A vulnerability assessment tool with patch management capabilities that offers ease of deployment
Pros and Cons
  • "The initial setup of Tenable Nessus is very easy."
  • "The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."

What is our primary use case?

I use Tenable Nessus for vulnerability assessment so that you can scan for CVEs and existing CVEs. Tenable Nessus will show you the latest update on those vulnerabilities and where it needs patches, so it goes hand in hand with patch management. As soon as you scan, you can see whether it needs patching, and if needed, you can go ahead and deploy patch management to address the current issue.

What is most valuable?

The most valuable features of the solution are the policy and the active scan. The features are different for Tenable Security Center since it is more on an on-premises model. The solution also has features like Tenable.io and Tenable Web App Scanning.

What needs improvement?

I wouldn't want to change anything about Tenable Nessus since I haven't found or run into any issues in Tenable Nessus.

I like Tenable since I find everything related to the solution simplified and easy to use. You can approach the online community of Tenable when you run into a problem, and there is a bunch of information available there that you can gather and use for troubleshooting purposes.

I faced some problems with Tenable Nessus when dealing with some of our company's customers in China. The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources. The solution should offer simplified data-sharing capabilities. Though we have the dashboards and can customize them, the options for customization are available in the templates provided by Tenable Nessus. It might not be possible with Tenable Nessus to add every component a person wants to a single dashboard since they can only choose whatever is available on the templates provided by Tenable Nessus. The aforementioned areas can be considered for improvement in the solution.

For how long have I used the solution?

I have been using Tenable Nessus for two months. My company operates as a reseller of the product while also having a partnership with the solution.

What do I think about the stability of the solution?

Stability-wise, I rate the solution an eight out of ten.

What do I think about the scalability of the solution?

Scalability-wise, I rate the solution an eight out of ten.

Around 90 percent of our company's customers work with Tenable Nessus.

How are customer service and support?

For the solution's technical support, our company directly seeks help from the solution's vendor in Vietnam or Singapore, who are very responsive. I rate the technical support an eight out of ten.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup of Tenable Nessus is very easy. You can get the application's installation file and implement it faster than ManageEngine, making it a simple process. I rate the initial setup of Tenable Nessus a nine out of ten.

The solution is deployed on an on-premises model.

With Tenable Nessus, you have a file, and you just need to install it. In the on-premises model of the solution, you have a dashboard or console that you go to, which is like an internal website that you have set up so that you can get access to the on-premises version of the product.

What's my experience with pricing, setup cost, and licensing?

I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price.

What other advice do I have?

Tenable Nessus is a great tool. I believe everyone should be using Tenable Nessus since it is a tool that can be used for vulnerability assessment when companies face some vulnerabilities to find security holes or threats.

I rate the overall solution a nine out of ten.

Which deployment model are you using for this solution?

On-premises

I am impressed with the tool's vulnerability scanning. 

What needs improvement?

The tool needs to upgrade asset tracking. 

For how long have I used the solution?

I am using the tool for two years. 

What do I think about the stability of the solution?

The solution is extremely stable. I would rate the tool's stability a nine out of ten.

Easy to deploy, stable, and scalable solution for vulnerability scans and assessments but can be very slow
Pros and Cons
  • "The most valuable feature is the installation of Tenable which is incredibly easy."
  • "The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."

What is our primary use case?

We use Tenable to scan all the workstations in our government environment for vulnerabilities and outdated software. The Tenable agents installed on the PCs enable us to detect any potential security risks or applications that are not up-to-date, malicious, or suspicious. This helps us ensure that all the PCs are secure and are in good posture.

What is most valuable?

The most valuable feature is the installation of Tenable which is incredibly easy. Even those without extensive technical knowledge can do it. All we need is the license and a few clicks through the installation process which is simple. Once the program is installed on all PCs and servers, we're good to go!

What needs improvement?

The solution can be annoyingly slow.

The pricing is a bit high. 

We would like to see the inclusion of penetration testing capabilities if possible.

