Easy to use with efficient vulnerability reporting and team collaboration
Use case, so all the reports from GitLeaks, DefectDojo, GitLeaks or dependency check or Trivy, they make reports, and we send this report to DefectDojo to have CVMs, Central Vulnerability Management. DefectDojo is Central Vulnerability Management. If you have a dashboard to set, we have…

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Quotes from Members

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

Pros

"With the pipeline of detection and DefectDojo, we are able to see the real vulnerabilities, and we fix them."
"It is a mature tool."
"The solution is worth the cost; it's a good investment."
"User friendly and good dashboards."
"We have done code scanning for a long period because as a company, we do DevOps as part of our development life cycle."
"The features of Tenable Nessus that I have found most valuable are its reliability and its ability to collate a dependable output, where we are able to get the same vulnerability when we test manually. The output is quite reliable."
"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."
"The vulnerability scanner is the most valuable feature."
"The initial setup is very straightforward."
 

Cons

"We need something to notify the team responsible for a product when vulnerabilities are found."
"One area that has room for improvement is the reporting. I'm preparing reports for Windows and Linux machines, etc. Currently, I'm collecting three or four reports and turning them into one report."
"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming."
"We find that some devices aren't pinged and the scans aren't done properly."
"We feel the solution's technical support to be very bad."
"The solution should be able to support more devices."
"We'd like to see the solution embrace more user-friendliness."
"The support from Tenable Nessus is okay. However, they are sometimes slow and can take days to respond."
"The professional version is not very scalable."
 

Pricing and Cost Advice

Information not available
"Our organization is huge so our license costs $30,000."
"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 Tenable Nessus could improve, it is expensive."
"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."
"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."
"I would like to see better discounts."
"The solution is worth the cost. It's a good investment."
"The price of the solution is reasonable."
