Nessus was used to scan vulnerabilities and compliances in our clients' networks and with this, carry out the remediation process through constant cycles in time until threats to the network are considerably reduced. The environments are small business networks (less than 50 employees), and so far there have been no major impediments in the scans performed.

Nessus has greatly improved the security of our clients' networks. The comfortable management of their systems makes it easier for engineers to use the codes for each vulnerability or compliance. Deploying the server to launch the scans is very easy, and only the necessary prerequisites for scanning should be fulfilled. Nessus has been very valuable to the company.

The comprehensive coverage offered by Nessus has been the most remarkable; it really does everything that has been asked of the software.

It's great, the possibility of automating implementations and really your database is immense for all the compliances and vulnerabilities.

Tenable University is great and allows to train all the personnel in charge of making the scans in an optimal and effective way.

• I think that the next versions could improve the graphical interface to make more intuitive the management of the reports. 
• Additionally, it could include better features in the vulnerability scan at the language level.

Nessus is very stable and really works in diverse environments without any difficulty. The most important thing is to establish the necessary requirements.

Scalability of this type of software does not seem so relevant.

The Tenable support is very good and has really solved in a timely manner the problems that have occurred in the various projects.

In the company, Qualys was used, and it was not possible to manage the projects with this tool.

Quite simple and comfortable.

Internal team.

Phenomenal.

The costs are not high, considering all the support and service offered by Tenable.

Scans using agents are very useful, and taking advantage of them is the best way to take advantage of the tool.

We are a company that provides cloud migration services. We help companies to migrate to the public cloud. When our customers want to migrate applications, they're worried about the security aspect in the cloud. So we are trying to see how the application security that is on-premises can be migrated to the cloud.

We don't have any particular solution, we are working with a few options. The customer selects what best suits their needs. If we have a program, we work with that.

It's not specific to what we are working with.

We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle. We like scanning the ports and security as well as application-level security.

Some of our customers are operating on the cloud as well as on-premises.

We would like to have the option of using the solution for the cloud as well as on-premises with the same license at the same time. That would be very helpful.

We have used this solution for three or four projects in the last two years.

We are always working with the latest version.

The stability varies on the version that you are using. 

We have not had any problems with stability with what we are using. It's been stable and we have never been faced with any stability issues.

We have used this for an enterprise cloud application, which is much smaller with hundreds of users. It's pretty scalable. We have not had any challenges so far. 

I don't know the limits of scalability because we haven't trialed it fully. But for the enterprise application that we use, we didn't find any issue with scalability.

We have contacted technical support, once or twice when we have had issues with respect to some plugin related clarification. 

There are times where the solution doesn't work out of the box, and we have to install some plugins. We needed some assistance with this.

They are good, but the response resolution takes a bit of time. It would say that it's still within an acceptable response time. Within a few hours, they will get back to you with a solution.

The initial setup is pretty easy.

When we use the scales we find it to be easy.

In our experience a complete deployment and start-up, it takes only a few hours.

In some cases, we deploy on-premises because the customer is still evaluating the readiness to go to the cloud. 

A few of our customers are already on the cloud, and others are migrating. We have deployed on both models.

With my experience, I would definitely recommend it. This is the only tool we have used recently.

I would rate this solution an eight out of ten.

We use Tenable Nessus for asset and vulnerability management.

The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration.

There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard. Additionally, they should include more learning material to know about the product.

We have been using Tenable Nessus for one year.

The product has good stability.

We have more than 50 Tenable Nessus users in our organization. It is a scalable platform.

Tenable Nessus is easy to deploy and manage.

I recommend Tenable Nessus to others and rate it a seven out of ten.

We're using Tenable Nessus to manage vulnerabilities.

What I like most about Tenable Nessus is its vulnerability scanning feature.

A room for improvement which I see in Tenable Nessus is the inventory management function.

I've been working with Tenable Nessus for two years now.

I'm satisfied with the stability of Tenable Nessus.

We have not tried to scale up Tenable Nessus. The number of users we have when we started using it is still the same.

Technical support for this solution was good. They were responsive.

The initial setup for this solution was easy.

We implemented Tenable Nessus through a vendor team, and the process took one month to complete. They were good.

This solution is affordable. We pay a standard fee. We pay for the license yearly.

