems is Tenable Nessus solving and how is that benefiting you?**

I can scan new systems before they go into production, I can monitor our security posture over time as new threats emerge and we deal with existing ones, and I have used the data from the reports to track our security for over four years running now.

  ### 38. Nessus Professional

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Printing | Mid-Market (51-1000 emp.)

**Reviewed Date:** December 06, 2018

**What do you like best about Tenable Nessus?**

The best thing about Nessus is how indepth the scans can be. Not only are they indepth, there are multiple different scans preset for convenience. Not only that there are a ton of customization options for reports, scheduling, notifications, the type of scan and even the plugins.

**What do you dislike about Tenable Nessus?**

Migrating Nessus to a new machine isn't the easiest thing to do as there are some restrictions but after doing them a couple of times, I've gotten used to it. Depending on how many scans you have on your original build, migration can take a long time to complete. If something goes wrong, all of that time would have been wasted.

**Recommendations to others considering Tenable Nessus:**

If you are in need of a vulnerability scanner, Nessus is definitely the way to go. The ease of customization and the level of support you get from Nessus makes this the best option. 

**What problems is Tenable Nessus solving and how is that benefiting you?**

A big benefit with Nessus is that we are able to pinpoint security risks within our own sites and servers on a monthly basis and escalate to the proper teams within our organization. The scans can be setup to send emails of the pdf file of the scan report to individuals. This allows the proper people are receiving the results as soon as the scans are complete.

  ### 39. Best Security Scanner.

**Reviewed by:** Verified User in Computer & Network Security | Mid-Market (51-1000 emp.)

**Reviewed Date:** June 22, 2019

**What do you like best about Tenable Nessus?**

Nesus professional is all in one tool it's having multiple options for scanning the security stuff like servers, firewall, network, web applications and hardware devices. It's provide accurate results of the scanning. and screenshot we will not provide its against company policy.

**What do you dislike about Tenable Nessus?**

It's take more time to update. Compare to other scanning tools.

**Recommendations to others considering Tenable Nessus:**

Work on updates.

**What problems is Tenable Nessus solving and how is that benefiting you?**

We can scan multiple system during same tims. So it's very useful for us and it provide the good results with any format of report.

  ### 40. Powerful Vulnerability assessmnent tool at a more than reasonable cost

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Government Administration | Enterprise (> 1000 emp.)

**Reviewed Date:** December 20, 2018

**What do you like best about Tenable Nessus?**

Speed! I can get accurate results from a Nessus scan much faster than I get from other products costing 1000% more. The interface is extremely intuitive and I can configure a scan quickly compared to my other tools. It is my 'Go To' system when a client requests a scan to validate patches of config changes.

**What do you dislike about Tenable Nessus?**

What I dislike has nothing to do with the tool itself. I dislike that my manager feels the cost of the tool is indicative of its overall worth and reputation.

**What problems is Tenable Nessus solving and how is that benefiting you?**

I use Nessus Pro to complement our vulnerability assessment program and to validate detections in order to determine false positives. I consider this tool as an invaluable asset in hardening our PCI and DMZ environments.

  ### 41. Nessus is a top tier scanner that is easy to use and effective at finding vulnerabilities.

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.)

**Reviewed Date:** December 20, 2018

**What do you like best about Tenable Nessus?**

Ease of use.  The application is easy to setup and use with canned templates that get you scanning for what you need to find.  The scan results are among the most accurate I have seen which is welcome in this day and age.

**What do you dislike about Tenable Nessus?**

The scan results could be easier to read.  Sometimes I find the scan results to be a bit difficult to read with the current setup.  However after you play around with the settings a little and get used to the format it is not an issue.

**What problems is Tenable Nessus solving and how is that benefiting you?**

For me vulnerability threat management and tracking installed patches is the primary use of Nessus.    The benefits of using Nessus is getting a well priced top tier application for a fair price.  

