Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Quotes from Members

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

Pros

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"I have experience with it on my attack stations, and it's pretty good to optimize. Personally, I think Nessus is quite a good product."
"The solution is very stable."
"Tenable Nessus has provided increased visibility across the organization's servers."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"Overall Zoom is a good solution."
"Tenable integrates well with other solutions such as SIEM and batch management."
"It's scalable."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
"My advice for those considering Tenable Security Center is to note the benefit of upgrading vulnerable devices."
"The initial setup process is simple."
"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."
"The tool's dashboard and reporting capabilities match our company's needs since we are able to modify the basic view to create a new dashboard, and it works out very well for our needs."
"Their overall cost of service is pretty good."
"It is a very good and user-friendly product."
"Tenable.sc is user-friendly."
"Has a great advanced scanning feature."
 

Cons

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"We'd like to see the solution embrace more user-friendliness."
"It would be nice for the professional module to include some of the reports available in the expert module."
"The reporting is a bit cumbersome."
"From my point of view the solution basically is not for the big enterprise."
"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."
"You can scale Nessus to the extent that you can afford it. You need to have a license for every device you scan. As long as you can afford the increased costs, you won't have a problem scaling it."
"The price and scalability of the solution could improve."
"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."
"Current web page needs improvement, slows down processes."
"It's good at creating information, it's good creating dashboards, it's good at creating reports, but if you want to take that reporting metadata and put it into another tool, that is a little bit lacking."
"I think the vendor training provided for Tenable.sc could be a lower price. It's quite expensive for the training."
"I will say it's a lot slower compared to an MS scan. It takes so much longer, so the performance could definitely be worked on."
"We are facing some challenges related to our channel."
"At times we have had the typical bugs."
"The solution needs to improve its support. I would like to see a bird's eye view of my network architecture. I would also like to see the continuous view feature in the tool."
"For downloading reports, we have to go to the scan and then we have to go to the reports and download the Excel or CSV or PDF. I think these menus and clicks can be minimized."
 

Pricing and Cost Advice

Information not available
"In general, it is extremely expensive."
"The solution is worth the cost. It's a good investment."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"The price of the solution is reasonable."
"The price of Tenable Nessus is too expensive for each service center."
"The price is reasonable."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"Compared to other companies or other products it could maybe be a little bit less, but the price is okay. I would say it's not very expensive."
"The pricing depends upon the number of IPs."
"Tenable.sc is more expensive than its competitors."
"The tool provides competitive pricing."
"Tenable is open-source."
"We're a Fortune 500 company... our licensing costs [are] in the seven figures."
"We pay around 60,000 on a yearly basis."
"The tool costs around 15,000 Saudi riyals monthly."