Tenable has been mostly used in the on-premise environment, so it would be great if they could improve the transition to the cloud.

The accuracy of the vulnerability assessment needs improvement as false alarms and false positives occur often. Applications are often flagged as critical when they are actually benign. To improve user experience, there needs to be an upgrade in the accuracy of the results and a more user-friendly interface.

Sometimes it can be difficult to adjust the policies. When the solution has been previously installed. Making changes to policies requires navigating multiple steps. This process can be time-consuming and potentially confusing. Expert knowledge may be necessary in certain cases.

For how long have I used the solution?

I have been using the solution for four years.

What do I think about the stability of the solution?

There has been an improvement over the years and the solution is now extremely stable.

What do I think about the scalability of the solution?

We can easily scale up our license to support more devices. By increasing our license, we can add more workstations.

How are customer service and support?

The technical support is outstanding. We encountered some difficulties during our initial deployment, yet they persisted in helping us all day long. Their support team is very competent.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup is straightforward. 

The deployment took us two days to install the SoC on all 100 of our workstations.

What's my experience with pricing, setup cost, and licensing?

The solution is expensive. We lost bids to competing companies due to the pricing; there are cheaper alternatives to Tenable such as Rapid7 InsightVM.

What other advice do I have?

I give the solution an eight out of ten.

We have 100 workstations that all use the solution.

Which deployment model are you using for this solution?

User-friendly environment, simple to manage, and reliable
Pros and Cons
  • "The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
  • "The scalability of Tenable Nessus is good. However, it could be more flexible."

What is our primary use case?

We use Tenable Nessus to schedule test scans and work with the finding.

We have integrated Tenable Nessus with Splunk.

What is most valuable?

The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with.

For how long have I used the solution?

I have been using Tenable Nessus for approximately one year.

What do I think about the stability of the solution?

Tenable Nessus is a stable solution.

I rate the stability of Tenable Nessus a ten out of ten.

What do I think about the scalability of the solution?

The scalability of Tenable Nessus is good. However, it could be more flexible.

We have over 400 people using the solution. We plan to increase our usage, but it depends on the progress of the business.

I rate the scalability of Tenable Nessus an eight out of ten.

How are customer service and support?

The support we have for Tenable Nessus is internal. The IT teams for Tenable Nessus are in the Czech Republic for us.

Which solution did I use previously and why did I switch?

I have previously used Tenable IO.

What's my experience with pricing, setup cost, and licensing?

The price of Tenable Nessus is too expensive for each service center.

What other advice do I have?

I recommend Tenable Nessus because it's a good solution, works properly, is not complicated to administrate, is simple to manage, and is stable.

I rate Tenable Nessus a nine out of ten.

Which deployment model are you using for this solution?

Reasonably priced, reliable, and flexible
Pros and Cons
  • "It gives a holistic view of your entire environment."
  • "They should try to create an all-in-one solution."

What is our primary use case?

I primarily use the solution for network scanning. I can use it when I want to see network scanning involved with the network devices and servers. 

What is most valuable?

I love everything about Nessus. I may be biased in my rating, biased in the sense that I love using Nessus.

The usability is okay. The pricing is okay. The costs are reasonable.

The level they give you is good. It depends on the kind of scan that you want to do. There are different options there. If I want to do a PCI scan, that is available. If I want to do a scan that involves checking to see if the system patching is up to date, that is available. If I want to scan against trending vulnerabilities, I can do that, too. They have so many different options. You can streamline it to what you want, and you do your scan. 

Nessus is flexible. It gives a holistic view of your entire environment. I would go for a Nessus any day, anytime.

They have a good reporting system. I love the reporting system. The references they made in terms of recommendations are great. They can give a recommendation on how to get a particular issue fixed. 

The setup is straightforward. 

It is stable and reliable.

We can scale the product. 

What needs improvement?