I work with different products, e.g. firewalls, PAM technology, antivirus, WAF, and proxy. I'm handling information security in the government, not as a consultant. I deal with government procedures.

We deployed this solution on hardware, on VM.

We have 10 users of Tenable Nessus, and they are a mix of engineers and managers.

I'm scoring Tenable Nessus a ten out of ten.

We use it for vulnerability management. We have the latest version because we're using it in the cloud right now. I have a public cloud and a private cloud version.

When we do our scans, I'm able to give full reports of what's vulnerable per device. I could group them and say, "Hey, here's a vulnerability in the infrastructure. Here's all the host that needs to be addressed," by showing the report. When I give a report or a request for change, I would include the report so that they are undisputed. Instead of the sys admins giving the excuse of, "Hey, we don't have enough time," or, "We've already done it," or some other poor excuse, now I have a report behind it that says, "Hey, you're vulnerable with this. Here's the CVE, and here's the POC of the CVE," and then if I want to be a little bit more obnoxious, I provide them the POC that I ran with the proof that the POC is there, and then I'm able to say, "Hey, you need to patch this now."

My executives now are able to say, "Hey, you know what? The ISO gave you a directive to patch this with proof. Why haven't you done it?" Because now, as we know, all C-levels are ultimately responsible. If you have an ISO that is interfacing with sys admins saying, "Hey, here's a change that you need to patch it. Here's my proof that even has POC with proof and the report," then there is no benign, "Why haven't you done it?"

I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for.

The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses. If I wanted to put it in the lab in my network at work, and I'm doing a test project that has over 30 nodes in it, I can't use the free version of Nessus to scan it because there are only 16 IP addresses. I can't get an accurate scan. The biggest thing with all the cybersecurity tools out there nowadays, especially in 2020, is that there's a rush to get a lot of skilled cybersecurity analysts out there. Some of these companies need to realize that a lot of us are working from home and doing proof of concepts, and some of them don't even offer trials, or you get a trial and it is only 16 IP addresses. I can't really do anything with it past 16. I'm either guessing or I'm doing double work to do my scans. Let's say there was a license for 50 users or 50 IP addresses. I would spend about 200 bucks for that license to accomplish my job. This is the biggest complaint I have as of right now with all cybersecurity tools, including Rapid7, out there, especially if I'm in a company that is trying to build its cybersecurity program. How am I going to tell my boss, who has no real budget of what he needs to build his cybersecurity program, to go spend over $100,000 for a tool he has never seen, whereas, it would pack the punch if I could say, "Let me spend 200 bucks for a 50 user IP address license of this product, do a proof of concept to scan 50 nodes, and provide the reason for why we need it." I've been a director, and now I'm an ISO. When I was a director, I had a budget for an IT department, so I know how budgets work. As an ISO, the only thing that's missing from my C-level is I don't have to deal with employees and budgets, but I have everything else. It's hard for me to build the program and say, "Hey, I need these tools." If I can't get a trial, I would scratch that off the list and find something else.

I'm trying to set up Tenable.io to do external PCI scans. The documentation says to put in your IP addresses or your external IP addresses. However, if the IP address is not routable, then it says that you have to use an internal agent to scan. This means that you set up a Nessus agent internally and scan, which makes sense. However, it doesn't work because when you use the plugin and tell it that it is a PCI external, it says, "You cannot use an internal agent to scan external." The documentation needs to be a little bit more clear about that. It needs to say if you're using the PCI external plugin, all IP addresses must be external and routable. It should tell the person who's setting it up, "Wait a minute. If you have an MPLS network and you're in a multi-tenant environment and the people who hold the network schema only provide you with the IP addresses just for your tenant, then you are not going to know what the actual true IP address that Tenable needs to do a PCI scan."

I've been working on Tenable.io to set up PCI scans for the last ten days. I have been going back and forth to the network thinking I need this or that only to find out that I'm teaching their team, "Hey, you know what, guys? I need you to look past your MPLS network. I need you to go to the edge's edge. Here's who you need to ask to give me the whitelist to allow here." I had the blurb that says the plugin for external PCI must be reachable, and you cannot use an internal agent. I could have cut a few days because I thought I had it, but then when I ran it, it said that you can't run it this way. I wasted a few hours in a day.