  ### 42. Good vulnerability assessment tool

  ### 43. Great Product

**Rating:** 4.5/5.0 stars

**Reviewed by:** Clark M. | Systems Administrator, Information Technology and Services, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 12, 2018

**What do you like best about Tenable Nessus?**

I like the user friendliness of the interface

**What do you dislike about Tenable Nessus?**

I'm not sure I like the new vulnerability grouping that shows for each host (purple color)

**What problems is Tenable Nessus solving and how is that benefiting you?**

We mostly use Nessus to see what known security patches have not been applied yet.  This allows us to enforce patching of all systems (Windows and Linux).  This has allowed us to have a monthly dashboard highlighting vulnerable systems and has enabled us to ensure that all systems have all known security patches within a 60 day window.

  ### 44. Nessus is the gold standard for vulnerability scanning.

**Rating:** 4.0/5.0 stars

**Reviewed by:** Christopher K. | Senior DevOps / Windows Engineer, Internet, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 12, 2018

**What do you like best about Tenable Nessus?**

Nessus offers great support for the platform and the documentation is thorough for an easy implementation and configuration.

**What do you dislike about Tenable Nessus?**

The pricing model has changed and some features now require a larger financial commitment or maintaining older versions, which is obviously not desirable for a security and compliance tool.

**Recommendations to others considering Tenable Nessus:**

Definitely read the documentation before you get started, it will save a lot of time and make sure everything is configured correctly.

**What problems is Tenable Nessus solving and how is that benefiting you?**

Nessus allows us to set and forget the majority of our vulnerability scans and provides all the details we need to ensure our environments are not opening drastic new security holes. This allows us to focus on more critical security issues, while also maintaining our compliance information without user interaction.

  ### 45. Best CPE integrated Vulnerability assessment tools

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Computer Software | Enterprise (> 1000 emp.)

**Reviewed Date:** June 23, 2019

**What do you like best about Tenable Nessus?**

Great tool used for getting vulnerabilities in server router switches.  One of the best tool recently added CPE Vulnerability assessment

**What do you dislike about Tenable Nessus?**

There is an integration of CPE it creats some proxy issue please make the issue resolve as soon as possible

**Recommendations to others considering Tenable Nessus:**

Keep going . There is no other tool in market which can compete nessue

**What problems is Tenable Nessus solving and how is that benefiting you?**

Best vulnerability comes after the results 

  ### 46. Great for Compliance

**Rating:** 2.5/5.0 stars

**Reviewed by:** Verified User in Computer & Network Security | Enterprise (> 1000 emp.)

**Reviewed Date:** December 18, 2018

**What do you like best about Tenable Nessus?**

I like that you can set the scans up manual and have them scheduled.  I love the customer support. 

**What do you dislike about Tenable Nessus?**

I do not like that you cannot scan applications or webservers. 

**Recommendations to others considering Tenable Nessus:**

I WOULD try to figure out how to have Nessus run vulnerability scans on software, if that is possible. If I could improve Nessus I would find a way to make it take up less band with when doing network scans, find a way to get it to scan different types of software and also, get it to scan webservers.  Nessus for me needs to keep staying in compliance with the IRS publication 1075 and NIST 800-53 series.  If Nessus can do that then it will continue to hold its excessive valuableness. Federal guidelines are the way that I would go if I were a Nessus developer/tester. 

**What problems is Tenable Nessus solving and how is that benefiting you?**

scanning applications and webservers.  I like the reporting tools and compliance validity of the compliance control sets via the same set the IRS uses.  That makes it definitely more valuable than using any other vulnerability tool.  This tool tells you what controls are missing as well as what controls need to have improvement and if you use the same files as the IRS uses you are sure to pass any safeguard review/audit.  I have my security administrator use it just because of that reason.  I wish Nessus could run scans on different types of software but I'm not sure how that is even possible.  If there were any improvements to be made it would be on webservers and applications.   However, if your just checking your audits against safeguard reviews, this will get you passed. 