They should try to create an all-in-one solution. When I say all in one, I mean something that would be cheap, where I can scan a lot in terms of web applications. Right now, this is available. However, it's a bit expensive. If users want to start scanning applications, networking devices, et cetera, they should also try and work on the pricing for those and have everything together. The web application module should be included in Tenable itself.

For how long have I used the solution?

I've used the solution over the past 13 years. I've worked with it for a long time.

What do I think about the stability of the solution?

The stability is fine. There are no bugs or glitches, and it doesn't crash or freeze. 

What do I think about the scalability of the solution?

The solution can scale as needed. 

How are customer service and support?

I've not escalated anything to technical support. 

Which solution did I use previously and why did I switch?

I'm aware of other solutions. 

What makes Nessus outstanding is the different options. There are so many scanning options. They give you the room to be flexible. You can scan your server how you want. Other options may just allow for a general scan of my system. With Nessus, I can streamline and customize my scan. 

How was the initial setup?

It is an easy solution to set up. The deployment is not lengthy. Within two hours, I had it up and running. 

There is no crazy maintenance needed. Sometimes when there are new updates, it just alerts you the moment you log into your appliance. It just alerts you and gives you room to do the updates. Sometimes it may just set automatically, and it picks the updates. When you log in, it asks for you to reinitialize your system, and you're good to go.

What's my experience with pricing, setup cost, and licensing?

The price is not bad. We are comfortable with the cost of the solution right now and with what we are paying for what we get in return. 

We just pay for the license and do not deal with any other additional fees. 

What other advice do I have?

We're using the latest version of the solution. 

When you are doing a spot check, and something rescues you a lot from disaster, you really appreciate that service. The product has really worked for me.

I highly recommend the solution.

I'd suggest new users run a POC and exhaust all the functionality and test other solutions as well. At the end of the day, compare them. Don't forget to consider budgets. Ensure that it matches what your company needs and the budget that they have for that particular solution. 

Make sure that functionality is taken into account. Some people only look at the budget and go for something cheaper and then do not have the functionality they require. 

I'd rate the solution nine out of ten.

Easy to use, and provides good visibility, but the user interface could be improved
Pros and Cons
  • "The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
  • "To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."

What is our primary use case?

Every month, I had this Windows Gold image scan. I would obtain some IP addresses, create some rules, and then run them. 

Then there were the automatic automated jobs that I and my colleagues would arrange to execute. 

They would run at night so they wouldn't interrupt the systems. 

Enter some IP addresses for workstations and servers. Some were in a highly secure zone, while others were in a separate subnet, we enter those IP addresses in and run them, scheduling them to run biweekly or weekly.

What is most valuable?

The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums. It also informs you exactly what was wrong with it. Then I believe it copies the CVS's score as well.

What needs improvement?

To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat.

For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved.

For how long have I used the solution?

I have been using Tenable Nessus for quite some time.

What do I think about the stability of the solution?

Tenable Nessus is pretty stable.

What do I think about the scalability of the solution?

Tenable Nessus is a scalable product.

How are customer service and support?

I did not deal with technical support at all.

Which solution did I use previously and why did I switch?

I used Nessus from JSON for a Gold image and vulnerability scans in my previous role.

I'm also seeking the same type of tenant for internal vulnerability scans like Qualys. 

We now use Qualys, but we haven't fully utilized its features, but I'm searching for something specialized for our internal vulnerability scan program.

How was the initial setup?

I did not set it up myself, to begin with.

What other advice do I have?

It is a good tool. It's not difficult to understand. It shouldn't be an issue as long as you know what you're doing.

I would rate Tenable Nessus a seven out of ten.

It is a very easy tool to use.

We are happy with the existing features.

We are happy with the functionality, and what we get from the tool.

I would rate their technical support a five out of five.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We are also working with Rapid7 InsightVM.

It is not as good as Rapid7 from our perspective, but it is part of our toolbox arsenal. As a result, we have it on board and solely use it internally.

How was the initial setup?

It is very easy to deploy.

This solution was deployed in 30 minutes, or less. It is very easy. It is straightforward, and out of the box.