In terms of new features, it doesn't require new features. It is a tool that has been out there for years. It is used in the cybersecurity community. It has got the CV database in it, and there are other plugins that you could pass through. It has got APIs you can attach to it. They can just improve the database and continue adding to the database and the plugins to make sure those don't have false positives. If you're a restaurant and you focus on fried chicken, you have no business doing hamburgers.

I've been using Nessus for about eight years.

Internally, it is stable. Externally also, from what I've seen, it is stable. The only problem that I've had with it was if you have a network and internet blip, you get disconnected, but that happens with anything. Right now, I would say that a lot of cloud companies are having problems because COVID has got a lot of people working from home remotely in VPN. This is the biggest problem we have. You went from 35 people using VPN to over 2,000 people using VPN. You're trying to go to a cloud that wasn't set up for VPN, or you don't have the necessary routes or bandwidth to it. The average person is going to say, "This cloud application sucks." It doesn't really suck. It means that you don't have enough bandwidth in your infrastructure.

We haven't had to scale it yet. We haven't scaled internal Nessus because we have our own version of it. I'm not sure how many IP addresses we're feeding, but I know we only have one server. I looked at the processes, and it's only doing 50% of the process.

We have 13 people who are capable or licensed to use it, which would be all of our risk management information, information security, and risk management office, but I would say only half or about six of us are actually using it daily.

I've used the tech support a couple of times. I would say they are very good because they were able to say, "Hey, let's stop the chatting. Let's get on a Webex, and we will Webex you and ask the questions directly." They were able to get to the engineers on the Webex at the same time, and within 30 minutes, they solved our problem. I would rate them a ten out of ten.

If I was installing Nessus just by itself, it is straightforward simply because I've done it before. If you're setting up Nessus from the cloud version, there's a little bit more to it because, for one, it's in the cloud version, and you got to open up ports for your network. You got network people who get all scary because they don't understand what you're doing. Other than that, once you get it set up, then it is pretty much straightforward.

Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly.

The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job.

The advice would be definitely doing your proof of concept because that's what you're going to need for your buy-in for your upper management because it is going to cost some money. I would do a hybrid version, where your own Nessus is internal, and then you have your cloud. If you lose connection to the internet, you could still run an internal Nessus scan to save the scan and then input the scan into Tenable.sc. Do your proof of concepts, get your reports, and use your proof of concepts when you do your presentation to upper management to purchase. If you use your own nodes and your own network as your proof of concept, it gives them an eye view of, "Hey, we're vulnerable because of this, and here's the tool that did it." To me, that was a better selling point because it was real. It wasn't the demo data. Once you have purchased it and get it all set up, use it continuously, meaning include your scanned reports with your change control. This way, it shuts all the administrators who have been there over 20 years and say, "Hey, I don't want to patch right now because it takes the network down." Yes, it's going to take the network down. However, the longer you wait, the more vulnerable you are because if I'm doing change requests every week, and I'm calling on more and more risk and you start to find the same nodes in the same reports, then somebody up high is going to say to the network administrator guy to fix it.

I would rate Tenable Nessus a ten out of ten right now. If you had asked me last year, Rapid7 would have been the same and on top, but now that I've been using Tenable and I'm comparing the jobs that I'm doing right now, Tenable is cut and clear to what the report is saying. My favorite report is the VPR report. Instead of just looking at CVS numbers, it has a VPR report that ranks, whereas, in Rapid7, it's just focused on CVS. It is CVS version 2 or 3, which kind of gets confusing. For example, in Tenable, I can run a scheduled scan and have my report, but let's say, for instance, I did patching in the middle before my scheduled scan. I could kick off a new scan specifically for that vulnerability and get a report, whereas, in Rapid7, you could not easily do that. Therefore, you were stuck waiting for the scan to go again and to see if your mitigation efforts fixed it.

I evaluated, set up, and implemented Tenable Nessus for a client. They had four firewalls, about 500 endpoints, two servers, and one database server.

I like the fact that it was not expensive. I like that it's user-friendly.

It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features.

I have been using Tenable Nessus for about six months.

On a scale from one to ten, I would give stability a seven.

The initial setup is straightforward. We can deploy this solution within a week.

On a scale from one to ten, I would give the initial setup a seven.

We implemented this solution. 

Tenable Nessus is affordable. 

On a scale from one to ten, I would give pricing a ten.

I would tell potential users that Tenable Nessus is suitable for device security.

On a scale from one to ten, I would give Tenable Nessus a seven.