  ### 47. Nessus Vulnerability scanner

**Rating:** 3.0/5.0 stars

**Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.)

**Reviewed Date:** December 20, 2018

**What do you like best about Tenable Nessus?**

Nessus allows scan for different kinds of vulnerabilities as denials of service, default passwords, misconfigurations. It is supported on a lot of operating systems and platforms.It also has an evaluation trial that helps you to decide if it is good for you or not. I think is great for big companies. 

**What do you dislike about Tenable Nessus?**

It cant manage all scans from one location. So doesn't have centralized management.  It doesn't provide roles based access. It doesn’t seem to offer long term solutions and the support it is no so fats.

**Recommendations to others considering Tenable Nessus:**

Compare with others products and check the requirements you need so you are sure Nessus apply to your environment

**What problems is Tenable Nessus solving and how is that benefiting you?**

Vulnerabilities scanner. Protection. Security 

  ### 48. Tenable Nessus Professional Review

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Utilities | Mid-Market (51-1000 emp.)

**Reviewed Date:** December 06, 2018

**What do you like best about Tenable Nessus?**

Nessus Professional has many wonderful features.  Some these features include the ability to view vulnerability information related to system that reside on your network.  It gives you information about how to remediate these reviews.  We use Nessus in an active and passive manner.  We do have ICS based systems that do no work well with active scans.  In these instances we can set up a passive Nessus scanner and collect the information that we need.  It is also helps to in providing a secondary means to identify and verify the patching of our systems.

**What do you dislike about Tenable Nessus?**

We use Nessus Professional as a part of our Tenable SC CV suite.  This can be a little difficult to get up and running the first time it is set up.  There are multiple virtual appliances that have to bet set up and synced together and if there is ever a problem, sometimes this it can take some time to track down which particular component is the issue.  If Nessus Professional is used as standalone product, this isn't an issue.

**Recommendations to others considering Tenable Nessus:**

Be prepared to spend some time on the front end designing and setting this up properly to avoid headaches down the road.

**What problems is Tenable Nessus solving and how is that benefiting you?**

It has helped in reducing cost associated with working individually on each device we have.  We trust Nessus to perform automated tasks that would normally take hours on end to perform this type of audits by hand.  So with that, we have seen a reduction in labor costs and time.

  ### 49. Excellent for Vulnerability Scanning. 

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Computer & Network Security | Enterprise (> 1000 emp.)

**Reviewed Date:** June 22, 2019

**What do you like best about Tenable Nessus?**

Best for Vulnerability Scanning on any server and have best support from tenable.
It's updated with most recent attacks Vulnerability plugins. 

**What do you dislike about Tenable Nessus?**

There is nothing to be a disadvantage, but can be more better in future.

**What problems is Tenable Nessus solving and how is that benefiting you?**

  ### 50. Great tool...simple, intuitive, and complete

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Oil & Energy | Mid-Market (51-1000 emp.)

**Reviewed Date:** December 06, 2018

**What do you like best about Tenable Nessus?**

Nessus is my go-to scanner.  It's simple to use...has a well laid out user interface...and results are easy to digest.  The references withing the vulnerability findings are immensely helpful to support staff in helping them to understand the findings and their path to remediation.

**What do you dislike about Tenable Nessus?**

Not really much to dislike here.  Price is right.   Ease of use is great.  Only thing I'd recommend is for Tenable to step up their game with Support.   Their support process is one of the least engage-able of all the tools I use.  Much more feels like consumer level support rather than enterprise.

**Recommendations to others considering Tenable Nessus:**

none at this time

**What problems is Tenable Nessus solving and how is that benefiting you?**

Verifying patch management process is the primary solution we are solving.  Is also great at asset discovery.  We also find the scanner very useful when a new high priority vulnerability comes out that the business wants us to quickly verify our exposure to.
