NenadMijatovic - PeerSpot reviewer
Efficient in vulnerability management, stable and easy to use
Vulnerability management is the most valuable feature because it lets you focus on the most critical vulnerabilities. That's the important thing. Here in Serbia, there are not so many companies that have too many firewalls inside one company. So, they usually don't buy this model for Firewall Assurance unless there is some compliance. So you can prove that your firewalls are compliant. So, that model is not so important here in Serbia. It's for bigger companies. So, they usually buy network assurance to build the model of the network and vulnerability management to focus on the most important vulnerabilities. Moreover, Skybox can collect data for many vendors. From the endpoint protection vendors to the network equipment vendors to other security vendors. So, it supports more than one hundred vendors to collect data from them.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This type of tool does a great job of reaching into those other devices producing risk recommendations, compliance recommendations, and a single plane of glass to do your queries, so you can find where these rules might exist."
"We are currently working on rule review and compliance. The logging features are good."
"It can be integrated with a vulnerability management solution. When a client comes, apart from pitching network and firewall change management, we are recommending having vulnerability management. So, rather than just having the audit of the firewall, they can integrate it with their vulnerability management solution, which could be Rapid7, Qualys, or any other solution. This provides them the most value out of the platform. That is the way we are approaching our customer base."
"The revalidation and policy recertifications are most valuable."
"It has a good policy management feature and can provide customers with good quality outputs."
"The most valuable feature is the compliance, whether it's access compliance or the configuration compliance, to make sure that all of our devices are configured as they're supposed to be, to limit access as much possible, to follow least-access guidelines."
"The product's most valuable feature is vulnerability management."
"The solution's most valuable and unique assets are the vulnerability management and change management solutions because they identify mistakes in the network before implementation which reduces risks."
"Tenable Nessus is an absolutely stable and fantastic product."
"The solution is great for scanning servers."
"Tenable Nessus has provided increased visibility across the organization's servers."
"The reports are pretty nice and easy to understand."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"Makes ransomware checking and OS auditing and implementation relatively easy."
"Tenable Nessus is cheap and flexible."
 

Cons

"The vendor's support is terrible."
"The primary room for improvement would be to enable a web interface, which is not something which is there in the product. This is supposed to have come a year, a year and a half ago, but still has failed to come out. It still needs a client application to be installed on a workstation to be able to access that server and then run these reports. So I cannot extend that access to anybody. It has to be one administrator all the time. So unlike a web interface, where you can give multiple users simultaneous access and generate the various reports, that isn't a possibility at the moment."
"There are multiple dashboards but no custom dashboard. It would be good to include a custom dashboard so that we can actually choose which field and what kinds of things we want to look at."
"The support could be improved."
"The solution does not support certain devices or vendors in some regions or countries due to regulations."
"Skybox should improve their UX features by making them easier to use."
"Reporting. A lot of the reports, out of the box, are limited to a certain number of either configuration violations or access rule violations. So when you first set up a new firewall to be monitored by Skybox, you don't get a real full report. You have to really tweak it to get everything."
"The solution needs improvement in firewall configuration checks. I would also like to see more configuration checks for Forcepoint and for other non-supported firewalls."
"Online learning could be a bit better."
"We use credentialed scans. They need more permissions and more changes or settings on Windows and Linux."
"The product must be more comprehensive."
"We'd like to see more integration potential within the solution."
"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."
"The professional version is not very scalable."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"Tenable Nessus could improve the reporting."
 

Pricing and Cost Advice

"Skybox comes with extra licenses and has a change management license. The licenses are expensive, but they come with extra value."
"The price of the Skybox Security Suite can be expensive."
"I think the price is fair."
"Currently, the licensing costs me about $300 USD for the year. This is a huge amount for my environment."
"The product's pricing is excellent value. In terms of licensing, make sure you understand your network components, all your hops through your network, thoroughly, before you decide on the total cost. If you want to do point-to-point flow analysis and such, you need to have the configuration of all the devices in between point A and point B. A lot of people don't realize all their network components until they start using this product."
"I think for the cost, what we got definitely is worth it. The only caution I would give is that whenever you license for Firewall Assurance at the same time, for some weird reason, you have to get one Network Assurance license, just to manage one firewall. That's a little bit of overkill. But otherwise, in general, the pricing is fairly okay."
"The licensing fee is paid yearly and is approximately $100,000."
"Skybox Security Suite has indeed helped us reduce costs. The prices of AlgoSec and Skybox Security Suite are approximately 50 percent different. The tool may require special vendor support from abroad, resulting in slightly higher costs. Its pricing is in the middle."
"It has a fair cost and very good cost-benefit ratio."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"Our organization is huge so our license costs $30,000."
