Doesn’t identify threats and vulnerabilities, and the reports are quite useless

Unlimited assets for one price and quick, agentless results
I implement the solution as a vulnerability management tool for client use cases. It can be used for public factors because it sits right where you have tie in and bleeds over or in between other tools as another piece in the EDR puzzle. The solution identifies vulnerabilities, applies patches, and…

Quotes from Members

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

Pros

"Penetration testing and scans are useful features."
"The most valuable feature of Tenable Nessus is website scanning."
"The trial version is very good for testing whether it will suit your needs."
"User friendly and good dashboards."
"It provides multiple recommendations towards the remedy of vulnerabilities."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"Tenable Nessus is cheap and flexible."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"It is a mature tool."
 

Cons

"The reports are quite useless."
"We have had some false positives in the past, which we hope can improve in the future."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"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."
"They need more flexible pricing."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"The reporting is a bit cumbersome."
"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."
